EPC (Energy Performance Certificate)
A certificate rating a property's energy efficiency from A (most efficient) to G (least efficient), legally required for lettings and sales.
An Energy Performance Certificate (EPC) rates a property's energy efficiency on a scale from A (most efficient) to G (least efficient). It is a legal requirement for any property being sold, let, or built in the UK.
Current Requirements for Landlords
- You must have a valid EPC before marketing a property to let
- EPCs are valid for 10 years
- The Minimum Energy Efficiency Standard (MEES) currently requires a rating of E or above to let a property
Upcoming Changes (2028)
The UK Government has proposed raising the minimum EPC requirement for rental properties to C or above from 2028 for new tenancies and 2030 for existing tenancies. This could require significant investment in insulation, heating, glazing, or renewable energy.
Cost Implications
Upgrading from an E to a C rating can cost anywhere from £5,000 to £20,000+ depending on the property. Common improvement measures include:
- Loft and cavity wall insulation
- Double or triple glazing
- Upgraded boiler or heat pump installation
- Smart heating controls
- Solar panels
Impact on Property Values
Properties with higher EPC ratings tend to command higher rents and sale prices. Some mortgage lenders also offer preferential rates for energy-efficient properties (so-called "green mortgages").
