MARTYN'S LAW COMMENCES SPRING 2027 ·

Bloop

FREE CHECKER · NOTHING STORED

Which Martyn's Law tier applies to you?

Answer six questions and this runs the tests in the Terrorism (Protection of Premises) Act 2025 against your answers, then shows you which provision decided the result. It is the same rule engine that runs inside Bloop, so the answer here is the answer the product gives. No account, no email, no record kept.

Where there are several uses, choose the principal one (s.4(2)). Four of these uses stay at standard tier however many people are present.

Which method you used is itself a notifiable fact, which is why this asks rather than just taking a number.

Employees, contractors, volunteers and anyone else working.

THE TWO THRESHOLDS

Where the lines actually fall

STANDARD TIER · 200 TO 799

Premises used wholly or mainly for a Schedule 1 use where 200 or more people may reasonably be expected to be present at the same time (s.2(2)(c)). The duties are procedures for evacuation, invacuation, lockdown and communication, and notification to the regulator.

ENHANCED TIER · 800 AND ABOVE

The same, at 800 or more (s.2(3)(c)). It adds public protection measures, a compliance document, and a designated senior individual where the responsible person is not an individual.

A qualifying event is a separate test again (s.3(1)): premises the public can access to attend, 800 or more people expected, and entry conditional on payment, a ticket, a pass or membership, checked at the door. Six conditions, all of which have to be met. An event in a public park still qualifies even though the park itself is excluded from the premises definition, which is the case most often got wrong.

COUNTING PEOPLE

The number is peak simultaneous, and it includes staff

Not the total through the door across a day. It is the most people present at any one moment, and everyone working counts. There are six recognised ways of arriving at it, from the non-statutory Supplementary Document A. Two of them, historic attendance data and ticket allocation, count the public only, so staff have to be added separately.

  • Method A: fire safety occupancy figure
  • Method B: historic attendance data (counts the public only, add staff separately)
  • Method C: fixed capacity, such as seating
  • Method D: tickets and pre-registration (counts the public only, add staff separately)
  • Method E: licence or other capacity restriction
  • Method F: another method you can justify

The duties are not yet in force. Commencement is expected no earlier than spring 2027 and the date is not confirmed. For what each tier has to do, read the tier guide, or Martyn's Law translated for live events.

General guidance, not legal advice. Bloop is a system of record: it holds the evidence of what you did and when. The duty holder remains legally accountable and nothing here is sent to the Security Industry Authority or anyone else. Read the Act itself on legislation.gov.uk.
