Everyone knows what to do

Volunteers, staff and hirers each get a short briefing for your building on their phone, and confirm they've read it. No app needed, no password.

A made-up example. Real briefings are written from your own answers, and the details that need to stay private, like where keys are kept, go only to the people who need them.

Your plans in about 30 minutes. Four steps.

Most of the time is answering questions about a building you already know.

  1. 12 minutes

    Check your venue

    Four questions tell you whether Martyn's Law applies and which tier you're in. Free, with no email needed.

  2. 2About 20 minutes

    Tell us about your building

    Your doors, rooms, where people could gather safely, and who has keys. Plain questions, with examples.

  3. 3About 10 minutes

    Approve your plans

    hailo drafts your four plans in plain English, written for your building. Edit anything, then approve them.

  4. 4Ongoing

    Brief your team

    Volunteers, staff and hirers get a short briefing by link or QR code and confirm on their phone.

We remind you. When a volunteer joins, a keyholder leaves, a plan changes or the yearly review is due, hailo tells you and re-briefs the people it affects.

Why not just use the free template? You can. Here's what hailo adds.

The SIA is expected to publish templates in early 2027. A template is a blank form. hailo fills one in for your building, briefs everyone and keeps it up to date.

Time to plan your procedures

Does it apply to you? Find out now.

Four questions, an answer straight away, and no email needed.

  1. Count everyone, including staff and volunteers. Think of festivals and big services, quiz nights, big matches or parties, not an ordinary day.

  2. 3. Is the building mainly used for any of these?

    Its main use, not something it hosts now and then. A hall with a weekly service or playgroup is still mainly a hall. Leave them blank if none is.

  3. 4. Do you ever hold events where 800 or more people are there at once?

    Even once a year counts, such as a festival, a fair or a big match.

Your answers stay on this page. Nothing is sent or stored.

Questions committees actually ask

Read the guides

Does Martyn's Law apply to us?

It applies to a building where 200 or more people, including staff and volunteers, can reasonably be expected at the same time, used for things like worship, entertainment, food and drink, sport or community events. Our free scope check tells you in two minutes.

How do we count to 200?

Count the most people you'd reasonably expect in the building at the same time on your busiest occasions, including staff and volunteers. Think of festivals and big services, quiz nights or big matches, not an ordinary day.

Do we legally have to write our plans down?

Not at the standard tier: the law asks you to have the procedures in place, not a document. But written plans are how you brief people consistently and show the SIA what you've done, which is why hailo writes them for you.

Why pay when the SIA's template will be free?

The template is a blank form. hailo fills it in for your building, briefs every volunteer, member of staff and hirer, and keeps it current when people and plans change.

How much of our time will it take?

The Home Office estimates that planning the procedures takes about 9 hours of managers' time, and puts the standard tier's cost at about £330 a year, almost all of it people's time rather than money. With hailo it's about 30 minutes of questions about your building, then a few minutes whenever things change.

Does hailo make us compliant?

hailo helps you prepare, and keeps the evidence of what you've done. Only the regulator can judge whether a venue meets the law, and the responsibility for your venue stays with you.

What do volunteers need to do?

Open a short briefing on their phone, read what to do in each situation, and tap to confirm. It takes a few minutes, and there's nothing to install.

Do we need security equipment or staff?

No. The standard tier doesn't require security staff, bag searches, CCTV or any equipment. It's about plans and people knowing them.

What happens if we do nothing?

Once the duties start, expected in spring 2027, the SIA can give advice and, where needed, issue penalties. For the standard tier the maximum penalty is £10,000, and up to £500 a day if a venue ignores an order to put things right.

Do our hirers need to know about it?

Yes. When you hire out your building, you stay the responsible person. The Home Office's guidance says to explain to each hirer what's expected of them, and to be able to show the SIA that you did. hailo sends each hirer a short briefing for their booking and keeps a dated record of who confirmed it.

Who is the SIA and how do we tell them?

The Security Industry Authority is the regulator for Martyn's Law. The responsible person must tell it about the venue; the SIA will publish how, and hailo will walk you through it.

Who is behind hailo?

hailo is made by SimpleKPI Ltd, a UK software company founded in 2007. It is independent and not endorsed by the Home Office or the SIA.

Can we cancel?

Yes. Plans are paid yearly per venue, from £39 plus VAT, and you can stop renewing at any time. The emergency steps your door posters link to stay online, so volunteers are never left without the plan.
