Do you need Sap calculations for Part L of the building regulation? Then we are here to help. Contact us for a quote for your project.
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.

Here we have presented the most typical questions asked about SAP Calculations in Broad Green.
Sap Calculations, What Exactly Are They
This really is quite possibly the most common query asked. Check out Andrea’s video explanation above, or read the full explanation here on the right.
What Is The Cost Of Sap Calculations
If there are various properties with similar types of constructions, then reductions may apply. But typically for a single dwelling the charge would be in the area of £120 – £300. By providing the plans, you will be able to get yourself a fixed quote.
What Is The Difference Between Sap and EPC
Before we explain the difference, here 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 computations of pre defined data set of a buildings design that’s created to show the energy performance of a dwelling. An EPC or Energy Performance Certificate is a summary report created from the Sap calculations which 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 the property.
There are actually two types of EPCs. The first is a SAP EPC that is created from building plans where all of the components of the construction are known. This would normally be required by building control to show that a dwelling satisfies specified targets essential to the building regulations. Building control would also have to see the SAP calculations which shows in greater detail whether all the components going into the property conform to the building regulations.
The 2nd sort of EPC is the standard one that would be required if you are selling, or renting a property. This kind of EPC uses what’s called rdSAP, which means Reduced Data Standard Assessment Procedure, which is used where certain thermal values of, for instance, the walls, roof, floors, etc, are not precisely known on an existing property. In this instance assumed thermal values are used depending on the age of the property. This particular EPC would be no good to show compliance with any building regulations. Sometimes building control would simply ask you for the EPC, however what they would really need are the Sap calculations (which is the data behind the EPC) and the SAP EPC (which is a summary report from the Sap calculations).
Still confused, after that phone us for additional advice.
What Are As Built SAP Calculations
These will be the finished set of SAP calculations generated after the dwelling has been completed to confirm that it is compliant with Part L1A of the building regulations. Ahead of the project starting, it ought to have had a set of “Design Sap” calculations to show that the planned construction, on paper at least, would be compliant with Part L1A.
Can I Do The Sap Calculation Myself
Unfortunately this is not something that can be done yourself. Sap calculations need to be carried out by an On Construction Domestic Energy Assessor or OCDEA, using approved Government software. The Assessor needs to be approved under one of several certification schemes and is regularly audited to maintain 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 dwelling need to have Sap calculations to show compliance with Part L1A (Conservation of fuel and power in new dwellings) of the building regulations.
Sap Calculations For Extensions
It’s now quite fashionable to get large bi-folding doors, sky lights and large quantities of glazing on new extensions. But under the existing building regulations the amount of glazing can be a maximum of 25percent of the floor area of the new extension. So over compensations in the thermal elements in other areas within the property will need to be made to demonstrate that the CO2 emissions from the current house and the planned extension is not any worse than the existing house and an extension where the glazing is within the allowed amount judged against Part L1B of the building regulations.
You should have SAP calculations to find solutions and demonstrate compliance.
Sap Calculations For Conversions
When you are modifying the use of a dwelling, you will require Sap calculations. {The new dwelling will have to comply with Part L1B of the building regulations.}
Will 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
