Well insulated homes need less energy to heat up and stay warmer for longer. By reducing the amount of heat lost through the walls or roof, you could lower your energy bills too.
Once you've covered your initial installation cost, solar panels could help you to significantly reduce your electricity bills and provide a source of more sustainable energy.
If your home is well insulated and you have the outdoor space, swapping a traditional gas boiler for a heat pump could help you to lower your energy costs and create a home that's more sustainable too.
A smart meter can help you understand how you're using energy in your home, which will let you identify opportunities to be more energy efficient. It will also submit gas and electricity meter readings automatically, saving you time.
Retrofitting means updating your home with energy saving improvements. From energy efficient light bulbs to solar panels, spending some money up front could help you reduce your energy bills and create a more sustainable home.
