A low EPC (Energy Performance Certificate) rating can impact everything from your property’s rental potential to its resale value—and even your energy bills. But the good news is: improving your EPC rating is not only possible, it can be simple and cost-effective with the right steps.

At EPCrate.co.uk, we’re experienced EPC assessors providing fast, affordable, and compliant certificates across London. Below, we’ll guide you through practical ways to improve your energy efficiency and boost your EPC score.

🔧 1. Upgrade Your Insulation

Poor insulation is one of the main causes of a low EPC rating. Consider upgrading:

  • Loft insulation to at least 270mm

  • Cavity wall insulation where applicable

  • Floor insulation (especially in older properties)

These improvements reduce heat loss and can dramatically improve your rating.

💡 2. Install Energy-Efficient Lighting

Switching all light bulbs to LED or CFL alternatives is one of the quickest and cheapest ways to bump your EPC score. Not only do LEDs consume up to 90% less energy, but they also last much longer.

🌡️ 3. Improve Heating Controls

If your property lacks modern heating controls, you could be wasting energy. Consider:

  • Thermostatic radiator valves (TRVs)

  • Smart thermostats

  • Zoned heating systems

These help you control heat distribution and reduce unnecessary usage.

🔄 4. Replace an Inefficient Boiler

An old, non-condensing boiler is a red flag on any EPC report. Upgrading to a modern A-rated condensing boiler could increase your rating by 1–2 bands—especially when combined with programmable controls.

☀️ 5. Consider Renewable Energy Solutions

While a bigger investment, installing solar panels or air-source heat pumps can offer significant long-term benefits for energy performance. These upgrades are viewed favourably in EPC calculations and may qualify for government incentives.

📉 6. Draught-Proof and Double-Glaze

Simple fixes like draught-proofing windows and doors, sealing gaps, and installing double or triple glazing can also enhance thermal performance.
