What Is A Business Revaluation?
A business rates revaluaiton is a national reassessment of the rateable values carried out periodically to reflect changes in the property market.
Revaluations update the rating list to ensure rateable values better reflect rental evidence at a fixed valuation date.
Understanding how revaluations work help clarify when a review may - or may not - be appropriate.
If you are unsure how rateable values are determined in the first place, see our guide on how rateable values are calculated.
Why Do Revaluations Happen?
Property markets change over time.
​
Rental levels rise and fall depending on:
​
-
Economic conditions.
-
Location demand.
-
Sector performance.
-
Infrastructure changes.
-
Supply and vacancy levels.
​
Revaluations ensure that business rates liabilities reflect updated market evidence rather than historic assumptions.
How Often Do Business Rates Revaluations Occur?
Revaluations occur at set intervals determined nationally.
​
Each revaluation uses a fixed valuation date - meaning assessments reflect market conditions at a specific point in time, not current trading performance.
​
This distinction is important:
​
Revaluation ~ ongoing adjustment for trading conditions.
​
If circumstances change between revaluations, different mechanisms may apply - such as a Material Change of Circumstances (MCC).
Does Revaluation Automatically Reduce My Business Rates?
Not necessarily.
​
At revaluation:
​
-
Some rateable values increase.
-
Some decrease.
-
Some remain broadly unchanged.
​
The outcome depends on how your property's rental evidence compares with market movements in your sector and location.

Revaluation vs Appeal: What's The Difference?
Revaluation is a national reset.
​
An appeal or challenge relate to a specific property.
​
You may consider a challenge if:
​
-
Comparable properties appear assessed differently.
-
There has been a qualifying material change.
-
Rental evidence suggests misalignment.
​
If unsure whether to act, read our guide on when you should challenge your rateable value.
What Happens After A Revaluation?
After a new list is published:
​
-
Businesses can review their updated rateable value.
-
Transitional arrangements may apply.
-
Formal challenge mechanisms remain available.
​
For a step-by-step overview of how reviews progress, see what happens after a business rates review.
Should You Wait For A Revaluation Before Acting?
In some cases, waiting may be appropriate.
​
However, if:
​
-
A material change has occurred.
-
Comparable assessments differ materially.
-
Rental evidence supports a lower value.
​
You may not need to wait.
​
A structured first step is to use a rateable value check tool to assess alignment with market evidence.
Professional Representation & Fee Structures
Businesses may pursue review routes directly or seek representation.
​​
Some arrangements operate on a no win no fee basis, meaning fees are contingent on a successful outcome.
​
Before entering into any agreement, it is important to understand the basis of assessment and evidence required.
