Accreditation scheme comparison
Assured Contractors and Constructionline compared
Constructionline, part of Once For All, is a prequalification register: suppliers pay by turnover band to be assessed to standards including PAS 91 and the Common Assessment Standard, and buyers use it to find suppliers and, with Risk Radar, to watch supply-chain risk.
Assured Contractors is software a client uses to run the contractors it has appointed, from prequalification to the site gate; contractors connect free.
Many clients use both: Constructionline to find and pre-assess suppliers, Assured Contractors to manage the ones working on their sites.

Using both
Can you use Constructionline and Assured Contractors together?
Constructionline answers “who could we use, and are they financially sound?”. Assured Contractors answers “is this contractor, and each of their people, ready for our site today?”.
A common pattern: shortlist and pre-assess through Constructionline, then send the appointed contractor your Assured Contractors company code; it joins free and is connected to you straight away. Their certificate goes on their profile, and the site team works from the same record for permits, bookings and the gate.
What Assured Contractors doesn't do
- No SSIP, PAS 91 or CAS certificateAssured Contractors isn't an assessment scheme and doesn't certify companies. Clients who require SSIP keep requiring it; contractors store the certificate on their profile with its expiry date.
- No turnstiles, biometrics or gate hardwareGate check-in is software on a phone, tablet or laptop: gate staff search the worker, see their readiness and record allow, refuse or refer with reasons.
- No live CSCS Smart Check connection yetCards are recorded with their number, expiry date and photos, and approved by the client's reviewers. Reviewers who want a live check use the CSCS Smart Check app.
