Display Energy Certificates (DECs) and Advisory Reports (ARs)

Coles Knapp are accredited to provide DECs and ARs and offer a quick, reliable and competitive service. We are happy to assist those who are new to DECs with compliance information and guidance. We've dealt with all sorts of building DECs from hospitals to schools to offices to leisure centres, and with some large portfolios, so call us if you require a quote or for a chat about your requirements.

Since January 2013 Display Energy Certificates (DECs) need to be prominently displayed in buildings over 500m2 that are occupied by public authorities (or institutions providing a public service) that are visited by the public.

DECs and Advisory Reports for buildings from 500m2 - 999m2 have a 10 year validity, whereas DECs for those for buildings of 1000m2 and higher have a one year validity, with the Advisory Reports lasting 7 years.

Many organisations who do not require DECs by law are carrying them out voluntarily to enable them to monitor and target reductions in their energy use.
