The Site Book vs RAMS AI — UK CDM Compliance Compared
RAMS AI generates RAMS, CPPs, COSHH and inductions on pay-as-you-go credits from GBP29.97 per 300, with a Professional plan at GBP39.97/mo - a good fit for contractors who issue documents irregularly. The Site Book, at GBP39/mo or GBP360/yr flat, pairs the generated CDM pack with site operations: per-worker sign-off, attendance, certificate tracking and a one-click audit pack. Choose credits for occasional paperwork; choose The Site Book to run live sites week to week.
RAMS AI's pay-as-you-go credits suit contractors who issue documents irregularly; The Site Book wins when a builder needs the full CDM pack plus site operations, worker sign-off, and an audit pack on flat pricing.

Sole trader to mid-sized
Best for
UK builders and principal contractors - from sole traders to builder-run firms of around 50 staff - who need CDM documents plus lightweight site H&S operations: RAMS, CPP, COSHH, inductions, toolbox talks, site attendance, site files, document review evidence, subcontractor evidence and worker/visitor portal access.

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confirmation before a document is shared with a client or downloaded in the app on every plan, re-sign on revision with superseded signatures preserved plus PCPP import, cert tracking and document checking from the £39/month Pro plan - and on Business, optional named-approver routing (a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.

Sweet spot
A contractor issuing RAMS irregularly who prefers pay-as-you-go credits over a fixed subscription, and wants a consistency check plus permit suggestions on top of the generated draft.
Strengths
Pay-as-you-go credit model (£29.97 per 300 credits standalone, £24.97 as a Professional top-up; ~£0.08–£0.10 per document activation) means no monthly commitment — unusual in a market of monthly-only subscriptions.
Broad AI document set beyond RAMS: CPP, COSHH, lifting plans (LOLER-aligned), site inductions, toolbox talks with digital attendance, and RIDDOR-aligned incident reporting.
AI consistency checker plus smart permit suggestions (hot works, confined space) add a review layer on top of the generated draft.
First three sample document activations are free, and building/previewing is always free — credits are only spent on activation, lowering trial friction.
Weaknesses
Very new vendor — United Applications Ltd was only registered in 2025 (Companies House 16955835), so there is little independent review evidence or track record yet.
No worker certificate / CSCS tracking, site inspections, or RFI workflow — it is a document generator, not a site-operations or workforce-management platform.
Permits are AI suggestions rather than a full permit-to-work issue-and-approve workflow.
Short, straight answers - the same questions real builders ask.
Is RAMS AI cheaper than The Site Book?
It depends on how often you issue documents. RAMS AI uses pay-as-you-go credits from GBP29.97 per 300, with a Professional plan at GBP39.97 per month. If you write documents only occasionally, credits can cost less. The Site Book charges flat pricing from GBP39 per month or GBP360 per year, but bundles the whole CDM pack and site operations into that fee.
Who should choose RAMS AI?
Choose RAMS AI if you produce Risk Assessments and Method Statements irregularly and prefer buying credits over a monthly commitment. Its pay-as-you-go model, broad AI document set covering CPP, COSHH, inductions and toolbox talks, plus a consistency checker and permit suggestions, genuinely suit occasional users. The Site Book fits better when the same project also needs worker sign-off, attendance and an audit pack.
Does RAMS AI include site inductions and worker sign-off?
RAMS AI generates site induction documents covering nine mandatory sections, which is useful. It does not, however, publicly offer worker certificate tracking, site attendance, or a live people-on-site view. The Site Book lets workers sign inductions and RAMS from their phone, tracks certificates and right-to-work evidence, records attendance, and merges everything into one audit-ready pack for inspectors.
Can RAMS AI replace The Site Book for CDM projects?
Only if generating documents is all you need. RAMS AI is a strong document generator, producing RAMS, CPPs, COSHH and inductions with a consistency checker. For most CDM projects a principal contractor also needs worker sign-off records, certificate tracking, site attendance, subcontractor evidence and an audit pack. The Site Book is built as that wider compliance workspace, not just a document generator.
How do the pricing models actually differ?
RAMS AI foregrounds pay-as-you-go: credits from GBP29.97 per 300 (GBP24.97 as a Professional top-up), roughly a few pence per document activation, with the first three sample activations free and building always free. The Site Book uses flat subscriptions from GBP39 per month or GBP360 per year, up to Business at GBP199 per month. Credits reward low volume; a flat fee rewards steady, everyday compliance work across a project.
