On 25 October 2021, the Ultra Low Emission Zone (ULEZ) expanded from central London up to (but not including) the North Circular and South Circular roads. The new zone is 18 times the size of the central London zone and now covers 3.8 million people. Most vehicles driving in the ULEZ must meet tight emission standards or pay the daily charge.
All vehicles except EVs and the like have to pay the congestion charge and always have done.
From 25th October vehicles that do not meet the emission regulations have to pay the ULEZ charge which covers the area outside the Congestion Charge zone. The Jazz (certainly from 2006) meets these emission regulations and does not have to pay the ULEZ charge but has to pay the congestion charge - as it always has.
