[11][12] The units entered passenger service from 1 December 1992 with a ceremony at Cannon Street station, by Transport Secretary John MacGregor.

[10] They have mostly used on suburban routes out of London Victoria, Charing Cross, Blackfriars, and Cannon Street to destinations in South London and Kent, and the first 20 Class 465/0s were repainted into the Connex South Eastern Yellow and Blue livery in 1998, the same livery as seen on the 16 Class 365s introduced in June 1997.

[14] Some are scheduled to be replaced by Class 707s,[15] with two hauled to Worksop for store by Harry Needle Railroad Company in June 2021.

[16] Due to the size of the original order, British Rail approached two separate manufacturers to supply the new rolling stock.

[6] Plans were drawn up in 2007 to improve the reliability of the BREL and ABB units (Classes 465/0 and 465/1) by the installation of new traction equipment.

This included the installation of new wheelchair spaces and fully accessible toilets, more handrails, and tactile floor surfaces in the vestibule areas, and louder, more audible door alarms.
