Gas and electricity supplier EDF Energy is to outsource much of its IT support to Capgemini in a contract worth up to £100m.

The contract is initially for three years and EDF Energy has the option to extend it by a further two years. If the full term of the contract is seen out, EDF Energy will have invested £100m by the end of 2015.

The main objective of the outsourcing deal is to improve the quality of IT support services for EDF Energy’s UK business, making them more consistent and standardised.

As part of the contract, Capgemini will provide IT service desk support and managed desktop services – including email, instant messaging and file sharing – for EDF Energy’s 15,000 IT users.

Capgemini will also assist EDF Energy with its technology procurement.

The outsourcing arrangement will result in some of EDF Energy’s IT staff - as well as some staff from its current IT suppliers - moving to Capgemini, most of whom will be based in the UK.
