  • In 2018 many homes in Scotland are not insulated correctly, which leads to higher heating bills
  • Insulating your roof and walls can save £100’s per year on home energy costs


Cavity Wall Insulation

Cavity Wall Insulation stops heat escaping out through the walls of your home. Around 35% of heat in the average home in Scotland and the UK is lost through the outer walls of the house. Under the current Government Insulation Grants Scheme, hundreds of thousands of Scottish and UK homeowners, landlords and private tenants qualify for a grant for wall insulation.

If your home was built after 1920, it probably has walls  with a gap or cavity between them. Cavity wall insulation fills that gap, keeping the warmth in to save energy. It can also help reduce condensation inside the house if this is a problem on your external walls.

What is wall insulation?

The cavity wall insulation that is installed through the wall insulation grant scheme a man made fibre similar to loft insulation, but finely chopped so as to fit in between your walls. It is moisture proof and cannot pass dampness from your exterior wall to the interior wall via the cavity.

Installing cavity wall insulation is like putting a coat on your house. The insulation keeps the heat in, meaning that you can have your central heating on for less time, or turn in down to a lower level. This costs you less in gas / fuel bills and reduces harmful emissions which are released into the environment. Cavity wall insulation also keeps your home cooler in the summer.

Is cavity wall insulation suitable for your house?

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

  • your external walls are unfilled cavity walls
  • your cavity is at least 50mm wide
  • the masonry is in good condition
  • it is more than ten years old

How much could you save?

By installing cavity wall insulation you can save up to £250.00 per year on fuel bills. These are estimated figures based on insulating a gas-heated, semi-detached home with three bedrooms. If you live in a larger property or have an alternative heating type you will save even more. Energy Savings Trust.
