chairman’s statement 
overview 
i am pleased to report encouraging results for the year ended 30 september 2011 especially considering the adverse 
weather earlier in the year and indeed the apprehension surrounding the government’s expenditure programmes the 
group continues to prove its resilience to fluctuating market conditions by maintaining its focus in the regulated 
environment where legislation is a key driver 
we have successfully achieved our objectives in the year in terms of organic growth and in terms of acquisitions 
achieving market expectations on margin and turnover both of the acquisitions a h allen and rds are being 
successfully integrated into the consulting business and are already producing positive results the group 
successfully raised £23m in a share placing during the year predominantly to fund these acquisitions 
 
strategy 
this is the second year of the ‘protecting lives creating value’ strategy which aims to deliver shareholder value by 
broadening our service offer and sustaining high quality repeatable revenues from large bluechip customers in the 
regulated and highhazard service sectors the group’s customer base now consists predominantly of large private 
and public sector organisations which place a high value on protecting the health of their customers staff and 
reputation while conditions in the wider economy are expected to remain difficult your board believes that the 
increasingly stringent regulation surrounding hazardous waste management will require customers to continue to 
prioritise nondiscretionary expenditure on facilities maintenance and regulatory compliance 
our ambition is to grow revenues to more than £100m per year within two years it is management’s view that whilst 
this could possibly be achieved organically it is most likely to come about through acquisitions and the board is 
actively exploring some options silverdell will only consider acquisitions which meet strict criteria they will be 
limited to organisations providing services which complement our group’s current service offer to highly regulated 
industrial sectors such as nuclear oil gas and energy as well as niche bolton consulting businesses and must be 
earnings enhancing within the first year 
silverdell has developed into a stable and resilient business in recognition of this fact and as a mark of our 
confidence in the future of the group we carried out a capital reduction exercise during the year which enables a 
dividend to be paid for the first time the board has determined that it will have a cautious but progressive dividend 
policy and it is our intention to pay our maiden dividend during 2012 
 
results 
revenues for the year ended 30 september 2011 were £597m 2010 £567m with adjusted ebitda of £41m 
2010 £39m and adjusted pretax profit of £30m 2010 £25m the order book at 31 october 2011 remains 
strong at £107m 2010 £62m at 31 october 2010 with £36m secured for 2012 at the year end the company’s net 
debt was £53m 2010£43m as the group required additional capital to support its growth particularly during the 
second half of the year 
 
 
board  people 
we now have a dynamic cohesive and committed management team led by our ceo sean nutley who have worked 
extremely hard over the last two years in revitalising the group and ensuring strong ties across each of the three 
principal divisions whilst maintaining their individual accountability and strict control disciplines i believe we are 
now in a strong position to take the group forward to its next stage of development 
in june matt griggs took over as md of the consulting business redhills and is successfully overseeing the 
integration of the two new acquisitions in november 2011 john potts joined the group from hertel to lead our 
industrial services division  silverdell plc

board  people continued 
we remain a direct employer of our workforce such that their inherent skills are maintained and developed in the 
business providing an excellent basis for the training and development of future management coupled with the ease 
with which we maintain our licences to operate  
on behalf of the board i would like to express our gratitude and thank the management team and everyone in the 
group for their hard work dedication and commitment to our strategy during during the past year we have 
continued to deliver a good set of results despite the challenging economic climate around us  
 
summary 
silverdell performed robustly in the year ended 30 september 2011 the group has delivered significant growth both 
organically and by acquisition during the year and particularly during the last six months we believe that we now 
have a stable dynamic and flexible business which is very well positioned to deliver further growth and value to our 
shareholders as well as giving us confidence in our ability to pay a dividend during 2012

our business  drivers for success 
 
since 2009 our group has transformed from being principally a specialist in the management and removal of asbestos 
to become a broad based environmental support services provider with operations focused on highly regulated high
hazard markets  
 
we expanded the skills capabilities and capacities we gained working with asbestos and applied them to similarly 
sensitive markets  nuclear defence and energy today we have migrated upstream to contend as a specialist 
contractor against competitors many times our size  
 
driving our success are 
 
our business focus and organisational structure 
 
awareness of the risks posed by hazardous substances to environmental health have never been higher the 
increasing requirements of public and workplace health and safety protection legislation in the uk europe and 
worldwide mean that expenditure on the management control and remediation of such substances can no longer be 
considered discretionary prominent publicity is given to events in which hazardous materials have failed to be 
contained 
 
environmental hazards are a fact of life although the use of asbestos was banned in the uk in 1999 its legacy will 
continue until 2050 fourteen million homes were built in the uk between 194599 some 19500 schools and 
500000 uk workplaces are estimated to have highhazard regulated asbestos containing materials acms in their 
structures 18m uk workers and tradespeople are estimated to be exposed to environmental asbestos every year 
annual deaths from asbestos related illnesses are predicted to peak at 5000 in 2015  
 
to counteract such hazards we have increased our range of capabilities and expanded our capacity to become a full 
service single source supplier of premium complementary high hazard regulated environmental support services  
from onsite consulting through to construction and remediation serving customers throughout the private and public 
sectors our skills are transferable sector to sector market to market our geographic reach extends throughout the 
uk and our scale enables us to follow our customers internationally 
 
 
our people 
 
our people are vital to our success we recruit people who share our work ethic and values and who understand and 
are committed to the duty of care we owe our customers

our business  drivers for success 
 
whatever their level of skill or experience on joining we aim to help every one to reach their maximum potential and 
make a career with us on joining everyone undertakes a training needs assessment site staff progress through a 3  
tiered  ‘bronze’ ‘silver’ and ‘gold’ standard  development programme designed to increase the level of skills and 
competency and equip the individual to master tasks of different risk and complexity  
 
 
specialist training in working with hazardous materials at height or in confined spaces is provided by our own 
academy safe training and as needed by external providers high potential individuals participate in a fasttrack 
development programme in which exceptional people can progress from new operative to manager within four years 
operative supervisor or manager we provide a programme of continuing development designed to help them reach 
their full potential 
 
by training our people to the highest standards helping them to realise their potential and providing them with 
satisfying careers and industry leading benefits we aim to retain the best workforce in our industry 
 
 
barriers to entry 
 
we work in a highly regulated sector where legislative barriers to entry are increasingly restrictive and few can 
match our level of capability expertise and experience 
 
in addition significant nonlegislative barriers such as necessary security clearances insurance cover accreditations 
and a proven track record resources and capacity in such projects act to restrict access to our markets 
 
 
legislation 
 
increasingly stringent legislation while restricting entry to our markets is also acting to increase demand for our 
services the introduction of a ‘duty to manage’ under the uk control of asbestos regulations car in 2006 has 
increased demand for our consulting services the eu ruling in 2011 requiring the uk to implement the asbestos 
worker protection directive in full will necessitate many tradespeople receiving specialist training in working with 
asbestos while a 2011 ruling of the uk supreme court will open the path to action against employers and building 
owners by mesothelioma victims and increase attention to asbestos management and remediation 
 
 
reputation and credibility 
 
legislation and media attention have increased market sensitivity to compliance and risk management leading to a 
greater focus on health and safety issues and expenditure by business on corporate social responsibility programmes 
 
with our specialist focus track record of project delivery and ability to engage and work with our customers to create 
longterm relationships we are well positioned to succeed we are one of very few specialist environmental services 
businesses capable of putting the right people with the right skills in the right place at the right time and able to 
respond to the needs of those customers seeking the simplicity and certainty of a single source solution

