Is your council tax band wrong?

Your band is based on what the property was worth on 1 April 1991 in England, or 1 April 2003 in Wales.

Most bands were set in a single pass in 1993 by valuers working at speed, often from the pavement. Some were guessed, and the guess has never been revisited.

You can ask for it to be looked at again, free, and you can do it yourself in about 40 minutes. There is no fee and no need for anyone to act for you.

This is 1 of 31 Checks in the ClaimPilot rule library. The whole answer is below, including the free route. Nothing on this page needs paying for.

Estimated ranges are estimates, never promises. The figure you actually receive depends on your own circumstances and on the body you send the letter to.

01

Who this applies to

  • Your home is in England or Wales, so the Valuation Office handles it. In Scotland you go to your local assessor instead.
  • Similar neighbouring homes are in a lower band than yours.
  • You can find what homes on your street sold for near the 1991 or 2003 valuation date.
  • Or something changed: the property was split or merged, its use changed, or the area changed physically.

02

What it is worth

Band ratios are fixed in law, so the saving is arithmetic rather than guesswork. Band D is the reference point.

One band lower cuts your bill by one ninth of the band D charge in your area, every year. Where band D is £1,800–£2,400, that is roughly £200–£270 a year.

If the band was wrong from the start, a correction can be backdated to when the error began — in some cases as far as 1993.

03

The free route, step by step

You can do all of this yourself, free, today. We are not in the middle of it and we take no share of it.

  1. 01Look up your own band, and the bands of similar homes on your street, on the Valuation Office council tax list. It is public and free.
  2. 02Find sale prices for those homes near 1 April 1991 (England) or 1 April 2003 (Wales), then adjust for the difference in property.
  3. 03If you have a legal right to challenge, submit a formal proposal. If you do not, ask for a band review instead. Both go through the same GOV.UK page.
  4. 04Keep paying your current bill while it is looked at. A reduction is refunded to you afterwards.

04

Evidence you will need

  • Your council tax reference and current band
  • Addresses and bands of 3 to 5 comparable neighbouring homes
  • Sale prices for those homes near the valuation date, from the Land Registry price paid data
  • The date you became the council tax payer, if you have been there under 6 months

ClaimPilot never asks for any of this. The Scan asks about circumstances, not identity, and no letter is pre-filled with data we did not need.

05

What to watch for

  • A review can move the band up. Of 39,590 challenges resolved in the year to March 2024, 65% saw no change, 27% were reduced and under 1% went up (VOA, 2024).
  • You have a legal right to make a formal proposal only in defined situations, including within 6 months of becoming the council tax payer. Otherwise it is a band review, which the Valuation Office is not obliged to accept.
  • Poor repair is not a ground. The property must be derelict or in serious disrepair to come off the list.
  • Nobody can guarantee a reduction, and no firm needs to be paid a share of one.
