Around 400,000 UK homes are in the wrong council tax band — and refunds can be backdated all the way to April 1993, sometimes worth £5,000+ in lump sum.
Council tax bands in England and Scotland are still based on what your home was worth in April 1991. In Wales, it’s April 2003. The original valuations were rushed “drive-by” assessments that got tens of thousands wrong. Use the checker below to see if you might be in the wrong band.

Northern Ireland uses a different “rates” system, not council tax bands.
Check your council tax bill or look it up free at gov.uk/council-tax-bands.
Use the Nationwide House Price Calculator (free) — enter what you bought it for and the date, then set the valuation date to Q2 1991. For Wales, set it to Q1 2003.
Refunds backdate to when you moved in (or April 1993, whichever is later).
This is a guide based on official 1991 (England/Scotland) and 2003 (Wales) banding thresholds. Your actual band is set by the Valuation Office Agency (VOA) in England/Wales or Scottish Assessors in Scotland. Challenging your band can sometimes result in your band being increased rather than decreased — read the warning carefully before submitting a challenge. We are not a regulated tax adviser.

Why might my Council Tax band be wrong?
Council Tax bands were set in 1991 based on quick estimates. Hundreds of thousands of UK homes are believed to be in the wrong band, often higher than they should be.
How do I check my Council Tax band?
Compare your band with your neighbours on the official VOA website. If yours is higher than identical homes nearby, you have grounds for a challenge.
What happens if my band is reduced?
You get a refund backdated to when you moved into the property (potentially decades) and your future bills drop permanently to the lower band amount.
