Improving your Energy Performance Certificate (EPC) rating doesn’t have to be a lengthy or expensive process. Even small changes can significantly boost your home’s energy efficiency, reduce bills, and enhance comfort. Whether your property currently sits at a G or E rating, there are proven strategies to help you climb the ladder toward an A rating.

1. Upgrade Insulation

Loft & Wall Insulation:
Poorly insulated lofts, walls, and floors are major contributors to low EPC ratings. Quick fixes include:

  • Adding loft insulation boards or rolls

  • Installing cavity wall insulation

  • Using insulated underlays for floors

Our EPC Assessors London can inspect and advise on insulation gaps affecting your rating.

2. Seal Draughts Around Windows and Doors

Gaps and leaks allow warm air to escape and cold air to enter. Effective solutions:

  • Install draught excluders on doors

  • Replace or repair worn window seals

  • Check and adjust window frames for alignment

Small improvements like these can raise your EPC score quickly without major construction.

3. Upgrade Heating Systems

Modern, energy-efficient boilers or heat pumps significantly impact your EPC:

  • Replace old boilers with A-rated condensing boilers

  • Install smart thermostats and timers

  • Ensure radiators and pipework are fully insulated

4. Install Energy-Efficient Lighting

Replacing traditional bulbs with LEDs is a simple, low-cost improvement. EPC assessors account for:

  • Lighting type in living spaces

  • Efficiency of lighting in communal areas

  • Energy consumption patterns

Even a small switch to LED lighting throughout your home can contribute points toward your EPC.

5. Consider Renewable Energy Solutions

Adding solar panels, solar water heating, or heat pumps can boost efficiency. While they may not dramatically change the rating alone, they complement other measures:

  • Reduce carbon emissions

  • Lower energy bills

  • Support long-term EPC improvement

6. Maintain and Upgrade Windows

  • Double or triple glazing improves insulation

  • Low-emissivity (Low-E) glass reduces heat loss

  • Properly fitted frames prevent draughts

Combining these upgrades with insulation ensures maximum impact on your EPC.

7. Small Quick Wins

Even minor adjustments help:

  • Lagging hot water tanks and pipes

  • Draught-proofing loft hatches

  • Switching to low-flow taps and showerheads

These steps are cost-effective ways to push your rating toward B or A.

Why Professional EPC Assessment is Crucial

An accredited Domestic Energy Assessor (DEA) identifies hidden energy losses, advises on priority improvements, and ensures that upgrades contribute to a higher rating.
