Manchester Arena – Martyn's Law compliance guide for UK venue security

What is Martyn's Law?

Legislation requiring venues and events to take proportionate steps to protect the public from terrorism — proportionate, not perfect.

Named in memory of Martyn Hett

Martyn was one of the 22 people killed in the 2017 Manchester Arena attack. The Act carries his name in recognition of his mother Figen Murray's campaign to make public venues safer.

How should you prepare?

Choose your role. The duties differ depending on whether you set the policy or carry it out.

1

Determine your tier

Standard Duty (200–799) or Enhanced Duty (800+). Capacity, not occupancy on a typical night.

2

Read statutory guidance

Section 27 guidance (April 2026) explains scope and requirements in plain English.

3

Respond to consultation

Open until 12 June 2026 — your input shapes how the SIA will enforce the Act.

4

Develop procedures

Evacuation, invacuation, lockdown, and communication plans — written, tested, owned.

5

Train your staff

Site-specific training is required even for SIA-licensed staff. Generic doesn't count.

6

Notify the SIA

Register through the notification portal when it opens ahead of enforcement.

What this means for security workers

The legal duty falls on venue operators — not individual workers. But as a frontline professional, you will see changes in how venues operate.

1

The duty is on your employer

Venue operators are the 'responsible person' under the Act. Your role is to follow the procedures they put in place.

2

Your SIA training covers the fundamentals

Counter-terrorism awareness, recognising suspicious behaviour, and emergency response are part of your licence-linked training.

3

Expect new procedures at work

Clearer evacuation plans, bag search protocols, updated communication chains, and more regular briefings.

4

Site-specific training will be required

Even with an SIA licence, you will need additional instruction on each venue's specific procedures.
