FAQ's - External Wall Insulation
If you want to save money on energy bills, external wall insulation is a great option. It adds an extra layer to the outside of your walls. This means you would use less energy to heat or cool your home, which saves you money. A three-bedroom semi-detached home could save around £290 a year with external wall insulation.

How does external wall insulation work?
External wall insulation acts as a cosy blanket for your home. It helps keep your home warm in winter and cool in summer, so you don't need to use as much energy. It's especially useful for homes with solid walls.
To install it, your gutters and drainpipes are carefully taken off. Special insulation materials like mineral wool, PIR, XPS or wood fibre are then added to the outside of your home. Once installed, your walls get a new smooth layer of render, or an imitation brick (brick slip) to make them look fresh. Your window sills might be adjusted, and gutters and drainpipes will be put back in place.
What does external wall insulation look like and where does it fit in your house?
This special material can be fluffy like wool, made from wood, or a type of plastic. It might look like big flat panels or sheets.
The insulation is put on the outside of your house, but the installers will make everything look new again. This includes rendering the outside wall. You won’t be able to see the insulation.
