Greater London was established in 1965 as an administrative unit covering the London metropolis. It was not defined as a county but had a two-tier structure, with the lower tier being the London boroughs.
Following the abolition of the Greater London Council (GLC) in 1986 the boroughs became single-tier authorities, but Greater London was still widely recognised, especially for statistical and mapping purposes. In 2000 however a two-tier structure was re-established when the new Greater London Authority adopted responsibility for a range of citywide policy areas.
There are 32 actual boroughs, with a status similar to metropolitan districts, and also the City of London, which is a City Corporation and has a number of additional roles. Boroughs are subdivided into electoral wards.
London borough names and codes are listed below. The listing shows the new 9 character ONS codes, that became operative on the 1st January 2011. For more information on the ONS 9 character coding, please refer to the Code History Database (CHD)
