Governance Biggleswade was a constituent part of and gave its name to one of the Hundreds of Bedfordshire from Anglo-Saxon times until the 19th century. From 1892 the town was governed by a Local Board, which became Biggleswade Urban District under the Local Government Act 1894. This council met at Biggleswade Town Hall until 1926, then shared other premises in the town before acquiring Stratton House in 1952. The Urban District Council was abolished in 1974 when most of its functions were subsumed into Mid Bedfordshire District Council under the Local Government Act 1972, the remainder passing to the newly formed Biggleswade Town Council. In 2009, the District and County Councils were replaced by the Central Bedfordshire Unitary Authority. Biggleswade Town Council's responsibilities include car parks, allotment gardens, cemeteries (Drove Road and Stratton Way), play and recreation areas and the Orchard Community Centre. Planning applications referred from Central Bedfordshire Council are considered and objections can be raised. Biggleswade divides into three electoral wards: Ivel for the north, Holme for the south-west, and Stratton for the south-east. Voters elect five councillors per ward, for four-year terms. They in turn elect annually a Town Mayor. Town Council funds come from a precept agreed with Central Bedfordshire Council. Council meetings since 2006 have been held in a council chamber in the former magistrates' court in Saffron Road. Central Bedfordshire Council is responsible for Biggleswade's social care homes, public library (Chestnut Avenue), roads, refuse, Saxon Pool and Leisure Centre (managed on its behalf by SLL), non-academy schools, social services and planning.
