UK petrol prices jumped approximately 5p per litre in just one week, a sharp move that reflects the broader damage the ongoing Iran conflict is inflicting on global energy markets. Brent crude climbed back above $100 per barrel on September 9, 2026, its highest level since July, as the war that began in late February shows no signs of cooling off.
For UK drivers, the math is painful. Pre-war petrol prices sat around 132p per litre. They’ve since surged to roughly 160p, a jump of about 28p per litre over the course of the seven-month conflict. Filling a typical 55-litre tank now costs around 15 pounds more than it did before the first airstrikes landed.
What’s driving the spike
The conflict traces back to February 28, 2026, when US and Israeli forces launched strikes against Iran. Since then, repeated cycles of military escalation have kept energy traders on edge and supply routes under threat.
The latest catalyst came in early September 2026, when US forces struck Iranian tankers. That move sent crude prices lurching upward, pushing Brent roughly 40% above its pre-war baseline of around $70 per barrel. Oil hadn’t touched triple digits since July, and traders had briefly hoped the worst of the price shock was behind them. It wasn’t.
