Loft Insulation

Loft Insulation grants are available to homes with inefficient heating systems (or no heating system), with no requirement to meet any benefit criteria.

If your homes loft insulation is currently 10cm deep or less, your home would benefit from increasing the amount of insulation to current building regulation levels of 27cm or more. As your home loses the majority of it's heat through the roof, fully insulating your loft helps to retain heat in your home, which in turn reduces your fuel bills and amount of carbon emissions produced.Apply for your free insulation grant now whilst funding remains available.

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 is usually available for free with a Help to Heat grant.

To qualify, the existing loft insulation should be no more than 100mm deep and must not be fully covered by loft boards.

Help to Heat allows for loft insulation to be installed as new or existing insulation to be topped up to 250-275mm, subject to the materials used. In addition draught proofing is added to loft hatches and any water tanks and exposed pipes in the loft space are insulated.

Estimates based on insulating a gas-heated home with either a totally uninsulated loft, or topping up existing insulation from 120mm to 270mm. (The recommended depth for mineral wool insulation is 270mm but other materials need different depths). Figures are based on fuel prices as of March 2016. Provided by EnergySavingsTrust.

Pipes, water tank and loft hatch

Insulating between the joists of your loft will keep your house warmer but make the roof space above colder. This means pipes and water tanks in the loft space could be more likely to freeze, so you will need to insulate them. If your water tank is some distance from the loft hatch, you will also need something to walk on for safe access.

The cooler air in your insulated loft could mean that cold draughts come through the loft hatch. To prevent this fit an insulated loft hatch and put strips of draught-excluding material around the hatch edges.
