Route 328 commenced operating on 29 May 1999 between Golders Green station and Chelsea via West Hampstead, Kilburn, Maida Hill, Notting Hill Gate, Kensington High Street and Earl's Court. It was initially operated by First London's Westbourne Park garage with Marshall Capital bodied Dennis Darts. It replaced parts of routes 28 and 31.
Early enthusiasm for hybrid vehicle technology, in which all or part of the motive power is provided by electricity rather than directly by the engine, saw a number of small batches of experimental vehicles ordered. One of the routes selected for trials was route 328.
When next re-tendered, the route was retained by First London with a new contract commencing on 30 April 2011. In October 2011, it moved from Westbourne Park to Atlas Road garage while the former was partially closed to make way for Elizabeth line construction works.
On 22 June 2013, route 328 was included in the sale of First London's Atlas Road garage to Tower Transit. With the closure of Atlas Road garage, route 328 returned to Westbourne Park in June 2017.
