What is a Display Energy Certificate (DEC)?

A Display Energy Certificate (DEC) shows the actual energy performance of a building, based on its metered energy use over the previous 12 months.

• Required for: Public buildings (and certain publicly visited buildings) with a floor area over 250 m².

• Purpose: To make energy use in public buildings transparent and encourage improved efficiency.

• Energy Rating: Uses a scale from A (most efficient) to G (least efficient).

• Accompanied by: A Recommendation Report, which lists cost-effective recommendations for improving energy performance.

• Validity:

  • Buildings over 1,000 m² → DEC valid for 1 year, Advisory Report for 7 years.

  • Buildings 250–1,000 m² → DEC valid for 10 years.

  • Failing to display a valid DEC (in a visible, public place)

    £500

  • Not having a valid recommendation report (in possession or control)

    £1,000

If you sell or lease a commercial building, you must provide an EPC for the buyer/tenant.
