How to Improve Your EPC Score

Improving your Energy Performance Certificate (EPC) score can increase your property’s value, reduce energy bills, and make your home more appealing to buyers or tenants. Whether you’re a landlord, homeowner, or investor, a better EPC rating helps meet legal standards and supports sustainability.

Your EPC score reflects how energy efficient your property is, rated from A (most efficient) to G (least efficient). The score is based on insulation, heating systems, windows, lighting, and energy use. A higher score means lower costs and emissions.

• Lower energy bills
• Increased property value
• Compliance with rental laws
• Eligibility for green financial products
• Environmental sustainability

1. Upgrade Insulation

• Loft insulation: Add up to 270mm for better retention.
• Cavity wall insulation: Helps trap heat inside.
• Floor insulation: Useful for older suspended floors.

2. Install a More Efficient Boiler

Replacing an old G-rated boiler with an A-rated condensing model can improve your EPC by one or two bands.

3. Use Smart Heating Controls

Install smart thermostats and radiator valves to better manage your energy usage.

4. Switch to LED Lighting

Swap out inefficient lighting for LED bulbs to improve your EPC by a few points quickly and affordably.

5. Improve Windows and Doors

Upgrade to double or triple glazing and ensure seals are tight to prevent heat loss.

6. Install Renewable Energy Systems

Solar panels, heat pumps, and solar hot water systems significantly boost your EPC score.

7. Draught Proofing

Seal gaps around doors, windows, and floors to keep heat in and cold out.

8. Upgrade Hot Water Systems

Use a modern cylinder with a thermostat and insulating jacket to retain heat better.
