Privacy notice

In line with the EU General Data Protection Regulation (GDPR), there are certain things that we need to let you, a research participant, know about how your information will be processed. In this privacy notice, we explain the legal basis for data processing, who will have access to your personal data, how your data will be used, stored and deleted and who you can contact with a query or a complaint.

What is the legal basis for processing my data?

Transport for London (TfL) are the data controller for this project. This means that they are responsible for deciding the purpose and legal basis for processing data. For this project, the legal basis for processing the data is ‘public interest’, meaning that data processing is necessary for the performance of a task carried out in the public interest. Once a respondent has agreed to engage with the survey, data processing is carried out on the basis of their explicit consent.

The National Centre for Social Research (NatCen) and UCL’s Institute of Health Equity are data processors for this project (see below).

Who will have access to my personal data?

TfL will not be passing any of your personal data to either NatCen or UCL. If you decide to take part in the survey, you will be asked some personal information but only NatCen will have access to this.

How will my survey answers be treated?

The results collected are used for research purposes only.

NatCen will pass the survey responses to UCL who will analyse the data and write a report.

At the end of the research, all data will be anonymised before being passed on to TfL. Your personal information will be securely deleted once the project is complete.

Who can I contact with a query or a complaint?

If you have any questions about how your data will be used, please contact TfL’s Data Protection Officer:

Richard Bevins (

Under GDPR, you have the right to lodge a complaint with the Information Commissioner’s Office at

You also have to right to have your survey answers deleted. If you have taken part in the survey but would like to withdraw your data, please contact with your unique reference number, which can be found at the top of any letters or emails you have received about the survey.