chief executive’s statement  
overview 
a strong foundation for profitable growth 
silverdell operates in two distinct markets in the uk the general domestic refurbishment and construction related 
market and the larger industrial support services market predominantly involved in the petrochemical and nuclear 
sectors both of which require a high degree of regulatory control the skills processes and importantly the culture 
that our operating teams have developed in providing asbestos services lend themselves to the handling and 
management of all hazardous materials in a safe and compliant manner where incidents could have dramatic 
repercussions on the operating efficiency of clients’ establishments and damage to their reputations to these 
customers we provide reassurance and peace of mind 
the group is the largest quoted specialist supplier of asbestos support services in the uk but despite that has only a 
small proportion of the wider industrial support services sector this is where we believe the next step in our growth 
strategy to be however because of our proven and wellregarded track record of delivering services in hazardous 
conditions we are a trusted and longstanding supplier to major companies in the nuclear defence petrochemical and 
energy sectors we are now actively building on this position to create new opportunities for growth in these sectors 
both in the uk and abroad we believe that the successful implementation of this strategy will help fulfil our 
ambition to increase the critical mass of the business and secure annual turnover in excess of £100m 
strategic review 
introduction 
we are in the second year of the strategy building the group up from the parlous financial state which existed in 
2009 the change in culture which has resulted from our pursuit of our “protecting lives creating value” strategy is 
providing improved cohesion better delivery of client services and positioning the group well for further growth  
increasingly our key customers are seeking to appoint partners that are capable of offering a single source solution to 
their service needs in a highly regulated market they are seeking to achieve longterm certainty and peace of mind 
by appointing reliable proven supply chain partners on a framework contract basis we operate in markets where 
there are very high barriers to entry and which therefore favour longestablished reputable companies such as 
silverdell plc  
furthermore we differentiate ourselves from our competitors by striving to provide a premium service across a 
spectrum of complementary services from onsite consulting through to remediation serving all sectors and public 
and private customers 
‘protecting lives creating value’ is a fourpronged strategy that is designed to enable our group to consolidate   its 
position as the uk’s leading provider of specialist environmental support services and take a larger share of the uk 
industrial support services market but with the capacity to follow our customers overseas or pursue opportunities in 
potentially attractive territories worldwide where similar legislation is in place 
objectives 
for the year ahead we plan to further strengthen the silverdell group and create shareholder value through 
 clearly demonstrating our position as a leading provider of  services in highhazard regulated environments 
through our competence and track record to customers suppliers employees and investors in order to 
differentiate ourselves from the competition and make silverdell their services partner of choice 
 developing our product and geographic capability through new service offerings through acquisition and by 
organic growth 
 
 improving existing client relationships by offering bundled services with unmatched quality 
 
 continuing to improve systems cost efficiencies and cash management across the group

chief executive’s statement continued 
 
objectives continued 
in order to achieve this we continue our strategic approach to drive improving performance through 
 
 further development of our capabilities in regulated environmental and compliance markets other than 
asbestos management 
 development of our position in the industrial and power generation markets through securing longerterm      
framework contracts 
 development of our existing customer relationships to generate new business in areas such as specialist 
scaffolding insulation and specialist coatings training consulting and compliance  
 increasing our capability in hazardous materials consulting 
 
back in june 2010 our board set the group a number of challenging targets for the mediumterm 
 
 to grow our order book ahead of organic revenue growth  
 to drive revenue growth year on year ahead of market growth 
 to grow the ebitda margin to 10  
 to maintain working capital at not more than one month’s revenue 
 to grow the consulting business to 15 of group revenues 
 
i am pleased to report that we are making considerable progress in most of these areas in particular recent months 
have seen our order book increase by over 70 against last year while revenues are 6 higher yearonyear ebitda 
margins year on year continue to improve although the step to 10 will require a step change in our volumes to 
reduce the dilutive effect of our fixed overhead 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  silverdell plc

chief executive’s statement continued 
 
what we said what we’ve done the future 
grow our order book ahead of organic 
revenue growth  
achieved order book has risen 73 
to £107m 2010 £62m 
continue focus on winning high 
margin consulting and high value 
framework contracts increasing our 
penetration of the wider industrial 
support services market  
drive revenue growth year on year 
ahead of market growth 
achieved group turnover increased 
by 5 to £597m 2010 £567m 
accelerate revenue growth to meet 
ambition of £100m within two years 
through organic growth acquisition 
and international expansion 
grow the ebitda margin to 10 progress while ebitda increased 
5 to £41m 2010 £39m the 
margin remains at 7  
continue to focus on order book and 
revenue growth while bearing down on 
costs and seeking cost synergies 
throughout the business 
maintain working capital at not more 
than one month’s revenue 
this has been challenged by the 
growth that has been experienced as 
a direct labour employer anything 
above modest growth requires 
additional working capital 
we will strive to optimise cash through 
improving terms wherever possible 
grow the consulting business to 15 
of group revenues 
achieved consulting now accounts 
for 18 of revenues on a running rate 
basis 
continue the assimilation of ah allen 
and rds into the business and pursuit 
of framework opportunities 
 
earnings before interest tax depreciation and amortisation and also before nonrecurring costs and sharebased payments 
 
most importantly silverdell is a very different group today than it was two years ago then despite having excellent 
site operations the group had considerable debt and profits were at an alltime low despite extremely difficult 
market conditions the group has been strengthened financially and operationally renegotiating its facilities and 
securing more funds from the market completely restructuring its senior management team and driving cultural and 
financial disciplines into the three core divisions whilst ensuring cooperation and cohesion with no loss of 
accountability  
two years on the decisive management actions we have taken have transformed silverdell into a robust growing 
business with stable and flexible financing  
we have done all this while maintaining our bestinclass operational reputation our credibility is now such that we 
increasingly find ourselves competing on a ‘tier 1’ basis for contracts in which we contract directly with the end 
customer where before we might only have been considered as a subcontractor 
the successful £23m fundraising we undertook in august to fund the acquisition of rds is testimony to our 
transformation  
 
 
  silverdell plc  
 
 
14 
 
chief executive’s statement continued 
 
acquisitions 
during the year we completed two acquisitions to strengthen our environmental consulting offering and having 
completed the acquisitions the key to success has been the smooth integration of the businesses into the group in 
april we purchased a h allen limited “a h allen” based in the north east the integration plan is going well and 
is on plan at the end of august 2011 we purchased rds asbestos management consultants uk limited “rds” 
which will strengthen our presence in the retail sector  the management teams are working together to ensure its 
smooth integration  
both ah allen and rds bring additional capacity and considerable expertise to the group’s consulting offering 
our consulting team is now over 180 strong compared to around 100 this time last year and so we expect both 
acquisitions to be earnings accretive with immediate effect  
 
summary and outlook 
our “protecting lives creating value” strategy has effectively prepared our group for the next stage of growth the 
board is currently developing the plan for the next phase of our group’s development which will be unveiled within 
the next six months  
the last two years has seen the group recover from a low point to build a stable foundation for growth and start to 
deliver that growth through some significant business wins the next phase of growth will see the group increase in 
reputation revenues and profits to become an established and high quality provider of hazardous industrial services 
with a truly international capability

chief executive’s statement continued 
 
operational review continued 
revenues in 2011 operating margins in this segment were 69 in 2011 up from 62 in 2010 driven by operating 
cost efficiencies 
consulting has had a strong year boosted in the second half by two acquisitions which have improved both our 
capability and capacity external consulting revenues rose by 32 to £82m 2010 £62m nearly all of which is 
generated through framework contracts profitability also improved as a result of better overhead efficiency with the 
operating profit margin increasing by 09 ppts to 153 2010 144 the acquisitions will drive further 
improvements in revenue and profitability in 2012 
 excluding amortisation sharebased payments and nonrecurring items 
 
public sector 
there is a substantial asbestos legacy across the whole range of public sector property including local government 
buildings and social housing schools colleges and hospitals as well as defence establishments the public sector 
spend on maintenance and refurbishment projects exceeds £20bn per year and this is driven by regulatory 
requirements  
notwithstanding the coalition government’s comprehensive spending review in october 2010 and the associated 
freezes or reductions in a number of capital projects silverdell has seen public sector revenues rise by 13 during the 
year the share of total remediation revenues generated by public sector work increased to 44 in 2011 2010 39 
whilst the share of consulting revenues was 38 2010 52  
underlying public sector revenues in consulting were flat year on year with the principal elements of organic and 
acquisition growth in consulting delivering revenues predominantly in the private sectors    
 
