External wall insulation

Roughly 35% of household heat escapes through the walls if uninsulated.

External wall insulation could save you between £190 and £550 on your annual energy bills.

And you could receive solid wall insulation for free with government funding.

The UK government offers many households solid wall insulation grants to improve energy efficiency and lower energy bills across the board.

Don’t wait around – check now to see if you qualify for the government’s internal and external wall insulation grants.

How external wall insulation works

Whether it’s via the ECO4 scheme or the Great British Insulation scheme, we can install external wall insulation in your home. Cavity wall insulation involves a process of checking your cavity walls, choosing the correct insulation material and then protecting your home.

Here is the process we follow for installing external wall insulation.

1
Insulation material
A layer of insulation material is installed on the external walls of your home. The main insulating component is typically made of expanded polystyrene (EPS). Phenolic boards or mineral wool can also be used.
2
Render
The insulation is then covered with a render or cladding which can be smooth, textured, painted, or finished with brick slips. This step hides the insulation and leaves an aesthetic finish to the exterior of your home.
3
Warmer in winter
Thanks to the external wall insulation, less warm air will leave your home, ensuring the property stays warmer for longer – vital in the winter months.
4
House protection
External wall insulation also helps to reduce condensation on your internal walls, as well as improve the sound resistance and weatherproofing of the property.
