The T-Charge (or ‘toxicity charge’) is being introduced on 23 October 2017 and will apply to all pre-Euro 4 petrol and diesel cars, broadly meaning most vehicles registered before the end of 2004. The T-Charge will cost £10 on top of the regular £11.50 congestion charge, meaning motorists with older cars entering the centre of London at peak times will have to pay a total of £21.50. Like the congestion charge, the T-Charge will run five days a week, Monday to Friday, between the hours of 7am and 6pm.
