How do I check if I'm overpaying council tax?

Enter your postcode into the Council Tax Checker tool to see your current council tax band and compare it with your neighbours. If similar properties nearby are in a lower band, you may be overpaying. The tool uses official Valuation Office Agency (VOA) data and is completely free to use.

How many UK homes are in the wrong council tax band?

According to industry estimates, over 600,000 properties in England and Wales may be in the wrong council tax band. Council tax bands are still based on 1991 property valuations, and many homes have never been reassessed despite significant changes in relative property values.

Can I get a council tax refund if I'm in the wrong band?

Yes. If you successfully challenge your council tax band and it is reduced, your council must refund the difference for the entire period you were overcharged. Refunds can go back to when you first moved into the property, which means some homeowners have received refunds of £2,000 to £5,000 or more.

Is it free to appeal my council tax band in 2026?

Yes, challenging your council tax band with the Valuation Office Agency (VOA) is completely free. You submit a challenge online at gov.uk. If the VOA rejects your challenge and you escalate to the Valuation Tribunal, that process is also free. You only pay if you choose to use a private claims management company.

Can my council tax band go up if I appeal?

It is technically possible but extremely rare. In 2016-17, the VOA moved 10,120 properties to a lower band and only 30 to a higher band. The key is to check your neighbours' bands first using the Council Tax Checker — if comparable homes are in the same band as you, an appeal is unlikely to succeed. Only challenge when you have clear evidence of misbanding.

Why are council tax bands still based on 1991 property values?

Council tax bands in England are based on what your property would have been worth on 1 April 1991. No government has carried out a revaluation since the system was introduced in 1993, because a full revaluation would create winners and losers and is considered politically risky. Scotland revalued in 2003, but England and Wales have not. This means bands are over 30 years out of date.

How long does a council tax appeal take?

The VOA aims to respond to band challenges within 2 to 3 months. If you accept their decision, the process ends there. If you disagree and escalate to the Valuation Tribunal, the full process typically takes 6 to 12 months from initial challenge to final decision. During this time you continue paying at your current band.
