The Ultra Low Emission Zone’s daily charge has already accrued more than £30m in revenue for Transport for London (TfL) since its launch in April.

More than £30m has already been taken by TfL since the London ULEZ was implemented in April

The numbers are further added to with 223,952 penalty charge notices (PCNs) have been handed out to drivers for non-payment of the charge between 11 May and 31 August, according to research by car selling comparison website Motorway.co.uk that made a Freedom of Information request to TfL in September.

31,783 drivers have received more than one penalty ticket since the ULEZ was launched and the worst offender has amassed 81 penalty notices between 11 May and 31 August.

Car, motorcycle and van drivers who fail to pay the daily charge of £12,50, face a £160 fine, or £80 if paid within a fortnight. While, HGV and coach drivers, who have to pay a higher daily charge of £100, face a £1,000 fine, or £500 if paid within 14  days.

Transport for London confirmed that until 10 May they issued warning notices rather than PCNs, because the ULEZ scheme was new.

Motorway.co.uk research found that over two million vehicles (2,124,404) have paid the Ultra Low Emission Zone (ULEZ) charge between launch and 31 August, generating almost £31m for TfL. Of this, £25.9m was paid by car, motorcycle and van drivers (ULEZ Low charge of £12.50) and £4.8m by HGV and coach drivers (ULEZ High charge of £100).
