Just wanted to ask you about cost of ceremony. I was in the impression that cost of ceremony is included in the fees when you apply. Here is the text from their Web Site. Let me know if you are talking about someother fees or you are referring to the same fee that was included in the application time.

Naturalisation 6(2) - £268 (includes ceremony fee)
Naturalisation Joint 6(1) -£336 (includes two separate ceremony fees)
Adult Registration - £188 (includes ceremony fee)
Minor Registration(s) - £200 (Single/Multiple Applications)
Renunciation - £120
For further information please contact the Nationality Helpdesk on 0845 010 5200.
