Hi All

In a multi occupied premises consisting of multiple units rented out to individual businesses would you need compartmentation between each unit? And if so how many minutes?

The purpose groups are 3 and 6. The units are not ancillary to each other and are totally independent businesses but share common escape routes and fire detection system.

Many thanks.

There should be 60 minute separating occupies 

However, if an existing building with a common alarm system and simultaneous evacuation you are fine. A new build would indeed require 60 minutes and usually then doesn't need linked alarms.

Thanks both for your help. It is an existing building that has undergone change over the years, there is indeed a common alarm system and simultaneous  evacuation. I suppose the most important element is ensuring all shared common escape routes have a minimum of 30 minutes separation?

Yes, at least a notional 30 minutes usually
