The Site Book vs RapidRAMS — UK CDM Compliance Tools
For occasional one-off RAMS, RapidRAMS can make sense at about £15 per document. For regular small builders, The Site Book is broader and usually cheaper: Starter £0, Pro £39/month or £360/year, Business £199/month, and optional setup is £249 one-off, not a subscription. It covers RAMS, CPP, COSHH, inductions, toolbox talks, site diary and wider CDM paperwork.
The Site Book wins as soon as you need more than two documents a month or the wider CDM suite; RapidRAMS suits one-off pay-per-document needs where a monthly subscription is unjustified.

Why this matters
RapidRAMS keeps it simple: fifteen pounds each time you need a RAMS document, no subscription, no account to manage, no features you do not use. If you only need a RAMS once in a while, that simplicity has genuine appeal. The trade-off is that the cost adds up fast once you are doing regular work. At three jobs a month RapidRAMS is forty-five pounds for the RAMS alone, while The Site Book Pro is £39/month or £360/year and includes CPPs, COSHH assessments, site inductions, worker cert tracking, permits to work, and site diary. Starter is £0, Business is £199/month, and optional setup is £249 one-off for one job's Site Book paperwork, not a subscription.

Bottom line
The Site Book wins as soon as you need more than two documents a month or the wider CDM suite; RapidRAMS suits one-off pay-per-document needs where a monthly subscription is unjustified.
Why switch to The Site Book
✓Breakeven at about two documents a month - once you are writing more RAMS than that, flat-rate is cheaper than pay-per-doc for the RAMS alone.
✓One subscription covers CPPs, COSHH assessments, site inductions, permits to work, and worker cert tracking - not just the RAMS sheet.
✓Generate a site-specific RAMS first draft from a plain-English brief in under five minutes, ready for competent-person review.
✓Starter is £0, so you can test the full CDM suite on a real project before you commit - lower friction than paying per document to evaluate.
✓Flat Pro rate of £39/month or £360/year regardless of how much work you do - steady builders see the price gap widen with every extra job.
✓Optional setup is £249 one-off for the Site Book paperwork on one job - useful if you want help once, without adding another subscription.

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.

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.

Sweet spot
A sole trader or small contractor who needs occasional pay-as-you-go RAMS and wants no subscription lock-in.
Strengths
Pay-per-document pricing is friction-free for builders who only need a RAMS occasionally -no monthly commitment.
Structured on-demand workflow for single RAMS documents, with adaptive logic rather than a static Word template.
Weaknesses
£15 per document becomes expensive fast once you need more than two RAMS a month -flat-rate tools pay for themselves quickly.
No CPP, COSHH, site inductions, or any site management tools -RAMS-only scope.
Narrow public scope: the homepage supports RAMS/method statement generation, but gives no evidence of CPP, COSHH, site inductions or broader site-management tools.
Short, straight answers - the same questions real builders ask.
When does RapidRAMS pay-per-document pricing stop making sense?
RapidRAMS charges around fifteen pounds per document with no subscription, which suits very occasional use. As soon as you write more than two RAMS in a month, The Site Book Pro at £39/month or £360/year covers unlimited documents plus the wider CDM suite. Starter is £0 and Business is £199/month, so regular builders have clearer upgrade points.
Why is The Site Book cheaper for regular users?
The Site Book was built with AI at its core: a plain-English brief produces a site-specific RAMS first draft in under five minutes, ready for competent-person review, rather than manual template filling for every job. The flat-rate plan then covers an unlimited number of RAMS, CPPs, COSHH assessments and site inductions in one subscription, so the per-document cost falls the more work you run through it.
Does RapidRAMS cover CPP and site management?
No. RapidRAMS focuses narrowly on pay-per-document RAMS for one-off needs. It does not cover Construction Phase Plans, COSHH assessments, site inductions, worker certificate tracking, or permits to work. The Site Book bundles all of these in a single flat-rate subscription, so the same tool handles every part of a CDM 2015 duty rather than just the RAMS sheet.
Can I try The Site Book without paying per document?
Yes. The Site Book Starter is £0 and lets you create your first project and generate real documents - your CPP, RAMS, and site induction - without entering a credit card. RapidRAMS only commits you to a single document at a time. If you want a free hands-on test of the full CDM suite before paying, The Site Book is the lower-friction option.
Is The Site Book setup service a monthly subscription?
No. The optional setup service is £249 one-off, covers the Site Book paperwork for one job, and is not a subscription. It sits separately from Starter, Pro, and Business plans. Builders who want the software only can start on Starter at £0, upgrade to Pro at £39/month or £360/year, or choose Business at £199/month.
Can I switch from RapidRAMS to The Site Book?
Yes. The Site Book accepts PCPP uploads and reuses the structure, so any documents you have already paid for in RapidRAMS give you a head start on your first project. Day-to-day authoring then moves into a natural-language brief that generates a site-specific RAMS first draft in under five minutes, ready for competent-person review.
