The UK’s inflation rate surged to 3.5% in April 2025, according to the latest data from the Office for National Statistics (ONS), marking the highest level since January 2024. This sharp rise from March’s 2.6% has exceeded expectations and sparked renewed concerns about the trajectory of the UK economy under Chancellor Rachel Reeves’ fiscal policies and the government’s broader economic strategy. Below, we unpack the actual figures against prior data and forecasts, identify the key drivers of this inflationary spike, and explore its implications for the economy and interest rates, with a critical lens on the role of net zero policies and Reeves’ budget.
Inflation Figures: Actual vs. Previous vs. Expectations
The Consumer Price Index (CPI) inflation rate for April 2025 rose to 3.5%, up significantly from 2.6% in March, as reported by the ONS. Core CPI, which excludes volatile items like food and energy, climbed to 3.8%, while services inflation hit a striking 5.4%, underscoring persistent price pressures in key sectors. A poll of City economists had forecasted a more modest increase to 3.3%, with the Bank of England (BoE) anticipating 3.4%. The actual figure of 3.5% thus overshot both analyst and central bank expectations, signalling that inflationary pressures are intensifying beyond what was anticipated.
Looking ahead, the Office for Budget Responsibility (OBR) projects inflation to peak at 3.8% in July 2025, driven by higher energy and food prices and sustained wage growth, before gradually declining to 2.1% by 2026. This trajectory suggests that the current spike is not a one-off but part of a broader inflationary trend that could challenge the BoE’s 2% target for some time.
Drivers of the Inflation Surge
Several factors have converged to push inflation higher, with policy decisions playing a central role:
- Energy Costs: A significant driver of the April increase was a 6.4% rise in the energy price cap effective from April 1, 2025, which has directly increased household bills. This follows a £279 rise in the energy cap since July 2024, squeezing consumers and businesses alike. The government’s aggressive net zero policies, including heavy subsidies for renewable energy and carbon pricing mechanisms, have contributed to elevated energy costs. These policies, while aimed at reducing emissions, have placed upward pressure on prices by increasing reliance on less stable and often more expensive renewable energy sources, particularly as global fossil fuel prices remain volatile.
- Minimum Wage Increase: The National Living Wage saw a substantial hike in April 2025, a move championed by the Labour government to support low-income workers. However, this increase has raised labour costs for businesses, particularly in sectors like retail and hospitality, which employ large numbers of minimum-wage workers. These costs are often passed on to consumers, contributing to the 5.4% services inflation rate and fuelling broader price pressures.
- National Insurance (NI) Contributions: Chancellor Rachel Reeves’ October 2024 budget introduced significant increases in employer National Insurance contributions, a policy that has been widely criticised for its stagflationary impact. The NI hike has raised operational costs for businesses, prompting many to increase prices to maintain margins. This tax increase, combined with the minimum wage rise, has created a double burden for employers, amplifying inflationary pressures across the economy.
- Other Factors: Additional price hikes in water, broadband, and council taxes, which took effect in April, have further strained household budgets, contributing to the overall inflation surge. Persistent wage growth, driven by a tight labour market, has also kept services inflation elevated, as firms compete for workers in a high-cost environment.
Economic Implications
The jump in inflation to 3.5% has significant implications for the UK economy, which is already grappling with sluggish growth and fiscal challenges. The OBR recently downgraded its 2025 growth forecast to 1%, reflecting concerns about higher interest rates, energy price expectations, and declining consumer and business confidence. The combination of rising inflation and modest growth points to a risk of stagflation—a scenario where stagnant economic output coexists with persistent price increases.
For consumers, the inflation surge translates to a higher cost of living, with household bills—particularly energy—eating into disposable incomes. This could dampen consumer spending, a key driver of economic growth, and exacerbate financial pressures for lower- and middle-income households. Businesses, meanwhile, face squeezed margins due to higher labour and energy costs, which could lead to reduced investment and hiring, further slowing economic activity.
Impact on Interest Rates
The inflation spike poses a significant challenge for the Bank of England’s Monetary Policy Committee (MPC). With inflation now well above the 2% target and services inflation at 5.4%, the BoE’s credibility is under scrutiny. Posts on X reflect growing scepticism about the central bank’s ability to manage inflation without tightening policy further. The MPC had previously signalled a cautious approach to rate cuts, with the base rate steady at 4.75% as of May 2025. However, the higher-than-expected inflation figures may force the BoE to reconsider its stance.
Economists now expect the BoE to delay any rate cuts until at least late 2025, with some even suggesting the possibility of a rate hike if inflation continues to climb toward the OBR’s projected 3.8% peak in July. Higher interest rates would increase borrowing costs for consumers and businesses, potentially stifling investment and housing market activity, but they may be necessary to curb runaway inflation. The BoE’s February 2025 projections, which extend through September, will be critical in shaping expectations for monetary policy.
The Role of Net Zero Policies and Reeves’ Budget
Critics, including voices on X, have pointed to the government’s net zero agenda and Chancellor Reeves’ October 2024 budget as key culprits in the inflation surge. The push for net zero, while environmentally ambitious, has driven up energy costs through subsidies for renewables and carbon taxes, which disproportionately burden households and businesses. These policies have failed to deliver affordable energy, leaving the UK vulnerable to global energy price shocks and domestic supply constraints.
Reeves’ budget, meanwhile, has been widely panned for its stagflationary effects. The increase in employer NI contributions and the minimum wage hike, while framed as progressive measures, have raised business costs at a time when firms are already grappling with high energy prices and post-Brexit trade frictions. Posts on X, such as those from

and @CityAM highlight the tax hikes and wage increases as direct contributors to the 3.5% inflation rate, accusing Labour of mismanaging the economy. The budget’s failure to provide meaningful relief for businesses or address energy cost drivers has eroded confidence, as evidenced by falling sentiment indicators cited by the OBR.
Conclusion
The UK’s inflation rate of 3.5% in April 2025, up from 2.6% in March and above expectations of 3.3%–3.4%, signals a troubling escalation of price pressures. Driven by rising energy costs, minimum wage increases, and higher National Insurance contributions, this surge reflects the unintended consequences of Labour’s fiscal and environmental policies. The economy faces the dual threat of slowing growth and persistent inflation, raising the spectre of stagflation. For the Bank of England, the path forward is fraught, with pressure mounting to maintain or even raise interest rates to tame inflation, at the risk of further choking growth.
Chancellor Rachel Reeves’ budget and the government’s net zero policies bear significant responsibility for this economic malaise. The NI hike and wage increases have burdened businesses, while the relentless focus on net zero has inflated energy costs without delivering affordable alternatives. As households and firms brace for higher costs and the BoE grapples with its next moves, the UK economy stands at a critical juncture, with Labour’s policy missteps casting a long shadow over its prospects.
