Why we built this
Last reviewed: June 2026
martynslaw.app is built and run by We Share The Same Sky Ltd, a Birmingham company — by people who run a real, publicly accessible venue and face the same preparation for Martyn’s Law as everyone else. We built the tool we wanted ourselves: a plain-English way to work out whether a venue is in scope, which tier applies, and what to actually do about it — without paying for a certificate that nobody can issue.
That operator background is the whole point. We are not a security consultancy selling assessments; we run a venue, so the checklists are written for the person actually doing the work — the duty manager, the licensee, the events lead — not for a compliance auditor.
How we keep it accurate
Everything we publish is grounded in primary sources, and we say which one each statement rests on. We track the official sources daily and update the site when they change. The sources we work from:
- The Act itself
Terrorism (Protection of Premises) Act 2025 — the full text on legislation.gov.uk.
- Home Office statutory guidance
The Home Office's own factsheets and statutory guidance for the Act, on gov.uk.
- ProtectUK
Counter Terrorism Policing's guidance hub for protective security and Martyn's Law.
- Security Industry Authority (SIA)
The regulator that will oversee the Act's requirements.

What this is — and what it is not
martynslaw.app is a preparation and document-management tool. It is not legal advice, not official guidance, not official certification, not SIA approval and not a guarantee of compliance. The responsible person must review and approve all documents before use.
