           INTERIM RESULTS FOR THE SIX MONTHS ENDED 30 SEPTEMBER 2003

         IMPROVED PERFORMANCES ACROSS ALL BUSINESSES DRIVE PROFIT GROWTH

o   Profit on ordinary activities before goodwill amortisation, exceptional
    items and taxation - increased by 4.4 per cent to(pound)171 million
o   Licensed multi-utility operations - innovative rights issue and IDoK ahead
    of next review period
o   Business process outsourcing - segmental operating profit* increased by 41
    per cent to (pound)12 million
o   Infrastructure management - segmental operating profit* increased by 14 per
    cent to (pound)32 million
o   Telecommunications - turnover increased by 10 per cent to (pound)87 million
o   Interim dividend per ordinary share of 14.43 pence

* Segmental operating profit/loss is defined as the profit/loss on ordinary
activities before non-operating items, goodwill amortisation, exceptional items,
interest and taxation for a segment as shown in the segmental analysis by class
of business disclosed later in this document. This is a measure regularly
reviewed by management to assess segment performance.

Chief Executive John Roberts said:

"I'm pleased to report that improved performances across all of our businesses
have contributed to profit growth in the first half of the year. This maintains
our record of continuously improving profit throughout the current regulatory
period.

"During the period, the extent of the future investment demands for our licensed
multi-utility operations business became clearer, principally driven by European
Union directives. The funding requirements of our regulated businesses drove our
decision to raise (pound)1 billion from our shareholders, through an innovative
two-stage rights issue. The resolution approving the issue of new equity was
passed at our EGM with 98.2 per cent of votes cast in favour. 91.3 per cent of
the Initial A Shares were taken up and the balance was successfully placed in
the market at a premium.

"Recently we received Ofwat's draft decision on our Interim Determination of K
("IDoK") application, which recognises additional costs which were not predicted
by Ofwat when prices were set at the last periodic review. In its draft
determination, Ofwat proposed that United Utilities Water be allowed to increase
real prices by a further 3.7 per cent, to a total real increase of 8.2 per cent,
in 2004/05. Ofwat has also confirmed our concerns with regard to the value for
money on part of the capital programme dealing with unsatisfactory intermittent
discharges. As it's unlikely that this issue will be resolved by next week, when
Ofwat release their final IDoK determination, recognition of these costs will
probably be deferred until AMP4.

"Our support services businesses continue to make significant progress, with
operating profit from these businesses tripling since 2000. Vertex, our business
process outsourcing business, has had a particularly pleasing six months, having
seen a substantial increase in operating profit as the start-up costs associated
with our major public sector contracts with Westminster City Council and the
Department for Work and Pensions, have come to an end. Operating margins also
improved, to 6.8 per cent, having almost doubled in the last three years.

"In addition, Vertex has achieved some notable renewals and extensions of
contracts in the period. For example, it has signed a nine-year contract with
Powergen, which replaces its previous contract with TXU Europe, and has recently
agreed terms for an extended range of customer management services to Vodafone.

"United Utilities Contract Solutions has continued to grow operating profit. The
Scottish Water contract, which involves the management of the delivery of new
capital expenditure in Scotland, mainly to improve environmental standards,
commenced in the summer, and further confirms our position as the leading player
in the UK outsourced utility infrastructure market.

"Our telecommunications business, Your Communications, continues to be on track
to be a net cash contributor to the group on a post-tax basis this year. We've
had continued success in growing sales, which increased by 10 per cent compared
to the corresponding period last year, and reducing operating losses, which have
fallen as we've increased turnover and controlled operating costs."

Commenting on the outlook for United Utilities, John Roberts said:

"We expect that operating profits in our water business will benefit
significantly from an expected allowed real price increase of at least 8.2 per
cent next year. Our support services businesses are also set to grow, as they
benefit from recent contract wins and renewals with Scottish Water, Powergen and
Vodafone.

"The next year will also provide greater clarity for our water and electricity
businesses as we enter the final stages of the periodic review process. The
challenge for both regulators now is to meet the requirements of all
stakeholders. In particular they need to balance the desire for environmental
improvements with prices for customers which represent value for money.

"We welcome the increased transparency Ofwat has brought to the review process.
This has served to reduce regulatory uncertainty, which can only help to improve
the industry's access to capital markets over the longer term. In light of
Ofwat's recent announcements, we continue to expect that the water review will
provide acceptable returns for shareholders, with the potential for further
upside from regulatory outperformance."

