The UK competition watchdog will review pricing strategies this autumn after finding some retailers slow to pass on lower wholesale diesel costs at the pump.
Fuel retailers face a detailed Competition and Markets Authority review of pricing strategies this autumn after diesel pump prices failed to track lower wholesale costs in May and June, the watchdog said Monday.
CMA chief executive Sarah Cardell said the regulator expected wholesale price drops to be “rapidly and fully passed on to drivers” and would keep monitoring margins closely.
The CMA found some retailers were slow to cut diesel prices when wholesale costs fell between May and June. Pump prices dropped overall in June as wholesale costs eased, but remain significantly above levels before the conflict in the Middle East. The watchdog said it had found no evidence retailers actively changed pricing to exploit the crisis.
“Passive pricing strategies” are the bigger concern. The CMA said the widespread use of such strategies is contributing to persistently high margins. Some retailers failed to reflect lower wholesale diesel costs at the pump in a timely manner.
The autumn review will examine how fast wholesale moves appear at the pumps, why prices differ between local areas, and whether specific retailers follow a pattern.
The AA echoed the criticism. AA president Edmund King said some retailers pass on lower costs promptly, but “many more, including large numbers of supermarkets, are not.”
The CMA has also stepped up enforcement on the Fuel Finder price-comparison platform, sending 1,166 letters to retailers and issuing compliance notices covering 53 sites since April over registration requirements. No financial penalties have been needed yet; most registration issues were resolved after the CMA contacted the sites.
About 97% of UK petrol stations are now registered with Fuel Finder, representing an estimated 99% of fuel sold. The platform is designed to help motorists compare pump prices and pressure retailers to compete.
This is the CMA’s latest intervention in the road fuel market. Three years ago it found competition had weakened, prompting earlier measures to increase price transparency.
