The latest government data on business rate appeals contains good news and bad news. On the downside, there has been a surge in the number of businesses launching cases: almost 130,000 business owners began the process during the first three months of the year, five times more than in the fourth quarter of 2025; that will probably lead to delays in processing claims. More positively, the data also shows that 57% of firms challenging their business rates bills eventually secured a reduction; in other words, your chances of winning are pretty good.
The statistics, published by the Valuation Office Agency (VOA) at the end of May, underline the importance of checking your business rates assessment quickly. New assessments of the rateable value of more than two million business properties in England and Wales came into force on 1 April; this rateable value, based on the VOA's estimate of the commercial rent potentially chargeable on each property, is what determines your business rates bill.
It's now too late to appeal business rates set following the previous VOA revaluation, which took place in 2023; the deadline was 31 March, which is part of the reason for the spike in claims in the first quarter. But you can challenge the rateable value that came into force in April. If you can show the VOA is overestimating how much rent your business property could secure – either what you are paying to rent it, or if you own the property how much you could rent it out for – you could get a reduction.

Check, challenge and appeal your business rates
Such cases involve three stages. Step one is known as a “Check”. Effectively, you're just asking the VOA to confirm the factual details it holds about your property, so you can check you're not being overcharged because of inaccurate data. Relatively few Checks result in a reduction, so most businesses then move on to stage two, known as “Challenge”.
Following a Check, you have four months to submit a Challenge. This is your opportunity to present evidence suggesting your rateable value has been wrongly estimated. That could include, for example, details of the open-market rent agreed on the property, or details of other leases on similar properties nearby. Alternatively, there may have been a material change to your property – you're using it for a different purpose, say, or there have been developments in the area that could affect its value.
Cases that don't succeed at the Challenge stage can be appealed at the independent Valuation Tribunal Service. There's a fee of up to £300 to launch an Appeal – stage three of the process – and you must file your claim within four months of receiving the Challenge decision. You'll get your fee back if you win.
In theory, you can handle each stage of a business rates case yourself, but many businesses appoint a professional agent to manage the process on your behalf – particularly if they proceed to Appeal. Agents can give you advice on whether it's worth bringing your case and handle the work for you, using their experience to maximise your chances of success.
Make sure you appoint a reputable agent. The Royal Institution of Chartered Surveyors can provide details of firms that abide by their professional standards and code of best practice.
Finally, it's important to note these processes can result in your business rates bill rising rather than falling. This is relatively unusual, but certainly not unheard of. Make sure you're not presenting evidence that gives the VOA reason to think it has underestimated your rateable value.
