Fuel Price Transparency Still Elusive for Drivers

The UK’s competition watchdog, the CMA, has once again highlighted the need for greater transparency in fuel pricing, raising concerns that some retailers are not passing on wholesale price falls quickly enough to drivers. This lack of transparency is a long-standing issue that has left many motorists feeling frustrated and exploited by the fuel industry.

Since May, costs have fallen at fuel pumps, but prices remain significantly higher than before the Iran conflict, with retailer profit margins either at or above historically high levels seen in 2025. The CMA’s latest quarterly update reveals that some retailers did not immediately pass on falls in wholesale diesel prices to drivers between May and June.

The regulator has sent over a thousand warning letters to retailers and issued 53 compliance notices since April for failing to register with the Government-run Fuel Finder price comparison scheme. Around 97% of petrol stations are now registered, but the CMA will continue to monitor the road fuel market in the autumn to ensure customers are paying a fair price.

The issue is not new, but it continues to highlight the need for greater accountability from the fuel industry. The AA has long been vocal about high prices at forecourts, with President Edmund King stating that “clearly, some fuel retailers are prepared to pass on lower costs promptly and help their customers.” However, many more, including large numbers of supermarkets, are not.

The Fuel Finder system, created in response to a CMA recommendation in 2023, is a step towards greater transparency. But it only addresses part of the problem. The real question is why some retailers continue to resist passing on wholesale price falls to drivers. Is it simply a case of profiteering during times of uncertainty, or are there deeper structural issues at play?

A recent 10p-a-litre crash in wholesale petrol barely registered at the pump, with the UK average price trickling down just 0.4p a litre in seven days. Wholesale petrol costs have since rebounded, but remain 1p to 2p a litre lower than the peaks in mid to late July.

The Department for Energy Security and Net Zero has said that “forecourts must pass on any fall in wholesale prices to motorists quickly.” However, it’s clear that this is not happening. The CMA’s ongoing monitoring of the fuel market will be crucial in ensuring that drivers are not being taken advantage of by retailers who prioritize profits over transparency.

Ultimately, it comes down to trust. Drivers need to know that they can rely on retailers to pass on wholesale price falls quickly and fairly. Anything less is unacceptable, and it’s up to the CMA and other regulatory bodies to ensure that the fuel industry is held accountable for its actions.

The UK government has made commitments to increase transparency in fuel pricing, but it’s time for action. The Fuel Finder system needs improvement and expansion, with greater penalties for retailers who fail to register or pass on wholesale price falls. Regulators need to take a closer look at the structural issues driving up prices and profits.

Drivers deserve better than to be treated like pawns in a game of profiteering. It’s time for the fuel industry to step up and show that they can be trusted to put drivers first.
