Energy Performance Certificates (EPCs): What You Need to Know in 2025
If you’re a landlord, tenant, or letting agent in 2025, understanding Energy Performance Certificates (EPCs) is more important than ever. With regulatory changes on the horizon and rising energy costs, having a compliant, efficient property isn’t just a legal requirement — it’s a smart investment.
What Is an EPC?
An Energy Performance Certificate is a document that shows how energy efficient a property is. Each EPC includes:
- An energy efficiency rating from A (most efficient) to G (least efficient)
- Estimated energy costs for heating, lighting and hot water
- Environmental impact (CO₂ emissions)
- Recommendations for cost-effective improvements
EPCs are valid for 10 years and must be issued by an accredited Domestic Energy Assessor (DEA).
When Is an EPC Required?
By law, an EPC is required when:
- You let or sell a property
- A new tenancy agreement is signed
- Marketing begins on any residential or commercial property
If you fail to provide an EPC, you could be fined up to £5,000. See the full legal guidance here.
How EPCs Are Calculated
EPCs are calculated using the RdSAP (Reduced Data Standard Assessment Procedure), a government-approved methodology that takes into account:
- Wall, floor, and roof insulation
- Glazing type and draught-proofing
- Type and efficiency of the heating system
- Use of low-energy lighting
- Presence of renewables (solar PV, heat pumps)

Minimum EPC Rating for Rentals
As of 2025, landlords must ensure their rental properties meet a minimum rating of E to be legally let. However, the government has proposed that all new tenancies from 2025 and all existing tenancies from 2028 must have an EPC rating of at least C.
Non-compliance can result in enforcement notices and fines.
How to Improve Your EPC Rating
Improving your EPC rating helps you reduce running costs, futureproof your property, and attract better tenants. Common upgrades include:
- LED lighting throughout
- Loft and cavity wall insulation
- Upgrading to a condensing boiler or heat pump
- Double or triple glazed windows
- Smart thermostats and heating controls
