Loft Insulation

A quarter of heat is lost through the roof in an uninsulated home. Insulating your loft, attic or flat roof is a simple and effective way to reduce heat loss and reduce your heating bills. Loft insulation is effective for at least 40 years and it should pay for itself many times over.

The recommended depth of blanket-style insulation (glass or mineral wool) for a loft is 250 mm to 270 mm. If you already have insulation but it was installed some time ago, it’s worth checking the depth. Only a few years ago the recommended depth of insulation was 200 mm, and before that it was as low as 100 mm.

If your loft is easy to access and has no damp or condensation problems it should be easy to insulate. If access is easy and your loft joists are regular, you can use rolls of mineral wool insulation. The first layer is laid between the joists – the horizontal beams that make up the floor of the loft. Another layer is laid at right-angles to cover the joists and make the insulation up to the required depth.

Loft Insulation - Typical Savings

A detached house could achieve around £240 per year in savings, and a semi-detached property could save you £140 per year - similar to the savings in a mid-terrace. Bungalow owners can expect to save around £195 per year. Installation costs are low, and subsidies may be available. As you can see from the nearby table, CO2 savings are huge across the board.

Information is taken from Energy Savings Trust. Estimates based on insulating a gas-heated home with either a totally uninsulated loft, or topping up existing insulation from 120 mm to 270 mm. (The recommended depth for mineral wool insulation is 270mm but other materials need different depths).

*Average unsubsidised professional installation costs, although these will vary. Figures are based on fuel prices as of March 2016.
