Is My Council Tax Band Wrong? — Quick Check
Enter your property details to estimate your likely correct band and potential annual saving.
What Is a Council Tax Band?
Council tax in England, Scotland and Wales is based on the estimated value of your property — but crucially, using values from April 1991, not today's prices. Properties are placed into bands A through H (or A–I in Wales), and the band determines how much council tax you pay relative to a Band D property in your area.
The reason this matters: properties were assessed very quickly in 1991, with limited information available. As a result, a significant number of homes were placed in the wrong band — and since council tax bills are sent automatically each year, millions of people have been overpaying without realising it.
Key fact: Approximately 25–30% of council tax band challenges are successful. The average saving from dropping one band is around £291/year in England (Band D to Band C), with savings backdated to when you moved in.

Why Do 1991 Values Still Matter in 2026?
When council tax was introduced in April 1993, every property in England was valued as of 1 April 1991. This was a one-time exercise — and it has never been updated. Unlike in Wales (which revalued in 2005), English properties are still banded using their estimated 1991 values.
This creates anomalies:
Properties that have been extended or improved may be in too high a band
Properties that had structural problems in 1991 may have been undervalued then but not since corrected
Administrative errors during the mass 1991 assessment are surprisingly common
Properties split into flats or merged from flats may have inherited incorrect bands
The government has no plans to revalue English properties for council tax purposes. This means the 1991 reference values remain legally binding indefinitely — making understanding those 1991 prices essential.
How to Check If Your Council Tax Band Is Wrong
1
Look up the VOA website: Visit the Valuation Office Agency (voa.gov.uk) and search for your property. You can see your current band and the bands assigned to neighbouring properties.
2
Compare with neighbours: Find properties in your street with similar size, type and features. If identical properties are in a lower band, yours may be wrong. Check 3–5 comparable properties.
3
Research 1991 property prices: Use the Nationwide HPI historical house price tool or old Land Registry data to estimate what your property type was worth in April 1991 in your area. This gives you an indication of the correct band.
4
Check for structural changes: Was the property converted, extended, or structurally altered after the 1991 assessment? Any changes since the band was set could affect the correct band.
5
Look for errors: Does the VOA record match your property exactly? Check property size, type and description. Errors in these details can lead to incorrect banding.
Grounds for a Successful Council Tax Band Appeal
You can challenge your council tax band if you believe there has been an error. Valid grounds include:
Comparable properties nearby are in a lower band — the most common and successful ground
Administrative error in the original assessment (wrong property size, type or details recorded)
Property has been split or merged since the original banding (e.g. house converted to flats)
Change in the property since assessment — demolition of part of the property, for example
Newly built property placed in the wrong band when first assessed
Material change in the area affecting the property's value (e.g. motorway built nearby)
Important: You cannot appeal simply because house prices have risen or fallen since 1991. The band is based on the relative value of your property in April 1991, not its current market value.
How to Challenge Your Council Tax Band — Step by Step
Step 1: Gather Evidence
Before contacting the VOA, compile evidence: comparable bands from the VOA website, sold prices from Land Registry for similar properties, and any property records you have access to.
Step 2: Use the VOA's Online Challenge Service
In England, go to voa.gov.uk and select "Check and challenge your council tax band." You'll need to create a GOV.UK account. Submit your challenge with your evidence online.
Step 3: Wait for VOA Response
The VOA aims to respond within 12 weeks. They will either agree to move your property to a lower band, disagree and explain why, or ask for more information.
Step 4: Escalate to Valuation Tribunal if Needed
If you disagree with the VOA's decision, you can escalate to the Valuation Tribunal for England (VTE), an independent body that hears appeals. There is no fee to appeal to the Tribunal. The Tribunal hearing is usually held locally and you can represent yourself.
Success rate: Approximately 25–30% of challenges to the VOA result in a band reduction. Of those that reach the Valuation Tribunal, success rates vary widely by circumstance.
How Much Can You Save? Backdating Explained
If your appeal is successful, the band is reduced and any overpaid council tax is refunded or credited. The backdating rules are generous:
New occupier challenge: Backdated to when you moved in, however long ago
Existing occupier challenge: Backdated to when the relevant change occurred
No time limit: Unlike many tax matters, there is no time limit on backdating for council tax band reductions

Council Tax Discounts and Exemptions
25% Single Person Discount
If only one adult lives in a property, a 25% discount applies automatically — but you must claim it from your council. Students and certain other adults (carers, apprentices, etc.) do not count for this purpose.
50% Empty Property or Second Home Discount
Some councils offer discounts for empty or unfurnished properties, though many now charge a premium (up to 200% extra) for long-term empty homes. Check with your local council.
Student Exemption
A property occupied solely by full-time students is 100% exempt from council tax. Part-time students are not exempt.
Severe Mental Impairment (SMI) Exemption
People with a severe mental impairment (including dementia) do not count as adults for council tax purposes. If they live alone, the property is exempt; if with one other adult, that person gets the 25% single discount.
Council Tax Support / Reduction
Low-income households may qualify for Council Tax Support (formerly Council Tax Benefit), which can reduce bills by up to 100% depending on income, savings and council scheme.
Scotland and Wales — Different Systems
Scotland
Scotland uses the same A–H banding letters but with different 1991 value thresholds. Properties are valued by local Assessors (not the VOA). To challenge your band in Scotland, contact your local Assessor. Councils set their own rates, which tend to be lower than comparable areas in England.
Wales
Wales revalued all properties in 2005 (based on April 2003 values) and uses bands A–I, with 9 bands instead of 8. The Valuation Office for Wales (VOW) handles bandings. Welsh councils have more recently faced pressures to revalue, though no full revaluation has taken place since 2005.
Frequently Asked Questions
How do I know if my council tax band is wrong?
Compare your band with similar properties in your street using the VOA website. If neighbours in identical or similar properties are in a lower band, yours may be wrong. Check sold prices from around 1991 using Land Registry data to verify the valuation underlying your band.
How much can I save by appealing my council tax band?
Moving down one band saves significant money. For example, dropping from Band D (average £2,171/year) to Band C (around £1,930/year) saves around £241/year. Crucially, savings can be backdated to when you moved in, potentially resulting in a large lump sum refund worth thousands of pounds.
How long does a council tax band appeal take?
The VOA aims to respond to challenges within 12 weeks. If you cannot reach agreement with the VOA, you can escalate to an independent Valuation Tribunal, which can take several months longer. Complex cases can take 12–18 months in total.
Can I appeal my council tax band at any time?
You can request a review of your council tax band at any time. You can formally challenge it when you first move into a property, when there has been a change to the property, or if you believe there has been an administrative error. There is no time limit on backdating for successful appeals.
What happens if my appeal is successful?
If successful, your band is reduced and any overpayments are refunded or credited by your local council. The reduction is backdated to the date you moved in (for a new occupier challenge) or to the date of the relevant change, potentially resulting in a significant lump sum repayment.
Can my council tax band go up if I challenge it?
Yes, in theory the VOA could increase your band if a review reveals it is too low. However, this is very rare in practice. The VOA will always inform you before making any upward change, giving you the option to withdraw your challenge before the increase takes effect.
Are council tax bands the same in Scotland and Wales?
No. Scotland uses the same A–H letters but different 1991 value thresholds, administered by local Assessors rather than the VOA. Wales revalued in 2005 and uses Bands A–I with completely different thresholds based on 2003 values. Each country has its own appeals process.
