If you’re renting a commercial space in the UK, the figure that quietly determines a huge chunk of your overheads is your property’s rateable value. It’s not your rent, and it’s not your final bill, but it’s the number the council uses to calculate how much you pay in business rates. The Valuation Office Agency (VOA) updates these values every three years, and the latest revaluation took effect on 1 April 2026, based on rental market conditions from 1 April 2024. That means the rateable value on your bill right now reflects what the market looked like two years ago, not today. Understanding this number — and whether it’s accurate — is one of the most practical things you can do to keep your business costs under control.
I’ve been writing about commercial property costs for a while now, and the one thing that comes up again and again is confusion around this single metric. Tenants see a big number on their bill and assume it’s fixed, or they assume it’s wrong but don’t know how to push back. The truth is, rateable values are based on a specific methodology, and they can be challenged — but only if you follow the right process. Here’s what you actually need to know.
Before you sign a lease, it’s worth checking the rateable value of the property you’re looking at. It can make the difference between a manageable monthly outlay and a nasty surprise. If you’re comparing spaces, you might also want to read up on understanding square footage when renting commercial space, because the size of the property directly feeds into how the VOA calculates its value.
What Rateable Value Actually Means for Your Business
Here’s the most important thing to understand: your rateable value is not what you pay. It’s the starting point. Local councils take that figure, apply a standard percentage called the multiplier, and then subtract any reliefs or discounts you qualify for. The result is your business rates bill. So a change in your rateable value doesn’t always mean a change in your bill — other factors like transitional relief can cushion the impact.
The VOA uses one of three methods to arrive at this figure. For most shops and offices, they analyse the rental market to find comparable properties. For properties where rental evidence is thin — like large hotels or cinemas — they look at trading information to estimate a reasonable rent. And for specialist properties like hospitals, they may consider the yearly cost of a replacement building. The key point is that your rateable value may not match the actual rent you’re paying. That’s normal. What matters is whether the VOA’s estimate is fair and accurate for your specific property.
If I were looking at a new commercial space, my first move would be to check the rateable value before signing anything. You can do that through the find a business rates valuation tool on GOV.UK. It’s free, it takes five minutes, and it gives you a number that could save you hundreds or thousands of pounds a year if it’s wrong.
Why the 2026 Revaluation Matters Right Now
The 2026 revaluation came into effect on 1 April 2026, and it’s based on rental values from April 2021 to April 2024. That period saw some dramatic shifts in the commercial property market. High street retail took a hit, while industrial and logistics spaces boomed. Offices in some cities saw rents fall, while others held steady or rose. The whole point of a revaluation is to redistribute the tax burden so that businesses in areas with falling rents pay less, and those in areas with rising rents pay more.
What this means for you depends entirely on your sector and location. If you run a shop on a high street where rents have dropped, your rateable value should ideally reflect that. If you’re in a logistics unit where demand has surged, you might see an increase. The VOA’s own guidance says that a change in your rateable value does not always mean a change in your bill, but it’s still worth understanding where you stand.
Let me give you a realistic scenario. Imagine you run a small café in a town centre where foot traffic has declined since 2021. Your rent has stayed flat, but the VOA’s valuation might still be based on older, higher rents from before the downturn. If that’s the case, you could be paying more in business rates than you should be. On the flip side, if you’ve expanded your premises and the VOA hasn’t updated its records, your rateable value might be too low — and a challenge could actually increase it.
What I tend to notice is that tenants rarely check their rateable value until they get a bill that feels too high. By then, the window for challenging the current valuation may have narrowed. You have until 31 March 2026 to contact the VOA about your current rateable value, and from 1 April 2026 you can challenge the new one. Don’t wait until the bill arrives.
Where Tenants Get Tripped Up
I’ve seen the same mistakes crop up again and again. Here are the most common ones, and how to avoid them.
Mistaking rateable value for the final bill
This is the biggest one. Tenants see a rateable value of, say, £25,000 and assume they’ll pay £25,000 in business rates. In reality, the multiplier — set by the government each year — is applied to that figure. For 2026/27, the standard multiplier is around 51p per pound of rateable value, meaning a £25,000 rateable value would produce a bill of roughly £12,750 before any reliefs. Small business rates relief can reduce that further, sometimes to zero. Always check what reliefs you qualify for before panicking about the headline number.
