What is external wall insulation?
If your home was built before the 1920s, it's likely the external walls are solid walls rather than cavity walls.
- Solid walls have no gap, so they can’t be filled with cavity wall insulation.
- Cavity walls are made of two layers with a gap or ‘cavity’ between them.
Solid walls can be insulated by adding an insulating layer, either on the inside or the outside, to prevent heat escaping through your walls while keeping the cold out.
This will cost more than insulating a cavity wall but the savings on your heating bills will be bigger too.
How can I tell if I have a solid wall?
Solid walls come in many different forms but there are some common ways to tell if your wall is solid or not:
- was built before 1920
- has walls less than 260mm thick
- has brickwork like below
You might need to have planning permission before installing solid wall insulation — check with your local council before starting.
Why is external wall insulation a good idea?
A cold wall will take heat away from anything around it. Solid wall insulation adds a thermally protective layer to the outside of your home.
What our customers say
Before we were spending £25 to £30 per week on our gas and electricity during the winter and we had to have our heating on day and night. But now, the exterior wall insulation that has been installed keeps the cold out and the warmth in and we're spending much less.
Before the external wall insulation we used to have our thermostat on 25 degrees most of the winter but now we only have it on 15 degrees, any higher and the property gets too warm. Also we are definitely saving money on bills.
How can I fund my external wall 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.
