Company history

Early history

Original London Sovereign logo

London Sovereign^[1] 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 Services was 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.^[2][3]

RATP Dev era

After London United was transferred to RATP Group as a result of the wider Transdev group's merger with Veolia Transport in March 2011, London Sovereign became Transdev's only London bus company. In March 2014, London Sovereign was sold to RATP and resumed trading as London Sovereign.^[4] In December 2021, RATP's London bus operations including London Sovereign were transferred to a RATP joint venture with Australia's Kelsian Group (parent company of Tower Transit) known as RATP Dev Transit London.^[5]

FirstGroup era

In February 2025, London Sovereign was included in the acquisition of RATP Dev Transit London by FirstGroup, becoming part of First Bus London.^[6]

Garages

London Sovereign operates three bus garages.

Edgware (BT)

AEC Routemaster on route 13 at Trafalgar Square

As of July 2025, Edgware garage operates routes 79, 125, 226, 288, 303, 326, 340, H11, H12 and N5.^[7]

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.^{[citation needed]}

Harrow (SO)

As of July 2025, Harrow garage operates routes 183, 395, 398, H9, H10, H14, H18, H19, SL9 and SL10.^[7]

Harrow garage opened in 1994. It is First Bus London's smallest London garage holding just 42 buses. The low roof beam across the middle of the depot building was raised to allow double deckers. The garage has a plot of land next to it, owned by London Sovereign, which is now used to park most of the single deckers due to the 183 allocation, which started on 24 July 2015. Route 183 is now fully allocated to Harrow, with routes 398 & H17 transferred to Park Royal (RP) to make room. As of 7 September 2019, route H13 has moved to Uxbridge garage, which is owned by Metroline. In 2020, London Sovereign started operating routes 398 and H17. In December 2021, RATP Dev started operating their first electric buses for routes H9 and H10. More electric buses were introduced into routes 183, 398 and X140 (now SL9).

Parr Road (CP)

As of November 2023, Parr Road garage operates routes 288, 303, H11 and H14. Buses are regularly shared with Edgware garage.^[8]

North Wembley (NW)

North Wembley garage operated routes H9 and H10.

On 26 January 2019, part of the allocations of routes H9 and H10 were temporarily transferred from Harrow (SO) garage to this garage.