In conclusion, the Chairman, Sir Richard Evans, said:

"I'm pleased that the business has moved forward significantly over the past six
months, by delivering on key strategic objectives. In line with our promise to
maintain dividends in real terms, the board has decided to increase the interim
dividend, after adjusting for the rights issue, by 2.6 per cent. The board is
also pleased that shareholders demonstrated their support for the group's
management and prospects, through their take-up of the rights issue."

DIVIDEND

Prior period dividends have been re-presented for comparative purposes to take
account of the bonus element of the first stage of the rights issue. For details
of the re-presented prior year non-GAAP measure and computation thereof, refer
to note 11 of the unaudited condensed consolidated financial information. The
factor applied to the prior period dividends is 0.9072, calculated using 576.0
pence per ordinary share, this being the closing price on 25 July 2003, the last
business day prior to the announcement of the rights issue.

The board has declared an interim dividend in respect of the six months ended 30
September 2003 of 14.43 pence per ordinary share, and 7.215 pence per A share.
This is an increase of 2.6 per cent on last year's re-presented interim dividend
of 14.06 pence. These dividends will be paid on 9 February 2004 to shareholders
on the register at the close of business on 19 December 2003. The ex-dividend
date for the interim dividend is 17 December 2003.

FINANCIAL PERFORMANCE

Turnover (including share of joint ventures) rose 12.0 per cent to
(pound)1,024.6 million, reflecting growth across all businesses.

Profit on ordinary activities before non-operating items, goodwill amortisation,
exceptional items, interest and tax (including share of joint ventures) rose 4.6
per cent to (pound)290.9 million compared with the same period in the previous
year. This increase primarily reflected improved operating profits in
infrastructure management, business process outsourcing and licensed
multi-utility operations, and reduced operating losses in telecommunications.

After a 5.0 per cent increase to (pound)119.9 million in net interest payable,
profit on ordinary activities before goodwill amortisation, exceptional items
and tax increased by 4.4 per cent to (pound)171.0 million. Interest charges
increased due to the higher level of borrowings to fund our capital expenditure
programme, mitigated by lower average borrowing costs.

Goodwill amortisation was (pound)4.3 million, compared with (pound)3.5 million
in the corresponding period last year. The increase principally reflects the
goodwill arising from the acquisition of 7C by Vertex in December 2002.

The group recorded a current tax credit of (pound)2.4 million during the period.
The deferred tax credit on ordinary activities was (pound)7.1 million, compared
with a charge of (pound)49.4 million in the corresponding period last year. This
credit is principally due to the increased discount applied to the gross
provision, reflecting the movement in gilt yields in the period.

Basic earnings per share increased by 35.1 per cent to 28.5p. Basic earnings per
share have been restated for all periods prior to the rights issue to reflect
the bonus element of the first stage of the rights issue.

Adjusted basic earnings per share have been restated for all periods prior to
the rights issue to reflect the full bonus element of the rights issue. The
adjustment factor is 0.8646, calculated using 531.5p per ordinary share, this
being the closing price on 26 August 2003, the date of approval of the rights
issue at the Extraordinary General Meeting.

Adjusted basic earnings per share increased by 48.9 per cent to 27.7p, largely
as a result of the reduction in the deferred tax charge. Excluding deferred tax,
adjusted basic earnings per share increased by 1.1 per cent to 26.6p.

Net debt at 30 September 2003 was (pound)3,228.0 million, a reduction of
(pound)145.9 million compared with 31 March 2003. This is after the receipt of
around (pound)500 million from the first stage of the rights issue, and also
reflects the earlier payment of the 2002/03 final dividend, totalling
(pound)178.2 million, which was brought forward from October to August.

Gearing, calculated as net debt divided by net debt plus equity shareholders'
funds, fell from 57.1 per cent, at 31 March 2003, to 50.9 per cent at 30
September 2003.

Since 31 March 2003 the group has issued (pound)373 million of various
long-dated bonds and there have also been time extensions on existing medium
term committed bank facilities of (pound)50 million. Cash and short term
investments at 30 September 2003 were (pound)967 million which, together with
net undrawn facilities of (pound)675 million and committed but undrawn term
funding of (pound)10 million, provides substantial pre-funding for the group's
capital investment programme.

OPERATING PERFORMANCE

LICENSED MULTI-UTILITY OPERATIONS

o  Turnover increased by 6.4 per cent to (pound)642.5 million
o  Segmental operating profit* increased by 1.3 per cent to (pound)254.9 million
o  Net operating assets of (pound)6,870.0 million

Turnover increased by 6.4 per cent to (pound)642.5 million, principally
reflecting an allowed real price increase of 4 per cent in our water and
wastewater charges.

