Making your home more energy efficient

Householders' greening guides

Our householders' greening guides offer practical advice to help you:

  • make your home more energy efficient
  • adapt to climate change
  • switch to clean energy

In a typical British home up to a third of heat produced by central heating systems is lost through the roof, walls, floor and windows.

If your property is poorly insulated, this means £1 in every £3 spent on energy is wasted.

You can check how much heat your building is losing with a heat loss map.
