Free Insulation Grant

Keep Your Home Warm and Energy Efficient

Cavity wall insulation works by filling the space between your home’s internal and external walls, significantly helping to reduce heat loss. Common materials include urea formaldehyde foam, cellulose, mineral wool, and insulation beads—with most of our trusted cavity wall installers recommending polystyrene beads for their superior performance and long-term benefits.
Installing cavity wall insulation improves thermal comfort year-round—keeping your home warm in winter, cool in summer, and even helping to reduce noise. Best of all, it’s a proven way to enhance energy efficient walls and cut down on your heating costs.
