London Sovereign can trace its roots back to independent Borehamwood Travel Services which ran a fleet that included ex-Kelvin Central MCW Metrobuses and Northern Counties Palatines bodied Leyland Olympians and a collection of other vehicles. In 1993 it won its biggest London Buses contract, to operate route 13 with leased AEC Routemasters in its orange livery. In August 1994, Borehamwood Travel Serviceswas sold to the Blazefield Group's Sovereign subsidiary, with the two operations merged as Sovereign London. On 3 November 2002, the business was sold to Transdev, and renamed Transdev London Sovereign.
London Sovereign operate two bus garages.
Edgware garage was first opened by the London General Omnibus Company in 1925 with space for 24 buses, but there was plenty of room adjacent to the Underground station which had recently been built. In 1939 a new building was built next to the original building which was to become the new bus station, while the remaining open parking area was used to store vehicles for the trolleybus replacement program. In 1984 a new 100 bus garage was built on the site of the long closed Edgware railway station at a cost of £4.5 million. In 1992 plans were made to close Edgware garage as Cricklewood garage was to become a fully functioning garage with new facilities. The outdoor parking area and the bus station then became a midibus base in 1993, with a new bus wash and light maintenance facilities provided in the yard.
In 1999, London Sovereign, having won some tenders for bus services in North-East London, took a 10-year lease on half of Edgware garage and invested in a new maintenance facility which was to replace its former base at Borehamwood. In late 2000, Metroline moved back into the other half of the garage, making it one of the few garages to be shared by two operators.
On 3 September 2011, London Sovereign commenced operating route 251.
On 1 September 2012, London Sovereign commenced operating route 605.
