Three things venues get wrong

Scope isn't decided by an ordinary week, and it isn't decided by the number on your fire risk assessment.

Counting the quiet weeks

Scope is set by your busiest recurring occasion. A beer garden in August, a fete, a carol service, a cup final or a function booking can carry a site past 200 even when a normal Tuesday is sixty people.

Forgetting the staff

The count includes everybody present at the same time — customers, guests, congregation, performers, volunteers, bar staff and contractors. Not just paying visitors.

Assuming someone else is responsible

The duty sits with whoever controls the premises for its use — often the tenant, operator, trustees or committee rather than the freeholder. An agreement can allocate tasks. It cannot hand over the duty.

How the check works

Six questions at most, and it stops as soon as it has an answer. Everything is based on the Home Office statutory guidance published on 15 April 2026.

Answer six questions

What the premises is used for, how many people at peak, and who is in control of it.

Question 1 of 6

Common questions

Do we have to do anything yet?

No. The Act received Royal Assent in April 2025 but the duties are not enforceable until commencement, expected in Spring 2027. There is no grace period after that date, so the time now is preparation time.

Does a one-off big booking put us in scope?

Not if it could not reasonably have been expected and is not expected to happen again. A planned or recurring occasion that takes you past 200 does bring you into the standard tier.

We're a charity or a volunteer committee. Is there an exemption?

No. Scope depends on how the premises is used and how many people are present, not on your legal form. Charities, trusts, clubs and volunteer committees are treated the same as businesses.

We lease our premises. Who is responsible?

Generally whoever controls the premises for the qualifying use, which is usually the operator or tenant rather than the freeholder. Where that's genuinely unclear, settle it in writing before commencement.

Will we have to buy security equipment?

Not at standard tier. The duties there are procedural — four written procedures covering evacuation, invacuation, lockdown and communication. The guidance is explicit that no equipment purchase is required.

Is this an official government service?

No, and we say so plainly. This is an independent guide. Neither the Home Office, the SIA nor NaCTSO endorses any third-party product in respect of this legislation, and you can meet the requirements of the Act without buying anything from anyone.
