for underfloor systems:
Note 16 : Improvement Y. Recommendation applicable only if hot water if from a cylinder or a combi boiler. If one shower it is System A. If more than one shower the first shower has System A and others System B, with System A is assigned to a room with shower and no bath if there is one. For System A use 695001, for System B use 695002.  
Note 17: Improvement G: Two thermostats if TFA is large than 150 m 2 , Boiler controls are considered to be part of boiler installation.
Heating upgrades
An improvement to a heating system by adoption of any of the following measures:
I, J, K, L2, M, R, S, T, Z1, Z2
is taken as extending the main heating system to the whole dwelling where that is not the case in the existing dwelling. Thus when implementing any of the above measures, the number of heated habitable rooms is to be set equal to the number of habitable rooms. This rule affects the results where there are unheated habitable rooms and no identified secondary heater. If there is an identified secondary heater, the secondary heater remains throughout the sequence of calculations of improvement measures. Also, in the case of measure T upgrading storage heaters to a condensing gas boiler if the secondary heating has been given as portable electric heaters the secondary heating becomes none after the upgrade.
Heating upgrades
In the case of measure T, if the existing heating is storage heaters or off-peak underfloor electric heating (401, 402, 404, 408, 421, 422) change the electric meter to single.
Heating upgrades
Heating upgrades when there are two main systems
In the case of measure I (upgrade boiler, CPSU or range cooker, same fuel) where both systems each use the same fuel, apply the improvement to both boilers as applicable (i.e. boiler is non-condensing) as a single step. If the result attains the SAP increase criterion make the recommendation on the EPC using the improvement text applicable to main system 1 if both boilers are being upgraded.  
In the case of any other combination of main heating systems, apply the improvement to system 1 only. This includes measure I where that is relevant to main system 1 but not main system 2, as well as consideration of measures J, K, M, R, S, T, J2, Z1, Z2.  
Heating control upgrades when there are two main systems
Apply the improvement to the controls on system 1 only, except apply improved controls to both boilers if both replaced.
Central heating pump age for improvement measures

Central heating pump age for improvement measures
Where the heating is upgraded to a system which needs a central heating pump (J, J2, K, Z3, I, R, S, T), if the existing dwelling has a one this is retained (pump age is unchanged). If the existing dwelling has no central heating pump then a new one is added (pump age is 2013 or later).
Definitions of the Recommendation Status
For testing purposes only each improvement mentioned in the list can be indicated as being one of the following: Only those with status "Recommended" or "Alternative" appear on the EPC.  
|  Status | Meaning | Example  |
| --- | --- | --- |
|  Not considered | Measure not considered in this case | Insulation measure for new dwelling  |
|  Not applicable | Inapplicable in this case | Loft insulation for ground or mid-floor flat  |
|  Existing Unknown | Existing condition not known | Cylinder insulation when cylinder inaccessible  |
|  Already installed | Dwelling already has measure to at least that recommended in the above Table of measures | Originally clear cavity walls but cavity has been filled  |
|  Equivalent already installed | Dwelling already has equivalent measure to at least that recommended in the above Table of measures | Cavity wall is unfilled but has internal or external insulation to give $\mathrm{U}<=0.6$  |
Definitions of the Recommendation Status
|  Error | Incompatible data | Solid wall marked as having cavity fill  |
|  Recommended | Included in the quantified recommendations on the EPC | Increase insulation of hot-water cylinder  |
|  Alternative | Recommended as an alternative measure | Heat pump  |
|  Superseded | A measure further down the list applies instead | Upgrade oil boiler to condensing oil boiler, but mains gas is available so instead recommendation is for condensing gas boiler  |
|  SAP increase too small | SAP improvement is less than the applicable threshold for the measure | $100 \%$ low energy lights raises SAP by 0.3 points.  |
|  Cost saving too small | Total energy cost reduction is less than $£ 10$ when recalculated using current fuel prices | Increase in SAP rating is 0.51 points, but total energy cost increases (because of differential price changes since the values in SAP Table 32 were set)  |
Definitions of the Recommendation Status
|  Recommendation cancelled | Assessor deselected the recommendation | PVs when roof significantly over-shaded  |

Software implementation recommendations:
All remaining improvement measures are to be written to the XML so that they are included on the EPC. (Note: for an existing dwelling the user is able to de-select measures. That is not the case for new-build EPCs and the option to de-select measures should not be available in the case of new-build.)  
The effect of each improvement measure is determined by implementing the measures in turn and calculating the results. The order of implementing the measures is to be as set out below. Implementing measures is done by amending the input data, e.g. to increase the percentage of low-energy lights to $100 \%$, and the calculation is re-done.
The results for each measure consist of:  
- the incremental cost saving in $£ /$ year from implementation of the measure
- the cumulative SAP band and SAP rating (i.e. after implementing all measures so far)
- ditto environmental impact

- the cumulative SAP band and SAP rating (i.e. after implementing all measures so far)
- ditto environmental impact  
The total running costs, CO2 emissions and primary energy are calculated after implementing all applicable measures. They are totalled separately for space heating, water heating and lighting. The electricity for pumps and fans together with any additional standing charge is included with the space heating, except for electricity for a solar water heating pump and for electric keep-hot by a keep-hot combi boiler which are included with the water heating.
RoSAP 10 (12 February 2024)
The fuel prices to be used for the calculation of incremental savings and total running costs are those in Table 191 of the Product Characteristics Data File (pcdf2012.dat). (Note: The prices in Table 191 are used only for calculation of costs and savings on EPCs. Any SAP rating, whether initial, after incremental improvements or final, must in all cases be based on the prices given in Table 32. Thus software must maintain two sets of fuel prices, one set for calculation of SAP ratings and one set for calculation of running costs and savings.)
