What you'll have to tell the SIA when you register
In short
The information a standard-tier notification must contain is fixed by law, not left to a form-builder. It covers who is responsible for the premises, how many people you expect at once and how you worked that out, any relevant licences, and a handful of yes/no facts about the building. The SIA's online portal is not live yet, and no date has been set for when notification duties begin.
Key points
The field list comes from a statutory instrument — the Notification Requirements Regulations 2026 — not from guesswork or a GOV.UK guidance page.
It covers who is responsible, contact details, the greatest number of people expected and the method used to work that out, any licences held, and a few other premises facts.
You must confirm you understand that knowingly or recklessly giving false or misleading information is a criminal offence.
Deadlines run from "commencement day", which has not been fixed, so no calendar date can be given yet.
Notification will be made through an SIA online portal, which is not open.
What the notification will cover
The regulations require a standard-tier premises notification to answer a set list of questions, grouped broadly as follows:
Who is responsible. The name and contact details of each person or organisation responsible for the premises under the Act, and the same for anyone else who has any control over them, or who has to co-ordinate with the responsible person.
The premises themselves. The postal address including postcode, whether it is a group of buildings and how many, whether it forms part of a larger premises, and whether there is any seating adjoining the premises — on the pavement or road outside, for example.
The numbers. The greatest number of people reasonably expected at the same time, and — separately — the method you used to work that figure out.
Advertising and licences. Any website or social media accounts used to advertise the premises, and whether you hold, have applied for, or have given notice of an alcohol licence (including a temporary event notice), an entertainment licence, or a sports-ground safety certificate.
Who is submitting it. If you are not the responsible person yourself, your name, role, relationship to the responsible person, and confirmation that you are authorised to act for them.
A statutory confirmation. That you understand knowingly or recklessly giving false or misleading information to the SIA is a criminal offence under section 25 of the Act — a confirmation about a crime, not a routine tick-box.
Regulation 2(4) is also specific about what "contact details" means for these purposes: a telephone number, an email address, and a postal address including postcode — but it adds "where that information is available", so a committee with no telephone line can still notify, and a missing number does not make a notification incomplete.
The deadlines, and why we can't give you a date
Regulation 3 sets three deadlines. If you become responsible for qualifying premises, you must notify by the later of: three months from "commencement day", or 28 days from the day you became responsible — whichever is later, not "three months, then 28 days" as a sequence. The same "later of" rule applies if you cease to be responsible. If information you've already given the SIA stops being accurate, you have 28 days from the day it first stopped being accurate — not from when anyone notices or updates a record.
The catch is that "commencement day" — the day the notification duty itself starts — has not been set. The explanatory memorandum to these regulations says the duty "will not come into force until after 3 April 2027 at the earliest". The SIA has said it expects the Act to come into force in spring 2027 and will confirm the exact date nearer the time. Until then, any deadline that runs from commencement day cannot be turned into a calendar date, and nobody should tell you otherwise.
Common questions
- Is the SIA's notification portal open now?
No. It is not live. It will be reached through GOV.UK, with volunteer testing expected from early 2027.
- Do we need to notify the SIA right now?
No. The notification duty has not commenced, and no date has been fixed. When it is, we'll update this guide.
- What if our details change after we've notified?
You have 28 days to correct the SIA's records — but the clock starts on the day the information first stopped being accurate, which may be well before you noticed or updated anything.
