List of boundary changes in Yorkshire and the Humber

This is a list of boundary changes occurring in the Yorkshire and the Humber region of England, since the re-organisation of local government following the passing of the Local Government Act 1972.

Initial creation
When the Local Government Act 1972 was passed there were still some details left to be decided, the Local Government Boundary Commission for England's first work was to clarify these details.

Principal Area Boundary Reviews
The Local Government Boundary Commission for England (or LGBCE) was established by the Local Government Act 1972 to review the administrative boundaries of every local authority in England. Between 1974 and 1992 they completed a series of Principal Area Boundary Reviews; reviewing the administrative boundaries of local authorities at their request.

Mandatory Reviews of non-Metropolitan Counties, Metropolitan Districts and London Boroughs
In 1985 they began the first full administrative review of all non-metropolitan counties. Their reviews of metropolitan counties and Greater London began in 1987 and both reviews were completed in 1992.

Initial creation
When the Local Government Act 1972 was passed there was not sufficient time to draw up proper electoral boundaries for the new county and district councils, so a temporary system was quickly put in place, intended to only be used for the first elections in 1973.

First periodic review
The Local Government Boundary Commission for England (or LGBCE) was established by the Local Government Act 1972 to review the electoral boundaries of every local authority in England. In 1974 they began the first full electoral review of all metropolitan and non-metropolitan districts, completing it in July 1980. Their reviews of the county councils were completed in 1984.

Second periodic review
The Local Government Act 1992 established the Local Government Commission for England (or LGCE) as the successor to the LGBCE. In 1996 they began the second full electoral review of English local authorities. On 1 April 2002 the Boundary Committee for England (or BCfE) took over the functions of the LGBCE and carried on the review, completing it in 2004.

Further electoral reviews by the LGBCE
The Local Government Boundary Commission for England (or LGBCE) was established by the Local Democracy, Economic Development and Construction Act 2009 on 1 April 2010 as the successor to the BCfE. It continues to review the electoral arrangements of English local authorities on an ‘as and when’ basis.
