Why Are Premises Rates Incorrect? Key Causes

A rates bill can look fixed and official, so it is easy to assume the figure must be right. But if you are asking, “why are premises rates incorrect?”, the answer often lies in the Rateable Value used to calculate your bill. That value is an informed assessment, not a guaranteed reflection of every detail of your premises, its condition or the market around it.

For a shop, office, surgery, pub, warehouse or factory, an incorrect valuation can mean paying more than you should year after year. The potential cost is not just the current demand. It can affect cash flow, budgeting and, where a successful challenge is possible, historic overpayments too. The good news is that a business rates assessment can be reviewed. You do not have to accept it without question.

What your premises rates are actually based on

Business rates are charged by your local authority, but the Rateable Value usually comes from the Valuation Office Agency (VOA). Broadly, the Rateable Value is intended to represent the annual rent your property could have achieved at a legally specified valuation date, using statutory assumptions.

Your bill is then produced by applying the relevant business rates multiplier and any reliefs or adjustments. This means an unexpectedly high bill may stem from more than one issue. The Rateable Value could be too high, the property details could be inaccurate, or you may not be receiving a relief for which you qualify.

A lower rent on your own lease is not automatically proof that the valuation is wrong. Equally, a high Rateable Value is not automatically correct simply because it has appeared on a formal document. Rating is evidence-led and highly property-specific. The question is whether the assessment properly reflects the statutory basis and the facts of your occupation.

Why are premises rates incorrect in the first place?

The VOA values a huge number of commercial properties. Valuers use rental evidence, property information, valuation schemes and market analysis to reach assessments at scale. That process is necessary, but it can leave room for an assessment that does not fully capture a particular building or local trading position.

The property record may be wrong

Start with the basics. The recorded floor area, use, layout, age or physical description may not match the premises you occupy. A valuation based on more usable space than you actually have can plainly distort the result. So can a description that treats storage, ancillary rooms or poor-quality accommodation as though it were prime operational space.

Mixed-use properties need particular care. A building with a retail frontage, first-floor offices, storage and unused space should not necessarily be valued as one uniform area. The value attached to each part can matter significantly.

Your premises may have physical disadvantages

Condition and usability are not the same thing. Water ingress, persistent damp, structural restrictions, low headroom, an awkward layout, inadequate loading access or a lack of customer parking can all affect how a property performs in the market.

Not every defect will justify a reduction. Minor wear and tear or a temporary inconvenience may have little rating impact. However, a material issue that affects occupation, rental value or the practical use of space may need to be considered. Evidence is crucial here: photographs, reports, plans, correspondence and a clear record of when the problem arose can all help establish the facts.

Local circumstances may have changed

Sometimes the property itself is sound, but its surroundings have changed for the worse. Long-running roadworks, restricted access, nearby redevelopment, loss of parking, changes to pedestrian flows or disruption from construction can have a real effect on a business premises.

The timing matters. A short period of disruption may not produce the same outcome as a prolonged issue that makes the property less accessible or less attractive to occupiers. In some cases, a change in circumstances can support an alteration to the rating assessment from the relevant date. That is why delaying a review can be costly.

The valuation may not reflect the right rental evidence

Business rates valuations are not simply copied from your lease. Valuers consider comparable rental transactions and apply rating principles to reach a fair figure. The challenge is that comparable evidence is only useful when it is genuinely comparable.

A modern, well-positioned unit with strong access may not be a fair match for an older premises in a secondary location. A warehouse with a large secure yard may command a different value from one with constrained servicing. Local knowledge matters because small differences between roads, estates and town-centre pitches can make a substantial difference to rental tone.

The assessment may overlook an exceptional feature

Some features are not obvious from a database entry or external inspection. A dental surgery may have unusable rooms because of layout limitations. A retailer may have a severely restricted frontage. A factory may have outdated services or limited vehicle turning space. An office could be burdened by a configuration that makes part of the floorplate difficult to let or use.

These are not excuses to avoid a rates bill. They are commercial facts which may influence the correct valuation when properly evidenced and applied within the rating rules.

A high bill is not always an incorrect bill

It is tempting to compare your rates bill with a nearby occupier’s and assume yours must be wrong. That comparison can be a useful prompt for a review, but it is rarely the whole story. Different areas, uses, fit-outs, lease evidence, reliefs and valuation dates can lead to different outcomes.

Likewise, a drop in trade does not automatically mean a Rateable Value should fall. Business rates generally assess the property rather than the profitability of the occupier. There are exceptions and sector-specific considerations, but a sound challenge needs to focus on the rating basis, not simply the pressure on a business’s bottom line.

That is where professional judgement earns its place. A good review separates a genuine valuation issue from a case that is unlikely to succeed, saving you from wasting time on a claim with no realistic foundation.

Signs your Rateable Value deserves a review

There is no need to become a rating expert before seeking help. If your premises have changed, your property details look wrong, or your bill appears out of step with the building you occupy, it is sensible to investigate.

Pay particular attention if you have taken on premises with defects, lost access or parking, experienced extended external works, altered the layout, or discovered that areas recorded for rating are not usable as described. Businesses that have never checked their assessment should also consider a review. An error can remain unnoticed simply because the bill has been paid each year.

Do not confuse a rates valuation review with asking the council for a discretionary discount. They are different routes. One concerns whether the Rateable Value is correct; the other may concern reliefs, payment arrangements or local policy. It may be appropriate to examine both, but they require different evidence and processes.

What a proper business rates review involves

A credible challenge is not a form-filling exercise. It begins with checking the rating list entry and understanding the property. A specialist then considers the valuation approach, relevant rental evidence, physical features, local circumstances and the procedural route available through the VOA.

Evidence gathering can include measured areas, photographs, plans, lease information, condition reports and market comparables. The stronger and more relevant the evidence, the better the chance of presenting a clear case. There is no guarantee of a reduction, and some cases will not justify an appeal. But an informed assessment gives you a far better basis for action than a guess based on the size of the bill.

There are also deadlines and rules around proposals, supporting information and the point from which any change may take effect. Getting the detail wrong can limit the outcome. Busy directors and finance teams should not have to learn a technical statutory system while running their operation.

At Your Local Business Rates Saver, RICS or IRRV-qualified surveyors can assess whether there is a viable case, handle the evidence and manage the appeal process on your behalf. The initial eligibility review is free, so you can establish whether savings may be available before committing your own time to a complex process.

Act while the evidence is still available

If your premises have been affected by poor condition, access restrictions or changes in the local area, record what is happening now. Keep dated photographs, contractor reports, landlord correspondence and details of disruption. These records can become much harder to obtain months later, particularly after works have finished or staff have moved on.

The same principle applies to leases and floor plans. A small factual error can be easier to resolve when the documents are to hand and the people who know the premises can explain how it is used.

Your rates bill is a significant operating cost, not a figure to file away without scrutiny. If the valuation does not reflect the reality of your premises, a timely expert review could be the first practical step towards protecting your cash flow and paying no more than the rules require.
