Transport operator FirstGroup has signed a five-year contract worth £14m for desktop services with Computacenter.
The deal will include a central service desk, support and product supply for 5,500 users at 650 offices, railway stations and bus depots throughout the UK.
Glenn Bladon, group head of IT services at FirstGroup, said it awarded the contract to Computacenter as it demonstrated appropriate scale and expertise.
The contract is part of FirstGroup's new multi-sourcing approach to IT services and follows an announcement that it is looking for IT suppliers to support the delivery of its ERP system.
Computacenter recently said its business strategy included competing for services contacts within large multi-sourced deals.