local authority and housing  
2011 has been another year of success in winning local authority and housing framework contracts with the share of 
total remediation revenues rising to 12 201011 towards the end of the year we won a contract to survey and 
remediate 30000 homes over three years working for a consortium of registered social landlords  
we continued to win new contracts with social landlords such as peabody as well as several local housing 
authorities however with more significant revenue growth in other areas local authority revenues fell to 14 of our 
total consulting revenues 2010 21  
health and education 
health and education comprised 11 2010 11 of our remediation revenues particular success has been 
achieved in working with a major nhs trust in south wales the strength of this relationship driven by our 
understanding of the customer’s needs has opened the door to further opportunities with nhs trusts elsewhere in 
wales we are also the incumbent asbestos services provider for a number of russell group universities which have 
diverse property portfolios across a wide regional spread 
health and education work made up 15 of consulting revenues 2010 21 with notable work wins with a 
number of russell group universities providing survey and management services across their entire university 
estates 
 
defence 
the defence share of revenues for remediation was 21 201017 during 2011 we developed excellent 
relationships with the atomic weapons establishment which has seen our work with this customer increase threefold 
in less than two years our work with awe has developed well beyond our traditional asbestos offering and we now 
offer a number of additional services we have also extended the regional prime contracts relationship for a further 
six years which is a fantastic success for the group  silverdell plc

chief executive’s statement continued 
 
operational review continued 
consulting defence revenues represented 9 2010 11 of the total although this represents a slight increase in 
absolute terms a significant defence customer during the year has been awe with whom we have successfully 
developed new consulting opportunities out of the longstanding relationship with the customer 
 
private sector 
power generation utilities and industrial 
power generation utilities and industrial customers totalled 27 of remediation segment revenues in 2011 2010 
29 we have leveraged our strong relationship with magnox to win a share of a £304m framework contract for 
asbestos removal deplanting and decommissioning at their first generation nuclear power stations which will serve 
to replace current work at the chapelcross site as it scales down in 2013  
in addition to the magnox framework contract win we have won a nationwide scaffolding framework contract with 
national grid which will provide the basis for increased penetration in this attractive sector we have also completed 
thermal insulation works on a major newbuild power station in south wales during the year and whilst the final 
account is still under negotiation management remains confident of a successful outcome in our consulting 
business power generation utilities and industrial customers rose to 18 201010 of total revenues we 
acquired a h allen in april 2011 which has a longstanding framework contract with a large water utility in the 
north east more importantly however we have won a significant amount of new business from remediation 
customers in this sector such as national grid and magnox 
construction 
construction’s share of total remediation revenues fell in 2011 to 7 201015 hard hit by the economic 
downturn there has been an absence of property development opportunities especially outside london and the south 
east the outlook for the construction sector remains poor with industry forecasts anticipating no upturn before 
2014   
consulting’s construction share of total revenues also fell to 1 2010 5 
retail commercial and rail 
this segment comprised 21 201018 of remediation revenues and 43 of consulting revenues 2010 33  
as anticipated we have seen a number of retail refurbishment projects being undertaken this year and we have 
worked for a number of major high street brands as they have sought to refresh their stores after a twoyear period of 
underinvestment during the year we also won a national framework with crawfords a leading loss adjuster to 
provide insurancerelated remediation works and this relationship is responsible for the majority of the increase in this 
work we operate a nationwide network that offers a 247 emergency callout to both residential and commercial 
properties and combine this responsiveness with a high quality service under a demanding service level agreement  
during the year we completed works under a crossrail contract in central london with this client also providing 
work for the consulting division 
the bulk of the consulting work in this segment is the provision of survey and management services to a nationwide 
broadcaster we continue to provide consulting services to a number of major insurance companies throughout the 
uk and trade strongly with many national well established retailers including opticians chemists supermarkets and 
banks the acquisition of rds will increase activity in this segment in the future thanks to its particular focus on the 
retail high street pubs and clubs

peabody  
making london a city of opportunity for all 
project  asbestos risk management and enabling works 
people  providing peace of mind to a diverse community 
business  working in partnership 
founded in 1862 by american banker diplomat and philanthropist george peabody the peabody group is london’s 
longest standing affordable housing provider and social entrepreneur its mission is to make london a city of 
opportunity for all by ensuring that as many people as possible have a good home a real sense of purpose and a 
strong feeling of belonging   
 
peabody defines “a good home” as a place that is safe warm clean light well maintained and evokes personal 
pride with safety first on their list of priorities and a portfolio of more than 20000 properties owned and managed 
across the capital for peabody the assessment and control of any risk to health that might be posed to their 50000 
residents through exposure to asbestos is paramount 
 
peabody’s relationship with silverdell plc’s consulting division redhills began in 2007 specialist in asbestos risk 
management redhills was appointed to assist peabody ensure its compliance with the recently introduced ‘duty to 
manage‘ legislation that arose from the implementation of regulation 4 of the control of asbestos regulations 2006 
 
redhills first task was to undertake an extensive programme of asbestos surveys which enabled peabody to formulate 
its corporate asbestos management plan and create an accurate register of asbestos risk the asbestos management 
plan details the strategy and processes peabody uses to safeguard its residents contractors and those in the wider 
community from risk of exposure to airborne asbestos fibres originating from its properties the asbestos register 
details the location and nature of current materials which are reinspected annually and updated to record any asbestos 
abatement works that have been undertaken     
 
in 2009 recognising the specific challenges arising from meeting the diverse needs of peabody’s residents  their 
languages and cultures the elderly and infirm individuals at high risk those with disabilities and young families  
redhills established a specialist housing team 
  
commenting on the benefits that redhills’ housing team have brought to the relationship gary jacobs building 
services asbestos coordinator at peabody said  
 
“having worked with redhills for over three years i have been consistently pleased by their honesty integrity and 
professional approach   
 
“redhills distinct advantage over other consultants is their dedicated and highly motivated housing team that 
understands the issues and problems faced by a social landlord and its tenants  their ability to meet our exacting 
kpi’s key performance indicators on a regular basis is testament to their customer focus   
 
“the word ‘partnering’ is often banded about but rarely understood  for me the relationship between peabody and 
redhills is what partnering is all about – an open and honest working relationship where trust is engendered in both 
parties” 
 
matt griggs managing director of redhills added 
“our specialist housing team is a practical example of how customer focus can bring real dividends to a relationship 
care is no soft virtue it’s a pragmatic means to deliver customer value” 
  silverdell plc

case studies continued 
 
since forming its specialist housing team redhills’ working partnership with peabody has developed to the extent 
that it now acts as a key consultant and stakeholder in all facets of peabody’s asbestos risk management   
 
 
delivering safety and efficiency in nuclear decommissioning 
 
project removing asbestos containing materials from firstgeneration nuclear reactor sites  
 
people ensuring peace of mind and a clean environment 
 
business asbestos remediation thermal insulation and scaffolding access  
 
 
kitsons’ relationship with the uk nuclear power industry began more than 20 years ago when we worked on the 
decommissioning of the berkeley reactor site on behalf of nuclear electric formerly cegb  
 
further asbestos removal contracts followed in the decommissioning of the ‘first generation’ reactors at trawsfynydd 
sizewell bradwell and hinkley point a in 2007 kitsons was awarded the contract to remove 3300 tons of asbestos 
containing materials acms from the chapelcross reactor site by magnox limited the site licensing company of the 
uk’s nuclear decommissioning agency nda 
 
the chapelcross contract was at the time the largest single asbestos removal project ever awarded in europe it 
differed from those that preceded it by being the first to be operated on an ‘open book target cost‘ basis in which the 
kitsons and magnox site teams became fully integrated to jointly plan and schedule the works in the delivery 
programme the objective of this transparent collaborative approach was to maximise efficiencies in the project 
programme and deliver real cost savings to the nda and the uk taxpayer  
 
the chapelcross project involved two phases that commenced with the design mechanical strengthening and erection 
of scaffold structures wrapped in a proprietary sheeting to completely contain the heat exchangers and provide a 
weather barrier this was followed by the removal and disposal of the asbestos containing and asbestos free thermal 
insulation present in the heat exchangers gas ducts pump houses pipework condensers and turbines on the site  
 
kitsons working directly for magnox in compliance with the uk health and safety legislation in two of the most 
highly regulated sectors of nuclear and asbestos creates safe containment structures around the areas to be stripped 
and then completes the bulk strip and fine clean of the site before conducting the safe disposal of the removed 
materials the project utilises kitsons asbestos removal thermal insulation and scaffolding capabilities 
 
commenced in 2007 the chapelcross project is on course for completion in 2012 such has been the success of the 
‘open book target cost’ approach that it has been instrumental in kitsons winning in a joint venture with its 
demolition and deplanting partner eds a share of a further £304m framework agreement with magnox the 10year 
agreement covers the removal of remaining acms from the ten first generation nuclear reactor sites operated by 
magnox 
 
commenting on the value of the ‘open book’ approach and the benefits of framework agreements andy watson 
kitsons managing director said 
 
