The business rates revaluation that took effect this year has landed on small business owners the way it always does, quietly, confusingly, and usually with a rateable value that seems to have nothing to do with reality. If you rent an office, a workshop, a studio or any kind of commercial premises, you have probably already had the letter. If you have not opened it yet, you might want to sit down first.
I have run businesses with physical premises and businesses without them, and the difference in how much mental energy business rates consume is enormous. This year's revaluation is a good moment to talk about why the system is still broken, who it actually hurts, and what small business owners can do about it right now rather than just accepting the number on the letter.
What the 2026 revaluation actually changed
Business rates are supposed to be reassessed periodically so that what you pay reflects current property values rather than numbers from years ago. The 2026 revaluation is based on rental values from 2024, which sounds sensible in theory. In practice it means a huge number of small premises have jumped in rateable value even though the business inside them has not grown at all.
Retail units in busy areas, small offices in cities that have seen rent increases, and workshop or studio space in regenerated areas have all seen rateable values move, often upward. Meanwhile the actual profitability of the businesses occupying those spaces has, in a lot of cases, gone nowhere near as far. The rates bill is chasing property market movement, not business performance, and that mismatch is exactly the problem.
The relief system has not caught up
Small Business Rate Relief still works on thresholds that feel like they were set for a different economy. Full relief for the smallest premises, tapering relief as rateable value climbs, and then a fairly hard drop off once you cross into the next bracket. I have spoken to business owners who have deliberately avoided taking on slightly bigger premises because it would tip them over a relief threshold and cost them thousands of pounds a year for what amounts to a few extra square metres.
That is the same broken incentive structure you see everywhere else in UK small business policy. The VAT threshold does it. Some employment thresholds do it. And business rates relief does it too. Instead of a smooth curve that scales with the size of the business, you get a cliff edge that punishes growth right at the moment a business is trying to take its next step.
Why I stopped renting office space altogether
When I was building my early businesses I rented small office space because that is just what you did. It felt like a milestone, proof you were a proper company. Looking back, a decent chunk of that spend was rates, service charges and admin that had nothing to do with building the product or serving customers.
By the time I was running CampSuite at any real scale, the calculation had changed completely. Cloud tools, remote first teams and better video conferencing meant a physical office was a cost centre with very little upside. No rates, no business rates appeals, no argument with the Valuation Office about whether a mezzanine floor counts as usable space. Just a team working from wherever suited them, and a lot more of the budget going into the product.
I am not saying every business should go fully remote. Plenty of businesses genuinely need premises, whether that is a workshop, a client facing office or retail space. But if you are a small tech business weighing up whether an office is worth it, put the true cost of business rates into that decision honestly. It is often bigger than people expect, and it rarely buys you anything your customers actually care about.
The appeals process is not built for small businesses
If you think your new rateable value is wrong, you can challenge it through the Check, Challenge, Appeal process. In theory this exists to correct mistakes. In practice it is slow, bureaucratic and heavily weighted toward businesses that can afford a rating surveyor to fight their corner.
A large retailer or a national chain has a team whose entire job is managing rates appeals across hundreds of properties. A small business with one shop or one office has an owner who is also doing the sales, the accounts and probably the cleaning, trying to work out how to challenge a valuation methodology that is not explained anywhere in plain English. The system assumes a level of resource that most small businesses simply do not have.
If you are challenging a valuation this year, get your evidence together early. Comparable rents for similar premises nearby, evidence of any disrepair or restricted use, and a clear written case rather than a vague complaint that the number feels too high. Vague complaints get ignored. Specific, well evidenced ones at least get read properly.
What would actually fix this
None of this is unfixable. A rates system that scaled smoothly with rateable value instead of using hard thresholds would remove the perverse incentive to stay artificially small. A genuinely simple online appeals process, with clear guidance and realistic timescales, would let small business owners challenge unfair valuations without needing to hire a specialist. And more frequent, smaller revaluations would stop the shock of a single big jump every few years.
None of that is technically difficult. The data exists. The technology exists. What is missing is the political will to prioritise a system that mostly affects small businesses who do not have a powerful lobby shouting on their behalf. I have written before about how UK small business policy keeps failing entrepreneurs, and business rates are a textbook example of the same pattern. Good intentions, outdated mechanics, and a burden that lands hardest on the businesses least equipped to absorb it.
What to actually do about it
If you have physical premises, check your new rateable value on the government's valuation list as soon as you can, do not wait for the bill to force the issue. Work out whether you qualify for small business rate relief and make sure you are actually claiming it, because it is not always applied automatically. And if the number looks wrong, start gathering evidence now rather than after the challenge window has narrowed.
If you do not have physical premises yet and are weighing up whether to take some on, factor the true, ongoing cost of business rates into your numbers honestly before you sign anything. It is one of those costs that is easy to underestimate until the first revaluation letter lands on your desk.
I talk through exactly this kind of practical business decision making in my book, The 28 Day Startup, because getting the fundamentals right early saves you from expensive surprises later. And if you want to talk through your own situation, whether that is premises, growth planning or just making sense of the numbers, my consulting services exist for exactly that conversation.
