ULEZ & CAZ Checker is a privacy-first web application built by T2 Automations.
Vehicle registrations and travel dates entered into this tool are processed strictly on-device in your browser. We never log, store, or sell vehicle number plates or travel destinations.
Calendar reminder files (.ics) are generated client-side and saved directly to your device.
Links to official payment portals (TfL, Gov.uk, Birmingham City Council) take you directly to official government payment processors.
