I have banked with Tesco for over 5 years now, with a saving account. I have a salary paid in every month by BACS, and if I want to transfer money to my main Co-op account, its easy to do in any Post Office. It is rare that I have any others money to put in, but if I do have a cheque or some cash, then the Customer Services counter at any Tesco seems to manage quite well enough. When I want to take money out, any cash point will do, not just Tesco.
Their on-line facility works very well, and the security is better than most.
I have no complaints whatsoever with this account, although I shall probably keep my main Current Account with the Co-op, who have swerved me well for 41 years !
