This directory is compiled from public sources (UKAS schedules, the UK Government’s conformity assessment body register, the IECEx body list and company sites) and is not exhaustive. Accreditation scopes, approved-body numbers and ownership change often, so confirm scope on the UKAS register or the UK CAB register before booking. Facilities marked Non-UKAS are not UKAS accredited for the work listed (or have not said so); their reports can support a self-declaration but may not satisfy customers or regulators who ask for accredited results. Facilities you add are saved in this browser only.
