Floor insulation

Insulating the floorboards on the ground floor of your property can save you up to £40 a year on your energy bills.

Most houses will have a solid ground floor made of concrete. This can be insulated by laying rigid insulation boards on top.

Older homes are most likely to have suspended timber floors. If you have air bricks or ventilation bricks on the outside walls of your house, you probably have a suspended timber floor. It is important that you never block these Air Bricks – they ventilate the space under your floor and prevent damp or condensation.

Timber floors can be insulated by lifting the floorboards and laying mineral wool insulation supported by netting between the joists.

A typical installation could cost between £520 to £1,300 depending on your floor type and area.
