What are SAP Calculations and are they needed for conversions?

You need SAP calculations to comply with Approved Document Part L. 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 Calculations for Extensions and SAP Calculations pages.

How quickly can I have my SAP Calculations & SAP EPC?

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.

If you need an SAP energy performance certificate for a property in Hertfordshire, Kent, Essex, London or anywhere else in the UK – Assessment Hive can help.
