Enica provide DEC assessment and renewal services across the UK. Suitable for single buildings or portfolios, we offer a competitive service.

By 9th July 2015, all qualifying buildings with a floor area >250m2 will require a DEC and Advisory Report which will last for 10 years. This effectively means buildings between 250m2 and 499m2 will require assessment as well as those which are larger.

DECs are required for public buildings with a useful space of 500m2 or more
They are required by:

30/12/2008 >1000m2 with annual renewal (AR renewal every 7 years)
09/01/2013 >500m2  with renewal every 10 years
09/07/2015 >250m2  with renewal every 10 years

The Display Energy Certificate and Advisory Report are both mandatory requirements.

Display Energy Certificates provide an energy rating of a building from A to G, where A is very efficient and G is the least efficient.  These ratings are based on the actual amount of metered energy used by a building over a period of 12 months.  The DEC should be A3 in size and must be clearly displayed in a place clearly visible to the public.  The DEC is valid for a period of 12 months for buildings over 1000m2 and 10 years for over 500m2.

Occupiers of buildings that require DEC’s must have a valid Advisory Report in their possession or control.  An Advisory Report highlights recommendations to improve the energy performance of the building.  The Advisory Report is valid for a period of 7 years in buildings over 1000m2 and 10 years over 500m2.

DEC’s & AR’s must be carried out by an accredited Energy Assessor and logged in a national register with a unique reference number.
