Route 24 dates back to 1910, when it ran between Hampstead Heath and Victoria station. In August 1912 it was extended to Pimlico and has continued in that form until the present day, making this the oldest unchanged bus route in London. Thirty-three Daimler double-decker buses with 34 seats were allocated to route 24, now running between Pimlico and Hampstead, with the fleet name "British" painted in green livery. These buses were running from Camden Town (AQ) garage until they were replaced by AEC NS-Type buses in 1927. Thirty-three NS-type buses were used on route 24 until 1934.
Originally, the route was operated by the London General Omnibus Company, and later the British Automobile Traction Co until September 1933, when the London Passenger Transport Board, later London Transport Executive, was formed and ran under the name "London Transport".
On 7 November 1965, the first 30 Leyland Atlantean buses entered service on route 24. It was the first route to use front-entrance double-decker buses in London. Routes 67 and 271 also trialled front-entrance buses. On 12 June 1966, the Atlanteans moved to Tottenham garage and were replaced by AEC Routemasters. The route was crew operated until 25 October 1986, apart from two short periods in 1965/1966 and 1975.
The route was the first central London route to be awarded under the tendering process to a private company, Grey-Green, on 5 November 1988, using Alexander bodied Volvo Citybuses painted in its own grey, green and orange livery from its Stamford Hill garage. Grey-Green were owned by Cowie Group, and became part of Arriva London following the company's acquisition of two other London operators.
Upon being re-tendered, in November 2002 the route passed to Metroline's Holloway garage, and in 2006 was the first London bus route to be operated by Alexander Dennis Enviro400s. Upon re-tendering, on 10 November 2007 it passed to London General's Stockwell garage. Alexander Dennis Enviro400H hybrids were introduced to the route in early 2009.
On 11 February 2008, a bus on diversion had its roof removed after the driver drove into the side rather than under the middle of an arch bridge. Transport for London said the diversion was safe if drivers followed instructions, and had been operating successfully for over 24 hours. This came three months after another 24 lost its roof in the same place while out of service.
A night element to the route was introduced on 27 November 1999, in the form of route N24, to replace part of the withdrawn route N2 between Hampstead Heath and Pimlico. The N prefix was dropped during April 2004, thus making it a 24-hour route.
In February 2010 it was reported that a Muslim bus driver, new to the country, pulled his 24 bus over near Gospel Oak, locked the passengers in and prayed to Mecca. The Sun newspaper had to pay out £30,000 after allegedly misrepresenting the incidents stating that the driver was a fanatic who had forced passengers off the bus.
New Routemasters were introduced on 22 June 2013. The rear platform remained open from Monday to Friday between 05:15 and 19:50 when it was staffed by a customer assistant. In 2016, Customer Service Assistants were removed from Route 24.
