BA 2 for 1 voucher cancellation

[cyclistdave]

Hi
I need to cancel a flight booked for April on a BA 2 for 1 voucher. I’m aware that the voucher and airmiles used for the booking will be returned to my account, but what about the taxes and surcharges ( £900) paid at time of booking on my BA credit card.I can find no information on this in looking through BAs t and c’s.
Can anyone provide some insight on this. Will they be refunded to my credit card and if so in what time scale?
Thank you!

Yes. They should come back quickly i.e. in a day or two unless BA mess up which they sometimes do.

BA will deduct £35 per person which is the cancellation fee.
