Quick answers
What is the difference between Standard Tier and Enhanced Tier?
Standard Tier (200 to 799) focuses on documented procedures, staff training, and emergency planning. Enhanced Tier (800 and above) adds a formal terrorism risk assessment, security plan, designated senior individual personally accountable, and reasonably practicable physical protective measures.
How is capacity measured?
Maximum people your venue can hold at any one time, including staff. If your venue can hold 200 people at peak, you are in scope regardless of your average occupancy.
When does Martyn's Law come into force?
Enforcement begins in April 2027. Royal Assent was granted in April 2025. The SIA is the regulator.
Can my venue tier change?
Yes. If you increase capacity through expansion, refurbishment, or a change in licensed numbers, you may move from one tier to another. Review your tier annually.
