home insulation
Heat will always flow from a warm area to a cold one. In winter, the colder it is outside, the faster heat from your home will escape into the surrounding air. Insulating your home correctly is one of the most important energy saving measures you can take to reduce energy consumption.
Having the latest Air source heat pumps or A rated gas boiler is pointless if the heat is going straight up and out of the roof because the loft insulation isn’t up to current standards. The more heat that can be withheld within your home the less the Heat pump / Boiler has to work therefore the less energy it uses.
