Easy Ways to Improve Your EPC Rating

Many EPC improvements are simple, affordable, and can make a noticeable difference to your energy rating and running costs.

Quick & Low-Cost Improvements

• Switch to LED lighting throughout the property

• Fit a smart thermostat or heating controls (room thermostat, programmer, TRVs)

• Draught-proof doors, windows, and loft hatches

• Lag hot water pipes and fit a hot water cylinder jacket (if applicable)

• Seal unused chimneys with a removable draught excluder

Insulation Improvements

• Top up loft insulation to the recommended depth (around 270mm)

• Cavity wall insulation (where suitable)

• Insulate floors (especially suspended timber floors)

Heating & Hot Water

• Upgrade an old boiler to a modern, efficient condensing boiler

• Install thermostatic radiator valves (TRVs) on radiators

• Improve heating controls (time and temperature zoning)

Windows & Doors

• Upgrade to double or triple glazing

• Add secondary glazing where replacement isn’t possible

• Replace single-glazed doors or add draught-proofing

Renewable & Longer-Term Options

• Solar PV panels

• Solar hot water systems

• Heat pumps (air source or ground source)

  
  

Keep the Paperwork

Always keep certificates, invoices, and installation details. These help ensure any upgrades are properly reflected in your EPC rating. These could be for windows, insulation, solar panels or building control.
