You need to check your registered title, it's probably with your deeds (if you've got them) or you may have been given a copy at the time of purchase from your conveyancer. If not, you can order a copy from Land registry for 3 quid or so. The council will be able to check their ownership if you give them a call. If it's DCC I can take a look for you.
