How to Spot Rating Errors on Your Business Rates Bill

A business rates bill can look final, technical and not worth challenging when you have customers to serve and a business to run. But knowing how to spot rating errors could reveal that your premises are being assessed on the wrong facts – and that you are paying more than you should.

The key figure to question is usually the Rateable Value. This is the Valuation Office Agency’s assessment of the annual rental value of your commercial property at a fixed valuation date. Your council then uses it, alongside the relevant multiplier and any reliefs, to calculate your bill. If the Rateable Value is too high, the cost can follow you year after year.

Start with the Rateable Value, not just the total bill

A higher bill does not automatically mean there is a rating error. Annual charges can rise because the business rates multiplier has changed, transitional arrangements have applied, or a relief has ended. Those are billing and policy issues rather than proof that the property valuation is wrong.

However, your Rateable Value may deserve a closer look if it does not reflect the property you actually occupy, the space you use, or the local market conditions affecting it. This is particularly relevant for shops, offices, pubs, dental surgeries, warehouses and factories, where small factual differences can have a meaningful impact on the assessment.

Find the Rateable Value shown on your council bill and compare it with the VOA’s rating record for the property. The figures should broadly correspond. Then move beyond the headline number: the real question is whether the facts and valuation basis behind it are accurate.

How to spot rating errors in your property record

You do not need to become a rating surveyor to recognise a potential problem. Think of this as a practical first check. If one or more of the following points apply, it may be worth asking for a professional review.

1. The floor area is too large

An overstated area is one of the clearest reasons for an inflated Rateable Value. Check whether the record includes storage, corridors, mezzanines, offices, yards or ancillary areas that you do not occupy or cannot use as described. Measurements should also reflect the appropriate rating basis, not simply a figure copied from an old lease or sales particulars.

This can matter in a warehouse with a large low-value storage section just as much as in a town-centre shop where retail frontage carries a premium. A few wrongly measured square metres may not sound dramatic, but the annual cost can soon add up.

2. The description of the premises is wrong

The VOA record may show the wrong property type or assume a use that no longer applies. A former restaurant may now operate as a lower-value retail unit. A first-floor office may be recorded as though it benefits from ground-floor visibility. A unit with limited access may be compared with premises that have prominent frontage and customer parking.

The description does not have to be wildly wrong to affect value. Details such as floor level, layout, loading access, ceiling height and the quality of customer access can all influence how comparable properties are assessed.

3. A material disadvantage has been missed

Some properties have genuine drawbacks that affect their rental value. Persistent flooding risk, poor loading arrangements, restricted access, awkward layout, structural issues, roadworks, loss of parking or nearby construction can all be relevant, depending on the circumstances and timing.

Not every inconvenience leads to a reduction. The issue must be material and supported by evidence, and the rating rules can be technical. Still, if your trading or use of the property is clearly affected by something the assessment appears to ignore, do not assume it has already been taken into account.

4. You are compared with better premises

Rating valuations are built from rental evidence and comparable properties. The difficulty is that two units with the same headline size can have very different appeal to occupiers. A modern industrial unit with a secure yard, strong eaves height and easy HGV access is not equivalent to an older building with a constrained entrance and limited loading space.

Likewise, a retail unit on a busy pitch should not be treated the same as one hidden behind a service road or affected by a declining footfall location. This is where local market knowledge and proper valuation analysis make a difference. The question is not whether another property has a similar Rateable Value, but whether it is genuinely comparable.

5. Alterations, demolition or vacant areas are not reflected

Has part of the building been removed, made unusable or taken out of occupation? Have you lost a section of floor space following works, fire damage or a change in layout? Is an extension shown before it was complete, or is a demolished element still included?

Keep records of dates, plans, photographs and contractor correspondence. Timing matters in business rates, so an otherwise valid issue can be harder to pursue if the evidence does not clearly show when the change occurred.

6. Reliefs or exemptions are absent from the bill

This is not always a Rateable Value error, but it is still an expensive rating mistake. Depending on your circumstances, you may qualify for Small Business Rate Relief, charitable relief, empty property relief, rural rate relief or another form of support. Some reliefs require an application and may not appear automatically.

Check the bill for the reliefs shown and compare them with your current occupation and property use. A correct Rateable Value can still produce an unnecessarily high charge if the council has not applied a relief you are entitled to receive.

Gather facts before making assumptions

A useful rating review starts with evidence, not guesswork. Put your latest business rates bill alongside your lease, floor plans, site plan and any previous valuation correspondence. Photographs can help demonstrate access restrictions, disrepair or changes to the building. If you have details of nearby lettings, keep them, but remember that one rent figure rarely tells the whole story.

It is also worth recording what has changed since you moved in. Note dates for alterations, loss of space, road closures, construction works and changes to access. The more clearly you can set out the facts, the easier it is for a surveyor to identify whether there is a credible case.

Do not rely solely on your rent as proof that the Rateable Value is too high. Rent is relevant, but lease incentives, repair obligations, fit-out, lease length and market conditions all need to be considered. Rating valuation is evidence-led, and a strong case needs more than the feeling that the bill is unfair.

When a high bill is not a rating error

Some bills are correct even when they are difficult to absorb. A revaluation can change assessments across an area, while the multiplier can increase the final charge without any change to your property details. Rate relief may also have ended because your circumstances changed.

There are also occasions where a neighbouring occupier pays less for understandable reasons. They may have a smaller assessed area, a different use, an earlier alteration date, a separate relief or a property with materially different characteristics. This is why comparing bills alone can mislead.

The right approach is to test the assessment against the evidence for your own premises. If the facts support the VOA’s valuation, you have clarity. If they do not, you have a reason to act.

What to do if you think your rating is wrong

Start by checking the property record and retaining copies of anything that looks inaccurate. Avoid altering information casually or submitting a challenge before the position has been properly assessed. The process for questioning a valuation has formal stages, deadlines and evidence requirements, and a weak or poorly timed submission can create unnecessary delays.

A qualified rating surveyor can assess the valuation, inspect the relevant evidence and advise whether an appeal is likely to be worthwhile. They can also handle communication with the VOA and help distinguish between a valuation issue, a billing issue and a relief claim. Your Local Business Rates Saver offers a free initial eligibility review, so you can establish whether savings may be available before committing time to a technical process.

If a successful case supports a lower assessment, it may reduce future liabilities and, where the rules and dates allow, lead to a refund for historic overpayments. Outcomes depend on the facts of the property and the available evidence, so no reputable adviser should promise a reduction before reviewing the case.

Your business rates are too significant to treat as a fixed overhead without question. Check the facts behind the figure, keep evidence of anything that has changed, and ask for expert help when the valuation does not look right.
