The SIA Confirmed as Martyn's Law Regulator: What That Means for You
Published
The Security Industry Authority will oversee Martyn's Law. GOV.UK has published a new collection explaining the SIA's role, though the duties themselves are not yet in force.
What happened
The government has published a new set of pages on GOV.UK setting out the role of the Security Industry Authority (SIA) as the regulator for Martyn's Law, the everyday name for the Terrorism (Protection of Premises) Act 2025. The material explains how the SIA will take on this responsibility once the law's duties come into effect.
Who the SIA is
The SIA is the body that already licenses the private security industry in the UK. Under Martyn's Law it gains a new role as the regulator overseeing how premises prepare. Its notification process for venues is not yet live, and the duties are expected to commence in spring 2027, with the exact date still to be confirmed.
What it means for venues
If you run a pub, church, hall, cinema or event space, the SIA is the organisation you will eventually deal with for Martyn's Law matters. Knowing who the regulator is now helps you understand where future guidance and notification steps will come from. Nothing is enforceable today, so this is about getting familiar, not rushing.
What to do now
Have a quick look at the GOV.UK collection so you recognise the SIA's role. Note whether your premises might fall into the standard tier (200 to 799 people, including staff) or enhanced tier (800 or more). Keep an eye out for the SIA's official channels as more detail is released ahead of commencement.
