While much of the public debate around EPCs focuses on residential properties, commercial buildings face their own set of energy performance requirements — and the stakes are high. Non-compliance can result in significant fines and, in some cases, an inability to let the property at all.
When Is a Commercial EPC Required?
A commercial EPC is required whenever a non-domestic building is constructed, sold, or let. This applies to offices, retail units, warehouses, factories, hotels, and most other commercial property types. The certificate must be produced by an accredited Non-Domestic Energy Assessor (NDEA) and is valid for 10 years. It must be made available to prospective buyers or tenants at the earliest opportunity — failure to do so can result in a penalty of up to £5,000.
MEES: Minimum Energy Efficiency Standards for Commercial Property
The Minimum Energy Efficiency Standards (MEES) regulations apply to commercial as well as residential properties. Since April 2023, it has been unlawful to continue letting a commercial property with an EPC rating below E, even under an existing lease. The government has proposed tightening this to a minimum of B by 2030, though this timeline has been subject to consultation and revision. Landlords with commercial stock rated C, D, or E should begin planning improvement works now.
Exemptions and the PRS Exemptions Register
There are limited exemptions available where achieving the minimum EPC rating is not technically feasible or cost-effective. These include situations where all relevant energy efficiency improvements have been made but the property still cannot reach the required rating, where a third party (such as a tenant or planning authority) refuses consent for the works, or where the property has recently been purchased and the landlord needs time to carry out improvements. Exemptions must be registered on the PRS Exemptions Register and are typically valid for 5 years.
Display Energy Certificates (DECs)
Public buildings with a floor area over 250 square metres that are frequently visited by the public are required to display a Display Energy Certificate (DEC) — a separate document from the EPC that shows the actual energy consumption of the building based on meter readings. DECs must be renewed annually for buildings over 1,000 square metres and every 10 years for smaller buildings. An accompanying Advisory Report must also be produced.
