Why choose CHAS?

CHAS makes compliance easier to manage by combining robust in-house audits, trusted contractor data and practical support in one place. That means less time spent chasing paperwork, more confidence in contractor selection and stronger control over supply chain risk.

Our contractor audits are carried out by in-house assessment specialists and aligned to key legislation and recognised standards, including the Procurement Act 2023, CDM Regulations, the Building Safety Act, SSIP and the Common Assessment Standard. This helps you strengthen internal controls, close compliance gaps and address risk before it becomes a procurement or operational issue.
