A number of residents have received a letter from a firm of solicitors offering to try to get them into a lower Council Tax band. Be very cautious. It is unlikely they can do anything you can’t do yourself for free. In fact, the circumstances in which you can get a lower banding are quite limited. These are explained on the Valuation Office Agency website: www.voa.gov.uk/corporate/index.html
They give a warning about Council Tax scams. From this website you can also check the Council Tax banding of your neighbours.
