Martyn’s Law compliance support
Martyn’s Law compliance support helps venue and event teams organise the operational work that may be needed under the Terrorism (Protection of Premises) Act 2025. SSS can support agreed procedures, training records, operational documentation and security delivery through the SSS Application. SSS does not decide whether a premises or event is in scope, determine its legal tier or certify legal compliance.
Official guidance says the substantive duties have not yet commenced and the SIA currently expects commencement in spring 2027, with the exact date to be confirmed. The preparation period is the opportunity to identify the Responsible Person, understand the likely scope and make procedures workable before the duty comes into force.
London venue & event security
General operational information for London venues and events—explaining the current position, the Responsible Person’s role and the practical records SSS can support where agreed.
A measured response
Martyn’s Law is the name commonly used for the Terrorism (Protection of Premises) Act 2025. It is intended to improve protective security and organisational preparedness at certain publicly accessible premises and events. For London operators, the priority is not a generic compliance exercise; it is knowing who has responsibility, what procedures are needed and whether the people who will deliver them are ready.
For SSS clients, the SSS Application can bring agreed operational information into one client environment. It can record a client’s working scope assessment, agreed procedures, training records and security operations. It does not make a legal determination of scope or tier, and it does not certify legal compliance.

Understanding likely scope
Whether a particular premises or event is in scope depends on the full statutory tests. For premises, those include the building, use, expected simultaneous attendance including staff, and exclusions. Qualifying events have separate public-access and entry-check tests. The Responsible Person should assess each site against current official guidance; capacity alone is not a legal determination.
Usually standard tier
Usually, qualifying premises with 200–799 individuals, including staff, will be standard tier. When the Act comes into force, the Responsible Person will need to notify the SIA as prescribed and, so far as reasonably practicable, have appropriate public-protection procedures in place.
Usually enhanced tier
Usually, qualifying premises with 800 or more individuals, including staff, will be enhanced tier. Qualifying events have separate tests and are subject to enhanced-tier requirements. When the Act comes into force, enhanced-tier duties include appropriate measures, an up-to-date statutory document and submission of that document to the SIA.
Some in-scope places of worship and childcare, primary, secondary and further-education premises remain standard tier even at 800 or more. The Act also sets separate qualifying-event criteria, including public-access, entry-check, location and exclusion conditions. A security provider can support delivery, but legal responsibility remains with the Responsible Person.
Included for SSS clients
The SSS Application brings operational information into one transparent client environment. It does not replace the Responsible Person’s legal duties; it helps keep the practical foundations visible, current and accountable.
Record the client’s working, site-specific scope assessment and the information considered in operational planning. The Responsible Person must verify the complete statutory tests and current official guidance.
Maintain visibility of the procedures agreed for the venue as conditions, risks and operating arrangements evolve.
Where used in the agreed client configuration, the environment can hold current training and site-instruction records for operational oversight. A training record alone does not determine statutory adequacy or legal compliance.
Client access can support visibility of agreed rotas, licence-status records, incident reports and operational information. Those records support oversight; they are not a legal-compliance certificate.
Included, not upsold. The SSS Application is provided as standard with every SSS contract, with no separate platform licensing or implementation charge.
Calm presence. Commanding results.
Written procedures only matter when the people on site can recognise the situation, communicate decisively and follow the plan without compromising the customer experience.
SSS combines visible operational discipline with the composed, professional service expected at premium hospitality venues, events and private locations across London.
There is no responsible one-size-fits-all checklist. SSS begins with the operational reality of your venue, event or portfolio.
Identify the operating model, attendance profile, likely tier and the person who controls the site or event.
Establish the practical procedures and proportionate security arrangements that make sense for the venue.
Ensure security personnel have current, site-specific instructions and training completion is recorded.
Keep documentation, rotas, incidents and operational updates visible through the SSS client environment.
The Responsible Person
The Responsible Person is generally the individual, company or organisation that controls the premises or qualifying event. They retain legal responsibility under the Act and should use the latest official guidance and appropriate professional advice for their circumstances.
Special Service Security
SSS can support planning, site readiness, staffing and the ongoing delivery of security arrangements. We do not take over the Responsible Person’s legal responsibility or certify a venue as legally compliant.
The operational essentials
When the Act comes into force, the statutory guidance identifies four public-protection procedures for the Responsible Person to consider. They must be site-specific, proportionate and designed so staff are not required to compromise their own safety.
Move people away from the premises or event area safely and decisively.
Move people to a safer area inside the premises or event site.
Prevent individuals entering or leaving where that is the appropriate site-specific response.
Provide clear, timely instructions to staff, guests and relevant responders.
Questions answered
The answers below are general information only. Decisions about a particular venue or event should be based on the current statutory guidance and the organisation’s own circumstances.
No. The Act has received Royal Assent, but its statutory duties have not yet commenced. The SIA currently expects commencement in spring 2027 and will confirm the date ahead of time.
No. Scope depends on the detailed statutory tests, including the building, use, expected simultaneous attendance including staff and exclusions. Some premises also have tier exceptions. Operators should assess their own site using current Home Office, SIA and ProtectUK guidance.
Not necessarily. The Act does not create a universal requirement to employ security personnel. Any procedures and protective measures should be appropriate and reasonably practicable for the particular venue or event.
No. A security company can support delivery, but the Responsible Person retains the statutory responsibility assigned by the Act.
The SSS Application is included as standard with every SSS contract, without a separate platform licence or implementation charge. Its records support operational oversight and do not certify legal compliance.