Segmental operating profit* increased by 1.3 per cent to (pound)254.9 million
for the period. This was mainly as a result of the allowed real price increase
for United Utilities Water, partially offset by a number of factors, principally
higher operating costs and depreciation due to the expanding asset base
resulting from capital expenditure on quality related obligations.

In November, United Utilities received Ofwat's draft determination on its
Interim Determination of K ("IDoK") application, which was submitted earlier in
the year. In its draft determination Ofwat has issued a counter notice relating
to costs already incurred and forecast to be incurred on part of the capital
programme dealing with unsatisfactory intermittent discharges ("UIDs"), and has
stated that it wishes to consider further evidence on this programme before
arriving at a final conclusion.

Ofwat confirmed United Utilities' concerns regarding value for money with
respect to a proportion of the UID programme. In arriving at its draft
determination Ofwat eliminated the allowed expenditure for these projects, and
expects to substitute the costs of revised schemes as agreed by the company with
the Environment Agency and DEFRA. As it is unlikely that such revised schemes
will be agreed in a time frame to allow recovery of these costs in the prices
set from 1 April 2004, recognition of these costs will probably be deferred
until the price review, and recovered in prices from 1 April 2005.

Ofwat is due to announce its final determination on United Utilities' IDoK
application on 11 December 2003.

By 31 March 2004 the water regulator requires United Utilities to have delivered
around three-quarters of its 840 AMP3 capital enhancement outputs. The company
anticipates that it will still be ahead of its regulatory schedule at the end of
the financial year.

Capital investment in the period was (pound)473.2 million, the highest ever by
United Utilities during a six month period, of which (pound)409.0 million
related to water and wastewater and (pound)64.2 million to electricity
distribution. The company continues to expect capital expenditure in the full
year to be around (pound)1 billion.

Charlie Cornish has been appointed as Managing Director of United Utilities
Service Delivery, with effect from 12 January 2004. Mr Cornish, aged 43, is
currently Chief Operating Officer for Thames Water, responsible for service
delivery, including operations and capital programmes. Prior to working for
Thames he was Chief Executive of West of Scotland Water Authority.

INFRASTRUCTURE MANAGEMENT

o  Turnover increased by 18.1 per cent to(pound)207.2 million
o  Segmental operating profit* (including share of joint ventures) increased by
   14.3 per cent to(pound)32.0 million
o  Net operating assets of(pound)103.2 million

United Utilities Contract Solutions applies the core infrastructure management
skills of the licensed multi-utility businesses to growth markets, serving over
10 million people throughout the UK and overseas.

Operations management

Operations management develops and operates contracts in selected markets based
on the group's core infrastructure management skills. It has a focused approach
to pursuing opportunities with the objective of securing long-term relationships
and operational sources of income whilst limiting financial exposure.

During the period, Scottish Water Solutions was established. This is a joint
venture company consisting of United Utilities (in conjunction with Galliford
Try and Morgan Est), Stirling Water and Scottish Water.

Scottish Water Solutions will deliver the bulk of Scottish Water's four-year
(pound)1.8 billion capital investment programme, the funding for which will be
provided by Scottish Water. Martin Bradbury, previously the Asset Management
Director within United Utilities Service Delivery, has been seconded as Scottish
Water Solutions' Chief Operating Officer.

The key objectives of Scottish Water Solutions are to deliver Scottish Water's
capital programme on time, whilst making efficiencies both in terms of delivery
and whole life asset costs. A management team has already been established,
which now leads a workforce of over 400 employees, who have been seconded from
partners within the consortium. Having commenced operations in the summer, the
consortium is expecting to have delivered over (pound)200 million of the
programme by the end of this financial year.

In November, United Utilities, in partnership with the European Bank for
Reconstruction and Development ("EBRD"), increased its shareholdings in its
European concessions, subject to regulatory approval, by agreeing to buy
International Water's shareholdings in Sofijska Voda AD in Bulgaria, AS Tallinna
Vesi in Estonia and Przedsiebiorstwo Komunalne Aqua SA in Bielsko-Biala in
Poland.

Following the acquisition, the shareholdings will be held in a joint venture
company that is owned equally by United Utilities and the EBRD. This is the
first time that the EBRD has taken a substantial equity position alongside a
water utility, giving United Utilities a strong strategic partner in Europe, and
a platform for further growth.

The Welsh Water contract continues to perform well, both in terms of service
levels and costs. Glas Cymru has published its plans for the letting of the
contract post 31 March 2005 and United Utilities has made a pre-qualification
submission. Based on United Utilities' performance the company believes that it
is well placed to win further business with Glas Cymru.

Green energy

United Utilities is also developing a number of schemes, with a potential
capacity of up to 100MW, that capitalise on the group's presence as owner of
electricity, water and land assets in North West England.

