What to report

These are the types of fraud and corruption against TfL we want to hear about:

  • Fraud within our supply chain (for example, overcharging by suppliers, rigged tenders, undisclosed gifts and hospitality or conflicts of interest)
  • Payment fraud (for example, payment diversion or cheque fraud)
  • Revenue fraud (for example, counterfeit ticketing, abuse of travel discounts or concessionary schemes, false claims for refunds or fraudulent avoidance of penalty charge notices)
  • Employee benefits fraud (for example, fraudulent pension claims, inappropriate overtime payments, undisclosed secondary employment, abuse of employee or nominee travel passes)
  • Theft or misuse of assets (for example, theft of spares or scrap, theft or sale of TfL property, misuse of TfL assets such as company vehicles)
  • Unauthorised access to TfL systems and confidential information

When you report your fraud or corruption suspicions, include as much information as possible so our team can fully investigate your concerns.

We understand that sometimes people do not want to be contacted, but adding your contact details on the form means our counter-fraud specialists can speak with you if necessary, and provide updates.

Our investigations are sensitive so we cannot always fully detail actions we have taken. Where appropriate, we aim to provide you with a conclusion.

What to do if you have been a victim of fraud

If you have personally been a victim of fraud on our transport system, report it directly to Action Fraud or the police (online or on 101), unless it's an emergency. They can provide you further help, advice and support.

Legal note

This form is for members of the public to report concerns that they may have about fraud or corruption affecting TfL. You are not classed as a whistleblower for the purposes of any report you wish to make using it. However, we do treat the information we receive in the strictest confidence.

Whistleblowing generally applies if you are a worker and you report certain types of wrongdoing to your employer. TfL has its own whistleblowing policy and procedure for its workforce.
