Only 5% of people are happy to have their bank account serviced by an overseas call centre, says a survey.
The relocation of call centres abroad has raised concerns
About 87% of people questioned said they would not be happy speaking about their account to someone abroad, while 9% said they had no preference.
The main concern about call centres going abroad was the threat to British jobs (82%), followed by fears about language difficulties (78%).
The poll of 2,421 people was conducted by YouGov for Alliance and Leicester.
Older people were more concerned than young people about the trend and women were less happy than men.
Just 2% of women said they would be happy to speak to someone in an overseas
call centre, compared with 7% of men.
Statistics published on Friday suggests the number of staff in British call centres is set to grow, despite the trend for relocating overseas.
Datamonitor said the industry in the UK has reached 435,000 and will increase to almost 500,000 over the next four years.
The Communication Workers Union warned last year that up to 200,000 jobs in
UK call centres could be "shipped abroad" over the next five to 10 years.
