If you have a problem with your insulation

If you have any problems with your system, get in touch with your installer to alert them as soon as possible. If they do not resolve the problem please check if your installation is covered by guarantee. The Cavity Insulation Guarantee Agency provides independent 25 year guarantees for Cavity Wall Insulation fitted by registered installers in the UK and Channel islands. The Solid Wall Insulation Guarantee Agency (SWIGA) has been established to provide householders and landlords with an independent, uniform and dependable guarantee covering professionally installed External solid wall insulation solutions.
