An EPC is a starting point for choosing improvements, not a shopping list. This guide shows how to check the current rating, prioritise work that reduces heat loss and record the result for the next assessment.
Plan energy improvements in order
Insulation and draught reduction
Thermostats and heating controls
Efficient heating and hot water
Suitable renewable technology
Read the current certificate
Check the current and potential rating, expiry date and recommended measures. Confirm that the certificate describes the property accurately. A new assessment may be useful after substantial improvements or changes to the building.
Confirm the minimum standard
A domestic private rented property covered by the Minimum Energy Efficiency Standard normally cannot be let with an F or G rating unless a valid exemption is registered. Check the official guidance before relying on an exemption.
Plan improvements in the right order
Start with the building fabric and obvious heat loss before replacing major equipment. Consider insulation, draught reduction, heating controls, an efficient heating system, hot water insulation and suitable renewable technology.
- Loft and wall insulation
- Draught reduction and glazing
- Heating controls
- Efficient heating and hot water
- Suitable low-carbon technology
Record the work and reassess
Keep quotes, invoices, product details and photographs. Arrange a new certificate where needed and provide the valid certificate when marketing or granting a tenancy. Review future government standards before planning long-term investment.
