What is an Energy Performance Certificate?

An Energy Performance Certificate (EPC) shows the Energy Efficiency Rating (EER) and an Environmental Impact Rating (EIR) of a property on an A-G scale (A being the most efficient and G being the least).

The EER is rated in terms of energy costs, while the EIR is rated in terms of carbon emissions. These alphabetical bands are linked to a numerical score from 0-100 points (100 being the most efficient and 0 being the least).

What is the difference between the EPC and full SAP EPC?


The energy rating on your EPC is based on the Standard Assessment Procedure (SAP) however existing properties are assessed using the Reduced Data SAP (RdSAP) which is a simplified version of the full SAP methodology. The EPC requires fewer data inputs than the full SAP and is a less invasive survey.

A Full SAP EPC must be undertaken on properties built after April 2008, this includes new builds, conversions, and changing the number of dwellings within a property for example a 4-bedroom house changing into 2 flats. The full SAP EPC can be used for sale and rental in the same way as a standard EPC (RdSAP) and is valid for 10 years.

Retrofit Assessment


The PAS 2035 Retrofit Assessment is carried out prior to any retrofit installation and should always be carried out by a fully qualified Retrofit Assessor. Project scope depends on the required improvement measures, risk level, and the type of building.
