Question: what is the difference between congestion charge and ulez?
Answer: ULEZ is an additional charge on top of the Congestion Charge (£11.50). That means entering the CCZ in a car that's not exempt on a weekday will cost drivers a combined sum of £24. Motorists also need to know that the ULEZ charge resets at midnight and does not cover drivers for a 24 hour period over two days.
