A Chief Fire Officer or CFO is the highest ranking Officer in the UK Fire & Rescue Service. There are currently 59 Chief Fire Officers serving in the United Kingdom in charge of County Fire Services.There is also a Chief Fire Officer responsible for the Ministry of Defence Fire Services which includes the Defence Fire and Rescue Service and the RAF Fire Service.Some UK Airport Fire Services also designate their seniors officers as CFOs. However, such officers rarely wear the rank markings of a Chief Fire Officer for many reasons.In Scotland CFO's were traditionally referred to as Fire Master, although this title has been replaced by Chief Fire Officer in most Scottish brigades.The rank is of equivalent stature to that of Chief Constable within the British Police Force, and Chief Ambulance Officer in the UK Ambulance ServiceUnder proposed changes Chief Fire Officers were to be renamed Brigade Managers in line with modernisation directives issued by the Department for Communities and Local Government.
