Compare Heating Oil Prices & Save

The United States stepped up economic pressure on Iran this week to reopen the Strait of Hormuz, the shipping lane that carried about a fifth of the world's oil before it shut in late February. Iran's foreign minister says a deal with Oman is close, but that nothing moves until Washington eases sanctions and pays war reparations. Brent crude, the benchmark that sets what refineries pay for oil, finished the week above $88 a barrel after gaining more than 5%.

That has worked its way through to the tank. Our price tracker puts the UK average at just under 89ppl today, so a 1,000-litre fill costs about £889. A week ago the average was closer to 86ppl, which is roughly £30 less for the same delivery.

The bigger comparison is with last summer. The same fill cost about £534 in the middle of August 2025, so heating oil is around two thirds dearer than it was a year ago. Prices are still below the 93ppl reached on 22 July, and a long way below the 135ppl peak of late March.

Two things decide where this goes next. The first is whether Iran and Oman can settle how the shipping lanes through the strait are divided, which is the point the talks keep sticking on. The second is the autumn restock, when households start filling tanks before winter and demand climbs back from its summer low.
