Hertsmere Borough Council is the local authority for the Hertsmere non-metropolitan district of England, the United Kingdom. Hertsmere is located in the south of Hertfordshire, in the East of England region.
The Council itself is based in Borehamwood, the largest settlement in the district,. Other towns in the borough include Bushey, Elstree, Radlett and Potters Bar.
The district was formed on 1 April 1974, under the Local Government Act 1972, by a merger of the former area of Bushey Urban District and Potters Bar Urban District with Elstree Rural District and part of Watford Rural District (the parish of Aldenham).
The name "Hertsmere" was invented for the new district by combining the common abbreviation of "Hertfordshire" ("Herts") with "mere", an archaic word for boundary. The name is doubly appropriate as the district straddles the historic county boundary between Middlesex and Hertfordshire and forms the administrative boundary between Hertfordshire and Greater London. The name is reflected in the council's coat of arms, which shows a hart upon the battlements of a boundary wall.
The district was awarded borough status by Royal Charter in 1977.
The borough was originally in the Metropolitan Police District, despite being outside the modern Greater London boundaries. It was transferred to Hertfordshire Constabulary in 2000.
Hertsmere is the location of Elstree Studios, which produces such shows as Who Wants To Be A Millionaire, Dancing on Ice, and is the location for the Big Brother house.
Hertsmere is also the location for BBC Elstree, the site of EastEnders, and formerly the home to Top of the Pops, before its move to BBC TV Centre.
The area was also home to other TV and film studios, including MGM, until this was demolished for residential development, and is now an area called Studio Way.
