CIGA is an independent agency with its own secretariat that provides independent 25 year Guarantee covering cavity wall insulation. It is governed by a council of "System Designers" (who supply the insulation material) and registered installers, with support from trade associations and Government bodies.

Before installation begins, a CIGA registered installer will carry out a pre-installation assessment to ensure that the property is suitable for Cavity Wall Insulation. The installation of the insulation will then be completed at a mutually convenient time according to stringent technical standards laid down by CIGA.

Once the work is finished and final payment has been received the installer will apply to CIGA for a Guarantee, and a certificate will be sent directly to you. The Guarantee should be kept safely, as it may need to be produced in the event of a claim or if you sell the property, since the Guarantee is also available to subsequent owners of the property.

The CIGA Guarantee covers defects in materials or workmanship, and in the event of a problem CIGA's technical department is there to help.
