EPC (Energy Performance Certificate)
The A–G energy grade every UK home needs when it's sold or let — a combined measure of insulation, heating and running cost.
What an EPC actually contains
- Overall rating, A to G
- Current and potential scores out of 100
- Recommended improvements and their estimated cost/saving
- Estimated energy costs per year
Why it matters more than it used to
Mortgage lenders, buyers and tenants increasingly factor in running costs. Homes rated A–C are pulling ahead on both sale value and rental demand.
What improves an EPC
- Loft insulation
- Cavity-wall insulation
- Double or triple glazing
- Efficient boiler or heat pump
- Solar panels

Indicative market guidance — not a regulated valuation and not financial, tax or legal advice. Use a RICS-qualified surveyor for mortgage, insurance or probate purposes.
How long is an EPC valid?
10 years. You can reuse an in-date EPC when you come to re-sell or re-let.
Are there minimum EPC ratings for landlords?
Yes. Rental properties in England and Wales must have an EPC of E or better to be let under current Minimum Energy Efficiency Standards. Proposals to raise the minimum to C have been discussed repeatedly — check current requirements before letting.
How much does an EPC cost?
Typically £60–£120, from an accredited domestic energy assessor.