Assuming the VOA’s valuation is correct
The VOA does its best, but it works with broad data. Your property might have unique features — a awkward layout, poor access, or structural issues — that make it less valuable than similar properties in the area. If you think the valuation is wrong, you can challenge it. The process is called Check, Challenge, Appeal. First, you raise a “check” case through your business rates valuation account to correct factual details. If that doesn’t change the value, you can progress to a “challenge” where you provide evidence. Be aware: your rateable value can go up as well as down during this process, so only challenge if you have solid evidence.
Falling for rogue rating agents
The VOA itself warns that a small minority of rating agents act in bad faith. These rogue agents promise huge reductions in business rates, but they do it by submitting inaccurate information. If the VOA catches it, you could face penalties or a higher bill. If you decide to use an agent, choose one with a solid reputation. The vast majority are reputable, but it’s worth doing your homework. You can also manage the process yourself — it’s not as complicated as it sounds.
Ignoring the valuation date
Your rateable value is based on what the property could have rented for on 1 April 2024. If you moved in after that date, or if the local market has changed significantly, the valuation might not reflect your reality. This is especially relevant for new-build properties or spaces that have been recently refurbished. The VOA may not have up-to-date information on your property’s condition, which could mean the valuation is too high.
If you’re dealing with a complex property or a dispute that feels beyond your comfort zone, it might be worth speaking to a real estate lawyer who can help you navigate the Check, Challenge, Appeal process. They’ll know what evidence the VOA expects and how to present your case effectively.
| Step | What you do | Time limit |
|---|---|---|
| Check | Correct factual details about your property via your VOA account | Until 31 March 2026 for current valuation |
| Challenge | Provide evidence if the check doesn’t change the value | After check is resolved |
| Appeal | Take your case to a tribunal if the challenge is rejected | Within 4 months of challenge decision |

If you think your rateable value is wrong, here’s exactly what to do. The process is straightforward, but you need to follow the steps in order.
Find your current rateable value
Start by looking up your property on the find a business rates valuation tool on GOV.UK. You don’t need an account for this — just enter your postcode or property address. The tool will show you your current rateable value and let you compare it to similar properties in the area. If you want more detail, you’ll need to create a business rates valuation account. This lets you see how the VOA calculated your value and check the property details they hold.
Raise a check case
If you spot an error — like the wrong floor area, incorrect property type, or missing information about a recent refurbishment — you can raise a check case through your account. This is the first step in the formal process. You tell the VOA what’s wrong and provide evidence. They’ll review it and either correct the valuation or explain why they think it’s right. You can only raise a check case for a previous valuation in limited circumstances, such as if the VOA corrected your valuation in the past six months, or if you want to challenge a 2023 valuation after a tribunal decision — in which case you must act within six months of that decision.
Progress to a challenge
If the check doesn’t result in a change, you can move to a challenge. This is where you present your evidence more formally. You’ll need to show why the VOA’s valuation is wrong — for example, by providing rental evidence from comparable properties, or a surveyor’s report on your property’s condition. The VOA will review your evidence and make a decision. Remember, your rateable value can go up as well as down, so only challenge if you’re confident in your evidence.
Appeal if necessary
If the challenge is rejected, you can appeal to a tribunal. This is a more formal process and usually requires professional help. Most disputes are resolved at the check or challenge stage, so don’t let the possibility of an appeal put you off starting the process.
If you’re planning to challenge your valuation, it’s a good idea to have a clear record of your property’s condition and any relevant correspondence. A carbon monoxide alarm might seem unrelated, but if your property has a known safety issue that affects its rental value, documenting it can strengthen your case. More broadly, keeping a file of everything related to your property — from lease agreements to maintenance records — will make the process much smoother.
What to do if you’re a new tenant
If you’ve just taken on a commercial lease, check the rateable value as soon as you move in. The VOA may not have updated its records to reflect changes in the property, and you don’t want to overpay for months before you notice. You can also check whether the previous tenant had any reliefs or discounts that you might be able to carry over. This is one of those areas where a bit of upfront effort can save you a lot of money down the line.
