Improving your EPC rating doesn’t always require major renovations or expensive upgrades. Sometimes, small, targeted changes can deliver significant gains in energy efficiency, reduce your bills, and even increase your property’s value.

For expert guidance and accurate assessments, our EPC Assessors in London can help you identify the most effective quick wins:

1. Draught-Proof Doors and Windows

Small gaps around doors and windows allow heat to escape, creating hidden energy losses. Quick fixes include:

  • Installing draught excluders

  • Sealing window sills and door frames with weatherstrips

  • Checking and sealing gaps around loft hatches

Even minor draught-proofing can improve your EPC rating. Book a professional assessment to ensure all leaks are detected:

2. Upgrade to Energy-Efficient Lighting

Switching from incandescent or halogen bulbs to LED lighting is a low-cost way to improve efficiency. EPC calculations credit low-energy lighting, so this simple change contributes directly to your rating.

3. Install Thermostatic Radiator Valves (TRVs)

TRVs allow you to control temperature in individual rooms, reducing wasted energy and heating costs. Adding TRVs is a quick improvement that is often overlooked in EPC assessments.

4. Check and Optimize Your Boiler Settings

Modern boilers are efficient, but incorrect settings can waste energy. Small adjustments include:

  • Lowering thermostat temperatures slightly

  • Optimising heating schedules

  • Ensuring hot water cylinders are insulated

Professional assessors can check if your boiler and heating controls are optimised for your EPC score:

5. Seal Pipework and Cylinder Jackets

Insulating hot water pipes and adding cylinder jackets reduces heat loss, improving EPC scores with minimal cost and effort.

6. Minor Window Improvements

If full double-glazing isn’t feasible, you can still improve efficiency by:

  • Adding thermal curtains

  • Installing secondary glazing panels

  • Ensuring existing windows are well-sealed

These small steps can reduce heat loss in key areas.

7. Simple Renewable Upgrades

Even small renewable installations can boost your EPC:

  • Solar water heating

  • Small solar PV panels for electricity

  • Micro wind turbines for off-grid efficiency

Providing documentation of these upgrades ensures your EPC assessor credits them correctly:

8. Reduce Thermal Bridging and Air Leaks

Quick inspections can reveal areas where heat escapes due to:

  • Poor insulation at wall junctions

  • Gaps around floors and ceilings

  • Chimney or pipe penetrations

Sealing these areas can result in notable EPC gains. Learn how our assessors identify hidden inefficiencies:
