SafetyCulture is a powerful inspection and audit tool if you have a dedicated EHS team, a safety manager, and time to configure custom templates for UK construction. It is still a checklist and operations platform rather than a CDM document builder: creating a CDM-compliant RAMS requires setup and expertise. The Site Book gives small UK builders RAMS, CPPs, COSHH assessments, site inductions, site attendance, site files, document reviews, subcontractor evidence and inspections/actions in one focused workflow.

Short, straight answers - the same questions real builders ask.
No. SafetyCulture, formerly iAuditor, is a global inspection and audit platform - it excels at checklist-driven fieldwork and incident logging, but it is not a UK CDM document creator. It does not generate RAMS, CPPs, COSHH assessments, or method statements. The Site Book generates all of these from a plain-English job description against CDM 2015 requirements, with no template editing or per-seat upsell required.
SafetyCulture publishes a free plan plus Premium at $24 per seat per month billed annually, or $29 monthly, with Enterprise on custom pricing. The Site Book is Starter £0, Pro £39/month or £360/year, and Business £199/month with 5 internal logins plus 25 active site portal users. The comparison is not seats alone: SafetyCulture is inspection-first, while The Site Book is CDM-document and site-H&S-portal focused.
Some enterprise teams do - SafetyCulture for inspection checklists, The Site Book for CDM compliance documents. They solve different problems. SafetyCulture is about ongoing audit and inspection workflows. The Site Book is about producing the RAMS, CPP, and COSHH documents you hand to workers before they start, plus the digital site induction and worker sign-off needed to keep the audit trail intact.
The Site Book is built specifically for sole traders and small to mid UK builders working under CDM 2015. Its features map directly to UK duties - the CPP, the RAMS, the F10, the site induction. SafetyCulture is industry-agnostic and global, so its templates are not aligned with UK construction law out of the box. For a UK builder, the localisation alone saves time on every project.
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. SafetyCulture's trial is built around inspection workflows, not document creation. The Site Book lets you see the actual CDM document output on day one, which is what UK builders are evaluating.
