SAP calculations are used to ensure that new dwellings meet minimum energy performance standards (MEES). They are based on the pre-determined design of a dwelling. The SAP calculation is also known as a Predicted Energy Assessment and it provides a rating of the energy performance of a building against Part L of the building regulations. Most newly built dwellings are required to have an Air Pressure Test before the final building certificate can be issued. The results of this test are then supplied to the assessor who then edits the SAP Calculation and ensures that the completed dwelling is compliant with Part L.

If you are planning to rent or sell a property, an energy assessment is an essential step. An EPC is a legal requirement for selling or renting residential properties in the UK. It rates the property from A (best performance) to G (worst performance) based on its energy efficiency and environmental impact. If you have a property with an F or G rating, the deadline to rent it out is April 1st 2018.
