Cavity Wall Insulation is a simple and effective way to save money on your energy bills. Houses built before the 1990s may not have wall insulation, which can cause heat to escape more quickly through uninsulated walls. However, most types of walls can be insulated in one way or another. If you have a typical house with cavity walls, you could save up to £690 per year in heating bills just from insulating the walls.

What is Cavity Wall Insulation?

Wall Insulation involves filling the gap between your internal and external walls with an insulating material such as mineral wool or polystyrene beads. This helps to keep heat in and reduce your energy bills. Most homes built after 1935 will have cavity walls which can be insulated by drilling a series of holes and pumping in the insulating material.

How to check if your house already has wall insulation?

If your house was built after the mid-1930s, it probably has cavity walls that can be insulated. You can check by measuring your window sills, which should not exceed 10 inches, or by looking at the brick pattern. If your walls are suitable for wall insulation, the bricks will all look the same size.

What are the benefits of wall insulation?

Insulation can help you save money on your energy bills, make your home more comfortable and reduce your carbon footprint. Additionally, Insulation can increase the value of your home and improve the Energy Performance Certificate (EPC) rating.
