Loft Insulation
In an uninsulated home a quarter of your heat is lost through the roof. InsulatinIg your loft is a simple and effective way to reduce your heating bills.
How loft insulation works
It acts as a blanket, trapping heat rising from the house below. You should also consider lagging your pipes at the same time for optimum efficiency.
The savings
If you currently have no loft insulation and you install the recommended 270mm depth you could save around £205 a year on your heating bills and around 1 tonne of carbon dioxide (CO 2) per year.
How it is installed
Insulation is simply laid over the floor of the loft, between and then over the joists if they are visible. Protective clothing, gloves and masks should be worn. Care must be taken not to insulate below the cold water tank, if one is present, and not to compress the insulation in tight corners or eaves. Walk boards can then be laid over the joists to provide safe access from the loft hatch to any water tanks (if present).
There are grants and offers available to help you pay for loft insulation.

The installed cost includes an example of subsidy available; the typical unsubsidised installed cost is around £500 for loft insulation to 270mm from either 0mm or 50mm.
The Government, and local authorities sometimes provide grants towards insulating the home.
How the savings add up?
If everyone in the UK topped up their loft insulation to 270mm, over £700m would be saved each year. That's enough money to pay the annual fuel bills of around 550,000 families.
