Display Energy Certificate Conventions
Display Energy Certificate (DEC) conventions (issue 1.0), must be applied by all certified DEC energy assessors.
Download the first of the DEC Conventions (issue 1) here.
For audit and management purposes, the conventions must be applied on the dates shown in the 'Implementation Date' column on the right-hand side of the table. These conventions will be included as part of future quality assurance checks of the assessments you have undertaken, and the DEC reports produced, thereafter.
If you have any questions about the conventions please email firstname.lastname@example.org. Where appropriate, it can be discussed at a future meeting of the Conventions Group. The conventions must be applied as issued, even if you believe that a convention may require further clarification, until such time as the Conventions Group have had the opportunity to discuss the issue in more detail. Any subsequent changes to the conventions will then be circulated to all DEC assessors.
