An Energy Performance Certificate (EPC) rates a property's energy efficiency on a scale from A (most efficient) to G (least efficient). It's legally required when a property is built, sold or rented.
What it covers
The EPC includes a current energy rating, a potential rating if recommended improvements are made, and a list of recommendations (insulation, heating upgrades, etc.) with estimated costs and savings.
Why it matters
- Running costs: a Band A home costs significantly less to heat than Band F or G
- Rental properties: from 2025 (legislation pending), rental properties may require a minimum EPC rating of C. Landlords with lower-rated properties face restrictions on new tenancies.
- Mortgages: some lenders offer 'green mortgages' with preferential rates for energy-efficient homes
Getting one
EPCs must be conducted by an accredited assessor. They're typically £60–£120 and valid for 10 years. Find accredited assessors at epcregister.com.
