External Wall Insulation
Fully funded insulation upgrade.
Homes with solid external walls lose a massive amount of heat — up to 35% or more. External Wall Insulation (EWI) wraps your home in a thermal shield, improving warmth, reducing energy bills, and even refreshing your property’s appearance.
- Full survey and suitability check
- Thermal insulation boards applied to exterior walls
- Reinforced render or weatherproof finish
- Colour-matched coatings or brick-effect finish


What is external wall insulation?
EWI involves fixing insulation boards to the outside of your property, then covering them with a weatherproof finish like render or cladding — improving both performance and appearance.
Is planning permission required?
Not usually, but if your property is listed or in a conservation area, we’ll handle any necessary permissions or advise accordingly.
Will it change how my house looks?
Yes — but in a good way. You’ll get a smooth, clean render finish, with colour options available. Brick-effect finishes are also possible.
How long does it take to install?
Depending on your property size, most installations are completed within 5–10 working days, including curing and finishing.
