How it works
From postcode to appeal pack in three steps.
We've automated the manual neighbours-check that successful challengers do themselves — and packaged it as evidence the VOA expects.
Compare your band
We benchmark your property against every comparable home on your street.
Enter your postcode and we'll instantly query the official Valuation Office Agency dataset. We pull every council tax band on your street and in surrounding postcodes, filter for properties of similar type, size, and age, and show you how yours compares using the same 1991 valuation benchmarks the VOA used.
Build your appeal pack
An evidence-led pack the Valuation Tribunal expects to see.
If your band looks higher than comparable neighbours, we generate a complete appeal pack: a detailed comparison report listing every relevant property in your area, plus a draft challenge letter that follows VOA and Valuation Tribunal procedures word-for-word. Everything you need to make your case in one downloadable PDF.
Submit and save
Submit free to the VOA. If successful, your band drops permanently.
You submit your pack to the VOA via their free online form — no solicitor required, no fees from us at submission, and no risk beyond the rare possibility of an upward reband (which is why we show you the evidence first). If successful, your band is permanently reduced and you may receive a refund covering years of overpayment.
