Some households may be in the wrong Council Tax band. In the year to March 2024, 27% of challenges resolved by the Valuation Office led to a lower band.

Council Tax bands in England are based on what a home would have sold for on 1 April 1991. In Wales, they're based on values at 1 April 2003. If your band doesn't match similar homes nearby, or the evidence suggests it's too high, you can ask for it to be reviewed.

This guide covers England and Wales, where bands are set by the Valuation Office (part of HMRC since 1 April 2026). In Scotland, bands are set by local Assessors; you can find yours through the Scottish Assessors Association. Northern Ireland uses domestic rates instead of Council Tax.

Odds of Success for Council Tax Challenge

The latest official figures cover 1 April 2023 to 31 March 2024 (Valuation Office statistics, published 29 August 2024). The Valuation Office received 43,820 challenges and resolved 39,590 in that year; 14,160 remainined outstanding. Of those resolved, 27% led to a lower band, 65% led to no change and less than 1% led to a higher band.

Each year, there are also challenges that remain outstanding, accounting for the missing figures if you tally the numbers up.

Percentages are of challenges resolved in the year. Figures are rounded to the nearest 10 by the Valuation Office. Other outcomes (such as a property being deleted from the list, split or merged) make up the remainder.

Ten band reviews (less than 1% of those resolved) led to a higher band.

The Valuation Office also resolved 3,350 appeals in the same year. In England, for appeals linked to proposals resolved in 2023-24, 43% led to a lower band and 46% to no change (provisional figures). In Wales, 250 of 1,150 resolved appeals (22%) led to a lower band and 670 (58%) to no change.

Statistics for the years to March 2025 and March 2026 are scheduled for publication in October 2026.

Why some homes may be in the wrong band

Council Tax started on 1 April 1993, and most homes in England were banded using estimated 1991 values. Bands in England haven't been revalued since. Wales was revalued using 2003 values. Because of how long ago these valuations were made, and because homes and areas have changed since, some bands may not match similar neighbouring properties.

Council Tax band values

England (values at 1 April 1991):

• Band A: up to £40,000

• Band B: £40,001 to £52,000

• Band C: £52,001 to £68,000

• Band D: £68,001 to £88,000

• Band E: £88,001 to £120,000

• Band F: £120,001 to £160,000

• Band G: £160,001 to £320,000

• Band H: over £320,000

Wales (values at 1 April 2003):

• Band A: up to £44,000

• Band B: £44,001 to £65,000

• Band C: £65,001 to £91,000

• Band D: £91,001 to £123,000

• Band E: £123,001 to £162,000

• Band F: £162,001 to £223,000

• Band G: £223,001 to £324,000

• Band H: £324,001 to £424,000

• Band I: over £424,000

Each band pays a fixed proportion of the Band D charge. For example, Band C pays eight-ninths of Band D. Based on the average Band D in England for 2026-27 of £2,392 (MHCLG, 25 March 2026), dropping from Band D to Band C would reduce the bill by about £266 a year. Your own council's charges will differ.

How to check your band

Before you challenge, it helps to gather evidence:

Step 1: The Neighbour Check

First, check if you're paying more than your neighbours for similar properties:

• Check your Council Tax band on GOV.UK by entering your postcode.

• Compare your band with homes of the same type (for example, semi-detached), size, age and style in the same street or estate (or the same village or area in rural locations).

• A neighbour being in a lower band doesn't necessarily mean your band is wrong. Their band could be the one that's incorrect, or there may be differences you can't see.

Step 2: The Valuation Check

Next, estimate what your property was worth in 1991 (when the council tax bands were set):

• You can use a house price index calculator, such as the Nationwide house price calculator, to estimate what your home might have been worth in 1991 (England) or 2003 (Wales), then compare it with the bands above.

• This is only a rough guide. GOV.UK says the Valuation Office won't treat average house price information from sites such as Nationwide, Rightmove or Zoopla as strong evidence.

Building Your Case

If these checks suggest you're in the wrong band, there are two alternate ways of challenging:

1. Proposal (when you have a legal right to challenge)

You have a legal right to challenge your band if:

• you've been paying Council Tax on the property for less than 6 months, or

• the Valuation Office has changed your band in the last 6 months, or

• your property or the local area has changed (for example, part of the property has been demolished, or there's been a change in the area that affects its value).

2. Band review (when you don't have a legal right to challenge)

If none of the above applies but you think your band is wrong, you can ask for a band review. You'll need evidence, such as:

• the addresses of up to 5 similar properties in a lower band, or

• sale prices of similar properties sold between 1 April 1989 and 31 March 1993 (England) or between 1 April 2001 and 31 March 2005 (Wales), with addresses and sale dates.

How to make a challenge

Before you challenge, be aware that the Valuation Office can also move your band up if it finds it's too low.

To make your challenge:

• Use the Valuation Office's online service for properties in England and Wales, or email ctainbox@hmrc.gov.uk.

• You must keep paying your Council Tax while the challenge is reviewed.

• You can challenge directly without using a paid company. Firms that offer to do this for a fee have no special powers with the Valuation Office.

If they agree your band is wrong, they'll correct it and you'll a refund depending on the effective date of the reduction and when you became liable for council tax for the property.

What happens next

• The Valuation Office usually confirms it has received your challenge within a few days, but it can take up to 28 days.

• A decision can take up to 4 months if you had a legal right to challenge, or up to 12 months for a band review.

• If your band changes, the Valuation Office tells your council, which revises your bill and pays any refund due.

• Your band can go down, stay the same or, less often, go up.

• If you had a legal right to challenge and disagree with the decision, you can appeal to Valuation Tribunal England within 3 months or Valuation Tribunal Wales within 4 months of the decision. Appealing is free, but you pay your own associated costs.

Refunds

• In England there's no time limit on backdating a band reduction, so a refund can go back to when you became responsible for the bill (or April 1993, if later).

• In Wales, a reduction for a band that was too high can't be backdated more than six years.

• Councils can't pay interest on refunds from a band change.

Things to know before you challenge

• Extensions or improvements made since the valuation date don't change your band until the property is sold (or let on a lease of 7 years or more). Bands use April 1991 prices in England and April 2003 prices in Wales. Later property changes can affect banding, subject to rules about when those changes are taken into account.

• Evidence based only on current values or your neighbours' bands is weaker than comparable properties or sale prices from around the valuation date.

• Keep copies of everything you submit and note the date you sent it.

• Deadlines matter: 6 months for a proposal as a new bill payer, and 3 months (England) or 4 months (Wales) for an appeal.

Other ways your bill might be reduced

These are separate from your band and are handled by your council:

• 25% off if you're the only adult living in the home.

• Households where everyone is a full-time student don't pay Council Tax.

• The Disabled Band Reduction Scheme can reduce your bill to the band below (or by 17% in Band A).

• Council Tax Reduction for people on low incomes.

• Empty homes: any discount is up to your council, and some councils charge extra on long-term empty homes.

Where to get help

• Your local council, for bills, discounts and refunds.

• The Valuation Office, for questions about your band (get extra support).

• Citizens Advice, for free, independent guidance.
