An Energy Performance Certificate (EPC) is a legal requirement for anyone selling, renting, or leasing a property in the UK. In 2026, the rules and expectations for both domestic and commercial EPCs are stricter than ever, making it essential for property owners, landlords, and businesses to understand their obligations.

EPCs measure a property’s energy efficiency, giving a rating from A (most efficient) to G (least efficient), while also estimating running costs, carbon emissions, and potential improvements.

Domestic EPCs: Legal Obligations in 2026

For homes, flats, and apartments, an EPC is required before a property can be:

  • Sold to a new owner

  • Rented to tenants

  • Marketed on property portals

Key updates for 2026:

  • Minimum energy rating requirements have been reinforced under MEES (Minimum Energy Efficiency Standards). Rental properties must be rated E or above, unless exemptions apply.

  • Certificates must be lodged on the official EPC Register.

  • Failure to provide a valid EPC can result in fines and delays in property transactions.

Domestic EPCs also help homeowners:

  • Identify energy-saving opportunities

  • Reduce utility bills

  • Improve property value and marketability

Key updates for 2026:

  • MEES now strictly applies to commercial properties, with financial penalties for non-compliance.
