UK drivers are feeling the squeeze at the pumps in 2026. Diesel has climbed to an average of 191p per litre and petrol sits around 158p, with prices continuing to rise. Here's what's behind the increases and what you can do about it.
Why Are Fuel Prices Rising?
The Fuel Duty Cut Is Ending
The 5p-per-litre fuel duty reduction introduced in 2022 is being phased out from September 2026, with full inflation-linked rises planned from April 2027. This alone will add at least 5p per litre to pump prices, with further increases to follow.
Global Oil Prices
Renewed tensions in the Middle East pushed Brent crude above $85 per barrel in early 2026 after Iran announced restrictions on shipping through the Strait of Hormuz. Higher oil prices feed directly into pump prices within weeks.
Diesel Premium
Diesel continues to carry a significant premium over petrol, averaging over 30p per litre more. This is driven by higher refining costs, increased demand from commercial vehicles, and reduced European refining capacity.
How to Reduce Your Fuel Costs
Shop Around
Fuel prices can vary by 20p per litre between stations just a few miles apart. Supermarket forecourts typically offer the best prices. Use a price comparison app before you fill up.
Drive Efficiently
Simple changes to your driving style can cut fuel consumption by 15% or more:
- Drop from 70mph to 60mph on the motorway
- Accelerate gently and read the road ahead
- Keep tyres at the correct pressure — under-inflated tyres increase consumption by up to 10%
- Remove empty roof racks and clear unnecessary weight from the boot
Check Your Car's Efficiency
Run a free car check to see your car's official fuel economy figures and annual fuel cost estimates. Use our tyre check to find the correct pressures for your car — it's one of the easiest ways to improve MPG.
Consider Your Commute
If you drive to work, calculate whether a monthly train or bus pass might be cheaper at current fuel prices. For shorter commutes, an e-bike or cycling could save you thousands per year.
What's Coming Next
With the fuel duty cut ending and oil prices volatile, most analysts expect prices to remain high through 2026 and into 2027. Drivers of diesel cars will be hit hardest. If you're considering your next car, it's worth looking at the running cost differences between petrol, diesel, hybrid and electric — our car check shows annual fuel costs for any vehicle.
