I had to give up with this one, more effort than it was worth. It could have been worthwhile but the folks at Natwest kept giving me the run-around so I felt someone else can have my business.
Initially I applied and they called me back whereby they asked how I would be funding the account. I'd specified that being a company director I'd only be paying in occasional dividends rather than a monthly salary which they said was fine. However they then wanted copies of payslips. When I called and they couldn't help they said they'd call me back - they never did.
Pretty awful service really.
