 Central government maintains national standards and a body of independent advisers through the Chief Fire and Rescue Adviser, which was created in 2007, while Her Majesty's Inspectorate of Constabulary and Fire & Rescue Services provides direct oversight.The devolved government in Scotland has a similar agency, HMFSI Scotland.Firefighters in the United Kingdom are allowed to join unions, the main one being the Fire Brigades Union, while chief fire officers (the heads of the various FRS) are members of the National Fire Chiefs Council (formerly the Chief Fire Officers Association), which has some role in national co-ordination.
