Approved Contractors

All contractors must, as a condition of working for us, provide up-to-date copies of insurances, health & safety compliance and other relevant documentation, and must keep these updated. This provides the all-round assurance that we are working together in meeting necessary legal and professional standards.

What is the ACCL?

Our Contractor and Consultant List (ACCL) is a detailed internal list of suppliers that have undergone due diligence screening as part of the acceptance process.  After sign-up, contractors are required to keep key certification up-to-date as a condition of membership.

How do I join?

Membership is strictly by invitation. We cannot consider unsolicited requests to join, and listing does not in itself guarantee any work.

Following an invitation, you will first need to register your company on In-Tend

You will then need to complete a set of questionnaires and to submit supporting insurance certificates and other documents as electronic (‘soft’) copies. You can see an indicative list under Due Diligence. This demonstrates that your company operates to full legal and professional standards.

As each certificate expires, you will be reminded to upload a new copy to remain on the ACCL.

Leaving the ACCL

If at any time you wish to have your company removed from the ACCL, please contact the Procurement team via

We may at our discretion suspend or remove a contractor due to failure to keep certificates up-to-date, financial status, quality of work, long-term inactivity or other reasons.