“openness is a value shared throughout the silverdell group it helps us to develop trusted enduring relationships 
with our customers as we have here with magnox the collaboration that results generates a productive approach to 
joint planning and problem solving that ensures that project delivery is optimised”  
 
 
  silverdell plc  
 
 
20 
 
case studies continued 
 “from our customers’ standpoint this drives efficiencies avoids unnecessary delay and releases real cost savings in 
the project delivery framework agreements allow customers such as magnox to retain the learning with a buy once 
and use again approach certain of the capabilities and skills of their service partners benefiting from the supply 
chain and process improvements they have created with them over time” 
 
ensuring the safety of people at heathrow airport 
 
project the old control tower london heathrow airport 
 
people the passengers airport workers and public at the world’s busiest international airport 
 
business asbestos removal and remediation 
 
baa’s london heathrow is one of the busiest airports in the world with more than 186000 passengers passing through it every 
day and a place of work for some 76000 people as capacity demands have grown baa has sought to expand the airport’s 
facilities but with finite space available the operator is pressed to redevelop old facilities along with creating new 
 
in april 2007 in anticipation of the opening of the new terminal 5 and the changing demands of the airport baa moved the air 
traffic control facilities that oversee up to 480000 aircraft movements a year to a new tower immediately baa set about 
redeveloping the 50year old former control tower and office complex sited in the heart of the airport’s busy central area  
 
silverdell uk first became involved in the works in 2011 when appointed by baa’s main contractor mansell construction 
services to undertake a small project to remove various known nonnotifiable and notifiable asbestos bearing materials from three 
floors of the south and west wings of the old control tower buildings 
 
during the programmed asbestos removal works in the south wing silverdell discovered additional previously unidentified 
asbestos materials that required immediate action baa has a firm ‘sustainability commitment’ to ensure that heathrow is “a safe 
healthy and secure airport for staff and passengers” and when notified of silverdell’s discoveries the baa project team mansell 
and silverdell immediately set about developing a swift and safe plan of action to reduce their effect on the ensuing demolition 
works       
  
together with mansell and baa’s asbestos consultants wsp silverdell first undertook a full visual survey of the south wing to 
identify areas of concern and then assisted wsp to complete a full demolition survey without disturbance to the asbestos the 
surveys complete mansell with silverdells assistance led the project to isolate the electrical and mechanical connections needed to 
enable the safe completion of the planned asbestos removal and demolition works 
 
with the site prepared silverdell was then contracted to remove and dispose of the asbestosbearing materials identified in the 
wsp survey the project required 1300 man days to complete and resulted in the removal of 1200m
3
 of asbestos bearing 
materials from the site in 33 waste containers  delivered and collected at night to conform to airport regulations concerning 
hazardous waste movements 
 
given the sensitive location of the project site and its proximity to the airport central area’s public transport hub the works were 
subject to rigorous health and safety audit on 25 occasions in the course of their completion silverdell’s project management and 
site personnel were consistently commended by the mansell and baa audit teams for the excellence with which the site 
workforce and waste product removal were managed  the completed works being assessed as to amongst the highest standards yet 
experienced at the airport 
 
silverdell uk has subsequently been approached by baa’s ‘major projects’ team to assist where possible in the planning and 
programming of the remaining works to the west wing and old control tower building 
 
 
“silverdell is as assertive of site health and safety as we are in mansell we set demanding standards for our projects and 
silverdell met them impeccably at every stage  
 
 “on all of our many site visits we found silverdell’s work zones to be very well organised and all credit must be given to the 
professional commitment and safety culture shown by everyone in their team  supervisors and operatives alike 
 
“as the project progressed so our confidence and that of our baa client grew we have chosen to recognise silverdell’s 
contribution to the heathrow old control tower project by making them our ‘supplier of the month’ for september 2011”

financial review 
group turnover increased by 5 to £597m 2010 £567m on the back of a particularly strong second half where we 
recorded £318m of revenue 2010 £288m in h2 as we won a number of new and significant framework contracts 
particularly in consulting the revenue from our acquisitions in the year was £09m 2010 £nil gross profit was 
increased to £163m 2010£147m and the gross margin percentage therefore increased by 15 percentage points 
ppts to 274 2010 259 the main driver of this improvement was the business mix changing during the year 
with consulting revenues now comprising 14 of the group revenues 2010 11 where consulting gross margins 
are more than double the gross margins earned by the remediation segment subject to any further changes in the 
composition of the group this accretive impact on margin will continue through 2012 as the full year impact of the 
two acquisitions takes effect 
administration costs increased to £130m 2010£116m at the beginning of the year we introduced a number of 
employment benefits to all our salaried staff including a money purchase pension scheme on an optout basis which 
has been introduced ahead of the government’s proposed deadline this will help us to continue to attract and retain 
the best people we have also invested in management training and development during the year and this has 
delivered improvements in our business win ratio in each of our brands operating profit increased by £04m to 
£36m 2010 £32m  
as a result of the two acquisitions related integration costs and the capital reduction exercise we incurred an 
additional £03m of nonrecurring costs in the year 2010£nil 
finance charges were £05m 2010£07m profit before tax improved by 15 to £30m 2010 £26m statutory 
profit before tax improved by 39 to £25m 2010 £18mthe tax charge for the year was £08m 2010 £11m 
the effective corporation tax rate is 32 201060 profit after tax was £21m 2010 £15m and adjusted 
earnings per share was up 56 on last year at 14 pence 2010 09 pence statutory profit after tax was £17m 
2010 £07m the directors intend to pay a maiden dividend in 2012  
net debt at 30 september 2011 was up by £10m at £53m 2010£43m with gearing at 22 2010 23 of this 
the working capital outflow amounted to £36m 2010 £20m outflow this arose as a result of the volume growth 
particularly during q4 2011 which resulted in trade receivables being £26m higher at 30 september 2011 than at the 
same point last year we also have included in receivables amounts recoverable under contracts of more than £2m 
which we expect to recover during the first half of 2012 after the yearend the group’s revolving credit facility was 
extended by £1m to £35m 
the order book is significantly higher than last year the addition of £20m to the order book in respect of the magnox 
10 year framework contract as well as the impact of strong q4 orders and acquisitions brings the order book total up 
to £107m 2010£62m of which £36m 2010£34m relates to the new financial year 
the group uses derivatives designed to protect it from the interest rate risk that arises in respect of its borrowings for 
the majority of which the group applied hedge accounting in accordance with ias 39 at 30 september 2011 a 
liability was held on the balance sheet of £01m 2010£01m in respect of these derivatives all assets liabilities 
including borrowings and cash flows in the year were denominated in sterling and accordingly the group did not 
have an exposure to currency risk and has no related hedging products a full discussion of the financial risks to 
which the group is exposed along with the definitions of its key performance indicators is included in the 
statements on key risks and mitigations on pages 23 and 24 and corporate governance and risk management on 
page 32 
we completed two acquisitions during the year both in the second half in april we purchased ah allen limited a 
consulting business based in the north east for around £09m assuming achievement of stretch earnout targets at 
the end of august 2011 we raised £23m net of costs from a share placing of 235 million shares the proceeds of 
which went towards the purchase of rds asbestos management consultants uk limited “rds” for a maximum 
consideration of £23m again assuming achievement of stretch earnout targets this acquisition also included 
issuing 555 million shares to the vendors of rds as part of the total consideration as a result the number of issued 
allotted and fully paid up shares increased to end the year at 1808m 2010 1517m

