How to pay Fee difference

Dear All Members

I need your help on getting the answer for following :

I paid my in-person appointment fee a month ago and now the fee is increased by about £69. I tried calling UKBA but they are only taking calls for Citizenship questions. I tried checking it online (the UKBA website from where I got the appointment) but there is no details about this. I believe that I need to fill my card details in the Set(O) form and the difference of the fee can be taken on the day of appointment ? If not, please advise what to do ?

Thanks in advance,
Praves

This question has been answered many times in the forum. Did you try searching for it?

I am sure I read somewhere that you don' t have pay any difference as you already booked your appointment.

i booked on 27th march for 7th April, charged old fee online, never asked to pay anything extra on the day, although I expected to have to pay. so yeah i reckon the fee is fixed the moment you pay it.
