Is your venue or event in scope?

Four questions. Your answers stay in your browser.

1What are you checking?
2What is it mainly used for?

Schedule 1 of the Act lists the uses that count. Pick the main one if there is more than one.

3Peak number of people at once
people, including staff

Use the most people you could reasonably expect at the same time. Your fire risk assessment's safe occupancy figure, or past ticket and door counts, are good starting points.

4Is there a building on site?

Venues need a building. Events can be on open land, such as a field or park.

The duties

What Martyn's Law asks of you

The Act is named after Martyn Hett, one of 22 people killed in the Manchester Arena attack in 2017. Its duties are in proportion to the size of the venue or event, and the Security Industry Authority (SIA) will regulate it.

200 to 799 people

Standard tier

Notify the SIA. Have procedures staff would follow in an attack: evacuation, invacuation, lockdown and communication. Costs are mainly staff time.

800+ people

Enhanced tier

Everything at standard tier, plus protective measures such as monitoring the site. A written document for the SIA, and a named senior individual if you are an organisation.

800+ people, ticketed

Qualifying events

Public events with entry checks, including on open land. The organiser in control of the site for the event carries the duties, not necessarily the landowner.

Also coming for event organisers

Event safety documents, done properly

Beyond Martyn's Law, we're building templates and guided generators for the paperwork every event needs, written from the plans we use on our own festival sites.

  • Event Management PlanThe core document for your licensing authority and safety advisory group
  • Risk assessmentsSite, build, show and breakdown, in a format SAGs recognise
  • Crowd management planCapacities, flow, ingress and egress, and stewarding
  • Emergency and evacuation planRoles, routes, rendezvous points and communication
  • SAG submission packEverything pulled together for your safety advisory group

30Years' combined
experience
1k–15kPeople on site
at the festivals we run

We are event producers. Between us we have spent 30 years building and running festival sites for 1,000 to 15,000 people: crowd plans, emergency procedures, safety advisory group submissions, and the teams who carry them out on the day.

The Musterpoint turns that experience into clear, affordable tools, so smaller venues and organisers can prepare properly without paying for a consultant.

  • Plain-English guidance aligned to the published statutory guidance
  • Templates written by people who have run live sites
  • Kept up to date as the SIA's guidance is finalised
