What are SAP Calculations and are they needed for conversions?
You need SAP calculations to comply with Approved Document Part L (Fuel and Power). These regulations aim to ensure that residential properties meet basic energy performance standards.
Your conversion will need a SAP calculation if there is a ‘material change of use’ or “Change of Energy Status”. Some of the most common examples of this are as follows:
- After conversion, the building will be a dwelling when it wasn’t before – e.g. barn conversion
- After conversion, the building will contain a flat which it did not before
- The number of dwellings in a building changes – e.g. splitting a large home into flats
If your conversion falls into one of these categories, you will need to get SAP calculations and EPCs to show that each of the new dwellings meet the required energy efficiency levels.
If you are extending or building a new property see our SAP Calculation page for more information.
How Is Compliance with Part L Demonstrated?
You can demonstrate compliance with Part L using several methods; however, the most common SAP calculations for conversions are as follows:
- SAP Calculations (Section 11.7 Compliance): This method can be used to demonstrate compliance if all areas meet the minimum standards.
- SAP Calculations (Section 11.8 Compliance): This is typically required for balancing overall thermal performance if some areas don’t meet individual U-value targets.
An experienced SAP assessor will guide you on the best approach based on your project’s specifications and help you achieve the best possible EPC rating.
How quickly can I have my SAP Calculations?
It depends on the size of your property however; on average it takes about 3 days to complete. We will require a full set of plans and building details to start the process.
