He's become an international superstar whose fans include George W Bush and the Queen.
But would you buy insurance off Ozzy Osborne? Well according to a new survey the answer is no and not just because he has a penchant for bats.
It is all to do with the accent and it seems that along with those from Liverpool and Manchester, the Brummie accent is the least trustworthy when s peaking to financial workers over the phone.
However, with 50,000 jobs set to be created in the sector in Birmingham over t he coming years, a spokesman for the Birm ingham Chamber of Commerce said the results of the survey should be treated with a large pinch of salt.
He said: "Birmingham is the second biggest financial service sector outside London and would not be growing if the accent was so unpopular."
Richard Brennan, chief executive of Birmingham Forward, said he had never heard of any complaints towards the Birmingham accent.
He stressed the importance of trust in financial services particularly in the legal and banking sectors and believes that the
Brummie accent was actually an advantage to businesses.
"A distinctive accent like the Birmingham accent is often well remembered," he said.
Alison Hadley, a team manager at Wesleyan's contact centre in Birmingham, also said she had not received any comments of dissatisfaction from customers towards the Birmingham accent.
She added that a call monitoring system was in place to check how staff sound over the phone, to check they are understood without the use of slang or difficult jargon.
"Customers are much more interested in the quality of the service than what accent they hear," she said.
The Scottish accent topped the table as being the most trustworthy, closely followed by London and the South-East.
