I have some examples of the old and the new costs, from my letter. I have an Arranged Overdraft. There was formerly a £6 charge for any month that an overdraft was used. Now there is just an interest charge.
Example: cost of arranged overdraft £500 - 7 days old £7.75, new £3.24
Example: cost of arranged overdraft £500 - 30 days old £13.51, new £13.87
Example: cost of arranged overdraft £500 - 60 days old £27.23, new £28.12
