Cavity Wall Insulation

Cavity wall insulation is a system whereby insulating material is injected into the gap (or cavity) between a property’s inner and outer walls. It reduces the amount of heat escaping from your home into the outside world and keeps the warmth inside your home making you warm and cosy when you need to be.

It also works in reverse keeping you cooler in the summer months.

Domestic and General's team of insulation fitters installed cavity wall insulation in over 15,000 homes last year, which means our installation teams are installing insulation in around 40 homes per day around the country.

Homes with cavity wall insulation save, according to The Energy Saving Trust, around £110 per year on their heating bill and prevent around 560kg of CO2 being emitted into the atmosphere.

Furthermore, grants are offered by the Government and energy companies to make cavity wall insulation more affordable. In some cases, you may even be entitled to insulate your home for free.

Features and Benefits

Cavity wall insulation provides a good return on a relatively small investment.

Installed from around £99 for the average three-bed semi detached property, you can expect savings of £110 per year, according to the Energy Savings Trust, on your heating bill meaning it can pay for itself in the first full year after installation. Furthermore, everyone is entitled to some level of non-repayable grant funding towards the cost of cavity wall insulation making it even more cost effective. Some people even qualify for free insulation.

What Else Can I do to Insulate my Home?

Deciding to insulate your cavity walls is a great first step to achieving better energy efficiency for your home and the associated reductions in your heating bills. However, to really capitalise on reductions in heating bills through energy efficiency, you should also consider insulating your loft space too.
