How to Improve Your EPC Score

Enhancing your Energy Performance Certificate (EPC) rating not only lowers energy bills and carbon emissions—it can increase your property’s market value and help meet future legal requirements.

• Switch to LED lighting: More efficient and affordable, with instant EPC benefits.
• Insulate hot water cylinders: A jacket with at least 80mm thickness can cut heat loss and boost your rating.
• Install heating controls: Thermostats, programmers, and TRVs improve efficiency and score.
• Draught-proof windows and doors: A cheap and effective way to reduce energy waste.

• Loft insulation: A major improvement that increases EPC points and cuts heat loss.
• Cavity wall insulation: Ideal for homes built after 1920 with accessible wall cavities.
• Floor insulation: Especially effective for suspended timber floors in older homes.

• Upgrade your boiler: Replacing an old boiler with a modern A-rated condensing model can significantly raise your EPC score.
• Double or triple glazing: Improves thermal performance and adds EPC points.
• Install smart heating controls: Better control means less wasted energy and a stronger rating.

• Solar PV panels: Generate electricity and reduce your property’s carbon footprint.
• Heat pumps: Ground or air source heat pumps are a strong long-term investment in efficiency.

Your current EPC contains a list of tailored recommendations ranked by cost-effectiveness. Following these suggestions is one of the best ways to move up a band quickly and affordably.

Several UK government schemes offer help with insulation, heating systems, and renewable energy installations. These include grants and low-interest loans that make it easier to invest in efficiency improvements.

For older or less efficient homes, a whole-house retrofit—combining airtightness, ventilation, insulation, and heating upgrades—can deliver substantial improvements in comfort and long-term energy savings.
