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.

Rather than trawl through a whole website to obtain the answers you’re interested in, we have supplied answers to the 10 most typical queries asked about SAP in Mile End.
So, What Are Sap Calculations
This really is quite possibly the most frequent question asked. Take a look at Andrea’s video explanation above, or read the full explanation here on the right.
How Much Do Sap Calculations Cost
We would be pleased to offer you discounts, especially for multiple dwellings which are of the same or very similar construction. But typically for a single property the price will be in the region of £120 – £300. By providing the plans, it will be possible to get a fixed price quote.
What’s The Difference Between Sap and EPC
Before we get to the differences, here is what you will need depending on your project.
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 display the energy performance of a property. An EPC or Energy Performance Certificate is a overview report derived from the Sap calculations which produces a SAP score from 0 to 100. This score is expressed on the EPC as A the highest to G the lowest. It will also list recommendations which would increase the rating of the property.
There are actually two kinds of EPCs. First is a SAP EPC that is created from building plans when all of the elements of the building are known. This will normally be required by building control to show that a property satisfies specific targets essential to the building regulations. Building control would also have to see the SAP calculations which shows in detail whether all of the components going into the property conform to the building regulations.
The 2nd variety of EPC is the typical one that would be required when you are marketing, or renting a property. This type of EPC uses what’s called rdSAP, which stands for Reduced Data Standard Assessment Procedure, which is used where particular thermal values of, for instance, the walls, roof, floors, etc, are not precisely known on an established property. In this situation assumed thermal values are used according to the age of the property. This particular EPC will 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 need to have are the Sap calculations (which is the information behind the EPC) and the SAP EPC (which is actually summary report from the Sap calculations).

What Are As Built SAP Calculations
These will be the final set of SAP calculations generated after the building has actually been completed to confirm that it is compliant with Part L1A of the building regulations. Ahead of the construction starting, it should have had some “Design Sap” calculations to show that the proposed dwelling, on paper at least, will be compliant with Part L1A.
How To Do Sap Calculations
No, this is not some thing you can do by yourself. The calculations have to be carried out by an On Construction Domestic Energy Assessor or OCDEA, using approved Government software. The Assessor must be certified under one of the certification schemes and is also regularly audited to keep their certification.
What Info 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
All new property need to have 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 have large bi-folding doors, sky lights and large quantities of glazing on new extensions. But with the existing building regulations the amount 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 parts of the property will need to be made to demonstrate that the CO2 emissions coming from the current house along with the proposed extension is no worse than the existing house and an extension where the glazing is within the permitted amount judged against Part L1B of the building regulations.
You need SAP calculations to find solutions and illustrate compliance.
Sap Calculations For Conversions
When you are modifying 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 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
