An article in the Times this morning gives some more detail: 2017 will see a ?10 charge for pre 2005 vehicles entering the existing congestion zone, 2019 will extend to all pre 2015 diesels in the ULEZ and will be 24 hours a day, 7 days a week, and in 2020 that zone will be extended to the North and South circulars. Local taxis and Ubers will be exempt. I agree with the need for more control on polluting vehicles in theory, and think a line needs to be drawn somewhere regarding age of vehicles (pre 2005 seems about right to me), but pre 2015 seems far far too new to me (only 4 years old in 2019 - I've never ever been able to afford a 4 year old car!), and I disagree with the extension of the zone so quickly. I COMPLETELY DISAGREE on exempting taxi's and Ubers.
