For Cavity Wall Insulation you will receive an independent 25 year guarantee from the Cavity Insulation Guarantee Agency. For all types of insulation our members also work to the highest standards of the British Board of Agrément or equivalent regulatory level.

Insulation can reduce your energy bills and carbon footprint and by using a NIA member you can be satisfied that a professional tradesperson will visit your home and undertake an installation to the highest possible standards.

The sooner you make contact the sooner you can benefit from a warmer home and lower fuel bills. There is also a number of Government grants available to lower the costs, especially for those on benefits and those aged 70 or over, speak to an installer member to find out whether you are applicable today.
