Health and safety pre-qualification support for contractors and suppliers who need to be accepted onto principal-contractor and client supply chains.
Based in Greater Manchester, supporting businesses across the UK.

CHAS, the Contractors Health and Safety Assessment Scheme, is a health and safety pre-qualification scheme. Clients and principal contractors use it to check that the contractors and suppliers they appoint have sound health and safety arrangements.
Applicants are assessed on how they manage health and safety: policy, organisation, risk assessment, method statements, training and competence, monitoring, and incident and accident performance.
Support is delivered by a consultant with BS 7858:2019 certification, SIA audit experience and a background in security operations, working directly with your management team.
We compare your current arrangements with what the assessment looks for and give you a prioritised list of gaps.
We tighten your health and safety policy, risk assessments and method statements so they reflect real work and stand up to assessment.
We help you assemble the evidence pack and complete the application, then support you through any follow-up questions.
We help you keep documents and records current so renewal is routine.
CHAS, SMAS Worksafe, SafeContractor and Constructionline are all members of SSIP (Safety Schemes in Procurement), whose members recognise each other’s health and safety assessments. Many clients accept more than one scheme, so check which one your target clients ask for before you apply.