Plans for the wind farm at Scout Moor, in Lancashire, which has a potential
capacity of up to 65MW, have now been lodged with the Department of Trade and
Industry, which decides on planning consents for all developments over 50MW in
England.

United Utilities is continuing to appraise and develop its offshore wind farm
opportunity at Scarweather Sands, which has a potential capacity of 90MW. The
public inquiry into this project started in November 2003.

Network services

United Utilities Networks is a national market leader in the rapidly developing
multi-utility metering and connections markets. The business provides gas,
water, electricity and telecommunications connections and metering to domestic,
commercial and industrial developers.

Due to an increasingly tough regulatory climate, and its relatively small scale,
United Utilities sold its private gas networks business, in October 2003, to
East Surrey Holdings plc for (pound)3.1 million.

The metering services contract with British Gas Trading continues in its
formative stages, as BGT and United Utilities align their business processes to
address the expected separation issues accompanying this innovative contract.
Activity levels in the second half and beyond should grow further as the
contract moves out of its mobilisation phase.

BUSINESS PROCESS OUTSOURCING

o  Turnover increased by 25.3 per cent to (pound)178.9 million
o  Segmental operating profit* increased by 40.7 per cent to (pound)12.1 million
o  Segmental operating profit* margin increased from 6.0 per cent to 6.8 per
   cent
o  Net operating assets of (pound)114.6 million

Vertex provides business process outsourcing services to utilities, local and
central government and the service segment of the private sector. Vertex
specialises in transforming front and back-office processes and the management
of customer relationships. This is particularly relevant to clients with large
customer bases, such as in the utility and public sectors, who require customer
management and transformational capability, and the associated cost savings,
when outsourcing their business processes.

Sales growth in the period was principally due to new contributions from public
sector contracts with the Department for Work and Pensions and Westminster City
Council, both of which commenced in the second half of the previous year.

Vertex's segmental operating profit* margin improved to 6.8 per cent from 6.0
per cent in the same period last year. This increase reflects the increasing
maturity of the external contract portfolio and the relatively low level of
contract mobilisation costs during the period.

In July Vertex signed a contract with Powergen, replacing Vertex's previous
contract with TXU Europe. It has an overall term of nine years and is subject to
review after four years. Vertex had been providing services to Powergen since
Powergen acquired TXU Europe's retail business in October 2002, and this
contract consolidates the relationship between the two companies. Prior to the
acquisition, Vertex had been providing services to TXU Europe under a 10-year
contract, which was signed in August 2002.

Vertex has recently agreed renewal terms for its contract to provide customer
management services with Vodafone. The new contract also expands the range of
services provided to Vodafone.

In addition Vertex has also signed a contract with Lloyds TSB to provide
customer management and IT related billing services for its home energy and
telephony offering, which was launched in the summer.

During the period Vertex has agreed terms with Orange to provide a range of
inbound customer management services. Under the terms of the new contract,
Vertex will provide customer services support for Orange pay-as-you-go customers
including customer registrations, phone code unlock assistance and phone credit
activation.

Capacity at Vertex's Indian contact centre, which was acquired from 7C in
December 2002, has increased from around 220, to nearly 900 employees. This
front and back-office capability is currently being utilised by a number of
Vertex's private sector clients.

In the period, just over half of Vertex's revenues were derived from contracts
renewed or secured in the last eighteen months, testament to the increasing
momentum of the business.

TELECOMMUNICATIONS

o Business turnover increased by 11.0 per cent to (pound)70.5 million o Turnover
increased by 9.6 per cent to (pound)86.9 million o Segmental operating loss*
reduced by 7.8 per cent to (pound)9.4 million o Net operating assets of
(pound)199.5 million

Your Communications offers voice, basic and advanced data communication services
to the public sector, and small and medium-sized corporate customers,
predominantly in the Midlands and North of England.

Business sales from voice and data services increased by 11.0 per cent to
(pound)70.5 million, and premium rate services increased by 3.8 per cent to
(pound)16.4 million. This reflects further progress in the changing of Your
Communications' sales mix to higher margin business customers.

Segmental operating losses fell by 7.8 per cent to (pound)9.4 million, due to
increased turnover and control of operating costs. Headcount has been reduced by
around a third since April 2001, as the network building phase of the business
has been completed.

Your Communications remains on track to be a net cash contributor to the group,
on a post-tax basis, in 2003/04.

NOTES

1. Basis of preparation
The results for the period ended 30 September 2003, which are unaudited, have
been prepared in accordance with accounting principles generally accepted in the
United Kingdom (UK GAAP) on the basis of accounting policies consistent with
those set out in the annual report to shareholders for the year ended 31 March
2003.

