The framework

The Compliance.One Standard

Our Compliance Certification is built on the Compliance.One Standard — a comprehensive framework aligned to UK best practice and the full spectrum of labour-supply legislation.

It provides independent assurance that your organisation engages, manages and governs contingent labour ethically, transparently and in accordance with statutory requirements.
