The Cavity Insulation Guarantee Agency is an independent body that provides 25 year guarantees for Cavity Wall Insulation fitted by registered installers in the UK and Channel islands. The standard Guarantee covers traditionally constructed residential property, although a CIGA Commercial Guarantee is also available to owners of qualifying non residential property.
The Government regards cavity wall insulation as the most effective energy savings measure that most people can carry out on their homes and a major contributor to reducing emissions of carbon dioxide, the main greenhouse gas. The Cavity Insulation Guarantee Agency was established in 1995 after consultation with the Government’s Energy, Environment and Waste Directorate (a division of DETR) to provide householders with an independent, uniform and dependable guarantee covering defects in materials and workmanship.
Independent research carried out for the Department of the Environment, Transport and the Regions (DETR) has confirmed that cavity wall insulation is a very reliable process. Problems are therefore extremely rare, but if they do occur, CIGA has the expertise to ensure that they are swiftly rectified.
CIGA also operates and administers the Cavity Wall Insulation Self Certification scheme (CWISC) in association with the British Board of Agrément. The scheme provides homeowners with the comfort of knowing that work by registered contractors complies with the requirements of the Building regulations. Further details and a list of CIGA members who are also registered under CWISC is available on the dedicated CWISC website. In the unlikely event that you are disatisfied with the service provided by CIGA a copy of our complaints procedure is available here.
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. If the work is completed in England and Wales by an installer registered under the CWISC competent persons scheme then the Certificate also incorporates evidence of compliance with the Building Regulations.
