To help you improve your EPC rating, here are some simple, affordable steps you can take.
1. Install LED Light Bulbs. Cost: Very low (£1–£5 per bulb)
2. Draught Proofing. Cost: £20–£100 depending on the size of the property
3. Add/Improve Loft Insulation. Cost: £100–£300
Loft insulation is one of the most cost-effective ways to improve energy efficiency, and it’s especially impactful if the property is previously under-insulated (this is typically less than 270mm of insulation).
4. Hot Water Tank Jacket. Cost: £20
Drastically reduces heat loss from uninsulated hot water cylinders.
5. Install Thermostatic Controls. Cost: ~£100–£200 (however, smart thermostats can cost more)
6. Pipe Insulation . Cost: £5–£20
It helps retain heat in hot water pipes, especially around boilers and airing cupboards. It's a small gain, but very cheap.
7. Service Your Boiler. Cost: £50–£100
8 . Add insulation Declarations. Cost: Free (just admin work)
If you've added insulation (walls, loft, etc.) but it's not reflected in your current EPC assessment, submit documentation to the assessor, as missing data will default to poor efficiency and bring down your property’s rating.
