Britain's Competition and Markets Authority confirmed Thursday it is investigating parking tickets issued to drivers who were queuing at petrol station forecourts — fines of up to £100 per notice — as part of a broader regulatory review of the private parking industry.

The CMA's inquiry, announced via its official case register, targets what the authority describes as potentially unfair enforcement practices. Private operators, who manage the majority of off-street car parks in England and Wales under the Protection of Freedoms Act 2012, issue penalty charge notices independently of local councils and are subject to different appeals rules.

A driver queuing for a pump can find a notice issued by an Automatic Number Plate Recognition camera before the queue has moved ten feet.

The CMA has not named specific operators under investigation. The authority holds powers under the Consumer Rights Act 2015 to seek court undertakings or injunctions against businesses found to be engaging in unfair commercial practices.

The petrol station ticket probe runs alongside the regulator's existing scrutiny of private parking more broadly — a sector that collected an estimated £1.8 billion in charges and fines in 2023, according to the British Parking Association's own published figures.

The CMA did not specify how many tickets are under review. The operators declined to comment.
