Since October 2008 all properties - homes, commercial and public buildings - when bought, sold, built or rented need an EPC. Larger public buildings also need to display an energy certificate. For latest details visit the government website.

A commercial energy assessor is qualified to provide EPCs for non-residential properties. Their level of qualification is explained below:

Level 5 - EPCs for very complex buildings, including those with large amounts of glass and those which are curved

Level 4 - EPCs for complex buildings without those special features listed above.

Level 3 - EPCs for simple buildings

Here is a list of local commercial energy assessors. Email or telephone for details.
