Terrorism (Protection of Premises) Act 2025
What will Martyn's Law cost you?
Start with the fact most pages skip: the duties in Part 1 of the Act are not in force. The Home Office has commenced only the guidance provisions so far, and no date has been appointed for the requirements themselves. When they do bite, cost turns on tier (200 to 799 is standard, 800 or more is enhanced), how many premises you run, and how much of your existing fire evacuation and security work can be adapted rather than rebuilt. Tell us about your premises and specialists will quote you.

What drives the cost of Martyn's Law compliance
Last updated
There is no published price for Martyn's Law compliance, and no statutory fee, so this table sets out what actually moves a quote instead of inventing a range. The tier, the number of premises and how much existing work can be reused are the three factors that decide almost everything.
Compiled from the Terrorism (Protection of Premises) Act 2025 and the Home Office statutory guidance published 7 August 2026, as at the updated date above. We publish no price range because the duties are not yet in force, no regulator fee exists, and quoted prices vary too widely by premises type and scope to state honestly. The statutory maximum penalties quoted elsewhere on this page come from section 18 of the Act.
| Cost driver | Why it moves the price | What to ask for in a quote |
|---|---|---|
| Which tier the premises fall in | Standard duty premises (200 to 799) need public protection procedures only. Enhanced duty premises and qualifying events (800 or more) also need public protection measures, a written compliance document sent to the SIA, and a designated senior individual | A fixed price for tier assessment, stated separately from any implementation work |
| How the capacity figure is evidenced | The number must include staff and must satisfy the SIA as a reasonable method. Sites with no fire safety occupancy figure, no ticketing data and no counting system pay for the assessment work to establish one | Whether the assessment produces a written, evidenced figure you can hand to the regulator |
| Number of premises, and whether they are alike | A single template rolled across 20 similar sites costs far less per site than 20 bespoke assessments. Premises within premises, such as units in a shopping centre, need co-ordination between responsible persons | A per-site rate for sites two onward, not a flat multiple of the first |
| How much existing work can be adapted | Evacuation procedures usually already exist under fire safety law. Invacuation, lockdown and communication procedures often do not. Adapting beats writing from scratch | An explicit gap analysis against your current fire and security documents before any drafting |
| How staff training is delivered | The Act contains no statutory training requirement. The guidance says it is not mandatory to pay for third party training, and gives briefings, e-learning, induction sessions and shadowing as acceptable forms | A price for briefing material your own managers can deliver, alongside any tutored option |
| Physical measures, enhanced tier only | Monitoring, movement control, physical security and information security measures apply to enhanced duty premises and qualifying events. Standard tier premises are not required to install equipment | Confirmation in writing that any equipment quoted is required by your tier, not simply recommended |
| Timing against commencement | The Part 1 duties are not in force and no commencement date has been appointed. Buying an implementation programme now is a choice about readiness, not a legal deadline | A quote that separates work you need before commencement from work you need after |
- Premises are standard duty under the Terrorism (Protection of Premises) Act 2025 where it is reasonable to expect 200 or more individuals present at the same time from time to time, and enhanced duty at 800 or more.
- The Act contains no statutory requirement for the responsible person or staff to complete specific counter terrorism training, and the Home Office statutory guidance states it is not mandatory to pay for third party training.
- The maximum non-compliance penalty is £10,000 for a contravention relating to standard duty premises, and the greater of £18 million or 5% of qualifying worldwide revenue for enhanced duty premises and qualifying events.

Common questions
How much does Martyn's Law compliance cost?
There is no published price and no statutory fee, so treat any single figure with suspicion. Cost turns on your tier, the number of premises, whether your capacity figure is already evidenced, how much of your existing fire evacuation work can be adapted, and whether you are enhanced tier and therefore in scope for measures and a compliance document. Get quotes against a defined scope rather than a generic package.
What capacity puts my premises in scope of Martyn's Law?
200 or more individuals, including staff, reasonably expected on the premises at the same time from time to time puts qualifying premises in the standard tier. 800 or more puts them in the enhanced tier. A qualifying event needs 800 or more plus access controls such as ticketing.
Is Martyn's Law in force?
Not the duties. Only the guidance provisions have been commenced, section 27 on 10 April 2026 and parts of sections 12 and 18 on 15 June 2026. Sections 5 to 10, which impose the requirements, await a commencement order under section 37(2).
Do I have to notify the SIA about my premises?
Yes, once section 9 is in force. The Notification Requirements Regulations 2026 give responsible persons for qualifying premises three months from commencement day to notify the Security Industry Authority, and 14 days for qualifying events, with 28 days to correct information that stops being accurate.
Does Martyn's Law apply to a place of worship with 1,000 people?
Yes, but in the standard tier. Schedule 1 paragraph 9 provides that where the relevant use is communal worship or other communal religious practice, the premises are standard duty premises regardless of how they would otherwise be treated. The same rule applies to childcare settings and primary and secondary education institutions.
Is this quote service really free?
Yes, free to you and with no obligation to accept any quote. We pass your details only to relevant security and compliance specialists, who quote you directly. We may receive a fee from those providers, which is how the service is funded.
