The appeal process changed on the 19th December 2011 see this link http://www.ukba.homeoffice.gov.uk/si...67-appeal-fees

Applicants who appeal decisions dated 19 December 2011 or later from outside the UK will be required to submit their appeals directly to the First-tier Tribunal (Immigration and Asylum Chamber) in Leicester and will no longer be able to send them to the visa application centre overseas that made the initial decision. For more information about this process please see the Ministry of Justice website.

The appeal can be done in person or by post.
