Without loft insulation, you could be losing as much as 25% of your heating costs through your roof. Insulating your loft is a simple and effective way to reduce your heating bills as well as having cavity wall insulation put in.

That may seem less important when the sun is shining, but when you need the heating to take the chill away, insulation means you retain the daytime warmth better, need the heating less, and pay less to the hungry energy providers!

The ideal thickness for loft insulation is 270mm, which can save up to 25% of your heating costs. If your loft insulation is not this thick you should have yours topped up to this level.
