of Glamorgan services, Class 142s were often coupled together with Class 143 or Class 150 units to cope with demand on the busy Valley Lines network. The Class 142s received minor refurbishments with retrimmed seats in new moquette, plus the installation of ceiling-mounted CCTV cameras. South West England Twelve Class 142 Pacers were received by First Great Western in 2007, and started operations in December 2007. These were loaned from Northern (where they had been stored), in part to cover for the refurbishment of FGW's Sprinter fleets but also to allow the s to be reformed as three-coach sets. The 142s were based at Exeter TMD, working alongside the similar s on services in Devon and Cornwall, including the Avocet Line, Riviera Line and Tarka Line. Five 142s were returned to Northern Rail in the autumn of 2008, following the completion of the refresh of Class 150 Sprinter units. The remaining seven units were returned to Northern Rail in November 2011 after being replaced by class 150 units cascaded from London Overground and London Midland.

Wales & Borders franchise holder KeolisAmey Wales planned to replace all of its Class 142s by mid-2020. In August 2019, Arriva Rail North retired seven and placed them in store at Heaton TMD. Scrapping commenced in December 2019 with 142005 taken to CF Booth, Rotherham. In December 2019, three withdrawn Arriva Rail North units were transferred to Transport for Wales for spare parts. In December 2019, both Arriva Rail North and Transport for Wales were issued derogations to allow use into 2020. Northern Trains was permitted to operate the units until 31 May 2020, but only when coupled to a compliant unit, while Transport for Wales was
