Energy Performance Certificate

An Energy Performance Certificate (EPC) is a formal assessment of a building's energy efficiency, showing a rating and recommended measures to improve performance. If you are selling or letting a property in the UK, you will typically need a valid EPC, and it is also useful for understanding heating costs, insulation performance and where upgrades will make the biggest difference. TradeSupermarket helps you find vetted, local EPC assessors who can carry out an on-site survey and lodge your certificate on the official EPC register. Whether you need a domestic EPC for a flat or house, or a non-domestic EPC for a commercial unit, you can compare professionals by availability, reviews, and the accreditations that demonstrate they are qualified to assess and issue EPCs. A good EPC service is more than a quick visit: the assessor should explain what they are checking, how the rating is generated, and what improvements are most cost-effective for your property type. For landlords, an EPC can also support broader compliance planning, such as budgeting for insulation upgrades and heating controls. For safety and trust, always use an accredited energy assessor and confirm that your EPC will be lodged correctly. Reputable assessors carry public liability insurance, follow their accreditation scheme's quality processes, and provide clear documentation you can share with buyers, tenants, or letting agents.
