THE INSTALLATION ASSURANCE AUTHORITY GROUP
Company number 03044131 · Monitor this company
Executive summary
The Installation Assurance Authority Group presents a financially unusual profile as a guarantee provider, with £8 million in negative net assets driven by £14.5 million in provisions for future guarantee claims – a structural deficit inherent to its business model rather than a sign of failure. While the company is technically insolvent on paper, its positive working capital (£1 million), recovering cash position, and reducing provisions suggest underlying stability. The declining asset base (41% reduction since 2018) and the strategic rebranding from "Cavity Insulation Guarantee Agency" indicate a business in transition that must carefully manage its guarantee fund adequacy while diversifying revenue streams.
