Does my property qualify for Cavity Wall Insulation?
If your house was built after the 1920s, it is likely to have cavity walls. Older houses are more likely to have solid brick which means the cavity wall insulation cannot be installed. However, on some circumstances we have found and installed Cavity Wall Insulation in properties before the 1900’s.
If you can see the brickwork on the outside of the house, look at the pattern of the bricks.
If the brickwork has been covered, you can also tell by measuring the width of the wall. Examine a window or door on one of your external walls. If a brick wall is more than 260mm thick then it probably has a cavity; a narrower wall is a solid wall.
The external wall of a house is usually made of two layers, with a void in the centre, known as a cavity. Filling the space between the two walls with insulation material is an effective way to prevent the loss of up to 35% of your home’s heat.

Benefits of Cavity Wall Insulation
National Insulations has a network of approved Cavity Wall installers working throughout England and Wales. All installers have access to ECO funding and carry out a free, no-obligation survey of the property.
Our online form will tell you which grant you are likely to qualify for and whether we have an approved installer working in your postcode area. Once you have completed the form, National Insulations will contact you within 48 working hours and arrange an appointment for an accredited installer to visit your property.
The surveyor will then advise if your property qualifies for a grant and will then provide you with documentation that the work is to be carried out for free.
If you are then happy to proceed after the survey, the surveyor will arrange for the work to be completed with the installer.
