Insulation acts as a resistor tot he transfer of heat. Like a blanket, trapping heat rising from the house below. 

This diagram from the Energy Saving Trust shows the the losses of heat from the typical home. Insulation slows the rate of heat loss, meaning that you need to use less energy to maintain a constant temperature in your home.

The savings

If you currently have no loft insulation and you install the recommended 270mm depth you could save around £110 a year on your heating bills and nearly 1 tonne of CO2 per year.

The following table gives approximate costs, savings and paybacks for loft insulation:

 

How the savings add up

If everyone in the UK topped up their loft insulation to 270mm, £380m would be saved each year. That's enough money to pay the annual fuel bills of over 400,000 families.

Insulating your loft cavity requires safety equipment such as dust mask, 
goggles and overalls.
