The Office for National Statistics has confirmed that the UK economy grew by 0.6% in the first quarter of 2026 — the fastest quarterly expansion in a year. Services were up 0.8%, production scraped 0.2%, construction managed 0.4%. The Chancellor's special advisers will be drafting triumphant tweets. The truth is colder: this is the best the British economy will look for the foreseeable future, because everything Labour has done since taking office is about to land on the same households at the same time.
What The 0.6% Actually Means
Strip out the cheerleading and Q1 growth was bought with three things: a mild winter, a one-off bounce in financial services, and the run-up to the April tax changes pulling consumer spending forward. None of those drivers repeat. The Bank of England's own forecast for Q2 is closer to flat. The OECD has downgraded its full-year UK forecast twice in three months. An economy growing at this rate is, in normal times, an economy on the edge of recession.
And these are not normal times. From April, dividend tax went up. Income tax thresholds remain frozen until 2031, so every pay rise drags more workers into higher bands. Council tax has gone up everywhere. Business rates relief has been cut. The agricultural inheritance tax change has begun to bite. The renters' rights changes have pushed landlords out of the market and rents up. Every single one of those measures pulls money out of households and small businesses, all at once.
The Iran Effect
On top of the domestic squeeze, the global picture is darkening. The conflict in the Gulf has pushed oil back above $90 a barrel. Shipping insurance premiums through the Strait of Hormuz are at their highest in a decade. Whatever growth Britain managed in Q1 was banked before the geopolitical bill arrived. CNBC's reading of the data was blunt: "the best is already behind it." That is not a forecast from a Reform UK pamphlet. That is the verdict of the international financial press.
The Productivity Truth
The deeper problem is that British productivity has barely moved in fifteen years. Per-worker output is still below the 2008 peak. We are getting less out of every hour we work than we did before the financial crisis. Tax rises do not fix that. Net-zero industrial policy does not fix that. A bloated welfare bill that pays people not to work does not fix that.
The only things that fix it are lower marginal tax rates, cheap reliable energy, sensible regulation, controlled immigration that doesn't suppress wages at the bottom, and a benefits system that makes work pay. Labour have moved in the opposite direction on every single one of those.
What Reform UK Would Do
Reform UK would unfreeze the income tax thresholds and raise the personal allowance to £20,000. We would scrap the windfall tax on North Sea production and end the war on domestic energy. We would cut corporation tax for small businesses, restore proper business rates relief on the high street, and reverse the agricultural inheritance tax raid that is killing family farms. We would end the net-zero subsidy regime that is loading hidden costs onto every household bill.
The Chancellor will spend the next month trying to take credit for 0.6%. The country will spend the next year discovering that 0.6% was the high water mark before her own tax rises pulled the tide back out. By the autumn statement we will be back to the same conversation we have had every year under Labour: weak growth, rising taxes, falling living standards, and a Treasury that refuses to admit any of it is connected to its own decisions.
