BIOR members and certified members. Every one opens its own verification page.

Certified means the business or recruiter has committed to the BIOR Code of Professional and Ethical Conduct and has passed the BIOR certification assessment; the date shown is the date they were last certified, and certification lasts five years from it. Member means a current membership whose certification assessment is still to be taken or renewed. Both can be checked on the verification page the name opens.

Choosing a certified or member business is the simplest check you can make before you sign terms. From 30 October 2026 you share responsibility for the treatment of agency workers on your sites, so who you work with matters more than it did.

A listed business or recruiter has agreed to a published code that covers how you are treated, what you are told and how you are paid. If something goes wrong, there is a complaints procedure you can use.

BIOR membership includes the certification assessment. Agency Membership is explained at ior.org/agency-membership, Personal Membership at ior.org/personal-certification and STAR for in-house recruiters at ior.org/star. Individual members choose from their dashboard whether to be listed by name; every member can be checked by number at ior.org/verify.

Search this page by name, town, sector or specialism, or enter a membership number or a name at ior.org/verify. The verification page shows whether the BIOR membership is Active or Lapsed, the credential and the dates, and certified entries show the certified mark. Membership of a professional body is voluntary; the Employment Agencies Act 1973 and the Conduct Regulations 2003 apply to every UK agency regardless, and the Fair Work Agency enforces them.
