Getting your Martyn's Law tier classification wrong could be the difference between a £10,000 fine and an £18 million penalty – plus potential venue closure. With over 280,000 UK venues affected by this legislation, understanding your exact requirements isn't just important, it's business-critical.
Last week, we introduced Martyn's Law and its broad impact. This week, we're diving deep into the two-tier system that determines your specific obligations. Whether you're running a small restaurant or managing a major shopping center, this guide will help you calculate your requirements correctly.
Before we explore the tiers, you need to master the fundamental calculation that determines everything else: reasonable expected capacity .
It is about : The maximum number of people (staff + visitors) you can reasonably expect to be present at the same time during normal operations.
Restaurant Example :
Retail Store Example :
University Lecture Hall Example :
Shopping Center Example :
278,880 venues across the UK fall into this category, making it by far the most common classification.
Good news for Standard Tier venues : No physical alterations are mandated, but you must implement robust procedures.
Evacuation Procedures :
Invacuation Procedures :
Lockdown Procedures :
Communication Procedures :
While not required, many Standard Tier venues choose technology solutions to enhance their procedures:
Enhanced Tier venues face significantly more complex requirements, reflecting the higher potential impact of incidents at larger venues.
Enhanced Tier venues must implement everything from Standard Tier PLUS these additional requirements:
Monitoring Measures :
Movement Control Measures :
Physical Safety Measures :
Information Security Measures :
Several venue types have specific rules that override the standard capacity-based classification:
These require careful analysis:
Fire regulations focus on emergency egress; Martyn's Law considers normal operational capacity. These numbers are often very different.
Many venues calculate visitor capacity correctly but forget to include all staff members who might be present simultaneously.
Consider peak periods – a seaside venue might be Standard Tier in winter but Enhanced Tier during summer seasons.
Regular venue capacity determines your tier, even if you occasionally host larger events.
Don't assume your venue is exempt without careful analysis. Many seemingly obvious exemptions don't actually apply.
