How long does a council tax band challenge take?

The Valuation Office Agency (VOA) aims to make a decision within two months of receiving all your evidence. However, complex cases can sometimes take longer. Your local council will then be notified to adjust your bill and process any refund due.

Can my council tax band go up if I challenge it?

Yes, there is a risk your band could be increased. A challenge triggers a full review by the VOA, and if they find your property should be in a higher band, they can change it. Thorough research into neighbouring property bands is crucial to avoid this.

What if the VOA rejects my challenge?

If you disagree with the VOA's decision, you can appeal to the independent Valuation Tribunal. You must submit your appeal to the tribunal within three months of the date of the VOA's decision letter.

Will challenging my band affect my neighbours?

Your challenge is specific to your property. However, if your proposal highlights a wider error across a street or estate, the VOA may decide to review the bands of other nearby homes, which could lead to their bands changing.

How to Check Your Council Tax Band and Get a Refund

You can check your council tax band for free on the GOV.UK website by entering your postcode. To see if it is incorrect, compare your band with similar neighbouring properties. If this research suggests your band is too high, you can then submit a challenge to the Valuation Office Agency (VOA).

Why should I check my council tax band now?

With council tax rates rising for millions of households, ensuring you are not overpaying is more important than ever. A recent report revealed that in the 2023-24 financial year, over 35,000 properties in England and Wales had their council tax bands lowered after a challenge. This highlights that banding errors are common and successful appeals are achievable.

These figures from the Valuation Office Agency (VOA) show that thousands of homeowners discovered they were in the wrong band and are now paying less. More importantly, many will have received a refund for years of overpayments. Checking your band is a straightforward process that could save you a significant amount of money.

How were council tax bands originally decided?

The current council tax system in England and Wales is based on property valuations conducted in 1991. Assessors were tasked with assigning one of eight bands (A-H in England, A-I in Wales) to every home based on its estimated market value at that specific time. The bands were based on the following 1991 property values:

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: More than £320,000

Because of the vast number of properties, many valuations were done quickly, sometimes as 'drive-by' assessments without internal inspection. This haste led to mistakes, especially on streets with a mix of property types and sizes, and these errors from over 30 years ago still affect homeowners' bills today.

How do I check my council tax band for free?

You can perform an initial check of your council tax band yourself. It is a simple, two-stage process of checking your own band and then comparing it with your neighbours.

First, go to the official service on the GOV.UK website. Simply enter your postcode, find your address in the list, and it will show you which band your property is in. Make a note of this.

Next, use the same tool to look up the addresses of nearby properties that are physically similar to yours in size, style, and age. Note down their bands. If you find that these comparable properties are in a lower band than yours, you may have grounds for a challenge.

What evidence do I need to challenge my band?

A challenge, which is also known as making a 'proposal', requires you to provide evidence to the VOA. A simple belief that your band is wrong is not enough. The VOA needs facts to support your case.

Compelling evidence usually includes:

Addresses of comparable properties: Find at least five nearby properties that are similar to yours but are in a lower council tax band. The VOA will place most weight on this evidence.
Property prices from 1991: If you know what your home, or similar homes nearby, sold for around April 1991, this can be powerful evidence. You might find this information through old property listings or Land Registry data.
Changes to the property or area: Your property's value may have been negatively affected by a change since 1991, such as a new motorway being built nearby or the demolition of part of the property.

Gathering this evidence is the most critical part of the process. The stronger your evidence, the higher your chance of a successful outcome.

What happens if my band is lowered?

If the VOA agrees with your proposal and lowers your council tax band, two things happen. First, your local council will issue you a new, lower council tax bill for the future. You will start paying the correct, lower amount immediately.

Second, you should receive a refund for the amount you have overpaid. This refund is backdated to the date you moved into the property (or April 1993, when the system began, whichever is more recent). Your local council is responsible for calculating and processing this refund.

Are there any risks to challenging my council tax band?

Yes, there is a small but important risk you must consider. When you ask the VOA to review your band, they look at it afresh. This review could result in one of three outcomes: your band is lowered, it stays the same, or it is raised.

An increase is rare, but it can happen if your initial research was flawed and the VOA finds that your property was actually undervalued. For example, if your neighbours in identical homes are all in a higher band, challenging your band could lead to it being increased to match theirs.

This is why it is essential to do thorough research before submitting a challenge. If there is any doubt, seeking expert advice can help you assess the potential risks and strengths of your case before proceeding.
