Accredited EPC Assessors UK

An Energy Performance Certificate (EPC) rates your home’s energy performance on a scale from A (most efficient) to G (least efficient). It’s similar to the energy label on household appliances. The EPC is based on the home’s structure, heating system, ventilation, and renewable energy sources. An EPC certificate is valid for 10 years and is legally required when selling or renting a property in the UK.

An EPC certificate is legally required when selling or renting a property in the UK. You may also want an EPC assessment before carrying out energy upgrades like insulation, heat pumps, or solar panels, as it helps identify which improvements will have the biggest impact on your rating. An EPC rating of D or above is often required for rental properties.

A typical EPC assessment for a standard 3-bed semi-detached house costs £60–£120 including VAT. Larger or more complex homes may cost more. The assessment usually takes 1–2 hours on-site. The assessor measures the home, inspects insulation, windows, heating systems, and any renewables. The fee covers the on-site survey, data entry using RdSAP methodology, and the official EPC certificate.

All EPC assessors must be accredited by an approved accreditation scheme. Check that your assessor is accredited before booking. Compare quotes from 2–3 assessors in your area. A good assessor will ask about your home’s construction year, any upgrades you’ve done, and whether you have documentation for insulation or heating systems. They should also be able to advise on the most cost-effective upgrades to improve your rating.
