On 25 April 2014, the Vehicle and Operator Services Agency formally increased London General's licence to accommodate the Metrobus buses.

[12] In March 2012, the FirstGroup sold Northumberland Park garage, together with its 13 Transport for London route contracts, fleet of 130 buses vehicles and around 400 staff members, to the Go-Ahead Group for £12 million, with the garage's operations integrated into London General.

The Beddington Lane depot was opened by Metrobus in December 2005 to house route 127 which had been surrendered early by Centra.

Formerly the site of Oak Farm, which was purchased, built upon and used as the base of the independent Orpington and District bus company until its collapse in February 1981,[13] Orpington depot (also known as Green Street Green) was for many years the only garage for all of Metrobus' London tendered routes since the award of route 61 in 1986.

No injuries were reported and Orpington garage maintained a full service on the morning of 22 November, with numerous buses saved by being driven out onto Farnborough Way and surrounding roads.

Stockwell garage opened in 1952 as part of London Transport's tram replacement programme after nearly four years of planning and building, with many construction materials short of supply in the aftermath of World War II and problems rehousing residents of the houses that stood on the site.

Stockwell garage is a Grade II listed building, and when built was a masterpiece of architectural design incorporating a new roof structure that did not need supports which enabled for a 73,350-square-foot (6,814 m2) unobstructed parking space.

[17][18] In the first few days of operation, Stockwell garage ran just 11 buses on route 178 which had moved from Rye Lane (Peckham), but then gained more work from the next stage of the tram replacement programme for which it had been designed, but it was still well short of capacity.

[18] Between spring 1984 and August 1986, Stockwell operated a varied fleet of double-decker buses on route 170 as part of London Transport's Alternative Vehicle Evaluation comparative trial, aimed at finding a new standard double-decker bus type.

The vehicles trialled included a pair of MCW Metrobus Mk2s, one of which was built with a Maxwell transmission while the other had a Cummins L10 transmission, three ECW-bodied Leyland Olympians, three Northern Counties-bodied Dennis Dominators and three Alexander-bodied Volvo Ailsas,[19][20] the latter being the first front-engined buses delivered to London Transport since the last Routemasters were delivered in 1968.

The trial ultimately concluded in favour of the ECW-bodied Leyland Olympian, with London Transport taking delivery of a further 260 between 1986 and 1987.

Opened by the London General Omnibus Company in January 1924 at cost of £30,000, Sutton garage had a capacity for 100 buses.

The garage passed to the reborn London General bus company in the run-up to privatisation in 1985.

Sutton Garage also partly took control of route 200 at a yard in Colliers Wood (AA) in 1989, after Cityrama withdrew from their contract.

Sutton was responsible for providing drivers for the service, whilst Merton garage were contracted to do the maintenance.

In June 2002, the Red Arrow Leyland Nationals were replaced by London's first fleet of Mercedes-Benz Citaro articulated buses.

Because of the extra space required to stable these, the route 11 Routemasters were transferred to Stockwell garage.

London General previously had four[dubious – discuss] bus garages - Mandela Way (MW), Waterside Way (PL) and Belvedere (BV).
