Any dwelling created after 1st April 2008 must have an EPC certificate produced using full SAP methodology. This includes new builds, conversions, and properties where the number of dwellings has changed, such as a house converted into two flats. A full SAP EPC can be used for sale or rent just like the usual (RdSAP) version and is valid for 10 years.
A SAP EPC is typically ordered as a compliance bundle with other services, including:
- Air Tightness Testing
- Sound Insulation Testing
- Ventilation Flow Rate Testing
- Internal Water Usage Calculations
