Common Assessment Standard vs SSIP: What's the Difference?

The Common Assessment Standard (CAS) and SSIP (Safety Schemes in Procurement) are often confused, but they cover very different ground. SSIP deals only with health and safety competence and provides mutual recognition between H&S assessment schemes. CAS is far broader - a full pre-qualification framework covering 10 areas, of which health and safety is just one. CHAS and Constructionline are not standards at all; they are assessment bodies that can certify you against both SSIP and CAS. This guide explains how they relate, where they overlap, and which your business actually needs.

PPN 03/24 Explained: What It Means for Construction Pre-Qualification

Procurement Policy Note PPN 03/24 is UK Government guidance, issued in March 2024, that directs public sector contracting authorities to use the Common Assessment Standard (CAS) when pre-qualifying suppliers for construction works. For public sector projects above the £5.337 million threshold, CAS is now the preferred pre-qualification method, replacing PAS 91. PPN 03/24 is guidance to buyers rather than a law imposed on contractors - but in practice it means CAS compliance is increasingly a gate to public sector construction work. This guide explains what PPN 03/24 says, who it affects and what suppliers and buyers should do about it.

What Is the Common Assessment Standard (CAS)? A Complete Guide

The Common Assessment Standard (CAS) is the UK construction industry's standardised pre-qualification questionnaire (PQQ), developed by Build UK. It replaced PAS 91 - which was withdrawn by BSI in April 2023 and is now the preferred pre-qualification method for public sector construction procurement under Procurement Policy Note PPN 03/24. CAS uses a single industry-agreed question set, divided into 10 sections, that lets a supplier prove their capability and compliance once and share it with multiple buyers. The current Version 5 (published 1 July 2025) made the Building Safety section mandatory. Around 21,000 suppliers now hold CAS certification through one of seven Recognised Assessment Bodies.

How to Score Supplier Risk

Not all suppliers carry the same level of risk. Some suppliers may be financially stable, highly compliant and operationally reliable, while others may introduce significant risks that could impact project delivery, compliance, safety or reputation.

A structured supplier risk scoring process helps organisations make more informed decisions by identifying, measuring and prioritising supplier risk in a consistent and measurable way. This article explains how to score supplier risk step by step and includes a practical supplier risk matrix approach that can be used across construction and supply chain operations.
