Think your Council Tax band is wrong? How to check and challenge it

Council Tax bands are based on what your home was worth in 1991 or 2003

Your Council Tax band reflects what your home would have sold for on a fixed date, not what it is worth today. According to GOV.UK, bands in England are based on the value on 1 April 1991 and in Wales on 1 April 2003. The Scottish Assessors say bands in Scotland also reflect the open market value at 1 April 1991, under a number of statutory assumptions.

The Valuation Office Agency (VOA), part of HMRC, sets bands in England and Wales. It says it looks at size, layout, character, location and any change of use, as well as the value on the valuation date. In Scotland, a local assessor sets the band.

No one valued every home in 1991. Assessors compare your home with similar homes that sold around the valuation date, and the Scottish Assessors point out that two homes that look alike can end up in different bands because each band covers a range of values. That is also how mistakes happen, and why checking your neighbours is the first step.

Check your band and your neighbours' bands on GOV.UK

You can look up the band of any home in England or Wales, not just your own, with the free Check your Council Tax band service on GOV.UK. Search by postcode and you will see every address on the street with its band. For homes in Scotland, search on the Scottish Assessors Association website instead.

Compare your home with others of the same type, size, age and style. GOV.UK asks for exactly this kind of comparison when you request a review. Useful checks:

• Are identical houses on your street, built at the same time, in a lower band?
• Is your flat in the same band as larger flats in the same block?

One house in a lower band is weak evidence, because it may be the one that is wrong. A pattern is stronger: if most three-bedroom semis on the estate are in Band C and yours is in Band D, that is worth raising.

You do not need to pay a company to challenge your band for you. The GOV.UK service is free, and GOV.UK says you can use it whether or not you have a legal right to challenge.

The grounds for a challenge decide how strong your case is

GOV.UK splits challenges into two types, and which one you can make depends on your situation.

A proposal, where you have a legal right to challenge

According to GOV.UK, you have a legal right to challenge (called making a proposal) if you think your band is wrong and either you have been paying Council Tax on the property for less than 6 months, or the Valuation Office changed your band in the last 6 months. You also have this right if:

• the property has changed, for example it has been split into flats or merged into one;
• part of it is now used for business;
• the local area has changed physically, for example a new main road or supermarket has been built nearby;
• it should be removed from the list because it is derelict or being fully renovated, or added because it has no band.

A band review, where you do not

If you have been paying for more than 6 months and nothing has changed, you can still ask for a band review, but you must supply evidence. GOV.UK asks for the addresses of up to 5 similar properties in a lower band, in the same street or estate (or the same village or area in the countryside).

You can also use sale prices. GOV.UK accepts sales between 1 April 1989 and 31 March 1993 for England and 1 April 2001 and 31 March 2005 for Wales. If your home or a similar one sold in that window for less than the top of a lower band, that supports your case. The VOA will not treat average price data from sites such as Rightmove, Zoopla, Nationwide's House Price Index or Nethouseprices as strong evidence.

Some reasons never work. GOV.UK says you cannot appeal because you think your bill is too expensive, and in Scotland the assessors say a fall in value from a housing market downturn does not count.

A challenge can move your band up as well as down

Your band can go up after a challenge, and so can your neighbours'. According to the Valuation Office Agency (blog post of 3 March 2026), "if the evidence shows that the value of your property is higher than originally decided, your property may be moved into a higher band". When one band changes, the VOA may also review similar homes nearby to keep the list accurate.

Before you apply, check whether your home has been extended or improved since it was banded. The VOA says it cannot legally change the band of an improved home until it is sold or there is a general revaluation, so an extension added by you does not raise your band now. But if a previous owner extended the house before selling it to you, the VOA can take that into account.

A simple test: if your home is clearly bigger or in a better position than the lower-banded homes you plan to name, your challenge is more likely to fail, and it could fail upwards.

Worked examples: what moving one band saves in 2026/27

Every band is a fixed fraction of Band D. In England and Wales, Band C is 8/9 of Band D and Band E is 11/9; in Scotland, Band C is 320/360 and Band E is 473/360. So moving from Band D to Band C saves one ninth of the Band D charge in England and Wales, and 40/360 in Scotland.

