Our response

Transport for London (TfL) publishes details of income from all road user charging schemes, including the Congestion Charge and ULEZ, in its Annual Report and Statement of Accounts.

It is a statutory requirement that any net revenue generated by our road charging schemes (the ULEZ, LEZ or the Congestion Charge) is reinvested back into London’s transport network, including investing in improving transport links in outer London. 

Some of the programmes that the London-wide ULEZ net revenue will be spent on are detailed in the Four-Year General Programme published on the TfL website. For further information, you may wish to contact TfL at [email protected]

The GLA does not hold information regarding the volume of traffic since the introduction of the congestion charge. You may wish to send a further request to TfL at [email protected]

If you have any further questions relating to this matter, please contact us, quoting 
reference MGLA290823-5132.