key risks and mitigations 
the identification assessment and management of risk is fundamental to the achievement of the group’s strategic 
objectives the principal risks to the business as determined by the board are set out below the board recognises 
that the nature and scope of the risks faced by the business can change and so periodically reviews the risks and the 
controls in place to mitigate them andor transfer them to third parties 
market related risk 
the group is exposed to the risk of the general macroeconomic environment as well as government spending 
priorities we monitor the forward order books to ensure that appropriate resources are allocated to fulfil orders and 
procure new work either from existing clients or new customers 
regulatory risks 
the group operates in a sector overseen by a number of environmental regulators as such the regulatory landscape 
is constantly changing increasing the risk of noncompliance and the resultant reputational damage that may arise 
we remain fully committed to our teams being appraised of any changes in the regulatory framework through an 
extensive training programme outlined above we are members of all the recognised trade associations in the sectors 
we operate in and in particular one of our senior executives is a past chairman of the asbestos remediation trade 
body arca 
contractual risk 
the group operates in a sector where fixedprice contracts are common and this may result in a loss arising from a 
failure to properly reflect the operational risks in the contract price and terms all significant contracts are reviewed 
by the executive directors and independent legal advisors and all reasonable efforts are made to consider the 
potential extent of the work involved and the consequent risk of increased cost to provide reasonable certainty that the 
group has the capacity and capability to meet the requirements of the contract 
acquisition effectiveness 
the group’s strategy acknowledges that specific acquisitions may be required to enhance the group’s capability in 
certain areas there is a risk that an acquisition will fail to meet its strategic financial or operational objectives the 
board has set key investment criteria that must be made by any acquisition target all appropriate due diligence will 
be performed and contractual protections sought from the vendor to safeguard the group’s interests the board will 
review the requirement to retain the target’s key personnel and detailed integration plans will be put in place for 
implementation postacquisition 
people risk 
our people are our greatest asset and provide the basis for our competitive advantage we will seek to ensure that our 
operatives are trained through the application of a comprehensive training strategy and a policy that offers sufficient 
remuneration and incentives to retain our best people consistent with the market rates recruitment processes are 
applied that are appropriate to the seniority of the position being filled and to minimise the risk of an unsuitable 
appointment 
financial risks 
interest rate risk 
the group finances its operations through a mix of equity and debt funding all borrowings are denominated in 
sterling predominantly at variable rates of interest accordingly the group has hedged a proportion of its interest 
costs through an interest rate swap as mitigation against the risk of rising variable rates the board reviews the 
appropriateness of this policy from time to time taking into consideration expectations for future interest rates and the 
underlying level of borrowings 
 
credit including counterparty risk 
credit risk arises from the risk of having credit exposures to customers including outstanding receivables and 
retentions the group monitors the credit ratings of all customers with which it has or may have significant credit 
balances and takes any appropriate action it considers necessary including obtaining guarantees and ensuring that no 
single customer failure would present a significant risk to the achievement of the group’s strategic objectives  
  silverdell plc  
 
 
24 
 
key risks and mitigations continued 
counterparty risk arises from holding cash and cash equivalents with financial institutions the group controls this 
risk by ensuring that it enters into relationships only with highly creditrated financial institutions 
liquidity risk 
liquidity risk is the risk that the group does not have sufficient cash resources to meet its commitments whether 
short or long term the group has a mixture of borrowing facilities such as an overdraft to provide shortterm 
flexibility as well as a threeyear longterm facility arrangement the group prepares a rolling 13week cash flow 
forecast which is updated every two weeks which is reviewed by both management and the board to consider whether 
the group’s cash resources are sufficient 
covenant risk 
the group must comply with a number of financial covenants as the conditions of its banking facility the group 
monitors compliance with its covenants on an actual and forecast basis at each board meeting 
treasury risk 
treasury risk includes the risk of unauthorised or unsuitable transactions the group operates under a strict mandate 
in respect of its cash disbursements and all financial derivative contracts must be reviewed and approved by the 
board the group does not use derivative financial instruments for speculative purposes all new bank accounts or 
facilities and all new relationships with financial institutions must be approved by the board 
the group does not have an exposure to foreign currency risk 
 
health and safety 
our employees operate on construction sites and risk exposure to asbestos and other hazardous materials as such 
there is a significant threat to personal safety health and safety is the board and management’s highest priority we 
monitor and manage our safety processes and ensure that policies are reviewed and communicated at all levels all 
staff are of the highest industry standard through our internal training consulting safe the company also takes out 
appropriate insurance policies 
 
key performance indicators kpis 
the board monitors the performance of the group by regular reference to a small number of kpis which are 
 adjusted ebitda this is earnings before amortisation and impairment costs in respect of

statements  none of these is expected to have a significant impact on the group’s financial statements with 
the exception of ifrs 9 financial instruments which could change the presentation and classification of 
financial assets and liabilities the group does not plan to adopt this standard early and the extent of the 
impact has not yet been determined 
 
32 accounting policies  
basis of accounting 
the consolidated financial information has been prepared in accordance with ifrss adopted by the european 
union and therefore the group financial statements comply with article 4 of the eu ias regulation 
the consolidated financial information has been prepared on the historical cost basis except for the revaluation 
of certain financial instruments measured at fair value the principal accounting policies adopted are set out 
below 
basis of consolidation 
the consolidated financial statements incorporate the financial statements of the company and entities 
controlled by the company its subsidiaries made up to 30 september each year control is achieved where 
the company has the power to govern the financial and operating policies of an investee entity so as to obtain 
benefits from its activities 
the results of subsidiaries acquired or disposed of during the year are included in the consolidated income 
statement from the effective date of acquisition or up to the effective date of disposal as appropriate 
where necessary adjustments are made to the financial statements of subsidiaries to bring the accounting 
policies used in line with those used by the group 
all intragroup transactions balances income and expenses are eliminated on consolidation

business combinations  
the acquisition of subsidiaries is accounted for using the purchase method the cost of the acquisition is 
measured at the aggregate of the fair values at the date of exchange of assets given liabilities incurred or 
assumed and equity instruments issued by the group in exchange for control of the acquire the acquiree’s 
identifiable assets liabilities and contingent liabilities that meet the conditions for recognition under ifrs 3 
are recognised at their fair value at the acquisition date 
goodwill arising on acquisition is recognised as an asset and initially measured at cost being the excess of the 
cost of the business combination over the group’s interest in the net fair value of the identifiable assets 
liabilities and contingent liabilities recognised if after reassessment the group’s interest in the net fair value 
of the acquiree’s identifiable assets liabilities and contingent liabilities exceeds the cost of the business 
combination the excess is recognised immediately in profit or loss 
separately identifiable intangible assets are recognised on acquisition where appropriate and amortised over 
their useful economic life 
goodwill 
goodwill arising on consolidation represents the excess of the cost of acquisition over the group’s interest in 
the fair value of the identifiable assets and liabilities of a subsidiary at the date of acquisition goodwill is 
initially recognised as an asset at cost and is subsequently measured at cost less any accumulated impairment 
losses goodwill which is recognised as an asset is reviewed for impairment at least annually any impairment 
is recognised immediately in profit or loss 
for the purpose of impairment testing goodwill is allocated to each of the group’s cashgenerating units 
expected to benefit from the synergies of the combination cashgenerating units to which goodwill has been 
allocated are tested for impairment annually or more frequently when there is an indication that the unit may 
be impaired if the recoverable amount of the cashgenerating unit is less than the carrying amount of the unit 
the impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the unit and 
then to the other assets of the unit prorata on the basis of the carrying amount of each asset in the unit an 
impairment loss recognised for goodwill is not reversed in a subsequent period 
revenue recognition 
revenue is measured at the fair value of the consideration received or receivable and represents amounts 
receivable for services provided in the normal course of business net of discounts vat and other salesrelated 
taxes 
profit is recognised on longterm contracts if the final outcome can be assessed with reasonable certainty by 
including in the income statement revenue and related costs as contract activity progresses revenue is 
calculated by reference to the value of work performed to date as a proportion of total contract value 
leasing 
leases are classified as finance leases whenever the terms of the lease transfer substantially all the risks and 
rewards of ownership to the lessee all other leases are classified as operating leases 
assets held under finance leases are recognised as assets of the group at their fair value or if lower at the 
present value of the minimum lease payments each determined at the inception of the lease  
the corresponding liability to the lessor is included in the balance sheet as a finance lease obligation lease 
payments are apportioned between finance charges and reduction of the lease obligation so as to achieve a 
constant rate of interest on the remaining balance of the liability finance charges are charged directly against 
income 
rentals payable under operating leases are charged to income on a straightline basis over the term of the 
relevant lease 
benefits received and receivable as an incentive to enter into an operating lease are also spread on a straight
line basis over the lease term

