Unilever has awarded an outsourcing contract extension worth €173 million (£144 million) to BT.

Under the contract, BT Global Services will supply services such as unified communications, messaging, supply chain and wireless technology to the household goods manufacturer in more than 100 countries over the next four years.

So far, BT has designed, manages and operates a fully integrated end-to-end IT networking infrastructure for Unilever’s global operations. The infrastructure currently delivers data, voice, video and mobility services to around 1,000 sites.

BT said that the new contract extension will enable it to help Unilever deliver its new supply chain applications.

CIO 100 ranked Unilever awarded the original €1 billion outsourcing contract to BT in November 2002.

Earlier this year, Unilever said that it had significantly improved efficiency and reduced complexity after completing a global rollout of a single SAP enterprise resource planning system.

Meanwhile, BT has recently managed to avert a strike by its staff after offering a pay deal to members of the Communication Workers Union, but is currently in proceedings at the High Court with the trustees of the BT Pension Scheme over the details of a Crown Guarantee.
