About The IAA

The Insulation Assurance Authority (IAA) is the technical authority and industry body that provides a quality assurance framework under a single compliance platform. Our framework gives homeowners, key stakeholders and funders the confidence that insulation work is carried out to the highest standards and subject to a level of rigor and surveillance which helps ensure it is done ‘Right First Time’.
With our head office based in Leighton Buzzard which has been operating for 25 years, CIGA and The IAA company group employs 40 full time staff and have supported homeowners since 1995, issuing over 6.2 million guarantees (effectively protecting 1 in every 4 homes across the UK).
