Notification deadlines are set: three months from the day the duty starts
· Written up 8 September 2026
The Act always said venues would have to notify the SIA but never said how quickly. Regulations made in July finally put a number on it, and for premises the number is three months.
What happened
The Terrorism (Protection of Premises) (Notification Requirements) Regulations 2026 were made on 9 July 2026 and laid before Parliament on 14 July. They set the 'required time' for notification, which the Act itself had left to regulations.
For premises, the responsible person on the day the duty starts gets three months from that day to notify. Become responsible later and it's the later of three months from commencement or 28 days from taking over. Stop being responsible, or find that something you already told the SIA is now wrong, and the window is 28 days. Qualifying events run on a shorter 14-day clock tied to when the event is first publicised.
The Home Office published a plain-English version of all this on 14 July, which is the easier thing to read.
What it means for your venue
The clock is not running. These regulations only come into force when section 9(1) does, so their existence doesn't start anything. Any copy you see suggesting you're already inside a notification window is wrong.
What they do is close a genuine unknown. Until July, nobody could tell a venue how long it would have, and three months is a comfortable amount of time for a task that amounts to filling in a form about your address, your Schedule 1 use, and how many people you expect.
Notification is free and will be done through an online portal the SIA is still building. You cannot notify early, and there is no advantage in trying.
The one thing worth doing now is working out your number, because the form asks for the maximum you reasonably expect and the method you used to get there. That's the part that takes thought, not the submission.
