More than five thousand small business owners have put their names to an open letter warning the chancellor that the looming business rates revaluation could be the blow that finishes them off.
The letter, signed by 5,500 firms and sent directly to Rachel Reeves, calls on the Treasury to reassess the impact of the revaluation due to take effect on 1 April and introduce meaningful relief measures before it is too late. The language is unusually stark for a business lobbying exercise. Several signatories describe the changes as nothing short of apocalyptic.
Their argument is straightforward: small businesses operating from premises on high streets and in town centres have already absorbed years of compounding cost increases. Rising rents, soaring energy bills, higher insurance premiums, inflation, staffing pressures, Covid-era debt that has never fully been repaid, and successive tax increases have each taken their toll. Many owners say they have cut their own wages, borrowed to stay afloat and worked punishing hours simply to keep the doors open.
Now, with the 2026 revaluation recalculating rateable values to reflect current market conditions, a significant number of small businesses in areas where property values have risen face sharp increases in their rates bills, in some cases by thousands of pounds a year. For a small independent retailer or café already operating on thin margins, the sums simply do not add up.
The concern is particularly acute outside London, where the revaluation is expected to shift a greater share of the overall rates burden onto smaller commercial properties in towns that have seen modest property price growth. Meanwhile, some larger retailers in high-value locations may actually see their bills fall or remain stable, a perverse outcome that the letter’s signatories say makes the system fundamentally unfair.
The government has pointed to transitional relief arrangements designed to phase in the sharpest increases over several years, but business groups argue that these measures are insufficient for the smallest firms. A phased increase is still an increase, and for a business already running at or near its overdraft limit, even a modest annual rise can tip the balance from survival to closure.
What the signatories want is a proper review of business rates for small firms, not tinkering with transitional relief but a structural reassessment of how the system treats the kind of independent, premises-based businesses that give high streets their character and employ local people.
Whether the Treasury listens is another matter. Business rates generate roughly £25 billion a year for local government, and no chancellor willingly gives up revenue on that scale. But the political cost of presiding over a wave of high street closures is not negligible either, and with local elections in sight, the letter may carry more weight than its authors expect.
