McMullen & Sons is an established brewery with almost 140 pubs and bars. These range from the stylish Baroosh bars to tenanted and managed premises throughout the Northern Home Counties. Stretching from Cambridge in the north, to Central London, and from Windsor in the west, to Chelmsford in the east, the premises cover a large area.


Barnet Lock & Security has provided comprehensive locksmith services for many years across the entire estate. This includes reactive maintenance works to fix anything from loose handles, broken toilet locks to new door closers. We supply, install and maintain safes to all the premises. Our emergency call-out service guarantees we are ready to respond 24 hours a day to any emergency across their portfolio.