The financial information set out in this statement relating to the year ended
31 March 2003 does not constitute statutory accounts for that period. Full
audited accounts of United Utilities PLC in respect of that financial period
(which received an unqualified audit opinion and did not contain a statement
under either section 237(2) or (3) of the Companies Act 1985) have been
delivered to the Registrar of Companies.

2. Rights Issue
The 5 for 9 rights issue, structured so that the proceeds are received in two
stages, was approved at the Extraordinary General Meeting of shareholders on 26
August 2003. The first tranche of the proceeds, received during September 2003,
raised (pound)502.3 million (net of costs) from the issuing of 309,286,997 A
shares. The first dividend for which the initial A shares will rank is the
2003/04 interim dividend; the amount of this dividend is 50 per cent of that
paid on an ordinary share. The second tranche of proceeds will be received in
June 2005, reflecting the subscription for further A shares. All A shares will
then be consolidated and reclassified as ordinary shares on the basis of one
ordinary share for two A shares.

3. Goodwill and exceptional items

5. Earnings per share
Basic earnings per share and diluted earnings per share are calculated by
dividing profit for the period by the following weighted average number of
shares in issue:

                                                           Basic         Diluted
(i)   Period ended 30 September 2003               614.1 million   618.2 million
(ii)  Period ended 30 September 2002 (restated)    605.9 million   607.7 million
(iii) Year ended 31 March 2003 (restated)          606.0 million   607.7 million


For the purposes of calculating the weighted average number of shares used in
the earnings per share calculations, the A shares have been treated as part paid
ordinary shares, two A shares being equivalent to one ordinary share.

The difference between the weighted average number of shares used in the basic
and the diluted earnings per share calculations represents those ordinary shares
deemed to have been issued for no consideration on the conversion of all
potential dilutive ordinary shares in accordance with FRS 14 (Earnings per
Share).

The basic and diluted weighted average number of shares have been restated for
all periods prior to the rights issue to reflect the bonus element of the rights
issue as required by FRS14. The adjustment factor is based on the consideration
received from the first stage of the rights issue. The adjustment factor is
0.9176, calculated using 531.5p per ordinary share, being the closing price on
26 August 2003, the date of approval of the rights issue at the EGM.

The adjustment factor of 0.9176 is calculated as follows:

      Theoretical ex-rights fair value per share        =   487.70  =  0.9176
-------------------------------------------------------    --------
  Fair value per share immediately before exercise of       531.5
                          rights

The theoretical ex-rights fair value per share is calculated as follows:

<TABLE>
<S>                                             <C> <C>
Fair value of all outstanding shares            +   Total amount received from exercise of rights
-------------------------------------------------------------------------------------------------
Number of shares outstanding before exercise    +   Number of shares issued in the exercise


=    (556.8m ordinary shares * 531.5 pence) + (309.3m A shares * 165 pence)    =  487.70
   --------------------------------------------------------------------------
                 556.8m ordinary shares + 309.3m A shares (1)
</TABLE>

(1) The A shares have been treated as part paid ordinary shares, two A shares
being equivalent to one ordinary share.

6. Adjusted basic earnings per share
Adjusted basic earnings per share has been calculated by dividing adjusted
profit for the period (see below) by the following adjusted weighted average
number of shares in issue:

(i)   Period ended 30 September 2003                    648.7 million
(ii)  Period ended 30 September 2002 (restated)         643.1 million
(iii) Year ended 31 March 2003 (restated)               643.2 million

The adjusted weighted average number of shares have been restated for all
periods prior to the rights issue using an adjustment factor based on the
consideration received from the first stage of the rights issue and assumed
proceeds from the second stage, which are due to be received in June 2005. The
adjustment factor is 0.8646 calculated using 531.5p per ordinary share, being
the closing price on 26 August 2003, the date of approval of the rights issue at
the EGM. This adjusted measure has been included to reflect the full bonus
element of the rights issue which arose at the first stage, as demonstrated by
the movement in the share price following the approval of the rights issue at
the EGM. On this basis there will be no further dilutive effect on the share
price arising from the subscription of the second tranche.

