Official data confirms Consumer Prices Index increased to 3.3% in the 12 months to March 2026, up from 3.0% in February, with motor fuels providing the largest upward pressure.
UK inflation accelerated in March 2026 as rising oil prices pushed up costs at the petrol pump, according to official data released by the Office for National Statistics. The Consumer Prices Index rose to 3.3% in the 12 months to March, marking an increase from February’s 3.0% rate.
The Numbers Behind the Rise
Motor fuels provided the largest upward contribution to both the monthly and annual inflation rates, the ONS confirmed. On a monthly basis, CPI rose by 0.7% in March 2026 – more than double the 0.3% increase recorded in March 2025.
The broader CPIH measure, which includes owner occupiers’ housing costs, climbed to 3.4% annually, up from 3.2% in February. Yet core inflation – which strips out volatile energy, food, alcohol and tobacco prices – actually fell slightly from 3.2% to 3.1%.
This divergence highlights how energy costs are once again becoming a key driver of price pressures across the economy.
What’s Driving the Pressure
The Confederation of British Industry warned that further price increases may lie ahead. Alpesh Paleja, CBI economist, said the organisation’s survey data signals additional inflationary pressures building in the pipeline.
Clothing and footwear provided some relief, offering the largest downward contribution to annual rates. But this wasn’t enough to offset the impact of higher transport costs hitting household budgets.
CPIH goods prices accelerated from a 1.6% annual rate to 2.1%, while services inflation edged up from 4.2% to 4.3%. The split suggests both physical products and labour-intensive services are experiencing renewed cost pressures.
Bank of England Under Pressure
The March figures put the Bank of England’s Monetary Policy Committee in a challenging position. With inflation now well above the 2% target, policymakers face difficult decisions about interest rates in the coming months.
The UK’s 3.3% inflation rate also compares unfavourably with European neighbours – Germany and the broader EU both recorded 2.8% in March, as France managed just 2.0%.
The renewed acceleration in headline inflation comes despite core measures showing some moderation. This suggests the current spike may be driven by specific sectors rather than broad-based price pressures.
But with oil prices remaining volatile and the CBI flagging further increases ahead, the MPC will be closely monitoring whether March’s jump represents a temporary blip or the start of a more sustained inflationary period.

Key Takeaways
- UK inflation rose to 3.3% in March 2026, up from 3.0% in February, driven primarily by higher motor fuel costs
- Core inflation actually fell to 3.1%, suggesting the increase is concentrated in energy rather than broad-based price pressures
- The Bank of England faces renewed pressure with inflation well above its 2% target amid signals of further increases ahead
What This Means for Kent Residents
Higher petrol prices are already hitting Kent motorists hard, chiefly those commuting via major routes like the M20 and using the Dartford Crossing for work or business. Residents should consider using AA or RAC apps to compare local fuel prices and adopt energy-efficient driving habits to reduce costs. Kent County Council services may also face budget pressures from elevated inflation, potentially affecting everything from transport subsidies to social care provision across the county.
