How to check and challenge your council tax band
Your council sets the amount you pay for each band, but the band itself is set by a separate government body. In England and Wales that's the Valuation Office Agency (VOA). If your home is in the wrong band, you could be paying too much every year. Here's how to check, and what to do if you think it's wrong.
How bands are worked out
Bands are not based on what your home is worth today. GOV.UK says bands are based on the price a property would have sold for on 1 April 1991 in England, and 1 April 2003 in Wales. In Scotland, bands are also based on 1991 values and are handled by local assessors; you check them on the Scottish Assessors Association website.
The VOA considers things like size, layout, character, location and any change in use. It doesn't use house price indexes to work out bands.
Step 1: check your band and your neighbours'
Use the GOV.UK: check your Council Tax band service (England and Wales). Search your postcode and look at homes similar to yours: same street, similar size, age and type. If several similar homes are in a lower band, that's worth looking into. One different band on its own may have a good reason, like an extension.
Step 2: decide which route applies
The VOA explains there are two types of challenge:
- Proposal (a formal challenge). You can usually make one if you've been paying council tax on the property for less than six months, if the VOA changed your band in the last six months, or if there's been a physical change in your local area. The VOA must review your band if you make a valid proposal.
- Band review. If you've paid for more than six months, you can ask for an informal review. The VOA isn't legally required to consider these and says it takes forward reviews where there's strong evidence the band is wrong.
Step 3: gather evidence
The VOA says evidence is usually up to five similar properties (sometimes called comparables) in a lower band. Note their addresses, bands, and why they're similar: number of bedrooms, type (terrace, semi, flat), age and size. Sale prices from around 1991 (or 2003 in Wales) can help if you have them.
Step 4: submit and wait
You can apply through the VOA's online service, by email or by letter. It's free. You don't need to pay a company to do this, although you can.
The risk: bands can go up
This is important. The VOA says challenges have three possible outcomes: your band can go down, stay the same, or go up. It may also review similar neighbouring homes. So only challenge if your evidence is strong, and be honest with yourself about any extensions or improvements.
If you disagree with the decision
GOV.UK says that if you disagree with the VOA's decision on a formal challenge, you can appeal to the Valuation Tribunal, normally within 3 months of the decision. Keep paying your council tax while a challenge is going on.
Check your discounts as well
Even if your band is right, you might be missing a discount. If you live alone, read how to get the 25% single person discount.
