The vintage buses are seen at bus rallies, on television advertisements and on special days usually around Christmas on their H1 route.
Imperial Bus Company, purchased Travel with Hunny during September 2007, however the two companies divided again in January 2008. Both companies are now separate, and are in no way connected.
In September 2010, Imperial introduced commercial route 339 between Blackmore and Warley via Ongar and Brentwood, operating every hour on Mondays to Fridays in competition with Arriva Shires & Essexroute 501. This is Imperial's first commercial operation since the H1 was withdrawn. Due to low patronage, the 339 was withdrawn on 13 December 2010.
From 4 April 2011, Imperial started operating Thurrock Council contract route 11, from Purfleet Station to Chadwell St Mary via Aveley and Orsett. Previously, the route had operated from Purfleet to Basildon and was operated by Clintona Minicoaches, and before that it was operated by Blue Triangle.

Many routes, mostly Essex County Council contracts, were previously operated by Imperial Buses.
One of Imperial's first routes was the 100 which began on the 7th December 2000, operating between Loughton and Buckhurst Hill via Debden. The route started from Loughton Station, then through the High Road up to Homebase and Debden Estate, before serving Debden Broadway then operating along Oakwood Hill and Valley Hill/Loughton Way until its terminus at Buckhurst Hill Station. The route was apparently operated by Scania Metropolitan buses. The route only lasted a few months, and it is not known when it stopped operating.
From the 19th December 2009, route H1 was withdrawn. This was probably Imperial's most well known route, and has operated since September 2001 (when Arriva route 502 was withdrawn which operated between Romford and Harlow). Regal Busways new Saturday service H1 (Essex CC contract) and Travel with Hunny's route 55 replaced the route. The 55 has since been replaced by route 555, and the current Saturday service of the H1 is under consideration to be withdrawn.