The adjustment factor of 0.8646 is calculated as follows:

      Theoretical ex-rights fair value per share         =   459.54   =  0.8646
--------------------------------------------------------    --------
  Fair value per share immediately before exercise of        531.5
                        rights

The theoretical ex-rights fair value per share is calculated as follows:

<TABLE>
<S>                                            <C> <C>
        Fair value of all outstanding shares   +   Total amount received from exercise of rights
---------------------------------------------------------------------------------------------------
Number of shares outstanding before exercise   +   Number of shares issued in the exercise

=    (556.8m ordinary shares * 531.5 pence) + (309.3m A shares * 165 pence) +    =    459.54
                            (309.3m A shares * 165 pence) (2)
  --------------------------------------------------------------------------------------------
           556.8m ordinary shares + 309.3m A shares + 309.3m A shares (2)
</TABLE>

(2) Based on consideration received from the first stage of the rights issue
(165 pence per A share) plus assumed proceeds from the second stage (165 pence
for a further A share). All A shares will then be consolidated and reclassified
as ordinary shares on the basis of one ordinary share for two A shares.

The adjusted profit for the period is before goodwill and exceptional items as
shown in the consolidated profit and loss account. It excludes:

(i)   Period ended 30 September 2003 -(pound)4.3 million in respect of goodwill
      amortisation and non-operating exceptional items totalling(pound)nil
      million.

(ii)  Period ended 30 September 2002 - (pound)3.0 million charge in respect of
      restructuring costs, (pound)34.0 million in respect of an exceptional
      credit on withdrawal from infrastructure management in the Americas,
      (pound)25.5 million exceptional charge from the FRS 11 adjustment to the
      carrying value of the telecoms assets, (pound)5.8 million exceptional tax
      credit and (pound)3.5 million in respect of goodwill amortisation;

(iii) Year ended 31 March 2003 - (pound)3.8 million charge in respect of
      restructuring costs, (pound)34.0 million in respect of an exceptional
      credit on withdrawal from infrastructure management in the Americas,
      (pound)25.5 million exceptional charge from the FRS 11 adjustment to the
      carrying value of the telecoms assets, (pound)9.4 million exceptional tax
      credit and (pound)7.5 million in respect of goodwill amortisation.

Adjusted basic earnings per share excluding deferred tax has been derived by
taking the adjusted profit for the period as above and excluding the deferred
tax credit in the period of (pound)7.1 million (2002: (pound)49.4 million
charge).

7. Adjusted interest cover
Adjusted interest cover is calculated as the number of times the interest charge
for the period is covered by profit from continuing operations before
non-operating items, interest, taxation, exceptional items and goodwill
amortisation. This measure has been included to provide information on the
ability of the underlying business to finance its operations.

8. Interest cover
Interest cover is calculated as the number of times the interest charge for the
period is covered by profit on ordinary activities before interest.

9. Adjusted dividend cover
Adjusted dividend cover is calculated by dividing profit for the period before
exceptional items and goodwill amortisation by the dividend charge. This measure
has been included to provide additional information about the company's core
business performance.

10. Dividend cover
Dividend cover is calculated by dividing profit for the period by the dividend
charge.

</TABLE>

Prior period dividends per ordinary share have been re-presented for comparative
purposes to take account of the bonus element of the first stage of the rights
issue. The factor applied to the prior period dividends is 0.9072, calculated
using 576.0 pence per ordinary share, this being the closing price on 25 July
2003, the last business day prior to the announcement of the rights issue. For
example, the re-presented dividend per ordinary share for the period ended 30
September 2002 is calculated by multiplying the dividend per ordinary share of
15.5 pence by the factor of 0.9072.

The interim dividend of 14.43 pence per ordinary share and 7.215 pence per A
share will be paid on 9 February 2004 to shareholders on the register at the
close of business on 19 December 2003. The ex-dividend date for the interim
dividend is 17 December 2003.

12. Summary of Differences Between UK and US Accounting Principles Generally
Accepted
The interim consolidated financial statements of the group as of and for the six
month periods ended 30 September 2003 and 30 September 2002 are unaudited and
have been prepared in accordance with UK GAAP and the rules and regulations of
the Securities and Exchange Commission for interim financial reporting. Certain
information and footnote disclosures normally included in financial statements
prepared in accordance with UK GAAP have been condensed or omitted pursuant to
such rules and regulations. UK GAAP differs in certain respects from accounting
principles generally accepted in the United States of America (US GAAP).

Differences which have a significant effect on the unaudited consolidated net
income, shareholders' equity and financial position of the group are set out
below. In the opinion of management, the summary of GAAP differences set out in
this footnote reflects all adjustments which are necessary to present fairly the
financial position, results of operations and cash flows in accordance with US
GAAP for the interim periods. The financial statements should be read in
conjunction with the audited consolidated financial statements and notes thereto
included in the Company's Annual Report on Form 20-F for the year ended 31 March
2003. The results for the six month period ended 30 September 2003 are not
necessarily indicative of the results that may be expected for the year ending
31 March 2004.

