UK CPI Inflation: 2.8% in April and May 2026, Down from 3.3% inMarch — But Forecasters Warn of a Rise to Come
UK CPI inflation fell to 2.8% in the 12 months to April 2026, down from 3.3% in March, and heldat that level in May, according to the Office for National Statistics. The drop was largely driven bylower household energy bills, partially offset by rising motor fuel prices. Economists note the figureis also flattered by a base effect: prices in April 2025 were unusually high due to a cluster of billincreases that month, making year-on-year comparisons look smaller than they would otherwise.The respite is expected to be short-lived. Most economists forecast inflation will climb back toward4% by the end of 2026 as the economic fallout from the conflict involving Iran feeds through toenergy markets. The Bank of England’s own projection, based on energy market pricing in mid-April, put CPI at 3.1% in Q2, 3.3% in Q3, and rising further in Q4 due to higher energy and foodcosts. Before the conflict began, inflation had been expected to fall to around 2% from April andstay close to target for the rest of the year.Core inflation (excluding energy, food, alcohol and tobacco) eased to 2.5% in April before edgingup to 2.6% in May. Within that, the picture is mixed: goods inflation has been rising (from 2.1% to2.4%), while services inflation — which the Bank of England watches closely as a gauge ofdomestic price pressure — has been falling, down from 4.5% in March to 3.2% in April, beforeticking back up to 3.7% in May.On the household side, the Office for National Statistics’ wage data shows pay continuing tooutpace inflation only modestly. Retail sales volumes fell 1.3% month-on-month in April, reversinga 0.7% rise in March. Household debt stood at 117.5% of disposable income at the end of 2025 — aratio that has generally been falling since 2022, though it remains historically elevated.Key Facts:CPI inflation: 2.8% in the 12 months to April 2026 (down from 3.3% in March); unchangedat 2.8% in MayCPIH (includes housing costs): 3.0% in April and May 2026, down from 3.4% in MarchCore CPI (excl. energy, food, alcohol, tobacco): 2.5% in April, rising to 2.6% in MayServices inflation: fell from 4.5% (March) to 3.2% (April), then rose to 3.7% (May) —closely watched by the Bank of England as the more “domestic” inflation signalGoods inflation: rose from 2.1% to 2.4% between March and AprilMain driver of the April fall: lower household energy bills (electricity prices fell 8.4% y/y inApril)Forecast: Bank of England projects CPI at 3.1% (Q2), 3.3% (Q3), rising further in Q4 2026,driven by the Iran-conflict energy shockFood price inflation: 3.0% in April, easing to 2.2% in May — lowest since December 2024Retail sales: -1.3% month-on-month in April 2026 (vs +0.7% in March)Household debt: 117.5% of disposable income (Q4 2025), down from recent peaks but stillhistorically highPetrol prices: 157.4p/litre in May 2026 — highest since November 2022 Expert Insight (SWRR Centre): The headline drop to 2.8% is a useful reminder that single-month inflation readings can bemisleading without context. Part of the fall is a genuine response to lower energy bills, but part of itis a statistical base effect from an unusually high April 2025 — and the figure held flat rather thancontinuing to fall in May, with core and services measures actually ticking back up. Forecasters andthe Bank of England itself are already signalling that this is a pause rather than a trend, withinflation expected to approach 4% later in the year as the Iran-conflict energy shock works throughthe system.The divergence between goods and services inflation is also worth tracking. Services inflation isconsidered more persistent because it reflects domestic costs — wages, rents, and local pricingpower — rather than imported price shocks. Its renewed uptick in May, even as headline CPI heldsteady, suggests underlying domestic price pressure has not eased as much as the topline numberimplies.The retail sales fall and continued high household debt levels point to a consumer sector undersustained strain even before the next anticipated inflation rise. A household debt ratio of 117.5% ofdisposable income, even on a declining trend, leaves limited room for absorbing a further cost-of-living shock — a relevant data point for anyone assessing household resilience heading into aperiod of renewed price pressure.Sources:Office for National Statistics — “Consumer price inflation, UK: April 2026,” published May 2026Office for National Statistics — “Consumer price inflation, UK,” latest bulletin (May 2026 data)House of Commons Library — “Inflation in the UK: Economic indicators,” updated June 2026House of Commons Library — “Economic Indicators,” CBP-9040, published May 27, 2026
