At CDER, we welcome the latest TfL update on tackling persistent evasion of ULEZ Penalty Charge Notices. The fact that 94% of outstanding debt arises from persistent evaders underscores the importance of robust enforcement measures that protect both fairness and public funds.
Enforcement is not about targeting the majority of responsible drivers—who either comply with emissions standards or engage constructively when a charge arises—but about ensuring that the small minority who repeatedly ignore their obligations do not undermine the system. Every pound recovered, such as the £16.5m reinvested by TfL back into the transport network in the first half of 2025, directly benefits Londoners by funding cleaner air and better transport services.
As an ethical enforcement provider, we are committed to carrying out this work with professionalism and fairness. We recognise that some individuals may face genuine financial hardship, which is why we tailor our approach on the basis of each individual’s circumstances – click the links to find out more about our approach and how we use innovative technology to support it.
Where persistent non-payment is a matter of deliberate avoidance, however, it is right that enforcement is used to protect the integrity of the scheme and ensure fairness for the law-abiding majority.
Ultimately, compliance with ULEZ not only supports environmental progress but also ensures that those who follow the rules are not disadvantaged by those who do not. Enforcement, carried out ethically and proportionately, remains a key part of that commitment.
