What is this?
The Events Bible is a free, plain-English companion for planning a safe event in the UK. It turns the law and the recognised official guidance — the Purple Guide, the Green Guide, HSG195 and Martyn's Law — into tools you can actually use, with the right answer for England & Wales, Scotland or Northern Ireland.
No sign-up, no tracking. Your event details stay in your browser — nothing is sent to a server.
Plan your event
Describe your event once and the site builds the rest around it: tailored advice on the laws and licences you trigger, indicative staffing & toilet numbers, a starter risk assessment, a planning timeline, and a printable Event pack.
Reference & calculators
Search the legislation, hazards, standards and glossary; work out safe capacity and medical cover; explore the relationship map of who's legally responsible for what; or work through the pre-event checklist.
How it works
- Set your role at the top of the page — it adjusts how much detail every section shows.
- Describe your event under My Event (or load an example to see it in action).
- Work through the tools — advice, provision, risk assessment, timeline — then print or save your Event pack.
Everything in here
⚠️ The Events Bible is reference and planning guidance, not legal advice, and not a substitute for a full risk assessment by a competent person. Always check the current edition of any cited source before relying on it for a real event sign-off.
Describe your event once here. Everything else — the advisor, provision calculators, risk assessment, timeline and Event pack — reads from this. Saved in your browser only (no account, no server).
Indicative provision from your event profile. Adjust attendance and details under My Event. Figures are planning starting points — confirm against a full risk assessment.
A starter risk assessment built from your event profile — we pre-load the hazards your event is likely to face. Edit the controls, score each risk, add your own, then print. A starting point, not a finished assessment.
A planning countdown from your event date. Typical lead times — calibrate to your event and local Safety Advisory Group.
One combined summary of your event's safety picture, ready to print or save as PDF. Pulls together your profile, the advisor's considerations, provision and the timeline.
How to structure and set up an event safely — the same journey explained at your level. Switch persona above to see more or less detail.
How the pieces connect — events, the people involved, their legal duties and who enforces them. Drag nodes, click one to focus its links. The map grows with your persona.
Answer a few questions about your event and we'll flag what to look at — the laws, hazards, documents and provision your choices trigger. Indicative guidance, not a substitute for a full risk assessment.
Medical needs-assessment using the recognised Event Safety Guide (HSG195) calculation — score the event across Tables A–L for a suggested resource level. Guidance only; the Purple Guide frames medical needs as a needs-assessment, so treat the result as a starting point to agree with a competent event medical provider and the ambulance service.
Safe capacity = the lower of occupancy (area × density) and egress (exit width × flow rate × time). Figures from the Green Guide (SGSA). The system capacity is limited by its narrowest element — verify on site. For emergency egress the Green Guide discounts the widest exit (assume one exit is lost to the incident).
