. In the distribution of seats in effect from 1974 to 1983 the official name of the Greater London seats included a London Borough prefix. In most cases this is not used in the article names. There were also instances when a distinctive constituency name had, at different periods, been prefixed by different borough names. In those cases the distinctive constituency name alone is usually used in the article name. See the notes column for further details. Key to abbreviations:- * (Type) BC Borough constituency, CC County constituency, UC University constituency. * (Administrative County in Notes) B shire county of Berkshire, GL Greater London (from 1965), H administrative/shire county of Hertfordshire (from 1965), L administrative county of London (1889–1965), M1 historic county of Middlesex (to 1889), M2 administrative county of Middlesex (1889–1965), S administrative/shire county of Surrey (from 1965).

Constituencies wholly or predominantly in the historic county

Notes:- * ¹ Not technically part of the administrative county of London, but it was surrounded by it and was not part of any other administrative county. * ² This constituency is strictly the South Poplar division of Poplar. As 'Poplar South Poplar' would include the borough name twice, the official name of the constituency is referred to as 'South Poplar'. The existing article calls the seat 'Poplar South' (which is in the usual form for a borough constituency, but does not match the unusual official name of the seat). A redirect exists from the official name to the article name.

Constituencies mostly in another historic county

Note:- * ¹ The constituency is in Greater London and mostly forms part of the historic county of Hertfordshire. The seat was created in 1974, but it was not until the 1997 redistribution that it included part of the historic county of Middlesex.
