UK CPI Report: May 2026 — Inflation Holds at 2.8% as Transport Surges, Food Eases
The Office for National Statistics (ONS) released the Consumer Price Index (CPI) report for May 2026 on June 17. Headline CPI held steady at 2.8% — unchanged from April and below the market consensus of 3.0% — as surging transport costs were offset by falling food prices.
Headline Overview
| Indicator | Apr 2026 | May 2026 | Change |
|---|
| CPI (YoY) | 2.8% | 2.8% | 0.0pp |
| CPIH (YoY) | 3.0% | 3.0% | 0.0pp |
| Core CPI (excl. food, energy, alcohol & tobacco) | 2.5% | 2.6% | +0.1pp 🔴 |
| CPI Services (YoY) | 3.2% | 3.7% | +0.5pp 🔴 |
| CPI Goods (YoY) | 2.4% | 2.0% | -0.4pp ⬇️ |
| CPI MoM | +0.7% | +0.2% | -0.5pp |
| RPI (YoY) | — | 3.1% | — |
Key takeaway: Headline CPI at 2.8% came in below both market expectations (3.0%) and the Bank of England's own Q2 projection. But the flat headline masks a concerning shift underneath: services inflation jumped from 3.2% to 3.7% and core CPI ticked up — two metrics the BoE watches more closely than the headline figure. The stability in the headline was due to food prices falling on the month, offsetting surging transport costs.
The broader CPIH (which includes owner occupiers' housing costs) also held at 3.0% for a second consecutive month.
Key Sector Inflation — CPI Divisions (Year-on-Year)
| Division | Apr 2026 | May 2026 | Change (pp) |
|---|
| Transport | 4.5% | 6.8% | +2.3 🔴 |
| — Motor Fuels | — | +24.6% | — |
| — Air Fares | — | ↑ (+10.3% MoM) | — |
| Food & Non-Alcoholic Beverages | 3.0% | 2.2% | -0.8 ⬇️ |
| Housing & Household Services (CPIH) | — | — | ⬇️ (OOH contribution smallest since Jun 2022) |
| Furniture & Household Equipment | — | -0.1% | ⬇️ (only negative sector) |
| Recreation & Culture | — | — | ⬇️ (downward contributor) |
| Restaurants & Hotels | — | — | ⬇️ (downward contributor) |
| Health | — | — | ⬇️ (downward contributor) |
🔴 Transport was the standout story — inflation hit 6.8% YoY, the highest since December 2022. Motor fuel prices surged 24.6% YoY, with average petrol reaching 157.4p per litre — the highest since November 2022. Air fares jumped 10.3% month-on-month, partly due to Easter timing: Easter fell in early April 2026, before the ONS pricing window opened, pushing more bookings into May's comparison.
🔴 Vehicle Excise Duty (VED) also added upward pressure via a base effect — a one-off correction that reduced the VED index last May is no longer in the comparison.
⬇️ Food provided the main counterweight, easing from 3.0% to 2.2% YoY — its lowest since December 2024 — and actually fell 0.1% month-on-month in May.
⬇️ Owner Occupiers' Housing (OOH) costs continued a remarkable 16-month consecutive decline in contribution, reaching just 0.57 percentage points — the smallest since June 2022, down from a peak of 1.31pp in January 2025.
Goods vs Services Split
| Measure | Mar 2026 | Apr 2026 | May 2026 |
|---|
| CPI All Goods | — | 2.4% | 2.0% ⬇️ |
| CPI All Services | — | 3.2% | 3.7% 🔴 |
| Core CPIH | 3.3% | 2.8% | 2.8% → |
| CPIH Goods | — | 2.4% | 2.0% ⬇️ |
| CPIH Services | — | 3.4% | 3.6% 🔴 |
⬇️ Goods deflation in real terms is accelerating — goods inflation slowed from 2.4% to 2.0%, suggesting tariff pass-through and import cost effects are fading.
🔴 Services inflation at 3.7% is the BoE's primary concern. This is a domestically driven, labour-cost-sensitive measure. The jump from 3.2% to 3.7% in a single month will keep the MPC cautious.
Monthly Highlights (May 2026 MoM)
| Category | MoM Change | Notes |
|---|
| CPI All Items | +0.2% | Same as May 2025 |
| Transport | +0.4% | vs -1.8% a year ago — large base effect |
| Air Fares | +10.3% | Easter timing distortion |
| Motor Fuel | +0.6p/litre | vs -2.1p/litre a year ago |
| Food & Non-Alcoholic Beverages | -0.1% | Main downward offset |
| Furniture & Household Goods | +0.8% | Still negative YoY |
Energy Price Cap — Key Forward Indicator
The UK's Ofgem energy price cap fell in April 2026, cutting household energy bills and pulling that month's headline inflation down. However, the cap is due to rise 13% in summer 2026, which will push energy costs to a two-year high. This is the single biggest known risk to UK inflation in the coming months.
Bank of England Policy Outlook
| Indicator | Current |
|---|
| Bank Rate | 3.75% (held at June 18 MPC meeting) |
| BoE 2% target | Still above |
| Services inflation (BoE threshold focus) | 3.7% — elevated |
| Iran-U.S. ceasefire impact | Easing near-term energy pressure |
| Energy price cap (summer) | Rising 13% — upside risk |
The MPC voted to hold at 3.75% at its June 18 meeting, as widely expected. The Iran-U.S. ceasefire has eased the most acute energy price pressure, but the Ofgem cap rise and persistent services inflation give the BoE reason for caution. Markets are not pricing in further rate cuts until at least Q4 2026.
Context
The May 2026 print came in below expectations for the second consecutive month, suggesting the Iran war's inflationary peak in the UK has passed faster than feared.
Cumulative price rises since 2021 remain painful: the ONS notes UK prices have risen approximately 22% over five years.
The peak CPI this cycle was 3.3% in March 2026, driven by the initial Iran energy shock. Analysts now believe that peak is behind us — barring the summer Ofgem cap rise.
The next CPI release is July 16, 2026 (June data).
