The origins of Ipswich Buses can be traced to November 1903 when Ipswich Corporation commenced operating trams. In 1923 the trams were replaced by trolleybuses. Buses were introduced from August 1950. To comply with the Transport Act 1985, in 1986 the assets of Ipswich Corporation were transferred to a new legal entity, Ipswich Buses.[1]
In February 2016, a deal was finalised to take over the staff, bus routes and most vehicles of independent operator Carter's Coach Services.[3]
