Is having cavity wall insulation worth it?

 14th Apr 2022

If your house was built after the 1920s, you may have cavity walls. This is where there are two brick walls with a gap in the middle.

Although they’re commonly found in homes, they’re actually one of the leading causes of energy inefficiency in domestic properties. In fact, they are often responsible for up to ⅓ of heat loss in uninsulated houses.

The more heat loss that you experience in the house, the more energy you’ll have to use heating your space to keep you and your family warm and comfortable – which can lead to significant increases in your monthly energy bills.

To avoid this heat loss and keep your energy bills down, one of the simplest things you can do is pay a professional to install cavity wall insulation.

How does cavity wall insulation work?

A specialist approved contractor can easily install cavity wall insulation with minimal disruption to your home.

They will simply inject either polystyrene beads, mineral wool or rock wool into the cavity through small, drilled holes. After, the holes will be filled in with cement mortar.

How much does cavity wall insulation cost?

It will normally cost around £12 per m2 to install cavity wall insulation, which amounts to between £800 and £1200 for the typical three-bedroom property.

What are the benefits of cavity wall insulation?

There are many benefits that come with installing cavity wall insulation, but here are some of the most important.

  1. Reduces your energy bills significantly
