What is an EPC?

An EPC is effectively a 5 page document that:

1. Expresses the energy rating of the building (A [highest] - G [lowest]) and a numerical value. It will look similar to the 'fridge' style EPC that is used in house sales.

2. Contains the total useful floor area, address of the property, name and address of the Energy Assessor and the date it was issued with a registered reference number.

3. Is accompanied by a recommendation report with suggestions of how the energy rating could be improved in the short, medium and long term.

The purpose of the EPC is intended to inform new tenants or buyers of a building's energy performance rating.

Energy Performance Certificates for Landlords and Home Owners determine how energy efficient homes are on a scale of A-G. The most efficient homes - which should have the lowest fuel bills - are in band A. The certificate uses the same scale to define the impact a home has on the environment. Better-rated homes should have less impact through carbon dioxide (CO2) emissions. The average property in the UK South West London Surrey and Middlesex are in bands D-E for both ratings. The certificate for a landlord includes recommendations on ways to improve the home's energy efficiency to save money and help the environment.

The Energy Performance Certificate (EPC) is based on the RDSAPv3 procedure, which is a simplified version of the SAP2005. SAP is short for Standard Assessment Procedure and RDSAP for Reduced Data SAP. The EPC will be produced by Home Inspectors or Domestic Energy Assessors to be included as part of a Home Information Pack.

Why are Energy Performance Certificates being introduced?

It is fact that 'buildings' contribute over 50% of the carbon omissions in the UK. The introduction of EPCs will highlight the existing energy efficiency of a building and what can be done to make it more efficient - as part of the UK's commitment to tackling climate change.

How long are EPCs valid for?

At present an EPC for a rental property is valid for 10 years. However, if modernisations are carried out, it may be advantageous to have the property re-assessed to reflect the improvements.
