Just moved in? Your right to challenge your council tax band within 6 months

Most people who challenge their council tax band do so on the basis of comparable evidence — nearby properties in a lower band. That route is open to anyone, at any time. But if you have recently moved into a property, you have an additional right under the Council Tax (Alteration of Lists and Appeals) Regulations: the right to challenge as a new occupier, sometimes referred to as the "new occupier challenge" or "six-month rule."

What the six-month rule means in practice

Within six months of becoming a new council tax payer at a property — typically, within six months of moving in — you have the right to request a review of the band without needing to demonstrate that the original banding was wrong at the time it was set. The standard review route requires you to show evidence that the 1991 valuation was incorrect. The new occupier route is slightly different: it allows you to initiate a review simply by virtue of being a new occupant.

In practice, you still need evidence to support a successful challenge — comparable properties in a lower band remain the most useful form of evidence. But the threshold for triggering the review process is lower, and the VOA is required to consider your request. The six-month window is your clearest statutory opportunity to get the band looked at from scratch.

Why backdating is more favourable for new occupiers

One of the most significant advantages of challenging within six months of moving in is backdating. For standard challenges, any successful reduction is backdated to the date the challenge was submitted. For new occupier challenges submitted within the six-month window, any successful reduction may be backdated to the date you moved in — not just the date you submitted the challenge.

This distinction matters. If you move in on 1 January, take four months to review your band, and submit a challenge on 1 May, a successful outcome may be backdated to 1 January — giving you four months of additional refund compared to if you had waited.

What counts as "moving in"?

The six-month clock starts when you become liable for council tax at the property — typically, your tenancy start date or completion date if you bought. If you moved in through a gradual process (for example, a long period between exchange and completion), the relevant date is when council tax liability transferred to you, not when you physically occupied the property.

If you are unsure of the precise date, check your council tax bill — it will show when your liability began at the property.

What to do if the previous occupant already challenged

It is worth checking whether the previous occupant challenged the band before you moved in. If they did and the challenge was successful, the band may already have been reduced — and you may be benefiting from it already. If the challenge was unsuccessful, or if a review was initiated but not completed before they moved out, the position may be more complex.

You can check the current listed band on the VOA public register. If the band appears lower than you might expect relative to similar properties, a previous challenge may already have been resolved in the property's favour. If it appears higher than comparable properties, that is your signal that a challenge may be worth pursuing.

Steps to take if you have recently moved in

• Check your current band against comparable properties in your postcode — our tool does this automatically using the public VOA register
• If comparables suggest your band may be wrong, submit a Review of Band request to the VOA as early as possible within your six-month window
• In your submission, note that you are a new occupier — this ensures the VOA applies the correct regulatory framework to your request
• Keep a record of your move-in date and your submission date — both are relevant to any backdating calculation

After six months

If you miss the six-month window, you have not lost the right to challenge your band entirely. The standard comparable-evidence route remains open indefinitely. The difference is that backdating will run from the date you submit your challenge rather than from your move-in date.

In other words, acting within six months of moving in is simply the optimal time to do it — not the only time.
