As part of the privatisation of London bus services, Metroline was sold in October 1994 to a management buyout worth £20 million (equivalent to £50,246,000 in 2023).

[2] Metroline later purchased MTL London in July 1998,[3] and in February 2000, was eventually sold to ComfortDelGro for £73.8 million (equivalent to £156,899,000 in 2023).

[7] In June 2013, Metroline purchased First London's Alperton, Greenford, Hayes, Uxbridge and Willesden Junction garages with 494 buses.

In 2014, a blue, white and red commercial livery was introduced on buses dedicated to non-Transport for London services.

London's first night bus service, route 94 between The Crown pub in Cricklewood and Liverpool Street Station, was first operated from the garage on 15 July 1913, running at a frequency of every 20 minutes from 12:40 am until 9:00 am.

[14] In 2007, bus parking was temporarily relocated to a site on the opposite side of Edgware Road to allow work to start on the replacement of the original buildings with a modern structure.

When Edgware garage was first opened by the London General Omnibus Company in 1925 it had space for 24 buses, but there was plenty of room adjacent to the then recently built underground station.

In 1939 a new building was erected next to the original one, which was to become the new bus station, while the remaining open parking area was used to store vehicles for the trolleybus replacement programme.

In its earlier years the garage was used by experimental vehicles including the Daimler CH6s and the first diesel bus (ST).

30 new MCW Metrobuses, the only new buses for the operator among a handful of second-hand purchases, were leased to the company upon its launch.

Perivale is home to Metroline's fleet of Wright StreetDeck Hydroliner FCEV double-decker buses, the first of the type to operate in England.

This time it was saved after workers accepted a revised pay agreement and the depot tendered for and won Hertfordshire County Council commercial routes.

This role was revived in World War II when Willesden was also used to provide major body overhauls for London Transport.

[27] Willesden was London's first bus garage to operate battery electric double-decker buses, taking delivery of five BYD K8SRs in March 2016 for trial use on route 98.

[28] After having trialled a system involving audio-visual alarms and reflective tape on the route in early 2018 as part of Transport for London's Bus Safety Innovation Challenge,[27] 24 buses on Willesden's route 98 received "Vehicle Avoidance Lateral Lights" (VALLs) during 2018 as part of Transport for London's Bus Safety Challenge, with audio-visual alarm systems and reflective tape installed in an attempt to reduce pedestrian injuries on Oxford Street.

Greenford bus garage is part of a Ealing London Borough Council depot and was first used in March 1993 as a midibus base.

The standard vehicles the garage in the late 1990s were Wright bodied Renault midibuses and Marshall minibuses, however both types had a bad reputation and did not last long in the CentreWest fleet.

From late 2003 until 14 March 2009, Ealing Community Transport operated route 195 from the Greenford depot, using garage code EY.

Buses allocated to the service are MCV EvoSeti bodied Volvo B5LHs branded in a red and white livery with a route map on each side of the bus.

The garage passed to Thames Valley a year later, eventually being handed back to London General on 31 December 1928.

The new garage, located next to Uxbridge tube station and occupying the lower ground floor of a multi-use development, opened in late 1983.

[35] After passing to the CentreWest subsidiary in 1989, Uxbridge garage began operating the U-Line network of local routes using 16 seater Alexander bodied Mercedes-Benz midibuses in an initiative by London Regional Transport.

[32] Uxbridge garage also operated the busy routes 207 and 607, the latter of which received a fleet of refurbished East Lancs Greenway bodied Leyland Nationals branded for the service in 1992.

[36] In 1994, the garage was allocated some of London's first low-floor buses, these being Wright Pathfinder bodied Dennis Lance SLFs with CentreWest branding for route 222.

Alperton garage was enlarged between 1976 and 1978, the extension of which encompassed an adjacent former Underground substation, as well as the site of London Transport's Lifts and Escalators department.
