How it works
Mineral fibre wool is injected into the gap (cavity), between the inner and outer walls of the house. This prevents heat loss through the walls hence reducing the amount of heating required to maintain a comfortable temperature. It increases your home's energy efficiency and may help to reduce your carbon footprint.
Those who are over 70 or on qualifying benefits may be entitled to free home insulation.
Local Authority and Housing Association tenants are not covered by the CERT grant but should contact their landlords to find out what arrangements are in place.
Guarantee
The finished work is guaranteed for 25 years under the Cavity Insulation Guarantee Scheme. Once the work is complete, the installer will register your home under the scheme and you will be sent a certificate of guarantee. This guarantee is transferable from owner to owner so you should keep it and make it available to the new owner at the time of sale.
