NEW YORK--(BUSINESS WIRE)--Dec. 22, 2008--WNS (Holdings) Limited (NYSE: WNS) a leading provider of global business process outsourcing (BPO) services, today announced a three year contract renewal with Centrica, extending an outsourcing relationship that began in 2005, with the potential to extend another two years in annual increments upon completion of the initial renewal term. Under the contract, WNS will continue to provide offshore customer service and billing support for Centrica's subsidiaries - British Gas in the UK and Direct Energy in the United States and Canada. In addition, WNS will continue to provide finance and accounting services and support to Centrica for both their UK and US businesses. Under the terms of the renewal, the companies together will also implement a transformational three year plan to further streamline Centrica's operations.

Centrica first partnered with WNS in 2005 when British Gas began rolling out a new customer billing system to provide customer assistance to support its businesses in the UK. In 2006, Centrica extended its scope of services to include UK finance and accounting, which received an "honorable mention" in the 2008 FAO Research Awards of Distinction. Subsequently, the company expanded WNS' scope to include finance and accounting and contact center services for Direct Energy in North America.

"WNS provides us a blend of functional expertise and process capabilities which spans across our diverse portfolio. Our partnership with WNS has become an integral part of our operations and we look forward to maintaining this stability and competitive advantage in a volatile energy market," said Phil Bentley, Managing Director - British Gas.

"We have seen measurable benefits from the start of our relationship with WNS, including lower cost of operations and increased process efficiencies while maintaining the quality of services we provide our customers," said Matthew Bateman, Managing Director of Pay As You Go Energy - Centrica's prepaid customer division. "The three year improvement roadmap that we have developed together will be central to obtaining additional operational efficiencies."
