What it covers and whether it is required
A CIGA guarantee is a defined protection for eligible work, not a general licence to install every type of insulation. The guarantee must be checked against the property and installation details.
Joining requirements and costs
Installer approval and the relevant guarantee arrangements require the business to meet the applicable scheme requirements. The official site describes competence assessment and technical guidance through IAA arrangements. Use the current route rather than assuming an old CIGA membership document is still the application process.
Check the current fees with Cavity Insulation Guarantee Agency before applying. Ask whether the quotation includes application, assessment, renewal and any per-job charges. Use published fees or ask for a written quotation.
What it means for homeowners
Check whether the property has a CIGA or IAA guarantee and obtain a copy of the document. The site describes 25-year cavity wall insulation guarantees, but cover, exclusions and claim handling depend on the issued terms. Contact the named organisation before arranging remedial work.
How to check a claim
Official member, card or certificate check: Cavity Insulation Guarantee Agency.
Match the record to the named person or contracting business. Check the current scope, not just a logo on a van or an old certificate. If the public record does not show the detail you need, ask the body to confirm it before appointing the business.
Where the scheme applies
The published guarantee information covers eligible UK and Channel Islands installations. Check the specific property’s certificate and the service currently responsible for it.
Common questions
Does every cavity wall insulation job automatically have a CIGA guarantee?
No. Check the installation’s actual certificate, installer and property details. A generic reference to cavity insulation is not proof of cover.
How do I check Cavity Insulation Guarantee Agency status?
Use the official verification service linked in this guide. Match the person or legal business name, current status and relevant work category. For a guarantee, check the document issued for your contract as well.
