When will I know my new council tax band in Wales?

The new council tax bands, based on the revaluation, are expected to be published before they come into force in April 2028. The Welsh Government will provide more details closer to the time.

Will my council tax bill definitely go up?

Not necessarily. The revaluation is designed to be 'revenue-neutral' overall, meaning it redistributes the tax burden, not just increase it for everyone. While some properties will move to a higher band and see an increase, others may move down or stay the same.

Can I appeal my new band after the revaluation?

Yes, there will be a formal process to appeal your new council tax band after the revaluation list is published. However, checking and correcting any errors with your current band now can provide a more accurate starting point for the new system.

Is the single person discount being scrapped in Wales?

The Welsh Government reviewed all discounts, including the 25% single person discount. They have confirmed that this discount will be kept. [3]

What the Welsh Council Tax Revaluation Means For You

The Welsh Government is revaluing all 1.5 million domestic properties in Wales, with new council tax bands set to be used from 2028. [2, 8] This revaluation aims to create a fairer system by updating property bands based on more current values, but it creates uncertainty for homeowners.

What is the council tax revaluation in Wales?

For the first time since 2005, every home in Wales is being revalued for council tax purposes. [9, 13] The current system is based on what a property was worth back on 1 April 2003. [9] The revaluation, undertaken by the Valuation Office Agency (VOA), will set new bands based on more up-to-date property values. [13]

The Local Government Finance (Wales) Act 2024 has paved the way for this change, with the first new valuation list set to take effect from April 2028. [3] Following this, revaluations will happen every five years to ensure the system keeps pace with the property market. [3]

Why should I check my band before the revaluation?

Checking your current council tax band now is crucial. The revaluation process will be based on the VOA's existing data for your property. If there is an error in that data, it could be carried forward into the new system, potentially locking you into an incorrect higher band for years to come.

Challenging your band now is based on the historic 2003 valuation date. [9] This evidence can often be simpler to find than arguing about a more recent valuation. If your challenge is successful, you could receive a refund for past overpayments and, crucially, ensure your property has a correct baseline before the new valuations are applied.

An incorrect band now could lead to an incorrect band after the revaluation. Securing the right band today is the best way to prepare for the upcoming changes.

How will the new council tax bands be calculated?

The VOA is assessing properties across Wales to assign them a new valuation. [13] The Welsh Government intends for the revaluation to be 'revenue-neutral' overall. [2] This means it is not designed to raise more tax in total, but to redistribute the burden more fairly based on how property values have changed relative to each other since 2003. [2]

Some properties will move into higher bands, while others may move down. The government will also define new band thresholds before the changes come into effect. [5]

What if my property has been improved?

Under the current system in England and Wales, improvements like an extension do not affect your council tax band until the property is sold. This is known as the 'improvement indicator'.

A full revaluation is different. The VOA will assess the value of your property as it stands at the valuation date. This means that any significant improvements you have made could be factored into the new valuation, potentially moving your property into a higher band even if you have not sold it.

How do I challenge my council tax band in Wales?

The process for challenging your band remains the same for now. You do not have to pay for this service.

Gather Evidence: Check the council tax bands of similar properties in your street using the VOA's online service. [9] If neighbours in identical or very similar homes are in a lower band, you may have a case.
Contact the VOA: Submit a challenge to the VOA online. [19] You will need to provide evidence explaining why you believe your band is incorrect, such as the addresses of lower-banded neighbouring homes.
Appeal to the Tribunal: If the VOA rejects your challenge, the case is automatically reviewed by the Valuation Tribunal for Wales. [18] This is an independent body that will make a final decision. [4]

It is important to continue paying your council tax as billed while you are undergoing a challenge. [9] If your appeal is successful, your council will adjust your bill and arrange a refund for any overpayments. [4]

Is England having a revaluation too?

No. The UK government has no current plans for a council tax revaluation in England, where bands are still based on 1991 property values. [16, 19] This major change is only happening in Wales, making it especially important for Welsh homeowners to understand the implications and check their current banding. [2, 16]
