The Common Assessment Standard (CAS) is a standardised prequalification framework designed for the construction industry in the UK. It was introduced by Build UK and supported by a range of trade associations, major contractors, and clients to streamline the prequalification process for subcontractors and suppliers. For more information on the Common Assessment Standard please visit our page here.

The Common Assessment Standard consolidates supplier and contractor data in one standardised format. Approved prequalification assessments can be shared with multiple clients, reducing duplication and creating a consistent data source. For more information on data sharing please visit our data sharing page here.

SSIP (Safety Scheme in Procurement) is a pre-qualification scheme in the construction industry that verifies a supplier’s health and safety credentials. Compliance Chain is an SSIP member who can perform SSIP assessments. SSIP assessments can be arranged as part of the membership sign-up process to streamline prequalification and tendering, and existing members can request an assessment if their SSIP certification is due to expire.

Compliance Chain follows the 10 compliance areas outlined within the Common Assessment Standard these are as follows:

• Financial Information
• Corporate & Professional Standing
• Health & Safety
• Environmental Management
• Quality Management
• Building Safety
• Fairness, Inclusion & respect
• Information Security
• Information Management
• Transport & Delivery

At Compliance Chain, we offer a Desktop Assessment, a streamlined, remote evaluation of submitted documentation.

This assessment allows suppliers to demonstrate compliance efficiently, making it a practical option for meeting industry standards without the need for an on-site assessment.
