Why Do You Need A DEC?
Legislative Basis
In the UK, DEC legislation came into force around 2008 following the introduction of The Energy Performance of Buildings Regulations 2007, made under the European Communities Act 1972. These regulations set out the framework for Energy Performance Certificates and Display Energy Certificates.
What changes have been made?
Ongoing Revisions
The rules have been updated several times, most notably by The Energy Performance of Buildings (England and Wales) Regulations 2012, and subsequent amendments in 2015 and 2018. These changes clarified the certificate validity periods, the buildings subject to requirements, and the obligations relating to the AR.
