Follow up from FOI-1754-2324
Thank you for finding some answers to my Freedom of Information Act requests. I would like:
- Full answers instead of a link in relation to questions:
4 "Who concluded that 9/10 cars are ULEZ compliant? I am certain you are aware that this number is misleading. TFL’s statistics from 2022 show that 6/10 cars are non-compliant."
, 5 "What location did King’s College London measure the air quality information that is on TFL’s website? What date and time was this conducted?
What were the variables?
How did they make it a fair test?" , 8 "What is the outstanding total of TFL's current debt as of August 2023?"
- Individual costs for the labour that TFL paid workers to fit the new ULEZ cameras (reference to question "How much has been spent for installation of the new ULEZ cameras?") And the sum of money spent on the production of the new ULEZ signs (reference to question "How much money has been spent on the new ULEZ signage?")
I would like a full breakdown of the £45m - £55m cost.
- I would appreciate if you could find out how long Sadiq Khan has known Jonathan Swift

TfL Ref: FOI-2632-2324
Thank you for your follow up request which we received on 23 October 2023, asking about the ULEZ expansion.
Your request has been considered in accordance with the requirements of the Environmental Information Regulations (EIRs) and our information access policy. I can confirm that we hold some of the information you require. You asked:
4 "Who concluded that 9/10 cars are ULEZ compliant? I am certain you are aware that this number is misleading. TFL’s statistics from 2022 show that 6/10 cars are non-compliant."
As explained on our website here, the nine in ten cars figure for November 2022 was calculated by cross-referencing data obtained from our Automatic Number Plate Recognition (ANPR) cameras with vehicle data provided by the Driver and Vehicle Licensing Agency (DVLA). This method of calculating compliance is based on the vehicles detected driving in the zone rather than vehicles with a registered address in London. More recent data from the London-wide ULEZ first month report, published on 31 October 2023, indicates that 95 per cent of vehicles seen driving in outer London are now ULEZ compliant.
5 "What location did King’s College London measure the air quality information that is on TFL’s website? What date and time was this conducted? What were the variables? How did they make it a fair test?"
The data is supplied by LondonAir, which is provided by the Environmental Research Group from Imperial College London. Their website provides details on how the data is produced including which pollutants are included, when the data is collected, where the monitoring stations are in London and how accurate the data is. Further information on air quality monitoring and its methodology can be found here https://www.londonair.org.uk/LondonAir/guide/Monitoring.aspx. If you have any further questions about the data, I’d recommend you direct them to Imperial College London.
8"What is the outstanding total of TFL's current debt as of August 2023?"
- Individual costs for the labour that TFL paid workers to fit the new ULEZ cameras (reference to question "How much has been spent for installation of the new ULEZ cameras?") And the sum of money spent on the production of the new ULEZ signs (reference to question "How much money has been spent on the new ULEZ signage?")
I would like a full breakdown of the £45m - £55m cost.
The current estimated cost to supply and install the ANPR cameras and associated supporting infrastructure for the London-wide ULEZ is in the range of £45-55m.
The current estimated cost to supply and install the signage and associated infrastructure (which includes, design, supply, and installation) is in the range of £20-25m.
Unfortunately, in accordance with the EIRs, we are not obliged to supply any further breakdown as it is subject to a statutory exception to the right of access to information under regulation 12(5)(e) – confidentially of commercial or industrial information where such confidentiality is provide by law to protect a legitimate economic interest. In this instance the exception has been applied to the breakdown of the cost for installation and labour as disclosure would be likely to prejudice our commercial interests, as well as those of the companies concerned. Prejudice would be likely to occur when we go out to tender for this and similar services in the future, because it would be likely to result in a clustering of bids based on how much we are prepared to pay. Disclosing this information could also be prejudicial to our contractor’s ability to compete for tendering opportunities with TfL and other companies in the future, as their competitive edge would inevitably be prejudiced by disclosure of a detailed breakdown of their price. The use of this exception is subject to an assessment of the public interest in relation to the disclosure of the information concerned. TfL recognises the need for openness and transparency by public authorities but in this instance the public interest in ensuring that TfL is able to obtain the best value for public money outweighs the general public interest in increasing transparency of our processes.
- I would appreciate if you could find out how long Sadiq Khan has known Jonathan Swift.
