How to Use This Calculator
Check My Band tab
Select your nation (England, Scotland, or Wales), then enter the estimated property value at the relevant valuation date — 1 April 1991 for England and Scotland, or 1 April 2003 for Wales. This is not today's market price; it is what the property would have been worth at that historical date. Select your current council tax band from your bill and indicate whether only one adult lives there (to apply the 25% single person discount). The calculator compares your estimated band against your current band and flags any mismatch.
What Could I Save? tab
Enter your current band and the band you believe you should be in. The calculator shows the annual saving using national average Band D rates for 2025/26 and the 10-year cumulative saving — the most powerful number to motivate a challenge. The single person discount is applied to both bands for a fair comparison.
How to Challenge tab
Follow the six-step guide to challenging your band through the Valuation Office Agency (England and Wales) or the Scottish Assessors Association. Read the warning carefully before proceeding — challenging your band is not risk-free.

The Formula
Council tax is calculated by multiplying the Band D rate set by your local council by the ratio for your band:
Band ratios (same for England, Scotland and Wales A–H):
A = 6/9 B = 7/9 C = 8/9 D = 9/9 E = 11/9 F = 13/9 G = 15/9 H = 18/9
I (Wales only) = 21/9
Single person discount: Annual bill × 0.75
Example (England, Band D, no discount):
£2,280 × 9/9 = £2,280 per year
Example (England, Band C, single person):
£2,280 × 8/9 × 0.75 = £1,520 per year
The Band D rate is set annually by each local council. The national averages used in this calculator are: England £2,280, Scotland £1,579, Wales £2,170 for 2025/26. Your actual bill will differ based on your specific council's rate.
Example
David and Sarah — 3-bed semi, Leeds
David and Sarah bought a three-bedroom semi-detached in a Leeds suburb. Their council tax bill shows Band E. They wonder if this is correct given what similar houses sold for in 1991.
Checking the band
Potential saving
David researches sold prices from 1991 on Zoopla and finds a comparable three-bed semi on the same street that sold for £69,500 in April 1991. This strongly suggests Band D is correct. They submit a band review to the VOA — but first check the "How to Challenge" tab to understand the risks.
