What is a 25 year CIGA guarantee?

All of our installations of Cavity Wall Insulation come with a 25 year CIGA guarantee to ensure that your works hold up and are at the very least to the industry standard expectation so that you can have peace of mind that you won’t experience rot, damp or cold spots.

Who are CIGA?

CIGA or the Cavity Insulation Guarantee Agency are an independent body who provide guarantees that last 25 years when installation is fitted by an approved contractor within the UK/Channel Islands,

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 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.

All members installers of CIGA are assessed for competence and must follow the technical guidance for the material used and CIGA Best Practice Guidance. A summary of the requirements that members must meet and their obligations can be reviewed here.

What does this guarantee cover?

The CIGA Guarantee covers defects in materials or workmanship and any concerns will be investigated and and defects rectified free of charge.

  • Any claim under the Guarantee must be notified to CIGA within 25 years of the installation date.
  • All problems relating to the installation must be reported to the installer as soon as practicable and CIGA must be informed if the matter is not resolved satisfactorily within 2 months.
  • The guarantee is not valid if the insulation has been altered or disturbed.
  • Your statutory rights are not affected by the guarantee.
  • The guarantee remains valid for subsequent owners or occupiers of the property.
  • The maximum value of rectification work is currently £20,000.

These notes are for general guidance only, and you should refer to the CIGA guarantee for precise details of the cover on your installation.

Do all companies offer a CIGA guarantee?

No – not all companies operating in the cavity wall insulation industry offer a guarantee against their work.

How do I get a CIGA guarantee?

If your cavity has been filled previously – you may already have one! The best way to check is by contacting CIGA

If your cavity is empty – speak to us after filling out our Eligibility Checker. We’ll come and survey the property (free of charge) and subject to funding complete the work free of charge also. Once the work is finished and final payment has been received we 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.
