Improving your Energy Performance Certificate (EPC) doesn’t always require major renovations or professional contractors. Many simple, do-it-yourself (DIY) fixes can enhance energy efficiency, reduce bills, and even increase your EPC rating.

Learn more about our expert services on our About Us page.

1. Draught-Proofing Doors and Windows

One of the easiest DIY fixes:

  • Install draught excluders or weather stripping

  • Seal gaps around window frames and skirting boards

  • Check loft hatches for air leaks

Impact: Reduces heat loss and increases EPC points.

2. Lag Hot Water Tanks and Pipes

Uninsulated hot water tanks and pipes waste energy:

  • Fit a hot water tank jacket

  • Insulate exposed pipes in lofts, basements, or crawl spaces

Impact: Keeps water hotter for longer and reduces energy bills.

3. Upgrade Lighting to LEDs

Replacing traditional bulbs with energy-efficient LEDs:

  • Lowers electricity usage

  • Reduces overall energy demand in your home

  • Quick and cost-effective upgrade

Impact: Small EPC improvement but noticeable savings over time.

4. Minor Loft and Roof Fixes

Even without full insulation:

  • Seal gaps around loft hatches or access panels

  • Ensure recessed lights are insulated or fitted with covers

  • Patch small insulation gaps

Impact: Prevents heat loss and improves EPC scores incrementally.

5. Smart Heating Controls

Small adjustments to heating systems can improve efficiency:

  • Install programmable thermostats

  • Use smart heating apps for scheduling

  • Check radiator valves and balance heating zones

Impact: Reduces wasted energy and contributes to EPC improvement.

6. Check and Maintain Windows

  • Clean and lubricate window seals for proper closure

  • Replace any worn gaskets or broken locks

  • Minor adjustments can reduce draughts

Impact: Improves energy efficiency with minimal effort.

Why DIY Fixes Matter

While DIY improvements may not replace major upgrades like insulation or heating replacement, they:

  • Offer immediate energy savings

  • Are affordable and easy

  • Can increase your EPC rating before a formal assessment

Professional EPC Assessment

Even small DIY upgrades should be verified by a certified Domestic Energy Assessor (DEA) to:

  • Ensure accurate EPC rating

  • Prioritise further improvements for maximum impact

  • Comply with legal requirements for rental or sale
