What venues in Kensington and Chelsea need to do

Standard tier (200 to 799 people): have procedures for evacuation, invacuation, lockdown and communication, make sure staff know what to do, and notify the SIA. There is no legal requirement for building works. See the four procedures explained.

Enhanced tier (800 or more): all of the above, plus documented public protection measures provided to the SIA and, for organisations, a designated senior individual. See enhanced tier duties.

The Act applies across England, and the Security Industry Authority (SIA) regulates it. Your council remains your licensing authority, but it is not the Martyn's Law regulator.
