If your business rates bill feels out of step with the property you occupy, the obvious question is: is my rateable value correct? It is a sensible question to ask, because the rateable value sitting behind your bill can have a direct effect on your overheads for years. Many occupiers assume the figure must be right because it appears on an official assessment. In practice, that is not always the case.
A rateable value is the Valuation Office Agency’s opinion of the annual rent your property could have achieved on a set valuation date, assuming a particular set of conditions. It is not simply a reflection of what you currently pay in rent, and it is not a general judgement about whether your premises are good or bad value. That gap between expectation and reality is where many businesses get caught out.
Why asking “is my rateable value correct” matters
For many businesses, rates are one of the largest fixed property costs after rent. If the assessment is too high, you may be paying more than you should. Across a single property that can be frustrating. Across multiple sites, it can become a serious cost control issue.
The difficulty is that an incorrect rateable value does not always announce itself clearly. Some businesses only question it after moving into a property with obvious disadvantages. Others notice that nearby premises appear to be assessed more favourably. Sometimes the issue only comes to light during budgeting, lease events or acquisition due diligence.
Getting clarity matters because business rates are not a minor admin detail. They affect margins, cash flow and forecasting. If you are responsible for finance, estates or property management, checking whether an assessment is fair is part of good commercial housekeeping.
What a correct rateable value should reflect
A correct assessment should be based on the property as it ought to be valued for rating purposes, not on a rough estimate or a broad-brush assumption. That means looking at the actual characteristics of the premises and comparing them with the evidence and valuation approach used for similar properties.
Depending on the type of property, this may involve floor areas, layout, location, frontage, access, condition, use and other physical or trading-related factors. Industrial units, offices, shops, hospitality venues and specialist properties can all be assessed differently. A fair figure in one sector may be completely inappropriate in another.
This is why there is no simple rule of thumb for deciding whether an assessment is correct. Two premises on the same road can have very different values if one has poor access, an awkward layout or restrictions affecting occupation. Equally, two similar-looking properties can be valued on different evidence if one falls into a different category for rating purposes.
Common reasons a rateable value may be wrong
One of the most frequent issues is basic property data. If the recorded floor area is inaccurate, or the property description does not match the premises on the ground, the valuation may be built on the wrong foundation. Small measurement errors can make a material difference, particularly in offices, retail and larger commercial spaces.
Another issue is tone of value. In rating, valuations are often derived from comparable evidence and applied consistently across classes of property. If the adopted level is too high for your type of premises or locality, that can push the assessment above a fair level. This is not always easy to spot without technical review, because the headline figure may appear reasonable until it is tested against the underlying evidence.
Physical disadvantages are also commonly overlooked or underweighted. Poor configuration, low eaves, limited loading, restricted parking, difficult upper-floor access, outdated fit-out or inferior location within an estate can all affect value. If those factors are not properly reflected, the result may be an inflated assessment.
Material changes matter too. Roadworks, loss of access, nearby redevelopment, changes to the surrounding area or alterations to the property itself may affect rateability. Timing is important here. Some changes can be grounds for review, while others are treated differently depending on the rating list and the circumstances involved.
Is my rateable value correct if my rent is lower?
Not necessarily. A lower passing rent does not automatically mean the rateable value is excessive, and a higher rent does not automatically mean it is too low. Rating valuations follow statutory assumptions and valuation dates that do not always line up with your lease terms or current market conditions.
That said, actual rent can still be relevant evidence in the right context. If your rent, lease terms and property circumstances point to a clear mismatch with the assessment, it may support further investigation. The key word is context. A single rent figure on its own rarely tells the full story.
This is one area where businesses often lose time by relying on instinct alone. The better approach is to test the assessment properly rather than assume that any gap between rent and rateable value proves an error.
Signs it is worth reviewing your assessment
You do not need to wait for a crisis to check whether your figure looks fair. A review is often sensible if your premises have changed, if you have taken on a new property, or if you are responsible for a portfolio and want confidence that liabilities are being managed properly.
It is also worth looking more closely if your property has unusual drawbacks, if your bill increased sharply after a revaluation, or if similar nearby occupiers appear to be treated differently. None of these points guarantee that the valuation is wrong, but they are good reasons to have it examined.
For multi-site businesses, consistency is another clue. If comparable properties within your own estate are assessed on markedly different levels without an obvious reason, that may indicate a wider issue.
How to check whether your rateable value is correct
Start with the basics. Confirm that the property description, floor areas and any recorded features match the premises you actually occupy. It is surprising how often technical inaccuracies begin here.
Then look at the broader valuation context. What type of property is it? How are similar premises in the area assessed? Are there physical or locational factors that should place your property below a standard tone? Has anything changed that might affect value?
This is where specialist input usually becomes valuable. Rating is a technical field, and the right answer depends on evidence, valuation method and case-specific detail. A business owner may know the premises very well, but that is only part of the picture. The assessment has to be tested against rating principles and market evidence as applied by the VOA.
An experienced rating adviser can identify whether there is a genuine basis for challenge or whether the figure is likely to stand. That matters because not every concern leads to a reduction. A measured review saves time and helps you avoid pursuing weak arguments.
What happens if the rateable value looks too high?
If there is evidence that the assessment is incorrect, the next step is to consider a formal challenge through the relevant process. In England, this sits within the Check, Challenge, Appeal framework. The detail and strategy matter. A successful case depends on presenting the right evidence clearly and dealing with technical points properly.
This is not simply an administrative exercise. The strength of a case can turn on valuation analysis, comparables, measurement issues and how the property should be treated in rating law. Some cases are straightforward. Others involve detailed negotiation and careful handling over a longer period.
There is also a judgement to make about timing, prospects and likely financial benefit. Not every discrepancy is worth contesting, especially if the potential saving is limited or the evidence is marginal. A commercially focused review should weigh the cost, effort and likely outcome rather than treat every query as a case to push at all costs.
When professional advice makes the biggest difference
The more complex the property, the more important expert review becomes. Large premises, specialist buildings, mixed-use properties and multi-site portfolios often need more than a quick comparison with neighbouring assessments. Even standard offices, shops and warehouses can produce avoidable overpayments if no one checks the detail.
For occupiers who want confidence that they are paying the right amount, specialist advisers bring more than process knowledge. They bring valuation judgement, evidence analysis and practical experience of what tends to succeed. Firms such as Get Your Rates Right.com support businesses by reviewing assessments, identifying whether a challenge is justified and handling the case professionally where it is.
If you are asking, is my rateable value correct, that question is already doing useful work. It means you are looking at business rates as a controllable cost rather than an unavoidable one. The right next step is not to guess, but to get the assessment tested properly so you can move forward with confidence.
