We are working with the Government to make homes across Great Britain warmer. Find out if you're eligible for free or subsidised cavity wall and loft insulation[1], don't miss out.

Properties built from 1st January 1983 should already have cavity wall insulation, and any property built from 1st January 1991 should not need loft insulation.

Did you know:

  • In an uninsulated home up to a third of your heat is lost through the roof.[2]
  • Cavity wall insulation could save you up to £145[3] a year on your energy bills.
  • Loft insulation could save you up to £150[3] a year on your energy bills.
  • Loft insulation is effective for at least 40 years.[2]
  • The installation only takes a few hours and we will tidy up after.
