The EPC Rating Scale
EPC ratings run from A (most efficient) to G (least efficient). Each band corresponds to a range of energy efficiency scores:
| Band | Score | Description |
|---|---|---|
| A | 92–100 | Most efficient — typically new-builds with excellent insulation and renewable energy |
| B | 81–91 | Very efficient — well-insulated with modern heating systems |
| C | 69–80 | Fairly efficient — above average, often post-2000 builds or upgraded older homes |
| D | 55–68 | Average — the most common rating for UK homes |
| E | 39–54 | Below average — older properties with limited insulation |
| F | 21–38 | Poor — significant energy efficiency issues |
| G | 1–20 | Very poor — the least efficient properties |
What Does the Average UK Home Score?
The average UK home currently scores around 69, placing it in the C band. Historically this was lower, but improvements through insulation programmes, boiler upgrades and new building regulations have raised the national average.
Minimum Energy Efficiency Standards (MEES)
Since April 2018, rental properties in England and Wales must have a minimum EPC rating of E. Landlords cannot grant a new tenancy for a property rated F or G unless they have a valid exemption.
The Government has proposed raising this minimum to C by 2030, though this is not yet law.
