UK petrol prices are at their highest level since the start of the Iran oil crisis, according to figures cited by the RAC. The average price of a litre of petrol in the UK is 158.5 pence. The reporting reflects a rise to this record point, framing it as the peak reached during the current period of heightened oil market pressure related to the Iran-linked situation. The sources do not provide additional regional breakdowns or comparisons to prior dates beyond the reference to the Iran oil crisis. Overall, the available information focuses on the single national average price level and the fact it is the highest recorded in that context. Other factors behind the change, such as wholesale costs, fuel duty, or exchange rates, are not detailed in the supplied excerpts.
