When Should You Challenge Your Rateable Value?
Challenging a rateable value is not always straightforward- but in certain circumstances, a structured review can result in a lower ongoing bill and a backdated refund from 1 April 2026.
Understanding when a challenge is worth pursuing, and when it is not, helps avoid unnecessary appeals while ensuring genuine over-assessments are not overlooked.
For a full explanation of how the formal appeal process works at each stage, see our Business Rates Appeal guide
Common Reasons to Consider A Challenge
The strongest grounds for a challenge exist where there is clear evidence that the rateable value does not reflect what the property could have achieved in rent at the April 2024 valuation date.
Specific situations that may support a challenge include:
-
Comparable properties nearby are assessed at materially lower levels — particularly if similar properties in the same street or scheme have rateable values 15% or more below yours.
-
Your current passing rent is significantly below your rateable value — especially if a recent lease was agreed at arm's length and reflects genuine market conditions at or around April 2024.
-
Market rents in your area fell between 2021 and 2024 and the evidence used to set your rateable value does not reflect this.
-
Structural or physical changes to the property have reduced its rental value — such as loss of car parking, reduced floor area, or changes to layout or access.
-
A neighbouring development, road change, or infrastructure project has materially affected visibility, footfall or accessibility.
If the change is a physical or environmental one that has occurred since the valuation date, it may also qualify as a Material Change of Circumstances (MCC), which operates through a separate route.
Does the 2026 revaluation give me grounds to challenge?
The 2026 revaluation took effect on 1 April 2026 and used a valuation date of 1 April 2024. If you believe your new rateable value does not accurately reflect what your property could have achieved in rent at that date, you can challenge it now — you do not need to wait for the next revaluation in 2029.
Common grounds following the 2026 revaluation include:
-
Your rateable value increased significantly but comparable properties nearby show smaller increases or reductions.
-
The rental evidence used to assess your property appears inconsistent with lease transactions in your area around April 2024.
-
Your sector experienced a material downturn between 2021 and 2024 that is not reflected in the assessment — particularly relevant for some retail, office and industrial markets where rental growth was uneven.
If the revaluation pushed your rateable value above the Small Business Rate Relief (SBRR) threshold of £15,000, a successful challenge that brings it back below that threshold could restore your full or partial relief entitlement.
Note: a general increase in rateable value across your sector is not in itself grounds for a challenge. The evidence needs to be property-specific. A free eligibility check is a useful first step to understand whether your property's position looks unusual compared with similar properties.
Situations where a challenge is unlikely to succeed
Not every business under financial pressure has grounds for a challenge. The following factors do not, on their own, support a reduction in rateable value:
-
General economic downturn or inflation affecting the sector broadly.
-
Rising interest rates or increased operating costs.
-
Reduced profitability or turnover — for most property types, rateable value is based on rental evidence, not trading performance.
-
Sector-wide trading decline where rental evidence at the valuation date does not reflect this.
These are treated separately from property-specific changes. A challenge that lacks supporting rental or comparable evidence is unlikely to progress beyond the initial Check stage.
How the Check, Challenge, Appeal process works
The statutory route for challenging a rateable value in England is the HMRC Valuation Office's Check, Challenge, Appeal (CCA) process.
-
Check — you submit the property details and confirm or correct the factual information held by the HMRC Valuation Office. This is the starting point and must be completed before a Challenge can be submitted.
-
Challenge — once the Check is complete, you can formally submit a Challenge with supporting evidence for a lower rateable value. The HMRC Valuation Office reviews the evidence and either agrees a revised value or maintains the current assessment.
-
Appeal — if the Challenge is not resolved satisfactorily, you can appeal to the independent Valuation Tribunal. This stage is less common and typically used where a significant saving justifies the additional process.
Timing matters. Any reduction agreed at Challenge or Appeal is typically backdated to the date the Check was submitted — so acting promptly preserves the full refund potential from 1 April 2026.
How long does a business rates challenge take?
Timescales vary depending on the complexity of the case and workload at the HMRC Valuation Office.
As a general guide:
The Check stage is typically acknowledged within a few weeks and can take several months to complete.
The Challenge stage can take six to eighteen months, particularly for contested cases requiring comparable analysis.
Any reduction agreed is backdated to the date the Check was submitted, not the date it is resolved — which is why submitting promptly matters more than the time taken to conclude.
Could challenging my rateable value make things worse?
In most straightforward cases, a challenge does not trigger an automatic review that could lead to an increase. However, there are circumstances where this risk exists:
If improvements or beneficial alterations have been made to the property since the valuation date, a review could result in an upward revision.
For specialist properties where trading evidence is used in the valuation, a stronger trading performance since the valuation date could support a higher assessment.
A well-prepared eligibility check and specialist review before submitting a formal challenge helps identify this risk before it becomes a problem.
Revaluation vs challenge — what is the difference?
A revaluation is a national reset applied to all properties at the same time. It is carried out by the HMRC Valuation Office and cannot be opted out of.
A challenge is specific to your individual property. It is initiated by you or your representative and argues that the rateable value assigned to your property is incorrect based on available evidence.
You can challenge at any point during a rating period — you do not need to wait for the next national revaluation. The next revaluation is expected in 2029.

Should you use professional representation?
Businesses can pursue the Check, Challenge, Appeal process directly without professional help. However, professional representation may add value where:
-
The case involves complex comparable evidence or specialist valuation methodology.
-
The rateable value is high enough that a small percentage reduction produces a significant saving.
-
The challenge involves a portfolio of properties where consistent evidence needs to be prepared across multiple sites.
Some representation arrangements operate on a no win no fee basis, meaning fees are only payable on a successful outcome.
