Really stupid question-£0 credit card balance

[Ladydutchalot]

If your payment for the month is £0, do you still have to make a pretend payment as it were? Or just leave it? Online banking wants me to make a payment of £0.00, but won't let me IYSWIM, but have convinced myself they will put it down as a missed payment if I don't attempt to make a payment

Why don't you make a payment of £0.01?

If you have a zero balance on a credit card then how can you 'miss a payment'? If you don't owe them anything, don't pay anything.

No you don't have to make a payment.
