Honest comparison
For a team of one, this ranking is about economics, not features - budget, self-serve signup, and how many RAMS you actually write a month. The Site Book wins at any regular cadence with its £30/mo flat rate covering the full CDM suite, but RapidRAMS beats it on pure maths if you only write one or two documents a month at about £15 per RAMS. Breakeven lands at roughly two RAMS a month: below that, pay-per-document is cheaper; above that, flat-rate pays for itself. RAMs App is a reasonable middle ground for template browsers; CDM Wizard is a free learning starting point; Word and Excel are not recommended for anyone invoicing real clients.

A team of one has different economics from a ten-person firm, and the parent best-rams-software-uk roundup doesn't quite fit. For a sole trader, the question isn't which tool has the deepest template library or the most collaboration features - it's how many RAMS you actually write a month and whether you can self-serve sign up without a demo. This page re-ranks the same tools through that lens, with an explicit breakeven figure so you can pick on maths rather than marketing.
At-a-glance fit per product - pulled from the same data that drives the snapshot table.
Pick the option that matches how your team actually works.
If you are a one-person builder writing one or two RAMS a month at most, RapidRAMS wins on pure maths. Roughly fifteen pounds per document with no subscription is cheaper than any flat-rate plan when your usage is that low. The breakeven against The Site Book's thirty pounds a month lands at about two RAMS a month - below that, pay-per-document is the honest pick.
Recommended for: Occasional jobs - one or two RAMS a month
If you are a sole trader running regular site work and writing more than two RAMS a month, The Site Book is cheaper and wider. Flat-rate pricing from thirty pounds a month covers the full CDM suite - RAMS, CPP, COSHH, inductions, worker sign-off - in one bill, with self-serve signup and a free first project. Above the two-a-month breakeven, the maths flips in favour of flat rate.
Recommended for: Regular work - more than two RAMS a month

Short, straight answers - the same questions real builders ask.
It depends on how many documents you write. For one or two RAMS a month, RapidRAMS at roughly fifteen pounds per document is cheapest because you only pay when you draft one. For regular monthly work, The Site Book at thirty pounds a month flat covers unlimited documents plus the full CDM suite - CPP, COSHH, inductions, worker sign-off - so the per-document cost collapses as soon as you pass two documents a month.
Yes, if you are carrying out work that needs a risk assessment and method statement - which under CDM 2015 is most paid construction work, including domestic jobs above the relevant thresholds. HSE inspectors do not waive the duty for sole traders. What you can skip is enterprise tooling built for H and S managers. A simple tool aimed at one-person teams is enough to produce site-specific RAMS quickly.
Yes. There is no legal requirement to hold a specific qualification to produce a risk assessment or method statement. CDM 2015 requires that the person is competent - meaning experienced enough with the work and its hazards to assess them sensibly. A sole trader who knows their trade is typically competent to write their own RAMS, especially with software that structures hazards, controls, PPE, and emergency procedures for them.
For a domestic job under CDM 2015, you still need a risk assessment and method statement for the work itself, plus a simple construction phase plan if the project crosses the threshold. A homeowner is the client but the duty-holder responsibilities sit on you as the contractor. The Site Book is built for exactly this audience and ships domestic-ready templates that cover the typical house extension, loft conversion, and kitchen-fit scenarios.
