Thanks very much conmankiller - my local council's website is nowhere near as helpful (can't find anything relevant) but this at least gives an indication. Surely they must have realised I was earning though? What a mess. My parents have another visit next week - perhaps I'll try and be here.
Along the same lines, but as you know about this subject, how would I go about paying my council tax once I move out, the standing order & direct debit forms on the website for my area don't have spaces to reference an address, will they know once I move out or do I notify them? I don't want to get caught out! Think I've got quite a bit of sorting out to do...
