145 Class 720 units were ordered in the five car configuration only; these are to be operated across multiple suburban lines leading out of both London Liverpool Street (Greater Anglia and c2c) and London Fenchurch Street (c2c). Originally intended to be introduced during 2019, delays were encountered during development that minorly impacted this timetable. On 26 November 2020, Greater Anglia commenced the Class 720's introduction. Its initial operations were centred on the London Liverpool Street to Southend Line. All Greater Anglia units were intended to be in service by the summer of 2020. c2c's fleet entered service on 27 September 2023.
