Give it a couple of weeks, maybe ask your IP in the meantime ( if he hasn't done it, it will remind him or her ). Then do a search at HM Land Registry.

You can contact the Land Registry and also your IP although it may be a short while before it comes off if you have only just received your completion letter.
