Why this matters

Credit where it is due. CDM Wizard is a CITB-backed tool that has done genuinely good work helping smaller builders get to grips with CDM 2015 - it is free, it is straightforward, and for many builders it was the first time they engaged with CDM compliance at all. If you are just starting to learn the regulation, CDM Wizard remains a great starting point. The question is what comes next. Once you understand the basics, you need a tool that actually produces professional, site-specific documents and covers more than just the CPP checklist. That is where The Site Book picks up - building on the foundation CDM Wizard laid, not replacing it.

Bottom line

The Site Book wins when you need site-ready RAMS, CPP, and COSHH documents; CDM Wizard is a useful free learning tool for understanding CDM 2015 basics, but it does not produce compliance documents.

Why switch to The Site Book

  • Professional, site-specific CPPs created from a plain-English job description - not a checklist you still have to turn into a proper document yourself.
  • 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 learning checklist.

Sweet spot
A principal contractor on a £50k–£5m domestic or commercial project who needs ready-to-sign compliance docs and worker sign-off from a phone.

Strengths

  • Only UK construction compliance tool that ships RAMS + CPP + COSHH + inductions + worker sign-off in one flat-rate subscription.
  • AI-generated documents are site-specific from a natural-language brief, not a template library you hand-fill -cuts writing a RAMS from 2 hours to under 5 minutes.
  • Worker sign-off, PCPP import, cert tracking, and document checking are included at the entry tier, not locked behind an enterprise plan.
  • Transparent flat-rate pricing starting at £30/mo -no per-seat surprise as the team grows.

Weaknesses

  • New product (launched 2025) -smaller customer base and shorter track record than established tools like HandsHQ.
  • No Procore / Autodesk Construction Cloud integrations yet -compliance docs live inside The Site Book and export as PDFs rather than syncing into a wider PM stack.
  • UK-focused content (CDM 2015, HSE guidance) -international contractors on non-UK projects would need to adapt the output.

Sweet spot
A first-time principal contractor who needs to understand the CDM 2015 framework before producing site-ready documents.

Strengths

  • Free to use -a low-barrier way to learn CDM 2015 basics before picking a paid compliance tool.
  • Focused checklist format is straightforward for builders new to CDM regulations.

Weaknesses

  • Does not produce site-ready RAMS, CPP, COSHH, or method statements -it's a learning tool, not a document generator.
  • No site management features at all (inductions, permits, incident log, worker tracking).
  • Suits only the narrow learning-CDM-basics use case -builders still need a separate tool for actual compliance documents.

Frequently asked questions

Short, straight answers - the same questions real builders ask.

Does CDM Wizard create RAMS and CPPs?

No. CDM Wizard is a learning-focused tool - it walks you through CDM 2015 as a checklist but does not produce site-ready RAMS, COSHH assessments, or method statements. If you need actual compliance documents for a real project, you still need a separate tool to create them. The Site Book generates all of these from a plain-English job description in a single platform.

Is CDM Wizard really free?

Yes, CDM Wizard is free to use. That makes it a reasonable first stop for builders who are brand new to CDM 2015 and want to understand the framework. But free walkthroughs do not produce the documents you hand to workers on site - that is the job The Site Book does, with a starter plan from thirty pounds a month.

Can I use both tools together?

You could - CDM Wizard for understanding the regulation, The Site Book for producing the documents. But The Site Book's in-app AI chat and document quality checking already explain CDM requirements contextually while you work, so most users skip the separate learning tool once they start. One platform handles both knowledge and output without juggling tabs.

Which tool is right for which stage of learning CDM 2015?

CDM Wizard is best for someone learning the basics of CDM 2015 for the first time. It does not generate documents and is not designed for live project use. The Site Book is the right tool once you need to actually produce a CPP, a RAMS, or a site induction for a real job. Different stages, different tools.

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 the CDM Wizard checklist.
