Council tax bands are set by the Valuation Office Agency (VOA). If you think your property is in the wrong council tax band, you can challenge it online at the GOV.UK (external website).
You'll need to tell them why you think your council tax band is wrong, for example, if similar houses in your street are in a different band.
There are companies offering to help people appeal against their banding in return for a fee. This isn’t illegal, but it's FREE to make an appeal and you can do it yourself.
The VOA will change your band if they agree it's wrong. We'll then send you a new council tax bill for the new amount. Until then, you must keep paying the amount shown on your bill.
To challenge a VOA decision, you can appeal to the Independent Valuation Tribunal (external website).
