ULEZ compliant buses

Request ID: FOI-2126-2324
Date published: 02 October 2023

You asked

Please reply with details on when the existing buses on routes R11 , R1 , B14 and 233 were retro fitted to meet LEZ and the cost per bus. I find it quite amazing when you state that these buses have been adapted to meet low emission standards. We should all be party to and commitment to honesty and integrity in service between the elected and the electors.

TfL undertook a retrofit programme between 2017 to 2020 to ensure all buses in the fleet met Euro VI/ULEZ standards. Since January 2021, the entire bus fleet has met Euro VI emission standards and ULEZ standards.

We can advise that retrofit technology cost an estimated £20k per bus; this was funded by TfL.

If this is not the information you are looking for, please do not hesitate to contact me.
