London Buses route 427 is a Transport for London contracted bus route in London, England. Running between Uxbridge and Acton, it is operated by Abellio London.


Route 427 commenced operation on 9 April 2005 operating between Acton Market Place and Uxbridge Station via Ealing - Hanwell - Southall - Hayes End - Hillingdon Hill. The route was initially operated by First London from their Acton (AT) garage using Plaxton President bodied Dennis Tridents. The route was introduced in order to replace the withdrawn section of route 207 between Hayes By Pass and Uxbridge. Transport for London were proposing to build the West London Tram between Shepherd's Bush and Uxbridge, running along Uxbridge Road. The tram would have replaced the current routes 207, 427 and 607. Transport for London claimed that trams would carry more passengers and be more reliable, but due to the Crossrail project going ahead the plans were scrapped.

On 10 April 2010, the route was retained by First London with brand new Wright Eclipse Gemini 2 bodied Volvo B9TLs introduced.

On 21 February 2011, the route was extended from Acton Horn Lane to Acton Town Hall.

On 22 June 2013, the route was included in the sale of First London's Hayes garage (HS) to Metroline.

On 8 April 2017, the route passed to Abellio London operating from their Hayes (WS) garage using brand new Enviro 400 MMC bodied Alexander Dennis E40Hs and Alexander Dennis Enviro 400Hs. The route was extended in Uxbridge to start and finish in York Road at the same time.

On 29 April 2017, the route was converted to full Enviro 400 MMC bodied Alexander Dennis E40H operation.

The route will be withdrawn between Southall Town Hall and Acton Old Town Hall and diverted to Southall, Merrick Road to coincide with the opening of the western section of the Elizabeth line from December 2019.