The figures below use the average 2026/27 Band D for a home with two adults in each council area, from the government statistics behind our Council Tax calculator: MHCLG for England (including the average parish precept), the Welsh Government for Wales (including the average community council precept) and the Scottish Government for Scotland (excluding Scottish Water charges). Your own bill depends on your parish or community council and any discounts.

Worked example, Birmingham. Your terraced house is in Band D and pays £2,362.90 a year. Four identical houses on the street are in Band C. If the VOA agrees and moves you to Band C, your bill becomes £2,362.90 × 8/9 = £2,100.36, a saving of £262.54 a year, or £1,312.70 over five years at 2026/27 rates. If instead the review found your house was worth more and moved it to Band E, you would pay £2,362.90 × 11/9 = £2,887.99, which is £525.09 a year more. The downside is twice the upside.

Worked example, Scotland. The gap is wider in Scotland above Band D, because Scotland uses steeper ratios for Bands E to H: Band E is 473/360 of Band D, against 11/9 in England and Wales. In the City of Edinburgh, Band E costs £2,136.45 against £1,626.05 for Band D in 2026/27, so a successful challenge from E to D saves £510.40 a year, and a move from D to E costs the same.

Keep paying your current bill while the challenge runs

You must keep paying Council Tax at your current band while your challenge is reviewed. GOV.UK says this applies for the whole time the challenge is being reviewed.

If your band is lowered, GOV.UK says the VOA tells your council, which revises your bill and pays any refund due. Keep your bills and payment records so you can check the refund.

Disputes about the bill rather than the band go to your council, not the VOA. According to GOV.UK, you write to the council if you think the amount, the person billed or a discount is wrong, and it has 2 months to reply. You must keep paying the amounts on your original bill until a new one arrives.

How long a challenge takes, and appealing to the Valuation Tribunal

According to GOV.UK, the VOA usually acknowledges a challenge within a few days, though it can take up to 28 days. It can then take:

• up to 4 months to decide a proposal, where you had a legal right to challenge;
• up to 12 months to decide a band review.

The VOA will change your band, remove or add the property, or tell you why the band cannot change. You can apply through the online service on GOV.UK, or by email to ctinbox@hmrc.gov.uk if you cannot use it.

You can appeal only if you made a proposal. A band review has no appeal. GOV.UK says to appeal to the Valuation Tribunal for England within 3 months of the decision, or the Valuation Tribunal for Wales within 4 months. The tribunals are independent of the VOA and free, though you pay your own costs such as travel or an agent. You can ask for more time if you explain why you need it.

Scotland uses local assessors and its own deadlines

In Scotland, you challenge your band with the local assessor at your Valuation Joint Board or council, not the VOA. According to the Scottish Assessors, the owner or the person liable to pay can make a proposal:

• within 6 months of becoming the owner or liable person;
• within 6 months of the assessor issuing a notice of banding;
• within 6 months of a First-tier Tribunal decision on a comparable home that gives reasonable grounds to change yours;
• at any time if there has been a material reduction in value, such as part demolition, a physical change in the area, or adaptation for a disabled person.

The assessor must acknowledge a proposal within 14 days and has up to 6 months to decide. If you disagree, you can appeal to the First-tier Tribunal for Scotland Local Taxation Chamber within 6 months plus 6 weeks of the date the assessor received your proposal. If the assessor makes no decision in 6 months, you have 6 weeks after that to appeal.

The Scottish Assessors say a material increase in value from building work only changes the band from the date the home is next sold.

Wales is revaluing, and some households can pay one band lower without a challenge

Wales has a Council Tax revaluation planned in law. According to the Welsh Government, the Local Government Finance (Wales) Act 2024 allows revaluations every 5 years beginning from 2028, so Welsh bands based on 2003 values are due to change. If you live in Wales and your case is borderline, weigh a challenge now against a new band that may follow.

A band challenge is not the only way to pay less. Under the Disabled Band Reduction Scheme, GOV.UK says your bill is reduced to the next band down if a disabled adult or child lives in the home and you need an extra bathroom, kitchen or other room, or extra space for a wheelchair. A Band D home pays the Band C rate; a Band A home gets a 17% discount. Apply to your council, not the VOA.

In Birmingham, that reduction is worth the same £262.54 a year as a successful Band D to C challenge, with no risk of the band going up. Check both in the Council Tax calculator.