32 accounting policies continued 
borrowing costs 
borrowing costs are recognised in profit or loss in the period in which they are incurred 
retirement benefit costs  
payments to defined contribution retirement benefit schemes are charged as an expense as they fall due  
taxation 
the tax expense represents the sum of the tax currently payable and the movements in deferred tax 
the tax currently payable is based on taxable profit for the year taxable profit differs from net profit as 
reported in the income statement because it excludes items of income or expense that are taxable or deductible 
in other years and it further excludes items that are never taxable or deductible the group’s liability for 
current tax is calculated using tax rates that have been enacted or substantively enacted by the balance sheet 
date 
deferred tax is the tax expected to be payable or recoverable on differences between the carrying amounts of 
assets and liabilities in the financial statements and the corresponding tax bases used in the computation of 
taxable profit and is accounted for using the balance sheet liability method deferred tax liabilities are 
generally recognised for all taxable temporary differences and deferred tax assets are recognised to the extent 
that it is probable that taxable profits will be available against which deductible temporary differences can be 
utilised such assets and liabilities are not recognised if the temporary difference arises from the initial 
recognition of goodwill or from the initial recognition other than in a business combination of other assets 
and liabilities in a transaction that affects neither the tax profit nor the accounting profit 
deferred tax liabilities are recognised for taxable temporary differences arising on investments in subsidiaries 
except where the group is able to control the reversal of the temporary difference and it is probable that the 
temporary difference will not reverse in the foreseeable future 
the carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced to the extent that 
it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be 
recovered 
deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or 
the asset is realised deferred tax is charged or credited in the income statement except when it relates to items 
charged or credited to other comprehensive income in which case the deferred tax is also dealt with in other 
comprehensive income 
deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets 
against current tax liabilities and when they relate to income taxes levied by the same taxation authority and 
the group intends to settle its current tax assets and liabilities on a net basis 
property plant and equipment 
property plant and equipment is stated at cost less accumulated depreciation and any recognised impairment 
loss 
depreciation is charged so as to write off the cost or valuation of assets other than land and assets under 
construction over their estimated useful lives on the following bases 
freehold property 4 on cost 
leasehold property 10 on cost 
plant and machinery 10 on cost 
office equipment 16625 on cost 
motor vehicles 25 on reducing balance 
assets held under finance leases are depreciated over their expected useful lives on the same basis as owned 
assets or where shorter over the term of the relevant lease 
the gain or loss arising on the disposal or retirement of an asset is determined as the difference between the 
sales proceeds and the carrying amount of the asset and is recognised in income  42 
 
32 accounting policies continued 
impairment of tangible and intangible assets excluding goodwill 
at each balance sheet date the group reviews the carrying amounts of its tangible and intangible assets to 
determine whether there is any indication that those assets have suffered an impairment loss if any such 
indication exists the recoverable amount of the asset is estimated in order to determine the extent of the 
impairment loss if any where the asset does not generate cash flows that are independent from other assets 
the group estimates the recoverable amount of the cashgenerating unit to which the asset belongs 
recoverable amount is the higher of fair value less costs to sell and value in use in assessing value in use the 
estimated future cash flows are discounted to their present value using a pretax discount rate that reflects 
current market assessments of the time value of money and the risks specific to the asset for which the 
estimates of future cash flows have not been adjusted 
if the recoverable amount of an asset or cashgenerating unit is estimated to be less than its carrying amount 
the carrying amount of the asset cashgenerating unit is reduced to its recoverable amount an impairment 
loss is recognised as an expense immediately where an impairment loss subsequently reverses the carrying 
amount of the asset cashgenerating unit is increased to the revised estimate of its recoverable amount but so 
that the increased carrying amount does not exceed the carrying amount that would have been determined had 
no impairment loss been recognised for the asset cashgenerating unit in prior years a reversal of an 
impairment loss is recognised as income immediately  
inventories and work in progress 
inventories are stated at the lower of cost and net realisable value cost comprises direct materials and where 
applicable direct labour costs and those overheads that have been incurred in bringing the inventories to their 
present location and condition cost is calculated using the weighted average method net realisable value 
represents the estimated selling price less all estimated costs of completion and costs to be incurred in 
marketing selling and distribution 
work in progress on service contracts is stated at cost plus where the outcome can be assessed with reasonable 
certainty estimated profits attributable to the stage of completion less provision for any expected losses and 
progress payments received on account  amounts recoverable on long term service contracts which are 
included in trade and other receivables are stated at the net sales value of the work done less progress 
payments received on account excess progress payments are included on trade and other payables 
cumulative costs incurred less amounts transferred to cost of sales less provision for contingencies and 
expected future losses on service contracts are included as longterm service contract balances in inventories 
financial instruments 
financial assets and financial liabilities are recognised in the group’s balance sheet when the group becomes a 
party to the contractual provisions of the instrument  
financial instruments are classified into the following categories financial assets at fair value through profit 
and loss “fvtpl” held for trading ‘loans and receivables’ at amortised cost financial liabilities  derivatives 
designated as cash flow hedges and financial liabilities at amortised cost 
the classification depends on the nature and purpose of the financial instruments  
trade receivables 
trade receivables are measured at initial recognition at fair value appropriate allowances for estimated 
irrecoverable amounts are recognised in profit or loss when there is objective evidence that the asset is 
impaired  43 
 
