Iran's president has said it would be better to end the war now, while Tehran is still in a position of strength. It is the clearest signal yet that Iran is looking for a way out, but on the same day Washington promised its toughest sanctions on the country so far. Oil held steady on Friday after two straight weeks of gains.
Brent crude, the benchmark that sets what refiners pay for oil, is around $94 a barrel and near its highest since July, and kerosene has climbed with it. Our price tracker puts the UK average at 89ppl today, so a 1,000-litre fill costs about £890. That is a shade below yesterday, the first fall after four days of rises.
The gap with last year is the bigger story. The same fill cost about £525 in late August 2025, so heating oil is about 69% dearer than it was a year ago. Today's price is still around 4ppl below the 93ppl high reached at the end of July.
Two things decide where a fill goes next. One is whether Iran's words turn into actual talks, the other is how hard the new sanctions bite. Oil is still moving in the meantime, with the American navy saying it has escorted more than 660 million barrels through the Strait of Hormuz, the sea lane that normally carries about a fifth of the world's oil, since early May.
