Display Energy Certificate
A Display Energy Certificate (DEC) shows how a building performs in use, based on recorded energy consumption. Its operational rating runs from A to G and helps building managers understand performance and identify opportunities for improvement.
NRG Assessments provides initial DECs, renewals and advisory reports for schools, colleges, council offices and other qualifying public buildings. We work across Birmingham, the West Midlands, Staffordshire and Derbyshire, with wider coverage for larger sites and portfolios.
Our work includes reviewing electricity and heating records, checking meter coverage and assessment periods, and identifying missing information before the assessment is completed. Where solar panels or shared heating systems are present, tell us so we can confirm the evidence needed.
To request a DEC quotation, send the building address, approximate floor area, existing certificate and available energy records. We can explain the next steps and check whether the advisory report also needs renewing.
What you need to know
Who Needs a DEC?
In England and Wales, a DEC is required for a building with a total useful floor area over 250 m² that is occupied, at least partly, by a public authority and frequently visited by the public. The certificate must be displayed prominently. Private organisations can obtain a DEC voluntarily. Depending on their occupation and use, qualifying buildings can include:
-
Schools and colleges
-
Hospitals and medical centres
-
Libraries
-
Council offices
-
Leisure and community centres
-
Museums and galleries

Non Compliance
A penalty charge notice of £500 for failing to display a DEC at all times in a prominent place clearly visible to the public, and £1,000 for failing to possess or have in their control a valid advisory report. In addition to these penalties, it will still be necessary to commission the documents.
