London Buses route H22 is a Transport for London contracted bus route in London, England. Running between Hounslow and Richmond, it is operated by London United.
Route H22 was introduced on 28 April 1990, as a replacement for the western end of route 202. Running Monday to Saturday between Richmond (Lower Mortlake Road) and Hounslow West Station, with a Monday to Friday peak hours, and an early Saturday morning extension to Hatton Cross Station. The route was operated from Hounslow garage. The initial daytime frequency of every 20 mins, was a vast improvement over the 30-35 mins offered on the 202. The frequency has been improved a number of times since, and is now 12 mins during the daytime, and 20 mins evenings and Sundays
The section between Hounslow West and Hatton Cross did not last long, being withdrawn in 1992 with the introduction of an improved service on Routes 201 & 203.
A Sunday service was introduced for the first time in 1994.
The route was further cut back from Hounslow West to Bell Corner at the time of tendering in 1999.
The Richmond termini changed from the Dee Road stand (off Lower Mortlake Road) to Manor Circus in 2002.
Over the years the allocation has swapped between Hounslow (AV) and Hounslow Heath (HH). It has been at Hounslow Heath since 12 November 2005.
On 6 March 2004, the route was retained by London United.
On 3 March 2011, the route was retained by London United.
The route will be retained by London United from 3 March 2018.
Initially the route was operated by Carlyle bodied Dennis Darts, under the brand name Harrier. From 1991 Plaxton Pointer bodied Dennis Dart's supplemented the Carlyle version at Hounslow and eventually replaced them.
In 1999, it was retained by London United and was converted low floor operation using brand new 10.8m Plaxton Pointer 2 bodied Dennis Dart SLFs introduced.
On 12 November 2005, these were replaced by shorter 10.2m vehicles, made surplus when London United lost route 33 to NCP Chalanger.
In November 2010, the DPS's were replace with DPS's, again displaced from route 33.
In the 1990s double deckers made occasional appearances on the route, but in more recent times, it has been solidly single deck, mainly Dennis Darts, but the odd Alexander Dennis Enviro200 Dart from the London Bus Route 285 has been used.
The Plaxton Pointer 2 bodied Dennis Dart SLFs will be replaced by Alexander Dennis Enviro 200 Darts and Enviro 200 MMC bodied Alexander Dennis E20Ds.