As described in note 2, during the period ended 30 September 2003 the group
announced a 5 for 9 rights issue, structured so that the proceeds are received
in two stages. The first tranche was received during September 2003. Basic and
diluted earnings per share have been adjusted for all periods prior to the
rights issue to reflect the bonus element of the rights issue as required by
Financial Reporting Standard No. 14, Earnings per Share. Further details of the
adjustment are given in note 5. The same adjustments are required under US GAAP.

In the interim period ended 30 September 2003 the group has adopted for the
first time Statement of Financial Accounting Standards No. 143 ("SFAS 143"),
Accounting for Asset Retirement Obligations, Statement of Financial Accounting
Standards No. 145 ("SFAS 145"), Rescission of FASB statements nos. 4, 44 and 64,
Amendment of FASB Statement No. 13 and Technical Corrections, Statement of
Financial Accounting Standards No. 149 ("SFAS 149"), Amendment to Statement 133
on Derivative Instruments and Hedging Activities, Statement of Financial
Accounting Standards No. 150 ("SFAS 150"), Accounting for Certain Financial
Instruments with Characteristics of both Liabilities and Equity and FASB
Interpretation No. 46 ("FIN 46"), Consolidation of Variable Interest Entities
(VIEs), for new VIEs created since 1 February 2003. The adoption of these
standards has had no material effect on the interim financial position, results
of operations or cash flows.

</TABLE>

(a)      Pensions
Under UK GAAP, the group has recognised a pre-paid pension cost of (pound)77.5
million and (pound)58.5 million as of 30 September 2003 and 31 March 2003,
respectively. Under US GAAP, the group has recognised a pension liability of
(pound)315.5 million (net of prepayment of (pound)39.0 million) and (pound)322.9
million (net of prepayment of (pound)31.6 million) as of 30 September 2003 and
31 March 2003 respectively, of which (pound)350.4 million and (pound)350.4
million has been recorded within accumulated other comprehensive income as of 30
September 2003 and 31 March 2003, respectively. (pound)4.1 million was recorded
as an intangible asset at 30 September 2003 and 31 March 2003.

(b)      Goodwill
Under US GAAP the gross goodwill adjustment as at 30 September 2003 and 31 March
2003 was (pound)1,068.4 million. The accumulated amortisation adjustment under
US GAAP as at 30 September 2003 and 31 March 2003 was (pound)159.7 million and
(pound)164.0 million respectively.

Goodwill amortisation including that related to investments in joint ventures
under UK GAAP in the periods ended 30 September 2003 and 2002 was (pound)4.3
million and (pound)3.5 million, respectively.

Goodwill previously written off to reserves in the period ended 30 September
2003 and year ended 31 March 2003 of (pound)nil and (pound)0.9 million
respectively was released from reserves in relation to disposals under UK GAAP.

(c)     Impairment of long-lived assets
In the period to 30 September 2002, in accordance with FRS 11, the group
performed an impairment review within its telecommunications business. This
resulted in an exceptional adjustment to value of (pound)25.5 million
representing tangible assets of (pound)14.6 million, intangible assets of
(pound)8.6 million and goodwill of (pound)2.3 million. Under US GAAP, there is
no indication of impairment of long-lived assets, in the telecommunications
business on an undiscounted cash flow basis in accordance with SFAS 144 in the
periods ended 30 September 2003 or 2002. In addition, no impairment of goodwill
under SFAS 142 was required in the periods ended 30 September 2003 or 2002. The
tangible and intangible assets impaired under UK GAAP continue to be depreciated
under US GAAP resulting in a charge to income of (pound)1.6 million and
(pound)nil in the periods ending 30 September 2003 and 2002, respectively.

(d)      Fair value of derivative instruments
In accordance with the transition provisions of SFAS 133, the group recorded, at
1 April 2001, a net-of-tax cumulative-effect reduction of (pound)88.1 million in
accumulated other comprehensive income within shareholders' equity to recognise
at fair value all derivatives that were previously designated as cash flow type
hedging instruments. Of the transition adjustment of (pound)88.1 million in
accumulated comprehensive income, (pound)56.4 million has been reclassified into
earnings at 30 September 2003 ((pound)45.5 million at 31 March 2003).

Additionally, a fair value adjustment recognised in accordance with the
transition provisions of SFAS 133 increased debt by (pound)163.0 million which
was offset by a corresponding amount to record derivatives previously designated
as fair value type hedging instruments. The fair value adjustment to debt is
being amortised over the period of the debt in accordance with the transitional
rules.

