What Is CHAS Accreditation? Complete Guide for UK Contractors in 2026

Health and safety compliance remains one of the most important requirements for contractors operating in the UK construction, facilities management, engineering, maintenance, and public sector industries. Clients increasingly expect contractors to demonstrate their commitment to health and safety, risk management, and legal compliance before awarding contracts. One of the most recognized schemes for demonstrating these standards is CHAS accreditation. Whether you are a sole trader, small business, subcontractor, or large contractor, achieving CHAS accreditation can significantly improve your credibility and access to new business opportunities.

In 2026, CHAS continues to be one of the leading accreditation schemes in the UK and plays a major role within the SSIP framework.

What Is CHAS Accreditation?

CHAS stands for Contractors Health and Safety Assessment Scheme. It is a UK-based accreditation program that assesses contractors and businesses against recognized health and safety standards. The scheme was established to help organizations demonstrate compliance with health and safety legislation while reducing the need for repeated pre-qualification assessments from different clients. CHAS reviews a company’s health and safety management systems, policies, procedures, risk assessments, training records, and compliance documentation. Once approved, contractors receive accreditation that can be used to demonstrate competence to prospective clients.

CHAS accreditation is widely recognized across the following: 

Construction Industry
