We've done some research into just how many people have been affected by bank charges - and the findings suggest that many so-called 'free' bank accounts can actually work out quite expensive.
42% of current account holders have been charged by their bank in the past. 57% of those - around 11 million people - have been pushed into an unauthorised overdraft as a result, meaning they incur further expensive charges.
The average amount paid in charges over the last 12 months comes to just under £50, but a third of those charged have paid more than £50, and one in six have paid more than £100 in the last year alone.
The findings will add further fuel to the debate over whether 'free banking' truly is free. Our research indicates that in many cases, it most definitely isn't.
Do you know how much you've been charged?
Worryingly, 5% of people with a current account - around 2.3 million people - actually don't know whether they've been charged or not. A further 3% know they have been charged, but don't know how much.
Most common bank charges:
|Charge||Paid by % of account holders|
|Unauthorised overdraft fees||20% (9,394,172 people)|
|Unauthorised overdraft daily charges||15% (7,045,629 people)|
|Overdraft warning letters from bank||14% (6,575,920 people)|
|Bounced direct debits||13% (6,106,212 people)|
|Unpaid standing orders||8% (3,757,669 people)|
|Other penalty charges||7% (3,287,960 people)|
|Bounced cheques||6% (2,818,252 people)|
