Honest comparison
The Site Book Site Control is the best contractor induction choice for principal contractors running live UK sites: contractors self-join through a permanent entrance QR, complete the site induction on their phone with CSCS credential capture, and induction gating blocks check-in until it is done, per site with unlimited workers. GoContractor fits large multilingual pre-arrival onboarding, Intasite fits induction plus visitor management across infrastructure sites, and Altora fits reusable online inductions with competency tracking.

Contractor induction is where site inductions stop being a briefing and start being a control: the people arriving are not yours, their credentials are unverified, and the record of what they acknowledged is the evidence that protects you. The tools here split by when they do the work — GoContractor before arrival, Intasite at pre-registration, Site Control at the gate itself with a self-join QR and check-in gating — and by whether the induction lives inside a wider compliance pack or feeds someone else's access system.
At-a-glance fit per product - pulled from the same data that drives the snapshot table.
Pick the option that matches how your team actually works.
Choose The Site Book Site Control when contractors arrive at the gate and need inducting before they set foot on site: a permanent entrance QR lets them self-join, the induction and CSCS credential capture happen on their own phone, and gating blocks check-in until both are done — with attendance, RFIs, document-review evidence and the generated UK CDM pack in the same per-site tool with unlimited workers.
Recommended for: Principal contractors inducting subcontractors on live sites
Choose GoContractor when the priority is pre-arrival: workers complete orientation and credential checks in their own language before day one, so the gate queue disappears. It is software-only with per-worker QR codes and credential-expiry alerts, and feeds an existing access-control or badging system rather than replacing it.
Recommended for: Large contractors onboarding multilingual subcontractor pools before arrival
Choose Intasite where induction and visitor logging are the same problem — construction and infrastructure operators running several locations, with pre-registration so contractors and visitors complete inductions before arrival and multi-site reporting across the estate.
Recommended for: Infrastructure operators combining inductions with visitor management

Short, straight answers - the same questions real builders ask.
Site induction apps are built around the induction content a builder gives their own workers. Contractor induction software is built around external people: subcontractors and visiting trades who must be onboarded, credential-checked and recorded before working on a site they do not belong to. The practical differences are self-service joining, credential capture, and gating, meaning whether the tool can stop an un-inducted contractor from checking in at all.
Yes in practice. CDM 2015 requires the principal contractor to ensure every worker on a construction site receives a suitable site induction covering the site's rules, hazards and emergency arrangements, and that applies to subcontractors and visiting trades as much as direct employees. Digital tools matter because they produce the evidence: who was inducted, when, and what they acknowledged, which is exactly what an HSE inspector asks for.
With pre-arrival platforms, yes: GoContractor is built around completing orientation and credential checks before day one, in the worker's own language, and Intasite offers pre-registration for contractors and visitors. The Site Book Site Control complements this at the gate: a permanent entrance QR lets an unannounced contractor self-join, complete the induction on their phone and upload their CSCS card in minutes, with check-in blocked until it is done.
No. Every tool in this comparison is software-first: The Site Book Site Control uses a permanent entrance QR plus browser sign-in on the worker's phone, GoContractor issues per-worker QR codes that feed existing badging systems, and Intasite and Altora run inductions online. Hardware only enters the picture if you need physical access control, turnstiles that physically stop entry, which is a separate purchase these tools integrate with rather than provide.
The site-specific essentials: site rules, the significant hazards on the site right now, emergency and first-aid arrangements, welfare locations, traffic routes, and who to report to. It should also capture the contractor's credentials, such as their CSCS card, plus an acknowledgement record. Keep it proportionate: fifteen focused minutes reflecting the actual site beats a ninety-minute generic video, and the evidence trail matters as much as the content.
