Three steps to find out if you are overpaying — and everything you need to challenge it.
No council tax number needed. Just your postcode and house number.
We run your property through all 5 factors instantly and return a 0–10 score with a breakdown of every signal found.
One payment. Instant access. Everything you need to challenge your band is generated and ready to download.
Your case strength score (0–10) is calculated from five independent data sources, each weighted by how strongly they predict a successful appeal.
We compare your band against every property in your postcode using official VOA data. If similar homes nearby are in a lower band, that is the strongest single indicator of misbanding.
Using 29M+ Energy Performance Certificates, we compare your floor area, room count, and construction age against neighbours. If a larger property nearby pays less, that is meaningful evidence.
Council tax bands are fixed to 1 April 1991 values. We use Land Registry price paid data and the ONS House Price Index to estimate what your property was worth then — and which band it implies.
We cross-reference your area against our database of Valuation Tribunal decisions. If similar properties have been successfully rebanded nearby, that is powerful precedent for your case.
Conservation area designations, listed building status, and post-1991 planning applications can all affect how your property compares to neighbours. We flag any relevant factors.

When you challenge your council tax band, the VOA can review it in either direction. In rare cases your band could go up. Our Case Risk Assessment section in every report gives you an honest assessment of this risk before you decide to proceed. The challenge process via gov.uk is free. This tool is not legal advice.
