Share999 · Martyn’s Law
Martyn’s Law is coming. Here’s how your premises meets it.
If 200 or more people could be on your premises at once, the Terrorism (Protection of Premises) Act 2025 applies to you. Share999 gives you the procedures, the signage, the evidence and the means to tell everyone what to do — your staff work from a link, your visitors scan a sign, and nobody downloads an app.
Expected to come into force in spring 2027 · Regulated by the Security Industry Authority · Final statutory guidance due autumn 2026
Step one
Which tier are you in?
Everything else follows from one number: how many people could reasonably be on your premises at the busiest time.
Start with the question you’re actually asking
How many people could be on your premises at the busiest time?
Count everyone — staff, visitors, audience — at your busiest reasonably expected moment, not the fire capacity.
What the Act asks of you
Procedures first. Products second.
The government has been clear that you don’t need to buy specialist products to meet the duty. What you need is to be able to do four things, to have staff who know how, and — in the enhanced tier — to document it.
Standard tier · 200 to 799 people
Notify the SIA and have procedures in place
Procedures for evacuation, invacuation, lockdown and communication, so far as is reasonably practicable — and staff who would carry them out must know them. Pubs, theatres, halls, places of worship, shops and hotels mostly sit here. Schools and childcare stay in this tier whatever their size.
Enhanced tier · 800 or more people
All of the above, plus measures you document
Public protection measures that reduce vulnerability and harm, a written assessment of those measures provided to the SIA, and a designated senior individual responsible for compliance. Arenas, stadiums, large venues, shopping centres and qualifying events sit here.
How Share999 gets you there
From one number to a documented procedure in an afternoon.
You configure your premises once. The procedures document, the signage, the staff briefing and the drill evidence all come out of that. If something happens, the same setup becomes the way you tell everyone what to do.
1
Set up your premises
Name, capacity, entrances and exits, the spaces you’d move people to, the points you’d secure, who’s responsible, and your staff — added by mobile number. About twenty minutes.
2
Your procedures document
Generated from what you entered, in the statutory guidance’s own headings: the four procedures, who is responsible, how staff are told, how the public are told. Ready to show an inspector, an insurer or a licensing officer.
3
Signage that puts visitors on the list
Print a QR sign for each entrance, refuge space and public area. On a normal day it’s your safety notice. During an incident it’s the live instruction for that spot — and anyone who scans is on your visitor list, with nothing to install.
4
Brief your staff by text
Each member of staff gets a text with a link to your procedures and confirms they’ve read it. That confirmation is your briefing record. New starter next month? Add a number.
5
Drill, and keep the evidence
Switch to drill mode, press a procedure, watch acknowledgements come back. The drill log — who, when, how long — is the evidence that your procedure works. Share999 reminds you when the next one is due.
6
If it happens: three buttons and All Clear
Evacuate. Invacuation. Lockdown. One tap tells every member of staff and every visitor who scanned in what to do, at the location they’re in. All Clear when it’s over. The police can see the same picture.
What you’ll be holding
Compliance you can put on the table.
Every artefact the Act or the guidance expects is a view of your setup or a record of using it. You never write a document. You configure a premises, and the documents follow.
Procedures document
Your public protection procedures, in the guidance’s headings.
SIA notification details
The premises and responsible-person details, assembled and ready to submit.
Signage pack
A printable QR sign for every entrance, refuge space and public area.
Staff briefing record
Who has confirmed they know the procedures, and when.
Drill log
Every drill, with acknowledgement times — the evidence that it works.
Annual review
Prompted when it’s due, recorded when it’s done.
No app for visitors. No hardware.
Reach the people who aren’t on anything.
Most of the people on your premises are visitors. They haven’t installed your app and never will. Share999 reaches them through the premises itself — and each channel works on its own if the others fail.
QR signs
Scan to see the live instruction for that spot, and be counted there.
Guest Wi-Fi
Anyone on your network sees the instruction on the sign-in page.
Bookings and tickets
Anyone whose number you already hold gets a text, and can reply that they’re safe or need help.
Screens
Bar screens, foyer displays and menu boards switch to the instruction.
The register shows who is accounted for, who isn’t, and how many people are present that you can’t yet name — never a false all-clear.
What it costs
Priced by how many people you can reach. Not per seat.
Martyn’s Law is about the public on your premises, so Share999 Instant is priced on the number of people you can connect — staff and visitors together — for a year, with unlimited alerts and drills, the signage, the document and the evidence included. Prices in GBP. Emergency services are always free.
Up to 1,000 people
£1,000 a year
A pub, a church, a village hall, a small theatre, a clinic. Where most standard-tier premises sit.
Up to 2,500 people
£2,250 a year
A larger venue, a school, a museum, a community centre, a busy place of worship.
Up to 5,000 people
£4,000 a year
A hotel, a conference centre, a large store, a big church. Where the enhanced tier usually begins.
Larger venues and estates: up to 25,000 people from £10,000 a year, up to 100,000 from £30,000. Running a one-off event rather than a premises? Instant is also priced per attendee, per day.
Enhanced tier and estates
Responsible for more than one premises?
Arenas, stadiums, shopping centres, hotel groups and festival sites get the same product with zones and sectors, ticketing and property-system integrations, a control-room view, the documentation the enhanced tier has to submit, and a shared picture with the police. One standard across every site.
Emergency services
Free for police, fire and ambulance. Always.
When a premises shares its picture, the control room sees the procedure in force, who is accounted for and where — the shared situational awareness JESIP asks for, and the thing the Manchester Arena Inquiry found missing. Emergency services participate at no cost.
Questions responsible people ask
Straight answers.
Do I have to buy software to comply?
No. The Home Office has been explicit that premises don’t need to spend money on products or consultants, and neither the government nor the SIA endorses any product. What you must be able to do is carry out the four procedures and, in particular, tell everyone present what to do. Share999 is one way to do that and to evidence it.
When does this start?
The Act received Royal Assent on 3 April 2025 with an implementation period of at least 24 months, so it is expected to come into force in spring 2027. The SIA’s guidance duties began in June 2026 and final statutory guidance is due in autumn 2026. The exact commencement date will be confirmed in advance.
Do my staff need to install an app?
Not to receive alerts. Staff get a text with a link; visitors scan a sign. The person who raises the alert — usually you, or whoever is in charge that day — signs in to Share999 on any phone, tablet or computer, the same way you’d sign in to online banking, and can keep it on their phone’s home screen so it’s one tap away. There is nothing to download from an app store.
What about the people we don’t know — customers, audience, congregation?
That’s who this is built for. They’re reached through the signage, your guest Wi-Fi, any booking or ticket list you already hold, and your screens. Anyone who scans is on the list.
We’re a school. Does this apply to us?
Schools and childcare premises where 200 or more people could be present fall in the standard tier regardless of size.
What does it cost?
Share999 Instant is priced by how many people you can reach in a year: up to 1,000 people is £1,000, up to 2,500 is £2,250, up to 5,000 is £4,000, with larger plans for big venues and estates. Everything on this page is included. Emergency services are free.
