What Exactly Are Sap Calculations?
SAP is short for Standard Assessment Procedure and is the UK government’s procedure for calculating the energy performance of residential properties. The calculations are required to demonstrate your building conforms with specified energy targets laid down in the building regs.
That’s pretty much it in a simple summary.

What does SAP mean?
Have building control, or even your architect asked you to get sap calculations?
Why will you need them and exactly what are sap calculations anyhow? Then read on.

When Are SAP Calculations Needed?
Sap calculations are usually required for 3 main reasons.
1. For all new properties.
2. For a dwelling change of use, for example altering a commercial building to residential flats.
3. For overglazed extensions.
The two main areas that the sap calculations will be looking at is that the carbon emissions from the dwelling are within set tolerances and that certain elements of the property, such as the walls, windows , floors and roof comply with certain thermal energy targets.
A good set of construction drawings will need to be given to the Assessor, because all the calculations are done from the building drawings ,so usually there is no need to visit the property.
Your Assessor will advise you of precisely what is needed. When the calculations are completed, an Energy Performance Certificate or EPC can also be produced.
If your sap calculations show that your property is not compliant, then our Assessor will give you advice on upgrades that can be made to make it so.
It could be costly if you realise at a late stage in the construction that the building is not compliant. So it is wise to liaise with the Assessor as early on during the project as possible.

So, What Are Sap Calculations
This really is probably the most frequent query asked. Take a look at Andrea’s video explanation above, or read the full explanation here on the right.
Sap Calculations, How Much Are They
If there are multiple properties with similar forms of constructions, then discounts may apply. For single dwellings you would be looking in the region of £120 – £300 dependant upon the intricacy of your construction along with the size. By supplying the plans, it will be possible to get yourself a fixed quotation.
What Is The Difference Between Sap and EPC
Before we explain the difference, this is what you will need depending on your job.
For a new build property you’ll need – SAP calculations and an EPC.
For dwelling change of use or conversion you’ll need – Sap Calculations and an EPC.
For overglazing on an existing dwelling you’ll – Sap calculations only.
SAP or Standard Assessment Procedure are the calculations of pre defined data set of a properties design that’s put together to show the energy effectiveness of a dwelling. An EPC or Energy Performance Certificate is a overview report created from the Sap calculations that produces a SAP score from 0 to 100. This score is shown on the EPC as A the highest to G the lowest. It will also list suggestions which would improve the rating of your property.
There are actually 2 kinds of EPCs. The first is a SAP EPC that is produced from building plans when all of the components of the construction are known. This would normally be needed by building control to show that a property satisfies certain targets required by the building regulations. Building control would must also see the SAP calculations which shows in detail whether all the components going into your property conform to the building regulations.
The second type of EPC is the typical one that will be necessary when you are selling, or renting a property. This kind of EPC uses what’s called rdSAP, which is short for Reduced Data Standard Assessment Procedure, and is used where specified thermal values of, for instance, the walls, roof, floors, etc, are not precisely known on an established property. In this case assumed thermal values are used based on the age of your property. This sort of EPC would be no use to show compliance with any building regulations. Sometimes building control would simply ask you to get an EPC, however what they would really require are the Sap calculations (which is the data behind the EPC) and the SAP EPC (which is a summary report from the Sap calculations).

What Are As Built SAP Calculations
These are the finished set of SAP calculations produced once the building has been completed to hopefully demonstrate that it is compliant with Part L1A of the building regulations. Prior to the project starting, it ought to have had some “Design Sap” calculations to show that the proposed dwelling, in theory at least, would be compliant with Part L1A.
How To Do Sap Calculations
No, this is not some thing you could do yourself. The calculations need to be carried out by an On Construction Domestic Energy Assessor or OCDEA, using approved Government computer software. The Assessor has to be approved under one of the certification schemes and is regularly audited to keep their accreditation.
What Information is Required For Sap Calculations
Your Assessor would advise you of exactly what is needed. Typically you would need the following:
- Floor Plans to include sections and elevations
- Orientation of the property
- Construction specification of walls, roof and floors
- Specification for all doors and windows
- Primary and secondary heating
- Provision for providing hot water
- Any renewable technology (if any)
Sap Calculations For New Build
Every new property need Sap calculations to demonstrate compliance with Part L1A (Conservation of fuel and power in new dwellings) of the building regs.
Sap Calculations For Extensions
It’s now modern to get large bi-folding doors, sky lights and large quantities of glazing on new extensions. But under the present building regulations the quantity of glazing must be no more than 25percent of the floor area of the new extension. Therefore over compensations on the thermal elements in other areas within the property will have to be made to show that the CO2 emissions coming from the existing house along with the proposed extension is not any worse when compared to the existing house and an extension where the glazing is within the permitted amount judged against Part L1B of the building regulations.
You should have SAP calculations to find solutions and illustrate compliance.
Sap Calculations For Conversions
When you are changing the use of a building, you will require Sap calculations. {The new dwelling will have to comply with Part L1B of the building regulations.}
Do I Need to have Sap Calculations
You will need Sap calculations for any of the following:
- Building a new property
- Changing the use of an existing property (e.g, a barn conversion, commercial building to residential)
- Extensions with more than 25% glazing
- Opening up the main house to an existing conservatory
- Extension where the extension is more than 50% of the original property wall area
- Garage conversions
- If requested by building control
