Received approval letters today along with ceremony invitation letters. Despite informing UKBA of change of address, letters were posted to old address and thankful to redirection services, got them delivered to the new address. However,

1. Do I need to inform local council of new address before the ceremony?
2. Is there an address on the citizenship certificate?
3. The proof of ID required on the ceremony, if it has different address, will it cause any problem?
4. Lastly and additionally, does the citizenship certificate has the title as well or only the full name? (As title is wrong on the invitation letter) Title can be changed for the passport??

Many thanks

1) Yes, I think that would be advisable for a number of reasons.
2) No, unless they changed it recently. Here is an example. This is an older example (but as you can see, essentially the same thing).
3) I don't think so, but send them a letter beforehand explaining the situation - apart from the fact that they may offer helpful advice, it will avoid confusion later.
4) I am not entirely sure - but according to the web it does, yes.

Thank you very much Gyfrinachgar.
