Transport for London (TFL) has put out a tender for IT support for its 30,000 employees that will run for 10 years and cost up to £70m.

The tender - which was placed with the Official Journal of the European Union - requests a centralised service desk to provide a single point of contact for all IT-related incidents.

The successful supplier will take on some existing TFL IT staff under TUPE.

In addition to service desk responsibilities, TFL wants the supplier to provide user self-service tools, adherence to governance, service performance reporting based on agreed service levels, customer satisfaction surveying and reporting and continuous service improvement activities and suggestions.
