What is cavity wall insulation?
Cavity wall insulation is one of the best and most affordable ways to improve your home's energy efficiency.
Houses in the UK mostly have either cavity walls or solid walls:
- Cavity walls are made of two layers with a gap or ‘cavity’ between them. If your home was built after the 1920s, it's likely to have cavity wall
- Solid walls have no gap, so they can’t be filled with cavity wall insulation. If your home was built before the 1920s, it's likely the external walls are solid walls rather than cavity walls
Cavity walls can be insulated by injecting insulation into the cavity from the outside through drill holes in the outside walls. Insulation is usually mineral wool or polystyrene beads, or polyurethane foam. Cavity wall insulation lasts up to 42 years.
For a typical home, cavity wall insulation starts from £2,208(2)
How can I tell if I have a cavity wall?
There are some common ways to tell if your property has a cavity wall:
- It was built after 1920; homes built within the last 40 years almost certainly do
- It has walls more than 260mm thick
- It has brickwork like one of these picture examples
Why is cavity wall insulation a good idea?
Insulating the cavity space between the outside and inside wall adds a barrier to stop the cold from coming in and heat from escaping.

What our customers say
I have noticed a huge difference in the warmth of my home. Before I was having the heating on not just high during the day but also I had to keep it on through the evening during very cold winter nights. This was extremely expensive.

A Complete Guide to Floor Insulation
Cold doesn't just come in through walls, doors and windows, it can come up through the floor too. Insulation can prevent this, make the floor more comfortable to walk on and prevent mould.
