SIA speaks on its Martyn's Law consultation work

Published

The Security Industry Authority has been talking about the consultation work behind Martyn's Law. Here's what it means for venues preparing for the new duties.

What happened

Professional Security Magazine reports comments from the Security Industry Authority (SIA) about consultation work linked to Martyn's Law. The SIA is the regulator named under the Terrorism (Protection of Premises) Act 2025. As the rules are developed, the SIA is working through how the regime will operate in practice. The finer detail of any consultation is not yet confirmed here, so treat this as a sign of work in progress rather than a settled position.

Why it matters for venues

The SIA will be the body that venues deal with once the duties begin. Its consultation and preparation work shapes things like how premises will notify, what the standard and enhanced tiers will involve, and how the regulator expects to engage with operators. Watching this work helps you understand what is coming before anything is required of you.

Remember the timing

The duties under Martyn's Law are not in force yet. Commencement is expected in spring 2027, and the exact date is still to be confirmed. The SIA's notification process is not live. There is nothing you must do today to comply, because the legal obligations have not started.

What to do now

Use this period to get familiar. If you might host 200 to 799 people at once you are likely in the standard tier; 800 or more points to the enhanced tier, and the count includes staff. Work out roughly which tier fits your premises, and keep an eye on official SIA updates so you are ready when the start date is confirmed.
