UK petrol has risen to 175.28p per litre and diesel to 200.04p — both three-week highs — but the pace of increases is slowing sharply. Oil markets are falling on hopes of a Trump-Putin ceasefire summit. Here is what is happening and whether prices are about to turn.
Where prices stand right now
According to the government's weekly road fuel statistics for the week commencing 12 October 2026, petrol is averaging 175.28p per litre and diesel 200.04p. Both are up slightly on the previous week — petrol by 0.40p and diesel by 0.52p — but that marks the third consecutive week of increases since the Iran crisis pushed prices sharply higher in September.
The diesel-petrol gap has widened to 24.76p per litre, reflecting continued disruption to the global distillate market. For context, a year ago petrol was 134.15p and diesel 142.02p — UK drivers are now paying around 41p more per litre for petrol and 58p more for diesel than this time in 2025.
The rate of increase is slowing — fast
The most significant development is not where prices are, but how quickly they are moving. The weekly rise in diesel tells the story clearly:
- Week ending 20 September: diesel up 4.6p
- Week ending 27 September: diesel up 3.0p
- Week ending 4 October: diesel up 0.8p
- Week of 12 October: diesel up 0.52p
The same pattern holds for petrol. The crisis-driven price spike appears to be plateauing. Whether it turns into an actual fall depends largely on what happens in global oil markets this week.
Why oil prices are falling: the Trump-Putin summit
Brent crude dropped to around $61 per barrel this week — down nearly 3% — as markets priced in the possibility of a US-Russia ceasefire deal on Ukraine. Trump and Putin are expected to meet for another summit, with reports suggesting Budapest as the likely venue within the next two weeks.
The logic for oil traders is straightforward: a Ukraine ceasefire would remove the sanctions overhang on Russian oil supply, reduce geopolitical risk premiums, and potentially allow more crude onto world markets. The IEA has also warned of a growing supply glut in 2026, and US crude production hit a record 13.6 million barrels per day this month.
Separately, Trump cancelled a threatened military strike on Iran last week, which caused oil prices to drop around 5%. With the two biggest upside risks to oil — an Iran attack and an escalating Ukraine conflict — both receding simultaneously, the market is turning bearish.
What this means for UK pump prices
Oil price falls take time to reach the pump. The typical lag is one to three weeks, meaning the drop in Brent crude this week could start showing at UK forecourts from late October. However, the relationship is not guaranteed — retailers have been slow to pass on falls in recent months, a pattern the CMA has documented as "rocket and feather" pricing.
If oil stays around $61 and the ceasefire talks progress, a realistic expectation for November would be petrol drifting back toward 168–170p and diesel toward 190–195p. That is still elevated by historical standards but would represent a meaningful reduction from current levels.
The risk to that scenario is a breakdown in the Trump-Putin talks. Analysts at ING noted that de-escalation "would remove sanction risk from the oil market" — but the reverse is also true. Ukraine has rejected any deal that cedes eastern territory, and European governments remain opposed to lifting sanctions outside a comprehensive peace agreement.
Trump's diesel deal: how much diesel has actually arrived?
On 9 October Trump announced a deal with Putin to release Russian diesel onto global markets, with 300,000 tonnes pledged immediately. Four days later, there is no confirmed delivery. Russian Deputy Prime Minister Novak said supply could start "this month," but Russia's refining capacity remains severely damaged from Ukrainian strikes — down an estimated 60% since spring. Analysts at CSIS and the Energy Policy Research Foundation both said the price impact would be modest even if volumes arrived as promised.
Global diesel markets have not moved materially on the announcement, suggesting traders share that scepticism.
What to do right now
Prices are near a short-term peak and may begin to ease in the coming weeks — but they are not going to fall sharply overnight. In the meantime, the gap between the cheapest and most expensive local station remains significant. At current prices, the difference between the best and worst forecourt in a typical town is 8–12p per litre.
On a 55-litre fill, that is up to £6.60 saved by choosing the right station. Use the live map to find the cheapest station near you — prices update every 30 minutes from the government's Fuel Finder API.
