The UK petrol price has hit a new Iran war high, reaching 160p per litre at forecourts, adding to the financial pressure on millions of households. This surge reverses the earlier fall to 151p in early July, which followed a brief Middle East ceasefire. As families prepare for summer holidays, the rising cost of fuel is a significant concern for drivers across the nation.
Why Are UK Petrol Prices Rising?
The recent escalation in the Iran conflict has disrupted oil supplies through the Strait of Hormuz, a critical shipping route. Brent crude rose above $90 a barrel after Iran's Islamic Revolutionary Guard Corps struck two tankers and turned away four others. This geopolitical tension directly impacts wholesale fuel prices, which retailers pass on to consumers.

The RAC reports that diesel has also climbed to 179p per litre, up 14.5p, though it remains below its April peak of 192p. Simon Williams, RAC head of policy, warns that diesel could reach 185p in the coming weeks if oil prices stay high.
Impact on Households
Filling a family car with unleaded now costs around £88, while a diesel tank is £10 more. This comes at a particularly bad time, as 20.5 million UK drivers plan to take holidays by car, according to AA polling. The added expense strains household budgets already stretched by inflation and other living costs.

Fuel prices had eased in mid-June after a US-Iran memorandum extended a ceasefire, but renewed US strikes on Iran have reignited tensions. Donald Trump's administration has shown impatience with peace efforts, leading to retaliatory attacks on US allies in the region.
Comparison of Fuel Prices Over Time
| Date | Petrol (p/L) | Diesel (p/L) |
|---|---|---|
| Early July (post-ceasefire) | 151 | 164.5 |
| Current (Iran war high) | 160 | 179 |
| April peak | — | 192 |
| November 2022 (post-Ukraine invasion) | 160 | — |
As shown, petrol is at its highest since November 2022, when prices soared after Russia's invasion of Ukraine. Diesel, while below its April high, is expected to keep rising, adding to the financial burden on hauliers and commuters.
Key Takeaways for UK Drivers
- Petrol prices have hit 160p per litre, a new Iran war high.
- Diesel is set to rise further, potentially reaching 185p.
- Filling a family car now costs £88 for petrol and £98 for diesel.
- Geopolitical tensions in the Middle East are the primary driver.
- Drivers should monitor prices and consider fuel-efficient driving.
While wholesale petrol eased slightly this week, the RAC notes it's not enough to lower pump prices. The situation remains volatile, with any further escalation likely to push costs higher.
What Can Households Do?
To mitigate the impact, drivers can compare fuel prices using apps, combine trips, and maintain proper tire pressure to improve fuel efficiency. Planning ahead for holiday travel can help avoid unnecessary mileage. Additionally, considering public transport for short journeys may reduce overall fuel spending.
Future Outlook
Barring a significant drop in oil prices, diesel is expected to rise to 185p per litre in the next few weeks. The UK government faces pressure to address fuel costs, but immediate relief seems unlikely. As the Iran conflict continues, households must brace for sustained high fuel prices.
