The Competition and Markets Authority has tried to strike a careful balance in its June 2026 road fuel monitoring report. The regulator says the latest rise in pump prices was driven mainly by higher wholesale fuel costs after the conflict in the Middle East, not by retailers rewriting their pricing approach to profit from the crisis. That is the reassuring part of the update. The less reassuring part is that the CMA still sees a market with weak competitive pressure, leaving UK drivers exposed to prices that stay higher for longer than they might in a more active market.

According to the CMA, wholesale price increases explain most of the rise seen in March and into April. Where some retailers did record higher margins, the regulator says that was linked partly to following competitors' price moves, managing supply constraints and inventory pressure, and dealing with differences in purchasing costs. In other words, the CMA is not accusing retailers of crisis profiteering. But it is saying the market did not behave in a way that gave motorists much comfort. Prices moved up quickly, while competitive pressure to limit the squeeze remained weak.

This is where margins matter. The gap between what petrol stations pay for fuel and what they charge drivers stayed historically high across both supermarket and non-supermarket operators. In April, the average retail margin reached 11.3p per litre, with some individual retailers increasing slightly even as inventory levels improved and wholesale costs began to stabilise. For households, that detail is not just technical. High margins mean the bill at the pump can remain sticky even after some pressure in the supply chain starts to ease. For the CMA, it is further evidence that the pricing problem looks structural rather than temporary.

The regulator's bigger concern is the same one it flagged in its 2023 market study: too many forecourts appear to be pricing passively. Instead of cutting prices to win customers, retailers often seem to align with local competitors. That may make commercial sense for operators, but it is poor news for drivers who depend on local competition to bring prices down. Sarah Cardell, the CMA's chief executive, said the watchdog expects any reduction in wholesale costs to be passed through quickly and fully. That sets a clear test for the weeks ahead. If supply conditions improve but pump prices stay elevated, the argument that this is simply a wholesale-cost story will look less convincing.

There is a practical consumer angle here too. The CMA says drivers can save up to £9 a tank by shopping around, especially through navigation apps and comparison services backed by Fuel Finder. The point of the scheme is simple: when motorists can see local prices more easily, retailers have a stronger reason to compete. That may sound small beside the wider geopolitics of oil and fuel supply, but it is one of the few levers households can use immediately. In a market where pricing remains patchy, a short detour or a quick check before filling up can still make a noticeable difference over a month.

The broad pricing pattern has not changed. The CMA says supermarkets remain, on average, the cheapest places to buy fuel and continue to lead the market on price. Motorway service stations remain the most expensive, charging a sizeable premium for convenience. For motorists, that is a reminder that where they buy can matter almost as much as when they buy. For policymakers, it underlines a more uncomfortable truth: even outside motorway sites, the UK road fuel market still does not look as competitive as it should three years after the CMA first raised the alarm.

The next checkpoint comes in August, when the CMA will publish a longer-range update covering developments through to the end of June. That should offer a clearer read on whether stabilising wholesale prices and better inventory levels are finally feeding through to the forecourt. Beyond that, the watchdog plans to engage directly with retailers as part of a more detailed review of pricing strategies, with results due in the autumn. That follow-up may matter more than the headline finding that there was no evidence of deliberate crisis exploitation. The bigger issue for drivers is simpler: when costs ease, do prices fall quickly enough? So far, the CMA is not ready to say yes.
