How to Notify the SIA Under Martyn's Law

TL;DR

Martyn's Law gives standard tier venues two legal duties: have public protection procedures, and notify the Security Industry Authority (SIA). You can't do the second one yet. The notification portal is still being built and isn't expected to open before Spring 2027. Leave your email below and we'll let you know when it does.

What Is the SIA Notification Duty?

Under Section 9 of the Terrorism (Protection of Premises) Act 2025, the responsible person for a qualifying venue must notify the Security Industry Authority that they're responsible for it. You'll also need to tell the SIA if you stop being responsible, or if the details you gave become inaccurate. Notification is free of charge.

And that's the whole duty. The SIA doesn't approve or reject anything at this stage. You're telling the regulator you exist, roughly the way you'd tell HMRC you've started trading, so it knows who's responsible for which premises.

Can You Notify the SIA Yet?

No. The SIA's notification portal hasn't opened. In its 4 June 2026 update, the SIA said Martyn's Law is expected to go live in spring 2027 and ‘you won't be able to notify us until then’. The portal is still being built: the SIA has brought in a digital partner and plans to invite volunteers to test the system from early 2027. Nobody can notify yet, and anyone charging you to ‘register’ your venue now is selling something that doesn't exist.

There's also no published deadline for how quickly existing venues will need to notify once the portal opens. Those timeframes will be set by Home Office regulations (statutory instruments) that haven't been made yet. The SIA has said practical guidance on how to notify, and what details and documents to provide, will follow later in 2026, once the system is built and the regulations are ready. When it lands, we'll update this page.

What You'll Need When It Opens

The SIA hasn't published the notification form, so nobody can tell you exactly what it will ask. It has promised guidance later in 2026 on what details and documents to provide. Until then, based on the Act, expect to provide at least your venue's name and address, what it's used for, your capacity figure, and who the responsible person is. If you've built your PPP with Standard Tier, all of that is already written down in one place.

Notifying the SIA is your legal responsibility as the responsible person. We'll tell you when it becomes possible, but the notifying itself stays with you.

The Other Duty Doesn't Wait

Notification is the quick duty. The slow one is having public protection procedures in place and making sure your staff and volunteers actually know them. That's the part an SIA inspector will ask about, and you don't need the portal to start on it.

Frequently Asked Questions

Is SIA notification the same as an SIA licence?
No. SIA licences are for security operatives like door supervisors, under separate legislation. Martyn's Law notification just tells the SIA you're the responsible person for a qualifying venue. You don't need an SIA licence to run a standard tier venue.
How much does it cost to notify the SIA?
Nothing. The Act makes notification free of charge. If someone offers to register your venue with the SIA for a fee, be sceptical: there's currently nothing to register with.
What happens if I don't notify the SIA?
Once the duties are in force, failing to notify is non-compliance. The SIA has said it will take a support-first approach, with advice and guidance before formal enforcement. But persistent non-compliance can end in a compliance notice, a penalty of up to £10,000, and daily penalties of up to £500.
When will the SIA notification portal open?
The SIA hasn't given a date. The Act's duties commence Spring 2027 at the earliest and the portal is expected to open around commencement. As of June 2026 the SIA is still building the system, and it has said it will invite volunteers to test it from early 2027. Leave your email on this page and we'll let you know when it opens.