32 accounting policies continued 
cash and cash equivalents 
cash and cash equivalents comprise cash on hand and demand deposits and other shortterm highly liquid 
investments that are readily convertible to a known amount of cash and are subject to an insignificant risk of 
changes in value 
financial liabilities and equity 
financial liabilities and equity instruments are classified according to the substance of the contractual 
arrangements entered into an equity instrument is any contract that evidences a residual interest in the assets 
of the group after deducting all of its liabilities 
bank borrowings 
interestbearing bank loans and overdrafts are recorded at the proceeds received net of direct issue costs 
finance charges including premiums payable on settlement or redemption and direct issue costs are accounted 
for on an accrual basis in profit or loss using the effective interest rate method and are added to the carrying 
amount of the instrument to the extent that they are not settled in the period in which they arise 
trade payables 
trade payables are initially measured at fair value 
derivative financial instruments and hedge accounting 
the group’s activities expose it primarily to the financial risk of changes in interest rates the group uses 
interest rate swap contracts to hedge this exposure the group does not use derivative financial instruments for 
speculative purposes 
the use of financial derivatives is governed by the group’s policies approved by the board of directors which 
provide written principles on the use of financial derivatives   
changes in the fair value of derivative financial instruments that are designated and effective as hedges of 
future cash flows are recognised in other comprehensive income and the ineffective portion is recognised 
immediately in the income statement if the cash flow hedge of a firm commitment or forecasted transaction 
results in the recognition of an asset or a liability then at the time the asset or liability is recognised the 
associated gains or losses on the derivative that had previously been recognised in other comprehensive income 
are included in the initial measurement of the asset or liability for hedges that do not result in the recognition 
of an asset or a liability amounts deferred in other comprehensive income are recognised in the income 
statement in the same period in which the hedged item affects net profit or loss 
changes in the fair value of derivative financial instruments that do not qualify for hedge accounting are 
classified as fvtpl held for trading and the gains and losses are recognised in the income statement as they 
arise these are classified as held for trading as they have not been hedge accounted and have not been 
“designated” as fvtpl 
hedge accounting is discontinued when the hedging instrument expires or is sold terminated or exercised or 
no longer qualifies for hedge accounting at that time any cumulative gain or loss on the hedging instrument 
recognised in other comprehensive income is retained there until the forecasted transaction occurs if a hedged 
transaction is no longer expected to occur the net cumulative gain or loss recognised in other comprehensive 
income is transferred to the income statement for the period 
investments 
investments in subsidiaries are stated at cost less provision for any impairment 
provisions 
provisions are recognised when the group has a present obligation as a result of a past event and it is probable 
that the group will be required to settle that obligation provisions are measured at the directors’ best estimate 
of the expenditure required to settle the obligation at the balance sheet date and are discounted to present value 
where the effect is material

32 accounting policies continued 
 
sharebased payments 
the group issues equitysettled sharebased payments to certain employees equitysettled sharebased 
payments are measured at fair value excluding the effect of non marketbased vesting conditions at the date 
of grant the fair value determined at the grant date of the equitysettled sharebased payments is expensed on 
a straightline basis over the vesting period and is recognised as an employee expense with a corresponding 
increase in equity based on the group’s estimate of shares that will eventually vest and adjusted for the effect 
of non marketbased vesting conditions 
fair value is measured by use of the blackscholes model or the binomial method as appropriate the expected 
life used in the model has been adjusted based on management’s best estimate for the effects of non
transferability exercise restrictions and behavioural considerations 
intangible assets 
customer relationships 
customer relationships are measured as the present value of cash flows attributable to the relationship after 
deduction of appropriate contributory assets charged  the relationship is amortised over its expected useful 
life typically three years 
order book 
order book is the value of confirmed orders on the date of acquisition after appropriate costs have been 
deducted  the order book is amortised over the period in which it is expected to unwind 
4  critical accounting judgements and key sources of estimation uncertainty  
the preparation of consolidated financial statements in conformity with ifrs requires management to make 
judgements estimates and assumptions about the carrying amount of assets and liabilities and the amount of 
income and revenue recognised in the period  actual results may differ from these estimates 
the key assumptions concerning the future and other key sources of estimation uncertainty at the balance 
sheet date that have a significant risk of causing a material adjustment to the carrying amounts of assets and 
liabilities within the next financial year are discussed below   
revenue and profitmargin recognition 
the group’s revenue recognition turnover and long term contracts policies are set out in the notes above  
management exercises judgement to estimate the total expected contract costs and determine the percentage of 
completion in order to recognise the appropriate revenue and profit in the period  the assessment of 
profitability and recognition is assessed on an ongoing basis which ensures adequate controls are in place that 
appropriate amounts are calculated 
recognition and measurement of intangible assets under ifrs 3 ‘business combinations’ 
in order to determine the value of the separately identifiable intangible assets on the acquisition of a business 
combination management are required to make estimates on secured customer contracts other contracts and 
customer relationships and goodwill  the group engaged outside independent parties to perform these 
calculations and determine the fair value and estimated useful lives of these assets  45 
 
4 critical accounting judgements and key sources of estimation uncertainty continued 
impairment of goodwill and other intangible assets 
there are a number of assumptions management have considered in performing impairment reviews of 
goodwill and intangible assets determining whether goodwill is impaired requires an estimation of the value 
in use of the cashgenerating units to which goodwill has been allocated the value in use calculation requires 
the directors to estimate the future cash flows expected to arise from the cashgenerating unit and a suitable 
discount rate in order to calculate present value  note 12 details the assumptions that have been applied for 
goodwill 
5  segmental information 
the group has two reportable segments as described below which are the group’s strategic divisions  the 
strategic divisions offer different services and are managed separately because they have some differences in 
their risks and operating models for each of the strategic divisions the group’s ceo the chief operating 
decision maker reviews internal management reports on at least a monthly basis  the following summary 
describes the operations in each of the group’s reportable segments 
remediation – provides services related to the direct remediation and removal of environmental risks the     
principal two group companies in this segment being silverdell uk and kitsons 
consulting – provides environmental survey monitoring and project management services the principal          
company in this segment being redhill analysts and its subsidiaries rds and a h allen 
information regarding the results of each reportable segment is included below  performance is measured 
based on segment profit before tax as included in the internal management reports that are reviewed by the 
group’s ceo  segment profit is used to measure performance as management believes such information is the 
most relevant in evaluating the results of certain segments relative to other entities that operate within these 
industries

the main rate of corporation tax from 28 to 27 from 1 april 2011 an additional 1 reduction reducing the 
rate to 26 also effective from 1 april 2011 was announced by the uk government in the budget on 23 
march 2011 and substantively enacted on 29 march 2011 these changes to tax rates are not expected to have 
a material effect on the group 
the group’s planned level of capital investment is expected to remain at similar levels  therefore it expects 
to be able to claim allowances in excess of depreciation in future years at a similar level to the current year  51

weighted average number of ordinary shares during the year determined in accordance with the provisions of 
ias 33 “earnings per share” 
diluted earnings per share is calculated by adjusting the weighted average number of ordinary shares in issue 
on the assumption of conversion of all dilutive potential ordinary shares  
adjusted basic earnings per share is calculated by dividing the earnings attributed to ordinary shareholders 
before intangible assets amortisation sharebased payment charges nonrecurring expenses and finance

the group tests goodwill annually for impairment or more frequently if there are indications that goodwill 
might be impaired  goodwill is allocated for impairment testing to cash generating units cgu which reflects 
how it is monitored for internal management purposes  the recoverable amounts of the cgus are determined 
from value in use calculations value in use is calculated using pretax cashflow projections based on the 
financial budgets and business plans covering a three year period which take into account historical trends and 
market conditions which have been approved by the board the key assumptions for the value in use 
calculations are those regarding the discount rates and growth rates for the period  management estimates 
discount rates using pretax rates that reflect current market assessments of the time value of money and the 
risks specific to the cgus equivalent to a real pre tax discount rate which average 12 2010 12  the 
growth rates are based on industry growth forecasts and longterm growth in gross domestic product  
the group prepares cash flow forecasts derived from the most recent financial budgets approved by 
management for the next three years and extrapolates cash flows for the following years based on an estimated 
annual growth rate of 1  the rates do not exceed the average longterm growth rate for the relevant markets  
the rates used to discount the cash flows in both 2011 and 2010 for all cgus have been based on the group’s 
weighted average cost of capital because the cgus do not have significantly differing risk profiles   
the group’s impairment review is sensitive to changes in the key assumptions used the major assumptions 
that result in significant sensitivities are the revenue growth and the discount rate given the group’s 
sensitivity analysis a reasonably possible change in a single assumption will not result in further impairments  54

c  credit risk 
the group’s principal financial assets are cash and cash equivalents and trade and other receivables which 
represent the group’s maximum exposure to credit risk in relation to financial assets 
the group’s credit risk is primarily attributable to its trade and other receivables  the amounts presented in 
the consolidated balance sheet are net of allowances for doubtful receivables estimated by the group’s 
management based on prior experience and their assessment of the current economic environment 
credit risk refers to the risk that a counterparty will default on its contractual obligations resulting in financial 
loss to the group the group has adopted a policy of only dealing with creditworthy counterparties as a means 
of mitigating the risk of financial loss from defaults  
the carrying amount of financial assets recorded in the financial statements which is net of impairment losses 
represents the group’s maximum exposure to credit risk   
the group’s exposure and the credit ratings of its counterparties are continuously monitored and the aggregate 
value of transactions concluded is spread amongst approved financial institutions   62 
 
