Free cavity wall insulation

Cavity wall insulation acts like a giant blanket around your house, preventing this heat loss. Getting your walls insulated will save you money, reduce your carbon footprint and prevent condensation on your interior walls.

Most houses built after the 1920′s have a two-layer external wall with a small air gap inside — these are called cavity walls. If your house has empty cavities, we can fill them with insulation material. This makes your home more energy efficient.

How is the insulation installed?

Retro-fitting cavity wall insulation is surprisingly simple. There’s no need to tear down any walls or carry out any heavy construction work — all we need to do is drill a few small holes and pump the insulation in. The entire process takes around two hours and you will feel the benefits immediately.

Do I qualify for a grant?

At the moment, all UK households are eligible for free cavity wall insulation. You don’t have to be on benefits and it doesn’t matter where you live.

If your home is suitable, we will access the funding and carry out the work. It is absolutely free.

How much money can I save?

According to figures from the Energy Saving Trust, you could save anywhere from £95 to £250 per year. The exact amount depends on the size and type of your property.
