What Is an EPC?
An Energy Performance Certificate (EPC) rates a property's energy efficiency on a scale from A to G, where A is the most efficient and G is the least. It provides a snapshot of how much energy the property uses to heat, light, and ventilate, and gives an estimated annual energy cost based on standardised assumptions.
The certificate is produced following a visit by an accredited Domestic Energy Assessor (DEA), who surveys the property and inputs the data into the government's Standard Assessment Procedure (SAP) methodology to calculate the rating.
The EPC also includes a list of recommended improvements, showing what actions would improve the rating and their estimated cost and saving.
Is an EPC a Legal Requirement for Rental Properties?
Yes. Since 2008, landlords have been required to have a valid EPC in place before marketing a property for rent or sale. Under the current regulations:
- The EPC must be obtained before the property is put on the market
- A copy must be provided to prospective tenants during the marketing process
- A copy must be given to the tenant at the start of the tenancy
- The property must achieve a minimum EPC rating of E — properties rated F or G cannot be let without a valid exemption
How Long Does an EPC Last?
An EPC is valid for 10 years from the date it was issued. You do not necessarily need a new EPC when a new tenancy starts — as long as the existing certificate is still within its 10-year validity period, it remains valid.
However, if you make significant changes to the property that would affect its energy efficiency rating — such as installing new insulation, a new boiler, double glazing, or solar panels — it is worth commissioning a new EPC to reflect the improvements.
What Is the Minimum EPC Rating for Rental Properties?
Currently, properties must achieve a minimum rating of E to be legally let. Properties rated F or G are in breach of the Minimum Energy Efficiency Standards (MEES) regulations and cannot be let without a valid exemption.
Exemptions exist for situations where the cost of improvements would exceed £3,500 (including any third-party funding available), where a listed building's character would be unacceptably altered, or where a third party such as a tenant or freeholder refuses consent for the works.
What About the Proposed Upgrade to EPC C?
The government has for some time proposed raising the minimum rating from E to C. The most recent proposals suggested:
- C rating by 2028 for new tenancies
- C rating by 2030 for all existing tenancies
These dates have shifted more than once, and the policy has not yet been enacted into law. However, the direction of travel is clear — landlords with properties currently rated D or below should be planning for how they will improve their EPC rating over the coming years.
What Are the Penalties for Non-Compliance?
- Letting a property without a valid EPC: penalty of up to £5,000
- Letting a property below the minimum EPC rating (without a valid exemption): penalty of up to £5,000 per breach
How Can I Improve My Property's EPC Rating?
The most effective improvements vary depending on the property's current construction and systems, but common actions that improve EPC ratings include:
- Loft insulation — one of the cheapest and most effective measures
- Cavity wall insulation — significant impact on heat loss in properties with cavity walls
- Solid wall insulation — more expensive but important for older solid-walled properties
- Double or triple glazing — reduces heat loss through windows
- New energy-efficient boiler — upgrading from an old G-rated boiler to a modern A-rated condensing boiler
- Smart heating controls — thermostatic radiator valves, programmer, and room thermostat
- LED lighting — replacing halogen or incandescent fittings
- Solar panels — can significantly improve the SAP score, particularly when combined with a battery
- Heat pump — the most significant improvement possible for many properties
Your existing EPC will include a list of recommended improvements specific to your property, with estimated costs and potential savings. This is a good starting point for planning works.
