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.

Sap Calculations, Exactly What Are They?
This is certainly quite possibly the most common question asked. Have a look at Andrea’s video explanation above, or read the full explanation here on the right.
Sap Calculations, How Much Are They
We would be pleased to provide discount rates, especially for properties which are of the same or very similar design. For single dwellings then you would be looking in the region of £120 – £300 depending upon the difficulty of your building along with the size. By supplying the plans, you will be able to get yourself a fixed price quotation.
What Is The Difference Between Sap and EPC
Before we explain the difference, this is what you will require 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 computations of pre defined data set of a properties design that’s created to demonstrate the energy effectiveness of a building. EPC is short for Energy Performance Certificate and it’s a summary report from the SAP calculations in an simple to comprehend report, that can also be used to market or rent a property.
There are really 2 types of EPCs. The first is a SAP EPC which is created from building plans where all of the components of the building are known. This would normally be required by building control to demonstrate that a dwelling satisfies certain targets required by the building regulations. Building control would must also see the SAP calculations which illustrates in detail whether all of the components going into the property conform to the building regulations.
The 2nd type of EPC is the common one that will be necessary for anyone who is selling, or renting out a property. This kind of EPC uses what’s called rdSAP, which is short for Reduced Data Standard Assessment Procedure, and is used where specific thermal values of, such as, the walls, roof, floors, etc, usually are not precisely known on an established property. In this instance assumed thermal values are used depending on the age of the property. This sort of EPC would be no use to demonstrate compliance with any building regulations. Sometimes building control would simply ask you to get an EPC, but what they would really need to have are the Sap calculations (which is the information 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 final set of SAP calculations produced after the dwelling has been completed to confirm that it is compliant with Part L1A of the building regulations. Prior to the construction starting, it ought to have had some “Design Sap” calculations to demonstrate that the planned dwelling, in theory at least, would be compliant with Part L1A.
How To Do Sap Calculations
Unfortunately this is not something you can do by yourself. The calculations need to be carried out by an On Construction Domestic Energy Assessor or OCDEA, using approved Government program. The Assessor must be approved under one of the certification schemes and is also regularly audited to keep their certification.
What Info is Needed 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 dwelling need Sap calculations to demonstrate compliance with Part L1A (Conservation of fuel and power in new dwellings) of the building regulations.
Sap Calculations For Extensions
It’s now fashionable to have large bi-folding doors, sky lights and large amounts of glazing on new extensions. However with the present building regulations the quantity of glazing must be no more than 25% of the floor area of the new extension. Therefore over compensations on the thermal elements in other places of the property will need to be made to demonstrate that the CO2 emissions from the existing house along with 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 illustrate compliance.
Sap Calculations For Conversions
When you are altering the use of a dwelling, you will need Sap calculations. {The new dwelling will have to comply with Part L1B of the building regulations.}
Will 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
