Checking the authenticity of a DEC
Posted by Mike Gordon on 22 July 2015 12:39 PM

A DEC must be lodged, by an accredited energy assessor, in the central register for non-dwellings which contains all DECs and advisory reports. It is not possible to opt out of this process.

If you have commissioned a DEC for your building you will receive a copy of the certificate to display as required by the regulations.

A DEC is identified by a unique reference number If you have been given a DEC and wish to check its authenticity, you can access the register by entering the reference number on the certificate. You can also search the register by entering the address of the property.

If you cannot find your certificate in the register or have any concerns regarding the authenticity of the information contained within the certificate, you should contact the accreditation body of the energy assessor who produced the DEC. The energy assessor details, their accreditation scheme and their membership number should be on the certificate.

A lodged DEC becomes legal when the accompanying advisory report has been lodged, and vice versa.
