Go-Ahead London is the trading name used collectively for the London bus operations of the Go-Ahead Group. The name first appeared in August 2008, before which the company had traded under separate names and brands. It is the largest bus operator in London, operating a total of 115 bus routes under contract to Transport for London.
The Go-Ahead Group is a large transport group based in Newcastle. It first became involved in London bus operations in September 1994, where upon the privatisation of London Buses it purchased London Central. In May 1996, it added another former London Buses subsidiary, London General, which had been sold in 1994 to a management buy out. These two companies subsequently developed in much the same way, both establishing a livery of red with a charcoal skirt and yellow relief band, and splitting orders for new buses.
Further expansion did not occur until September 2006, when Docklands Buses was purchased. On 29 June 2007, the Go-Ahead purchased Blue Triangle. With these purchases, Go-Ahead surpassed Arriva London to become the largest operator of buses in London, running around 16% of London bus services.
A corporate image for Go-Ahead's London bus services started to appear in August 2008, when a new Go-Ahead London logo was unveiled.
In 2009, Transport for London invited bids for the sale of their own bus operations which ran under the East Thames Buses brand. Go-Ahead London were selected as the preferred bidder and assumed full responsibility for 10 routes and two depots in October 2009. The East Thames brand was replaced with the Go-Ahead London brand. The East Thames operations were initially absorbed under the London General arm of Go-Ahead's London business. However, after some route movements and allocation changes some of the services now run under the London Central.
On 30 March 2012, Go-Ahead purchased Northumberland Park Garage from First London with all routes brought under the London General wing.
In April 2014, Go-Ahead restructured its Metrobus business with the management of the Transport for London contracted services passing to the control of Go-Ahead London, with the remaining services administered by Brighton & Hove, still under the Metrobus brand. In June 2014 the London services were integrated into London General.