At 30 September 2003 and 31 March 2003, the balance sheet includes current
derivative assets of (pound)320.3 million and (pound)379.3 million, current
derivative liabilities of (pound)23.2 million and (pound)23.2 million and
non-current derivative liabilities of (pound)228.8 million and (pound)260.2
million, respectively.

(e)      Revenue and profit recognition
The reduction in revenue under US GAAP is (pound)5.2 million in the period ended
30 September 2003 ((pound)28.5 million in the period ended 30 September 2002).

(f)      Classification differences
In addition to the differences between UK GAAP and US GAAP related to the
recognition and measurement of transactions by the group, there are also a
number of differences in the manner in which items are classified in the
consolidated profit and loss account. These differences have no impact on net
income or shareholders' equity.

Provisions for liabilities and charges
Provisions for liabilities and charges under UK GAAP include (pound)5.0 million
((pound)9.4 million at 31 March 2003) which are due within one year and which
would be reclassified to current liabilities under US GAAP. The remainder of the
provisions would be reclassified as long-term liabilities under US GAAP.

Grants
Under UK GAAP, grants (other than capital contributions towards infrastructure
assets) are disclosed within deferred grants and contributions as creditors in
the balance sheet. Under US GAAP, these amounts would be set against the assets
to which they relate and (pound)290.1 million ((pound)285.5 million at 31 March
2003) would be reclassified from long-term liabilities to tangible fixed assets.

Equity method investments
Under UK GAAP, the share of joint ventures' operating results excludes share of
joint ventures' interest and share of joint ventures' tax. These amounts are
included within "Interest payable and similar charges" and "Taxation charge"
respectively. Under US GAAP, all of these amounts are included within "Equity in
earnings/(losses) of affiliates". Under UK GAAP investments in joint ventures
are classified under the heading investments within fixed assets. Under US GAAP,
investments in joint ventures are classified as investments in equity
affiliates.

(g)      Cash flows
Set out below is a summary consolidated statement of cash flows under US GAAP:

UITF Abstract 38 ("UITF 38"), Accounting for ESOP Trusts
UITF 38, issued in December 2003, supersedes UITF Abstract 13. It changes the
presentation of an entity's own shares held in an ESOP trust from requiring them
to be recognised as assets to requiring them to be deducted in arriving at
shareholders' funds. Companies are required to adopt UITF 38 for accounting
periods ending on or after 22 June 2004. The group does not expect the adoption
of UITF 38 to have a material effect on the consolidated financial position,
results of operations or cash flows.

FASB Interpretation No. 46 ("FIN 46"), Consolidation of Variable Interest
Entities
FIN 46, issued in January 2003, provides guidance for identifying a controlling
interest in a Variable Interest Entity ("VIE") established by means other than
voting interests. FIN 46 requires consolidation of a VIE by an enterprise that
holds such a controlling interest. This Interpretation has been adopted for VIEs
created after 31 January 2003. For VIEs in which the group holds a variable
interest that it acquired before 1 February 2003, the Interpretation will be
effective as of 1 April 2004 or at such earlier date at which one or more of the
following occur: (i) the entity's governing documents or the contractual
arrangements amongst the parties involve change, (ii) the equity investment or
some part thereof is returned to the investors, and other parties become exposed
to expected losses, or (iii) the entity undertakes additional activities or
acquires additional assets that increase the entity's expected losses.


CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This interim results statement contains certain forward-looking statements with
respect to the financial condition, results of operations and business of the
company.

Statements that are not historical facts, including statements about the
company's beliefs and expectations, are forward-looking statements within the
meaning of the US Private Securities Litigation Reform Act of 1995. Words such
as "expects", "anticipates", "intends", "plans", "believes", "seeks",
"estimates", "potential", "reasonably possible" and variations of these words
and similar expressions are intended to identify forward-looking statements.
These statements are based on current plans, estimates and projections, and
therefore investors should not rely on them. Forward-looking statements speak
only as of the date they are made, and the company undertakes no obligation to
update publicly any of them in the light of new information or future events.

Forward-looking statements involve inherent risks and uncertainties. The company
cautions investors that a number of important factors could cause actual results
to differ materially from those anticipated or implied in any forward-looking
statements. These factors include: (i) the effect of, and changes in, regulation
and government policy; (ii) the effects of competition and price pressures;
(iii) the ability of the company to achieve cost savings and operational
synergies; (iv) the ability of the company to service its future operations and
capital requirements; (v) the timely development and acceptance of new products
and services by the company; (vi) the effect of technological changes; and (vii)
the company's success at managing the risks of the foregoing. The company
cautions that the foregoing list of important factors does not address all the
factors that could cause the results to differ materially.
