BT has said it will create 500 jobs at four call centres in Wales and the north of England.
The roles will mainly be based at customer service centres in Swansea, Warrington, Doncaster and Accrington.
The jobs top a previously announced plan to recruit 1,000 people across the UK and Ireland by the end of March 2017.
Libby Barr, the managing director of customer care at BT Consumer, said on Monday: “We are proud to be creating these new jobs in the UK and Ireland. BT is completely changing the way we serve our customers in order to boost our service levels.
“We are going to answer 90% of our customers’ calls in the UK and Ireland by the end of March, and we have been taking on great people to fill full-time jobs working for BT.
“There are opportunities to earn £500 by referring a friend and also openings for agency advisers who want to work for BT directly.”
Last year, BT announced plans to increase the number of calls answered in the UK from 50% to 80%, after customers said they did not like speaking to staff in Indian call centres.
The company created 1,000 UK call centre jobs in 2015 and doubled the figure in January. It has 20 call centres across the UK.
The plan is part of an effort to improve BT’s standing in the table of customer complaints compiled by Ofcom.
