Introduced daily on 3 May 1950 as part of the post-war improvement programme, the 264 initially operated from Hersham and Walton via Upper Halliford to French St, Sunbury.  The Upper Halliford section lasted only to 10 Oct 1950, when the route was diverted via Sunbury Village and Green Street.  The route was operated by Kingston garage and, because (like the 218) it crossed the weak Walton Bridge, used 1T1s. 

A year on, in June 1951, the route was extended along the 216 routing to Kingston.  In February 1957, the route was realigned again, away from Sunbury Village and back through Upper Halliford, but this time running up Windmill Road to Staines Road West, then straight along past Sunbury Clock Tower (now the junction at the end of the M3 and renamed Sunbury Cross) along Staines Road.  The Sunday service was withdrawn in November 1958.

Meanwhile, the route and its 1T1s were transferred to Norbiton when that garage opened in May 1952, until the replacement of the bridge at Walton in January 1953 enabled the 1T1s to be withdrawn and replaced by 14T12s and 10T10s.  These in turn were replaced by TDs in 1954/5.

Before Kingston received its first RFs in July 1959, Norbiton lost its TDs in favour of the RF, using buses made surplus after reductions following the 1958 strike and also the conversion of Dalston's 208^A to the double deck 178.  The 264 and 206 were converted on the same day, 10 June 1959.

As part of the allocation shuffle on Fulwell's first day of bus operation, 9 May 1962, the 264 allocation was moved to Kingston, apart from part of the Saturday schedule, which stayed at Norbiton.  This change reversed a year later when the route returned to Norbiton, only to change again in 1966 when the whole route moved to Fulwell on conversion to one-man operation on 23 January.

From here on, the route settled down, with no changes for over 10 years until July 1976, when it became the first of the Kingston area routes to lose its RFs in favour of Bristol BLs.  These lasted for less than 18 months before the route was withdrawn on 28 January 1978, before the Kingston RFs themselves finished.
