What is cavity wall insulation?
Cavity wall insulation fills the gap between your property's inner and outer walls with modern, breathable insulation material. This stops up to 35% of your home's heat from escaping through the walls, immediately making your home warmer and cutting energy bills by up to £200+ per year.
Our professional installation takes just 3-4 hours with minimal disruption. We drill small holes in the outer wall, inject high-quality insulation material, then seal everything perfectly. Most homes built between 1930-1990 are suitable for cavity wall insulation.
Why might you need cavity wall insulation?
If your home has cavity walls and no insulation, it could be leaking a third of its heat.
Cold rooms and bedrooms that never seem to warm up properly
High energy bills every winter despite having the heating on constantly
Your EPC certificate shows 'Cavity Wall – uninsulated' reducing your rating
No signs of previous insulation drilling around your property's exterior walls
Interior walls feel cold to the touch, especially on external-facing walls
