Does your home's size match its band?
Council tax bands were set on 1991 values, so a home that's small for its band often signals an overbanding. Enter your postcode, band and — if you know it — your floor area, and we'll place you against the typical home in your area using open EPC and Valuation Office data.
Why this is only a hint
This compares you to the area, not your actual neighbours — a strong hint, not a verdict. Two similar homes next door can sit in different bands, and that's what wins a challenge. The free address check pulls the real per-address bands around you for a true like-for-like comparison. Your floor area is on your home's EPC (free to look up).
