Almost 1,000 jobs are to be created in Britain after Powergen said all customer calls would be answered here rather than in India.
The country's second biggest energy supplier said it was pulling out of the sub-continent to create 980 jobs in the UK by the end of the year.
Around 450 of the jobs will be attributed to the ending of its operations in Delhi, while the remainder are new jobs which will be created.
The move followed a number of complaints from customers, as well as a decision that it would be easier to manage and train staff in the UK. Powergen, which has its national HQ at Coventry and employs 3,500 in the Midlands, started using Indian call centres almost five years ago, but will from now on answer all calls at the
company. Nick Horler, managing director of Powergen, said: "Offshore call centres may have their place for certain industries. We believe that we can best achieve industry-leading customer service by operating solely in the UK.
"When customers contact us they need to be confident that their query will be fully resolved quickly.
"Although the cost of overseas outsourcing can be low, we're simply not prepared to achieve savings at the risk or expense of customer satisfaction."
The starting salary for new British-based call centre staff will be raised.
