Do I have cavity walls?

Cavity walls were not a common feature in most homes until the early 1930s, so knowing the date your house was built is a good indicator. If your house was built after 1930, it is likely that your home has cavity walls.

If you are still unsure, check the thickness of your wall by measuring the width near a window or door. If the wall is wider than 260mm, it is likely that your home features cavity walls and may be eligible to add insulation.

Is my house eligible for cavity wall insulation?

If you are confident that your home has a cavity wall, then it is likely that you will be eligible for insulation to be added to your home. Properties that are less than 10 years old will most likely already have cavity wall insulation already installed. Even if your property was built with some insulation in it you could still benefit from a top-up. Most new houses are built with just enough insulation to meet the building regulations and are often compatible for a top-up.

Your home will usually be suitable for cavity wall insulation if:

  • Walls currently have unfilled cavities
  • Cavities are at least 50mm in width
  • Brickwork is in general good condition.

Installation Process for Cavity Wall Insulation

Cavity wall insulation takes anything up to half a day to install, and in most cases is completed through external walls only. Your installation expert from Wise Energy will drill small holes at one metre intervals across the outside wall to access the cavity.

Using specialist equipment, insulation is then inserted into the wall. Once finished and the whole wall has been filled, your installer will refill the holes in the wall, leaving your property with no visible changes.
