LEZ is being upgraded to euro6 from next year, this is entirely separate to the ULEZ requirements which are also being implemented at the same time.
Daily charge for any commercial vehicle will start at £100 per day and is in operation 24hrs a day.
Edit. This suggests that this is not going to be implemented until October 2020. I am fairly sure that yesterday I read implantation has been brought forward to coincide with the ULEZ, I will check Monday. https://tfl.gov.uk/modes/driving/low-emission-zone/about-the-lez
Been down the rabbit hole following that link and still can't find anything along the lines of Euro 6 in the LEZ. There is planned extension of the ULEZ and changes to LEZ in 2020 for heavy vehicles (3.5 tonnes) but nothing about vans in the LEZ.
