How do I pay the ULEZ charge if my car isn't compliant?

You can pay the ULEZ charge on the TfL website, via the TfL app, by phone, or at selected Payzone retail locations. Payment can be made up to three days before entering the zone or by midnight on the third day after. 

Setting up Auto Pay automatically charges your registered payment method when your vehicle enters the zone. However, paying £12.50 daily quickly becomes expensive - investing in a ULEZ compliant used car from LMC offers better long-term value.
