The Site Book vs CDM Wizard — UK CDM Compliance Tools
CDM Wizard is CITB's free questionnaire tool: it generates a basic CDM 2015 Construction Phase Plan for small or domestic jobs, and nothing beyond it - no RAMS, no COSHH, no method statements, no sign-off tracking. The Site Book generates the full CDM document set from a plain-English brief at £39/mo or £360/yr. Use CDM Wizard when a basic free CPP is genuinely all the job needs; use The Site Book for the whole pack.

Why this matters
Credit where it is due. CDM Wizard is a CITB-backed tool that has done genuinely good work for smaller builders - it is free, it is straightforward, and its questionnaire produces a real, basic Construction Phase Plan for small and domestic jobs. If a simple CPP is all a job needs, it remains a great starting point. The question is what comes next. Most projects also need RAMS, COSHH assessments, site inductions and signed evidence that workers actually read them - none of which CDM Wizard attempts, and editing a generated plan is limited. That is where The Site Book picks up - building on the foundation CDM Wizard laid, not replacing it.

✓Professional, site-specific CPPs from a plain-English job description - editable in the browser, where CDM Wizard's generated plan allows only limited editing.
✓RAMS, site inductions, COSHH records, emergency plans, and F10 notification checks - not just the CPP that CDM Wizard covers.
✓Digital site inductions with phone sign-off and a live compliance dashboard - features CDM Wizard does not attempt.
✓An Audit-Ready Pack that compiles every document, sign-off, and record into one report for an HSE inspector.
✓A free tier to test on a real project before committing - the natural next step once you have outgrown the free CPP questionnaire.

Sweet spot
A builder-run principal contractor on a domestic or commercial project who needs ready-to-sign CDM documents, worker sign-off, a live people-on-site view, practical site files, subcontractor evidence records and lightweight inspections/actions - without a dedicated H&S department to run them.
Strengths
UK construction compliance tool that ships RAMS + CPP + COSHH + inductions (readable and acknowledgeable in 9 worker languages on Business, with the language audit-recorded) + worker sign-off, including optional 4-digit shared-link PIN evidence on Business, plus site attendance, portal users, site files, document reviews, subcontractor evidence and inspections/actions.
Generate a site-specific RAMS first draft from a natural-language brief in under five minutes, ready for competent-person review - not a template library you hand-fill.
Controlled document workflow without an enterprise contract: version history and a recorded issue confirmation before a document is shared with a client or downloaded in the app on every plan, re-sign on revision with superseded signatures preserved plus PCPP import, cert tracking and document checking from the £39/month Pro plan - and on Business, optional named-approver routing (a designated approver accepts or rejects each version, with recorded reasons, before it can be issued) plus client approve/reject/request-changes via share links.
Transparent pricing: Starter £0, Pro £39/month or £360/year, Business £199/month with 10 management logins and 50 active site portal users. Worker document signing has no per-signature charge; project workers count as active portal users while assigned.
Build RAMS for any trade - add your own work types and method statements alongside the built-in library, reusable across projects, including a ready-made Commercial Solar PV group. Save a finished job as a reusable project template, or clone it, so the next job of the same shape starts from your own setup.
COSHH goes deep: a standalone COSHH assessment document, upload-a-Safety-Data-Sheet extraction, a site-specific substance register and an expert-reviewed library - plus per-worker RAMS sign-off and a one-click Audit Pack covering documents, sign-offs, worker evidence, attendance, incidents, COSHH, permits and up to the latest 500 live Site Diary entries.
Weaknesses
New product (launched 2026) -smaller customer base and shorter track record than established tools like HandsHQ.
Procore integration is in final testing rather than publicly launched -until it ships, compliance docs export as PDFs rather than syncing into Procore. A public REST API and signed webhooks are live on the Site Control tier; Autodesk Construction Cloud is not integrated.
Site files are a practical portal for drawings, plans and procedures, not formal drawing revision control.
UK-focused content (CDM 2015, HSE guidance) -international contractors on non-UK projects would need to adapt the output.

Short, straight answers - the same questions real builders ask.
Does CDM Wizard create RAMS and CPPs?
It creates CPPs, not RAMS. CDM Wizard walks you through a tick-box questionnaire and generates a basic CDM 2015 Construction Phase Plan for small or domestic works, emailed as a branded PDF. It does not produce RAMS, COSHH assessments, or method statements, and editing a generated plan is limited. The Site Book generates the whole set - RAMS, CPP, COSHH, and site inductions - from a plain-English job description in one platform.
Is CDM Wizard really free?
Yes, CDM Wizard is free - it is an official CITB tool, and the Construction Phase Plan it generates costs nothing. For a small or domestic job that only needs a basic CPP, that is genuinely useful. But the CPP is where it stops: no RAMS, no COSHH, no inductions and no worker sign-off. The Site Book covers that full set, with Pro at GBP39/month or GBP360/year after your free first project.
Can I use both tools together?
You could - CDM Wizard for a quick free CPP on a simple domestic job, The Site Book for everything else. In practice most builders outgrow the split fast: the moment a job needs RAMS, COSHH, inductions or worker sign-off alongside the CPP, you are juggling two systems. The Site Book generates the CPP and the rest of the pack in one place, so the whole compliance record lives together.
When is CDM Wizard enough on its own?
For a small or domestic project where a basic Construction Phase Plan is the only document you need, CDM Wizard's free questionnaire can be enough. It is not designed for the wider job: it does not generate RAMS, COSHH assessments or method statements, does not track worker sign-off, and editing a generated plan is limited. Once a project needs those, The Site Book is the right tool.
Can I try The Site Book before committing?
Yes. The Site Book has a free tier that lets you create your first project and generate real documents - your CPP, RAMS, and site induction - without entering a credit card. You see exactly what the platform produces before deciding whether to upgrade. That is a practical next step for anyone who has outgrown CDM Wizard's single free CPP.
