List of Greater London boundary changes

This is a list of boundary changes occurring in the London region of England, since the re-organisation of local government following the passing of the London Government Act 1963.

Greater London was created by combining whole existing units of local government and it was anticipated that this might provide an arbitrary boundary in some places. The London Government Act 1963 Section 6 (4) provided a mechanism for communities on the edge of Greater London to petition for transfer to a neighbouring county. The legislation required the petition to be submitted between 1965 and 1970, to be signed by more than 300 local electors and for the area to be transferred to have no more than 10% of the borough's local electors. These were completed in 1969 as the transfers of Knockholt to Kent, and of Farleigh and Hooley to Surrey. Section 6 (3) of the act allowed for transfers between Greater London and neighbouring counties where there was consensus for the change between all the relevant local authorities. This power was used to exchange two islands on the River Thames that were connected to the river bank by bridges on the opposite side of the river to their respective counties. Thames Ditton Island was transferred to Surrey from Greater London and Platts Eyot was transferred the other way.

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.
