What CHAS assessors check

An assessor works through the core criteria one at a time. Knowing what they look for at each step is the difference between a clean pass and a round of queries.

The short answer

A CHAS assessor checks your submission against the SSIP core criteria, taking each one in turn and looking for clear evidence that it is met. For a contractor that is not a designer, principal designer or principal contractor, twelve criteria apply. The assessor is not looking for perfection; they are looking for a management system that is real, current and proportionate to your business, evidenced by the documents you submit.

How to make each criterion easy to tick

Assessors move fastest through submissions where each criterion has an obvious home. Label your documents so it is clear which criterion each one answers, keep everything current and dated, and make sure the evidence describes your business rather than a generic one. Where a criterion does not apply, state that with a reason instead of leaving it blank. A submission organised around the criteria the assessor is checking is far quicker to approve than a pile of documents they have to map themselves.

Common questions

What do CHAS assessors look for?

Clear evidence that each of the SSIP core criteria is met, taken one at a time. For a contractor who is not a designer, principal designer or principal contractor, twelve criteria apply, covering policy, arrangements, competent advice, training, monitoring, consultation, accidents, subcontractors, risk assessment, co-operation and welfare.

Do CHAS assessors check every criterion?

Yes. An assessor works through the applicable core criteria individually and looks for evidence on each, so a gap on any single one can hold up the application even if the rest is strong.

How do I make a CHAS assessment easier to pass?

Label your documents by the criterion each answers, keep everything current and dated, make sure the evidence describes your business, and state clearly where a criterion does not apply. An organised, criterion-mapped submission is quicker to approve.

Does the assessor verify my accident history?

Yes. The accident and enforcement criterion is checked against the HSE public register of convictions and enforcement notices, so answer it truthfully and completely.
