	Display energy certificates (DEC's) show the energy performance of a building based on actual energy consumption. For certain types of building, they must be displayed prominently in a place visible to the public and are intended to raise public awareness of the energy use of buildings.

An advisory report must also be prepared every seven years giving recommendations to owners and occupiers about making their building more energy efficient.

		+	= Updates =
		+
		+	In December 2024 the UK government published a consultation seeking views on the reform of the Energy Performance of Buildings (EPB) framework, for England and Wales (Scotland and now Northern Ireland being devolved matters). The consultation published by MHCLG and DESNZ and closed 26 February 2025, and covers:
		+
		+	* Improving regulations, applicability, quality, and data usage of domestic and non-domestic buildings
		+	* updating EPC metrics and refining requirements for both EPCs and DECs
		+	* improving data management protocols and strengthening quality control
		+	* revising air conditioning inspection reports (ACIRs)
		+
		+	The minimum energy efficiency standards (MEES) regulations are not being changed at this stage (but maybe reviewed at a later date.) Although MEES and EPCs are closely related this consultation concerns EPCs primarily and DECs secondarily. For example whilst existing exemptions to MEES may continue, exemptions from the requirement for an EPC will most likely change. A key difference here is that exemptions under MEES are linked to a specific landlord and property (which means if a new landlord holds the property, a new re-registration is required). EPCs however are linked to the property itself.
		+
		+	Some key changes being considered also include changes to the requirements for DECs aswell as non-domestic EPCs:
		+
		+	* Headline EPC metrics to cover fabric efficiency, heating system, readiness to smart tech and energy cost with others metrics secondary. DECs remain as are with a carbon focus, perhaps with other metrics added later. Possible future EPC metrics; climate resilience, health and wellbeing, biodiversity, water efficiency.
		+	* Changing EPC requirement from 10 to anything as low a every 2 years. DEC from 10 to 7 years (250-1,000m²) and from 7 to 5 years (1,000m (recommendation report).
		+	* Requirement for private landlords to keep EPC renewed even under same tenancy. For HMOs to require EPCs and EPC requirements for short-term rental properties.
		+	* Whilst existing exemptions under Minimum Energy Efficiency Standards for historic buildings will remain, the EPC requirements will also extend to historic buildings.
		+
		+	See the article Brief notes on proposed changes to EPCs.

	Department of Energy and Climate Change (DECC) research [https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/211054/D13_703672__130605_Display_Energy_Certificates_-_Report_V8_FINAL.pdf Exploring the use of Display Energy Certificates], published in July 2013, suggested that, for organisations that are not engaged in energy management, collecting the information required can lead to a better understanding of energy usage. It can also provide building managers with evidence to help make the case for changes resulting in greater energy efficiency. For organisations that are already engaged in energy reduction, they help confirm which buildings are inefficient or those buildings that are not operating according to their design predictions.

	The purpose of the consultation is to inform updated guidance on display energy certificates and recommendation reports for public buildings. Most significantly, it proposes defining ‘frequently visited by the public’ as: 'daily attendance during days of operation by people for purposes unrelated to their residence, employment, education or training'. This would mean, for example, that a school used only as a school, would not need a display energy certificate because it is not daily attended by people who are neither staff nor pupils. A school that is also used for community functions would require a display energy certificate.
