Martyn’s Law is expected to come into force in spring 2027, so this autumn is a good time to start preparing...
The law is named after Martyn Hett, one of the 22 people who lost their lives in the Manchester Arena attack in 2017, and follows years of campaigning by his mum, Figen Murray. It’s about making sure venues are better prepared to keep people safe.
There are two tiers, based on how many people may be at a premises at the same time.
🔸 Standard tier, 200 to 799 people
🔸 Enhanced tier, 800 or more
Three things you can do now.
1️⃣ Note a realistic busiest-time headcount for each site
2️⃣ Work out who the responsible person is for each one
3️⃣ Think through how your team would evacuate, invacuate, lock down and communicate if an attack were suspected
