Councils are struggling for money so using every loophole they can. I suppose you are lucky they don't try and surcharge you eg 150% as property is unoccupied. They are removing/reducing most discounts. I pay nearly £2,000 for a two bedroomed flat in Hampshire.
@cynical_al having to pay CT on an unoccupied property wouldn't make any difference to my thought process, I suppose that means its reasonable to charge it I do think that by removing the discounts the councils are encouraging fraud as youl'l see an increase in properties declared single person occupied.
@mudshark second homes used to get a discount (50%) as logic was they where not using services like education, hospitals, refuse collection and the owners where paying full ct elsewhere. However in current situation of councils needing revenue it's reasonable to charge full price.
