Routes to Approval

There are two routes to gaining ACS accredited status. These are equivalent to each other and ensure that the standards required of all approved contractors are consistent.

Standard Route

Open to all companies - no previous accreditation required. The Standard route to ACS approval begins with a self-assessment that is then verified by an independent assessor from an SIA-approved assessing body.

Passport Route

We accredit certain alternative quality assurance schemes as being equivalent to the ACS Standard. If your business is accredited under one of these schemes you take the Passport route to ACS approval.
