[5] In 2017, Stagecoach launched six new Alexander Dennis Enviro400 MMC buses for the route 64 to Alton, which also received extra journeys in evenings and Sundays, the unveiling taking place at the Winchester Science Centre.

[10] The company operates a number of routes across Hampshire and Surrey, serving Aldershot, Camberley, Farnborough, Godalming, and Guildford.

In 2002, a number 22 Stagecoach bus, operating a journey from Aldershot to the Old Dean estate, was hijacked by two armed men.

In January 2019, working with the BYD/ADL Partnership, energy storage specialist Zenobe Energy, as well as members of Surrey County Council and Guildford Borough Council, Stagecoach in Hants & Surrey introduced nine electric Alexander Dennis Enviro200EV buses on their Guildford Park & Ride network, representing an investment of over £3 million.

[23][24] However, shortly after the network expansion, Stagecoach reduced frequencies on its services owing to a driver shortage following the COVID-19 pandemic.

In August 1989, Stagecoach purchased Southdown Motor Services,[36][37] which had previously been owned by the National Bus Company until sold in a management buy out.

[38] In partnership with West Sussex County Council and gaining funding from the Government's Bus Back Better strategy, Stagecoach introduced a new route, numbered 500, from 2 July 2023 between Chichester and Littlehampton via St Richard's Hospital, Barnham and Yapton.

In September 2023, Stagecoach won contracts for 5 routes in Portsmouth previously run by First Hampshire & Dorset.

Fleet Buzz, initially known as Countywide Travel,[44] was formed in 1995 as a bus and coach company, based on vehicles from Marchwood Motorways and a depot was established in Basingstoke.

[45] Countywide Travel also parked buses at Hart District Council's Household Waste Recycling Centre near Hartley Wintney, but, due to safety concerns, vacated the latter premises in 2007.

Alongside the new Optare buses, four Plaxton Pointers and three Alexander ALX200s - one in plain white - were transferred from Selkent.
