They were originally deployed on services from to via and via . On occasion, units were also operated to Paignton. While operated by FGW, the Class 180 suffered from numerous technical problems, including instances of the doors closing and locking quickly. These difficulties were persistent enough that the train operator decided to begin the early replacement of the Class 180 on the majority of its services, instead opting for considerably older HSTs that had been formerly operated by Midland Mainline before their replacement by Class 222s. FGW later re-leased five Class 180s for operating express commuter services from London Paddington to , Worcester, and . A combination of factors, not only the reliability problems experienced but also increasing passenger numbers, reportedly led to FGW deciding to acquire additional refurbished HST sets towards the end of 2007, which became the replacement for Class 180s on the express commuter services. Between 2007 and 2009, the majority of the fleet was returned to the leasing company Angel Trains.

A pair of the units operated in multiple on an early-morning Oxford to London commuter service, before being divided to work independently the rest of the day (after returning as empty stock to Oxford) on the Cotswold Line from Paddington to Worcester and Hereford. On 30 March 2009, the final Class 180 service in FGW's hands was operated. The remainder were placed in store from December 2007 at Oxley TRSMD. During 2009, five Class 180 units (102-104, 106 and 108) were leased by East Coast; they were intended to be operated on new services, however these were abandoned. Thus, all five were returned to FGW, where they were used to increase capacity on Thames Valley services, while three units were operated by Northern Rail in the interim. The Class 180s were introduced on the Cotswold Line, which released and Turbo DMUs for use on Thames Valley services. On 28 May 2012, the first refurbished Class 180 commenced passenger service.
