Cavity Wall Insulation Cost

The benefits of cavity wall insulation are numerous and the cost of having it fitted to your property will be recouped through energy savings over time. In fact, it could make your home more valuable if you ever decide to sell it.

It is also worth mentioning that it is possible to receive financial assistance to pay for the installation of cavity wall insulation as part of the Great British Insulation Scheme. To find out more about what grants are available, enter your postcode here.

Cavity wall insulation cost is generally based on the type of insulation used and the size of your house. For example, the average cost of insulating a bungalow is around PS800, while the cost for a semi-detached or detached property would be double that amount.

There are a number of other factors that affect the cost of having cavity wall insulation installed. For instance, if your property is rendered then this will affect the quote because the walls are harder to work on and more likely to leak from any gaps that need plugging before the insulation can be installed. It is also important to check if your home has adequate ventilation as this will help prevent dampness and condensation issues.

The type of wall insulation will also influence the cost. For example, polystyrene bead insulation is the cheapest form of cavity wall insulation and involves a registered installer blowing small insulating beads into your wall cavities through holes that are then sealed up afterwards. Polyurethane foam is more expensive but is a better quality insulant that can be mould resistant and lasts longer. Mineral wool is the most expensive but is a good choice for those who are environmentally conscious as it can be made from recycled materials.
