To see how efficient your home is, you can enter your address at SimpleEnergyAdvice and see your Energy Performance Certificate (EPC).
Your EPC gives your home a rating based on how efficient it is to heat and power. Fundamentally, heat escapes less in a more efficient home, which means you use less energy and reduces your bill.
If you own your home, there are loads of things you can do to improve your rating. And the place to start is knowing how efficient your home is now. It will guide your decisions about home improvements such as insulation, double glazing and new boilers.
On the other hand, if you rent, your landlord must legally provide you with the EPC for the property. Furthermore, it must be a rating of E or above. And in 2025 this jumps up to a rating of C or above. The good news is that this should mean tenants benefit from living in a more energy-efficient home, and the planet is healthier. However, be prepared to see landlords add the extra cost to rent. Ultimately, it will likely be tenants picking up the bill.
