What an EPC Certificate Tells You About Your Home
An Energy Performance Certificate (EPC) rates your home energy efficiency from A (most efficient) to G (least efficient). The average UK home has an EPC rating of D with a score of 60 out of 100. EPCs are valid for 10 years and are required when selling or renting a property.
EPC Rating Bands Explained
| Band | Score | Typical Annual Energy Cost | % of UK Homes |
|---|---|---|---|
| A | 92-100 | Under £500 | 1% |
| B | 81-91 | £500-£800 | 4% |
| C | 69-80 | £800-£1,200 | 29% |
| D | 55-68 | £1,200-£1,800 | 42% |
| E | 39-54 | £1,800-£2,400 | 18% |
| F | 21-38 | £2,400-£3,000 | 4% |
| G | 1-20 | Over £3,000 | 2% |
Understanding the Recommendations Page
Page two of your EPC lists specific improvements ranked by cost-effectiveness. Each recommendation shows the estimated cost, potential rating improvement, and indicative savings. The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing.
How EPC Ratings Affect Property Value
Research by the Department for Energy Security and Net Zero shows that improving an EPC rating by one band increases property value by approximately 1-3%. Moving from band D to C adds an estimated £5,000-£15,000 to the average UK property value. Minimum EPC requirements for rental properties will tighten, making improvements essential for landlords.
Getting an EPC Assessment
An EPC assessment costs £60-£120 and takes 45-90 minutes. The assessor examines your walls, roof, windows, heating system, and lighting. Find an accredited assessor through the Elmhurst Energy, Stroma, or Quidos certification bodies. Your assessment feeds into the national EPC register accessible at epcregister.com.
