Following privatisation, the fleet passed into control of the West Anglia Great Northern (WAGN) franchise. At the same time, services were rebranded as the Stansted Skytrain. Units continued to be used on these services until 1997, when they became common-user with the rest of the WAGN fleet. After this, it was common for units to turn up on London King's Cross to Peterborough services. Four of the five units were subsequently hired to North Western Trains. However, on return to WAGN, they did not have any specific duties to work, as dedicated rebuilt Class 317/7 units were introduced to the Stansted Airport services in 2000. The Class 322 fleet therefore remained non-standard in WAGN's fleet, so in 2001 all five units were hired to ScotRail, who operated similar Class 320 units. The class was transferred north to Scotland in two batches under their own power, routed via the West Coast Main Line. National Express East Anglia, or One, operated a set from 2004. In late 2005 the set was transferred to First ScotRail. In the period 1997 to 1999, North Western Trains (NWT) hired four units from WAGN for a new Manchester Airport to London Euston service. These services did not last long, and by 1999 the units had returned to WAGN. From 2001 the units – having been made redundant on WAGN services – were used by First ScotRail, operating on the North Berwick Branch Line, between / and North Berwick. They were transferred north to Scotland and were put to work allowing the elderly incumbent Class 305 slam-door units to be withdrawn. One morning and one evening peak service were provided to Glasgow Central via the relatively quiet Edinburgh–Carstairs branch of the WCML to allow the units to receive maintenance at Glasgow Shields depot as First ScotRail's facilities in Edinburgh (at Haymarket and Slateford depots) are for diesel traction only. The units continued to be used on these services until mid-2004, when the hire period ended. They were transferred south in two batches, and were replaced on the North Berwick branch by EWS Class 90 electric locomotives hauling former Virgin Trains Mk.3 coaching stock. To enable trains to reverse the locomotive operated in push-pull mode with a Driving Van Trailer. In mid- to late-2005 the units were transferred back to Scotland for refurbishment prior to reintroduction on the North Berwick line, which was expected to be their permanent use.