22 financial instruments continued 
c  credit risk continued 
trade receivables 
trade receivables consist of a large number of customers spread across diverse areas within the uk and the 
group’s exposure to credit risk is influenced mainly by the individual characteristics of each customer the 
demographics of the group’s customer base including default risk of the industry and country in which the 
customers operate has less of an influence on credit risk 
 
the directors consider that the carrying amount of trade and other receivables which are noninterest bearing 
approximates to their fair value   
the group does not have any significant credit risk exposure to any single counterparty or any group of 
counterparties having similar characteristics the group defines counterparties as having similar characteristics 
if they are related entities   
 
before accepting any new customer the group runs credit checks to assess the potential customer’s credit 
quality  the group monitors exposure to individual clients and all customers are subject to standard terms of 
payment for each division which are on average 30 days 
the analysis of trade receivables in excess of 30 days old but not impaired is as follows

the group establishes an allowance for impairment that represents its estimate of incurred losses in respect of 
trade and other receivables and investments when there is objective evidence that the asset is impaired  the 
main components of this allowance are a specific loss component that relates to individually significant 
exposures and a collective loss component established for groups of similar assets in respect of losses that 
have been incurred but not yet identified  the collective loss allowance is determined by references to past 
default experience and historical data of payment statistics for similar financial assets

the creation and release of provisions for impaired receivables has been included in ‘administrative expenses’ 
in the income statement 
in determining the recoverability of a trade receivable the group considers any change in the credit quality of 
the trade receivable from the date credit was initially granted up to the reporting date the concentration of 
credit risk is limited due to the customer base being large and unrelated accordingly the directors believe that 
there is no further credit provision required in excess of the above amount 
d  liquidity risk 
liquidity risk is the risk that the group will not be able to meet its financial obligations as they fall due  
responsibility for liquidity risk management rests with the board of directors  the group manages liquidity 
risk by maintaining adequate reserves banking facilities and reserve borrowing facilities by continuously 
monitoring bank covenant compliance forecast and actual cash flows and matching the maturity profiles of 
financial assets and liabilities details of additional undrawn facilities that the group has at its disposal to 
further reduce liquidity risk are disclosed in note 20 
liquidity and interest risk tables 
the following tables detail the group’s expected maturity for its financial assets and liabilities the tables 
below have been drawn up based on the undiscounted contractual maturities of the financial assets and 
liabilities no material interest is expected to accrue on the interest bearing assets which represent cash 
deposits

e  interest rate risk 
interest rate risk is the risk that the value of a financial instrument or cash flows associated with the instrument 
will fluctuate due to changes in market interest rates  as the group has no significant interestbearing assets 
the group’s income and operating cash flows are substantially independent of changes in market interest rates 
the group is exposed to interest rate risk primarily though borrowing funds at floating interest rates  
borrowings issued at variable rates expose the group to cash flow interest rate risk  the group manages 
interest rate risk on borrowings by ensuring access to diverse funding and through monitoring interest rate 
movements with weekly reports   
interest rate risk is reviewed on a regular basis and if considered necessary a strategy to minimise any potential 
risk through interest rate swaps will be discussed and implemented   
based on the various scenarios the group manages its cash flow interest rate risk by using a combination of 
floatingtofixed interest rate swaps and an interest rate cap the interest rate swap has the economic effect of 
converting borrowings from floating rates to fixed rates  generally the group raises long term borrowings at 
floating rates and swaps them into fixed rates that are lower than those available if the group borrowed at fixed 
rates directly  under the interest rate swap the group agrees with other parties to exchange at specified 
intervals primarily quarterly the difference between fixed contract rates and floating rate instrument amounts 
calculated by reference to the agreed notional amounts the interest rate cap ensures that for the specified 
portion of borrowings floating rate interest will apply only up to a specified ceiling 
the group’s exposures to interest rates on financial assets and financial liabilities are detailed below   
interest rate sensitivity analysis 
if interest rates had been 100 basis points higher or lower and all other variables were held constant the 
group’s profit for the year would increase or decrease by £45000 2010 £61000 in respect to exposure to the 
group’s borrowings and cash and cash equivalents  for floating rate liabilities the analysis is prepared 
assuming the amount of the liability at the balance sheet date was outstanding for the whole period 
f  fair value of financial instruments 
the fair value of interest rate swaps is calculated at the present value of the estimated future cash flows 
the directors consider that the carrying amounts of financial assets and financial liabilities recorded at 
amortised cost in the financial statements approximate to their fair values due to the short maturity of the 
instruments or because they bear interest at rates approximate to the market    66

an analysis of the maturity of debt is given in note 22d   
the directors consider that the carrying amount of trade payables approximates to their fair value  
the group’s policy is to fix payment terms when agreeing the terms of each transaction  it is the group’s 
general policy to pay suppliers according to the agreed terms and conditions provided that the supplier has 
complied with those terms   
trade creditors and accruals principally comprise amounts outstanding for trade purchases and ongoing cost 
and they include retention amounts held over defect liability periods  the average credit period taken for trade 
purchases is 69 days 2010 45 days for the group  the group has financial risk management policies in 
place to ensure that all payables are paid within the credit timeframe 
there are no suppliers who represent more than 10 of the total balance of trade creditors in either 2011 or 
2010 
the group has financial risk management policies in place to ensure that all payables are paid within the credit 
timeframe therefore under the normal course of business the group is not charged interest on overdue 
payables  67

30  significant accounting policies 
the separate financial statements of the company have been prepared on the historical cost basis and under the going 
concern assumption the accounting policies are summarised below and have been applied consistently throughout 
the year and the preceding year the separate financial statements are presented as required by the companies act 
2006  as permitted by that act the separate financial statements have been prepared in accordance with united 
kingdom accounting standards 
taxation 
the tax currently payable is based on the taxable profit for the year taxable profit differs from net profit as reported 
in the income statement because it excludes items of income and expense se that are taxable or deductible in other 
years and it further excludes items which are never taxable or deductible the company’s liability for current tax is 
calculated using tax rates that have been enacted or substantively enacted at the balance sheet date  
deferred taxation is provided in full on all timing differences that result in an obligation at the balance sheet date to 
pay more tax or a right to pay less tax at a future date subject to the recoverability of deferred tax assets  deferred 
tax assets and liabilities are not discounted 
sharebased payments 
the company has applied the requirements of frs 20 sharebased payment  in accordance with the transitional 
provisions frs 20 has been applied to all grants of equity instruments after 7 november 2002 that had not vested as 
at 1 january 2005 
the company makes equity settled sharebased payments to the directors which are measured at fair value at the date 
of grant the fair value of share options issued with nonmarket vesting conditions has been calculated using the 
black scholes model  for all other share awards the fair value is determined by reference to the market value of the 
share at the date of grant  for all share schemes with nonmarket related vesting conditions the likelihood of vesting 
has been taken into account when determining the associated charge  vesting assumptions are reviewed during each 
reporting period to ensure they reflect current expectations 
the company also makes equity settled sharebased payments to certain employees of certain subsidiary 
undertakings  equity settled sharebased payments that are made to employees of the company’s subsidiaries are 
treated as increases in equity over the vesting period of the award with a corresponding increase in the company’s 
investments in subsidiaries based on an estimate of the number of shares that will eventually vest 
any payments received from subsidiaries are applied to reduce the related increases in investments in subsidiaries 
accounting for sharebased payments is the same as under ifrs 2 and details on the schemes and option pricing 
models relevant to the charge included in the company financial statements are set out in note 25 to the consolidated 
financial statements of the group for the year ended 30 september 2010
