A Londoner’s car was clamped after receiving multiple Ulez fines, despite driving a vehicle that complies with the clean-air scheme’s rules.

The driver is a health care professional who relies on their car to travel to access patients. In order to use their car to be able to successfully do their job, they had to fork out almost £600 to get their vehicle unclamped.

The Londoner, who owns a compliant 2021 Hyundai Hybrid, changed the number plate to a personalised one when they purchased the vehicle in May last year.

They have speculated their choice to personalise their registration number could have led to the penalty notices.

Transport for London (TfL) had acknowledged that the driver’s vehicle was compliant after the driver flagged to them that they had received multiple penalty notices.

The driver explained: "To my surprise, I received an Ultra Low Emission Zone (Ulez) penalty charge notice on June 9, despite the vehicle being compliant with Ulez standards. Two more charges followed. I challenged these and, meanwhile, received more penalties."

Despite withdrawing these fines on multiple occasions, one was not cancelled, and the driver’s car was subsequently clamped in December.

They continued: "As a health professional, I need access to my vehicle to attend to patients. I had to pay nearly £600 to get my car unclamped."

A TfL spokesman said: "We are working on ways to increase the frequency of the updates.

"Should any customer find this has happened to them, we urge them to contact us as soon as possible with the appropriate documentation so we can ensure their vehicle is registered as meeting the standards."

It is understood that the driver's £600 has since been reimbursed.

Sadiq Khan’s controversial clean-air scheme was expanded in August last year to Greater London with drivers of non-compliant vehicles now expected to pay £12.50 a day to drive into the city.
