Save money on your energy bills by making your home more energy efficient with the Great British Insulation Scheme.

Cavity wall insulation support

A third of heat lost in an uninsulated home escapes through the walls. By properly insulating cavity walls you will save energy and lower your heating bill.

This is done by injecting special materials into the cavity from the outside. Holes are drilled through the exterior walls and insulation – normally mineral wool or polystyrene beads or foam – is injected and then sealed with cement.

This procedure isn’t suitable for all properties. Most homes built between 1920 and 1990 have a gap between internal and external walls. Filling the cavity with insulating material means cold air's kept out, and warm air stays in. If your house is pre-1920 it's likely to have solid walls made of brick or stone that have no cavity and won’t need this type of insulation.

Our insulation comes with an insurance-backed guarantee that lasts for 25 years, giving you peace of mind and saving you money on your future energy bills.

Get help with heating controls

Heating controls can keep your home at a comfortable temperature, without overheating and wasting energy.

By installing and using your heating controls effectively, you can save money on household bills and also lower your carbon emissions. You can upgrade or install heating controls without replacing your boiler.

Homeowners who qualify through low-income for the Great British Insulation Scheme might be entitled to have heating controls included in their insulation support.
