How to Improve Your EPC Rating

A higher EPC rating lowers bills, lifts property value and meets letting and sale expectations. Most homes can move up at least one band with the right measures.

Start with the cheap wins

LED lighting, draught-proofing and a smart thermostat are low-cost first steps that the assessment rewards.

Tackle fabric and heating

Loft and wall insulation plus a modern, efficient heating system (or a heat pump) deliver the biggest rating jumps.

Book a proper assessment

A qualified Domestic Energy Assessor surveys the property and models improvements; ask which measures would lift the band before you commit spend.

Sequence for value

Insulate first, then upgrade the heat source — this avoids oversizing a boiler or heat pump and keeps costs down.
