Honest comparison
No single induction tool wins for everyone: One.site is the cheapest published price, SignOnSite leads on geofenced sign-in and evacuation, and only The Site Book's Site Control generates the UK CDM pack the induction references while gating entry per site.
UK digital site induction software splits into induction-first point tools (One.site, Intasite, Altora, Keyzo), construction-native sign-in suites (Collabor8Online, SignOnSite) and broad safety platforms (HammerTech). All deliver online inductions and most check CSCS cards; none generate the UK CDM pack. The Site Book's Site Control gates induction and generates the RAMS, CPP and COSHH it references, then runs attendance and RFIs per site on a transparent price.

Pick the option that matches how your team actually works.
Site Control is the only option here that gates induction and generates the RAMS, CPP and COSHH the induction references, then runs attendance, RFIs and a per-contractor audit trail.
Recommended for: Principal contractor who must generate the UK CDM pack as well as induct
One.site publishes per-site annual pricing around £1,000–£1,200 with CSCS verification and QR/kiosk sign-in, making it the most transparent low-cost induction-first pick.
Recommended for: UK housebuilder wanting the cheapest published per-site induction price
SignOnSite's induction-on-sign-in, automatic attendance and evacuation muster genuinely lead for live-site presence and roll-call, which a document-first tool does not match.
Recommended for: Contractor wanting induction delivered at a geofenced sign-in plus evacuation
HammerTech's breadth across inductions, permits, inspections and onboarding suits larger multi-site general contractors that want one wide safety platform.
Recommended for: Mid-to-large general contractor wanting a broad safety suite
Collabor8Online bundles induction-gated sign-in, RAMS approval and subcontractor management in one UK-hosted suite, a fit for contractors avoiding several point tools.
Recommended for: UK contractor wanting inductions inside a broader UK-hosted suite

Short, straight answers - the same questions real builders ask.
It depends on your need. One.site offers the cheapest published per-site price with CSCS verification, SignOnSite leads on geofenced sign-in and evacuation, and HammerTech is broadest. For a principal contractor who must generate UK CDM documents such as RAMS, CPP and COSHH as well as induct workers, The Site Book's Site Control is the only option here that gates the induction and generates the paperwork the induction references, in one tool.
Almost none of it does. Tools such as One.site, Intasite, Altora and Keyzo deliver inductions and capture sign-off but expect you to author RAMS, CPP and COSHH elsewhere and reference them in the induction. Only The Site Book's Site Control generates the full UK CDM pack from the project brief and gates entry on it, so the documents and the induction that references them live in the same platform instead of two.
Most vendors are quote-led, but a few publish figures. One.site lists roughly £1,000 to £1,200 per site per year, and SwipedOn-style sign-in tools publish per-location subscriptions. Collabor8Online, Intasite, Altora, Keyzo and SignOnSite are quote-only. The Site Book's Site Control is transparent at £675 per site per month plus a one-off setup, with unlimited workers per site rather than a per-worker charge.
Lightweight induction apps suit small builders who only need a worker to watch a briefing and sign, and our best-site-induction-apps roundup covers those. Digital site induction software for larger UK sites adds CSCS verification, induction-gated sign-in, attendance and reporting across multiple contractor companies. The Site Book's Site Control sits at the heavier end, gating entry and generating the CDM documents the induction references rather than stopping at sign-off.
The stronger tools can. Induction-gated sign-in means a worker cannot sign in until the induction, and often a CSCS card check, is complete. One.site, Collabor8Online and SignOnSite enforce this to varying degrees. The Site Book's Site Control makes sign-in a hard control gate: no completed induction and valid CSCS card means no QR check-in, and it records the whole audit trail per contractor company for inspection.
