About Us
Independent Certification, Built on Confidence
International Assessment Bureau (IAB) is an independent certification body based in the UK, carrying out audits and issuing certification against internationally recognised management system standards, helping organisations of every size demonstrate quality, safety, environmental and governance performance to their customers, regulators and partners.
About IAB
International Assessment Bureau is an independent certification body based in the UK. We offer a range of certification schemes designed to give organisations a clear, practical pathway to meet market requirements, whether those requirements are driven by regulation, by customers, or by an organisation's own ambitions for continual improvement.
IAB was established to give organisations of every size and sector access to thorough, evidence-based audits carried out by experienced assessors, delivered in a way that is efficient, transparent and genuinely useful to the business being certified — not just a paperwork exercise. Since then we have grown our scope to cover a wide range of ISO and sector-specific standards, while keeping the same focus on independent, impartial assessment at the centre of everything we do.
International Assessment Bureau Ltd is a company registered in England and Wales (company no. 16009936). That gives every client a UK-based point of contact, UK company-law accountability, and a certification process that is straightforward to deal with from first enquiry through to ongoing surveillance audits.
