How much will Cavity Wall Insulation save me?
Around a third of all the heat lost in an un-insulated home is lost through the walls. If you have cavity walls, insulating them will significantly improve the thermal efficiency of your home and it could save you up to £135 a year on your fuel bills.
The cost of cavity wall insulation has never been lower as it is subsidised by the Government. For an average house the cost of installation is about £100 – £350, making the return on investment 1 – 3 years. View the insulation money savings here
