Why is my next door neighbours Band different to mine?
If the properties are identical, they should be in the same Band, but if there are differences, for example one of them has an extension this could account for the difference. The ranges of values in the bands are quite wide and these are shown on the Council Tax Band page. If you believe the Band of your property is wrong you may appeal against it to the Listing officer at the Valuation Office. Information on making an appeal can be found on the Valuation Office Agency website.
