Cavity wall insulation is an essential part of modern building construction and a growing requirement as an upgrade in older housing stock.
Buildings without adequate levels of insulation can lose up to 35% heat loss through the walls alone, resulting in a 25% increase in energy costs.

At Hillserve, we install over 20,000 cavity wall installations per year. And this is growing.

This experience and expertise makes us the ideal contract partner for a wide range of main contractors as well as social housing providers, utility companies and local authorities.

The insulation products we install is supplied by leading UK manufacturers and all our work is carried out on site by our own highly trained installers. Whether they install blown wool or mineral wool insulation batts, all our work carries a 25 year CIGA Guarantee.
