Martyn's Law for small theatres and cinemas

Updated June 2026 · Based on the Terrorism (Protection of Premises) Act 2025 and the Home Office statutory guidance published April 2026 · Not legal advice

In short

Theatres and cinemas have the easiest Martyn's Law count in the sector: your seats, plus everyone working the show — cast, crew, front of house, bar. At 200+ across the premises at the same time you're likely standard tier from Spring 2027. The encouraging part: licensed venues already run most of the required thinking; invacuation and lockdown are the genuinely new questions.

Last reviewed: June 2026 · Sources: Home Office Section 27 statutory guidance (April 2026); SIA draft section 12 guidance (April 2026).

Most venue types have to puzzle over the 200-person threshold. You mostly have to read your own seating plan.

The count: seats, then everyone behind and in front of the curtain

The test is whether 200 or more people may reasonably be expected to be present at the same time — across the whole premises. For a single-auditorium theatre that's: the house at realistic capacity, plus cast and musicians, crew and techs, front of house, box office and bar. A 170-seat theatre with an am-dram cast of twenty, six crew and ten volunteers front of house is a 200-person building on a sold-out night — the seat count alone would have told you the wrong answer.

For multi-space venues — a two-screen cinema, a theatre with a studio space — the count is across the premises at the same time: two 120-seat screens with staggered start times can comfortably exceed 200 people in the building at once. Count the building, not the room. Three minutes in our scope checker settles it.

If your honest sold-out-plus-everyone number stays under 200, you're likely out of scope — record the reasoning (capacity, typical company size, the date you considered it) and review it annually or when anything changes.

Why you start 80% prepared

In scope means standard tier (the enhanced tier starts at 800+), and standard tier asks three things: notify the SIA when its system opens, have four workable procedures, and make sure your people know them. Here's the encouraging part — as a licensed venue you already live most of this:

The genuinely new thinking: invacuation and lockdown

Two procedures won't map onto anything in your fire folder, and they're worth the real thought:

Visiting companies and hirers slot into the same picture the way they already do for fire: a paragraph in the hire agreement and a copy of your procedures in the get-in pack covers the coordination expected of you.

Common questions

Our theatre has 190 seats — are we under the Martyn's Law threshold?

Maybe not. The count is everyone reasonably expected on the premises at the same time — audience plus cast, crew, front of house and bar. A 190-seat house routinely becomes a 220-person building on a sold-out night. Count the building, not the auditorium.

How does the threshold work for a multi-screen cinema?

Across the premises at the same time. Two or three modest screens with overlapping showings, plus foyer and staff, can total 200+ in the building at once even though no single screen comes close. Stagger times don't reset the count — simultaneity does.

We're volunteer-run amateur theatre — do the same rules apply?

Yes — the law looks at the premises and the numbers, not at whether anyone's paid. The duties are deliberately proportionate, and volunteer-run venues' habit of briefing front of house per show is most of the compliance already; the addition is covering the four procedures and keeping a record of who's been briefed.
