How to Improve Your EPC Rating Before Renting

An Energy Performance Certificate (EPC) rates how energy efficient a property is, from A (most efficient) to G (least efficient).
In the UK, landlords must have an EPC rating of at least E to rent out a property — and proposed future laws may require C or above.
A higher EPC rating can:

• Attract quality tenants
• Reduce tenant energy bills
• Increase property value
• Ensure legal compliance

How to Check Your Current EPC Rating

• Look at your existing EPC (valid for 10 years).
• Search the UK EPC Register online using your postcode.
• Check the recommendations section for improvement ideas.

Cost-Effective Ways to Improve Your EPC Rating

1. Upgrade Lighting to LED Bulbs

LEDs use up to 90% less energy than traditional bulbs and have a longer lifespan.

2. Improve Loft & Wall Insulation

Good insulation stops heat escaping, lowering heating bills and boosting EPC scores.
Tip: Loft insulation is one of the cheapest, high-impact upgrades.

3. Install a More Efficient Boiler

Old boilers waste energy. Consider replacing with a condensing boiler or upgrading to a more efficient heating system.

4. Add Smart Heating Controls

Smart thermostats and heating timers improve efficiency and reduce wasted energy.

5. Draught-Proof Windows & Doors

Cheap draught-proofing strips can prevent heat loss and make a noticeable difference.

6. Upgrade to Double or Triple Glazing

Better glazing reduces heat loss and improves comfort — a strong EPC booster.

7. Use Renewable Energy Where Possible

Solar panels or air-source heat pumps can provide long-term efficiency gains and significantly improve your EPC rating.

EPC Improvement Checklist for Landlords

• Review your current EPC report.
• Prioritise low-cost, high-impact upgrades.
• Keep receipts for all improvements (can boost property value).
• Re-test EPC after major upgrades to confirm your new rating

Final Thoughts

Improving your EPC rating before renting is not just a compliance step — it’s an investment in your property’s value, tenant satisfaction, and long-term savings.
Even small, inexpensive upgrades can push your property into a higher rating bracket and make it stand out in the rental market.
