Cavity Wall Insulation for UK Homes
One of the most cost-effective upgrades for UK homes: certified cavity fill material injected by accredited operatives, with a full suitability survey, post-installation inspection, and CIGA-backed guarantee.
Cavity Wall Insulation
Seal the Walls
Cavity wall insulation is one of the most cost-effective measures available for UK homes built after 1920. An uninsulated cavity loses a significant proportion of a home's heat through the external walls; insulating it correctly reduces heat loss, lowers energy bills, and improves the property's EPC rating.
Nexura assesses every property before recommending a fill material. We check for existing cavity obstructions, wall ties, moisture exposure, and construction type. Where the cavity is suitable, we inject certified insulation under controlled conditions using accredited equipment. Where it isn't, we specify an alternative: internal wall insulation or external cladding, rather than proceeding with a solution that won't perform.
Our installation teams are fully accredited under PAS 2030 and CIGA-registered. Every job is followed by a post-installation inspection and covered by a 12-month guarantee on workmanship.
