The London Ultra Low Emission Zone was introduced in April 2019 and covered the same area as the London Congestion Charge. You have to pay a fee if you don’t meet the required emissions criteria.Fortunately, 100% electric cars pass the test and are not required to pay the ULEZ charge. However, you must register your vehicle with Transport for London. From 25 October 2021, the ULEZ expanded from central London to create a larger zone up to, but not including, the North Circular Road (A406) and South Circular Road (A205).
