How are council tax bands set?
Council tax bands are calculated using the value of the property you live in as it would have been at a certain point in time.
Then, based on the value, the property is placed into a council tax band - each band is charged a different amount of council tax.
The system for this varies in England, Wales, Scotland and Northern Ireland.
Properties in England are split into eight bands (A-H), depending on the price they would have sold for in April 1991, when valuations for the current system were made.
Scottish properties are split into the same number of bands, also based on their value in April 1991, but the band ranges are different.
Properties in Wales were re-valued in 2003, so property values are based on their market value on 1 April 2003. There are nine valuation bands, labelled A-I.
Northern Ireland is different once again, instead charging domestic rates. These are calculated by multiplying the rateable capital value of a property by the 'domestic rate poundage' - which is the sum of the domestic regional rate and domestic district rate.

Changing your council tax band
If you think your property has been put into the wrong council tax band, you can apply to get this changed.
This can be done by contacting the Valuation Office Agency (VOA) for England and Wales.
You can appeal to get your property revalued - if there have been changes to your property since the last valuation - such as being converted into flats.
If you think the original valuation on your property was incorrect, you can challenge this, too. You should check the 1991 value of your home and similar properties in your area before contacting your local valuation office and explaining why you think your banding is wrong.
Be aware that asking for a revaluation could result in moving up a council tax band, which could increase the amount you have to pay.
