Guide: Improve your property EPC rating

1. Top up loft insulation

The simplest way to improve your EPC rating is to ensure your loft insulation is at least 270mm thick. Good loft insulation will reduce the energy that can escape through the roof.

2. Add cavity wall insulation

Cavity wall insulation is suitable for properties that have been built with a gap between two layers of brick. Insulation can be blown into the gap from the outside of your property through holes drilled in the wall. These holes are later filled to match your brickwork. This is an easy and relatively cheap way to improve your EPC rating.

3. Replace an old boiler

An old and inefficient boiler will dramatically reduce your EPC score. Replacing it with an energy-efficient one is costly but will massively improve your rating. Add an intelligent thermostat and thermostatic radiator valves, and you could gain even more EPC points.

4. Install double glazing

Double glazing doesn’t add as many points as loft and wall insulation. But if your property isn’t already double glazed, installing it will boost your score by up to ten points.

Triple glazing is becoming more mainstream and will further reduce the amount of heat that escapes through your windows. However, if you already have double glazing, you will gain only a minimal improvement to your EPC rating by upgrading it to triple glazing.

5. Use renewable energy

Adding solar panels or ground source heat pumps to your home is another way to improve the energy rating of your property and save money on your energy bills.

6. Install energy-efficient lighting

Replacing your old traditional incandescent bulbs with halogen bulbs, compact fluorescent lamps or LED bulbs is a quick and easy way to score a few extra points on your EPC. Although their initial cost is higher, you save money because these types of bulbs use much less energy.
