A calmer approach to Martyn's Law

Know exactly where your premises stand, and what to do next.

Gryphon helps organisations understand their obligations under the Terrorism (Protection of Premises) Act 2025, work through each requirement at their own pace, and maintain an evidencing record that reflects genuine preparedness.

Structured, plain-English, and built so that responsible persons can put the work down at the end of the day knowing the record is in good order.

Does the Act apply to you?

The Act covers a wide range of premises with a public-facing use, with proportionality applied throughout.

Local authorities

Mixed-tier portfolios under one account.

Hospitality & leisure

Venues where attendance and layouts shift.

Schools & places of worship

Standard tier with large, open-access crowds.

Healthcare & retail

Complex sites with high footfall and turnover.

Out of scope

Fewer than 200 expected

No statutory obligations. Good practice is still worthwhile.

Standard tier

200 to 799 expected

Notify the SIA. Procedures in place for evacuation, invacuation, lockdown, and communication.

Enhanced tier

800 or more expected

All standard tier duties, plus public protection measures, a documented record submitted to the SIA, and a designated senior individual.

The threshold is based on who you reasonably expect to be present. Gryphon's scope assessment walks you through it.

The weight responsible persons are carrying

Most organisations in scope are not security specialists. They are being asked to translate statutory guidance into something workable — and then keep it that way.

128 pages of guidance

Statutory text written for regulators, not for the people who actually run buildings.

Scope has nuance

Reasonable expectation, not maximum capacity. Easy to land on the wrong starting point.

Decisions need reasoning

The SIA considers why you decided something, not only what you decided.

Records drift

Layouts change, events change. A static document goes stale fast.

Deadlines creep up

Enhanced tier requires resubmission to the SIA within 30 days of a material change.

Staff change, knowledge doesn't transfer

Procedures documented in someone's head aren't procedures at all.

One platform, calmly maintained

Gryphon gives organisations the structure to work through each obligation in the right order — and the prompts to keep it current as things change.

Plain-English guidance

Every field explains what the law expects and what a thoughtful answer looks like.

Structured, section by section

The Act broken into ordered steps, so nothing is missed and nothing is rushed.

Reasoning captured

Decisions, intent, and timeframes recorded — not just ticks in boxes.

Stays current

Change detection, deadline tracking, periodic review prompts. Maintained, not filed away.

How it works

A guided process from first question to ongoing record.

1

Establish your position

Answer guided questions about your premises. Gryphon determines your tier and explains what applies.

2

Work through each requirement

Section by section, with context. Record what is in place, what is planned, and when.

3

Maintain it as a living record

Material changes flagged. Submission deadlines tracked. Reviews prompted. No last-minute scramble.

Why responsible persons choose Gryphon

The point isn't to look prepared. It's to genuinely be prepared — with a record that reflects the work done.

An evidencing record that holds up

Decisions, reasoning, and arrangements captured in one place — defensible if asked.

Preparedness as a process

Not a one-off document. A maintained record that moves with your organisation.

Steady progress, no panic

Build the record over months, calmly, instead of producing it in haste before an inspection.

Designed for the responsible person

For facilities managers and operations leads — no security-specialist background assumed.

Plans where there are gaps

Where something isn't yet in place, record what your organisation intends to do, and when.

Deadlines tracked for you

30-day resubmission windows and review cycles surfaced before they become a problem.

Show your organisation takes security seriously

Gryphon gives you a clear, structured record of your compliance activity — built around the obligations that matter under Martyn's Law.

Evidence that holds up

A documented record showing your organisation engaged seriously with its security responsibilities — exactly what the SIA expects.

Works alongside your advisors

Gryphon complements professional security advice. Use it alongside your consultants — it's the record-keeping layer they don't provide.

You stay in control

Your organisation owns the record. Gryphon supports the responsible person — structuring the process so nothing falls through the cracks.

Put down the spreadsheet. Pick up the platform.

The calmer route to compliance is also the more defensible one.
