Overview
- TfL says about £789m in unpaid Ulez penalty charge notices remains outstanding, with 94% owed by drivers holding four or more notices.
- Between January and June 2025, enforcement recovered roughly £16.5m, more than 530 vehicles were seized, and about 350 were auctioned for around £285,000.
- Cases are being escalated through county courts with options including wage deductions, property liens and, in extreme instances, bankruptcy proceedings.
- More than 97% of vehicles seen driving in London now meet Ulez standards, leaving a small non-compliant minority responsible for most penalties.
- TfL is using an intelligence-led approach with DfT and DVLA data-sharing, while noting issues such as camera or number-plate tampering and some rescinded fines.
