Eligibility requirement
You must have been paying council tax for at least 6 months to request a band review. The VOA also considers property age and architectural style—properties of significantly different ages or styles may not be considered comparable.
An informal band review is free and cannot result in your band going up.

Council tax bands were set in 1993 based on estimated 1991 property values and haven't been reassessed since. If yours is wrong, your council must refund the overpayment.

Not through an informal review, which is what we recommend. Only a formal proposal (which you'd have to initiate yourself) can result in a band change — and even then, only 0.08% of formal proposals lead to an increase. That's 8 in 10,000.
Direct from the Valuation Office Agency (VOA) — the government body responsible for council tax banding in England and Wales. It's the same data you'd find on GOV.UK.
No. The free check just needs a postcode — nothing else. If you decide to buy the full report later, we'll ask for an email to send it to, but the check itself is completely free and anonymous.
Everything you need to challenge your band: an AI-written challenge letter personalized to your property, a professional evidence pack with maps and comparable data, plus complete submission instructions with VOA contact details. It's all ready to send — just email it to the VOA at ctinbox@voa.gov.uk or use their online portal.
Council tax bands were set in 1993 based on what the VOA thought your home was worth in 1991. They were done in bulk across 24 million properties and mistakes were inevitable — identical houses on the same street ended up in different bands. Bands haven't been reassessed since, so the errors have persisted for over 30 years.
CouncilTaxHero was built by Isaac Langley, a software developer who discovered that his own council tax band was wrong — and that millions of other homes probably are too. This tool exists because checking should be free and easy, not something you need to pay a consultant hundreds of pounds for.
