Report suspected fraud or corruption

Transport for London has a zero-tolerance approach to fraud and corruption. If you know about or suspect fraud or corruption against TfL, report it in confidence to our Counter-fraud and Corruption team to investigate.

Here are some examples of the types of fraud and corruption against TfL which 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

Reporting your suspicions

Please only report suspected fraud or corruption if it is against TfL.

If you wish to query:

  • Unrecognised Oyster Card transactions or Penalty fare notices issued on our network. See our Help and Contact page for more information.
  • Congestion charges. For contact information visit our contact congestion charge page.
  • Penalty Charge Notice (PCN), vehicles evading the Ultra Low Emission Zone, or any other question about ULEZ, visit our contact ULEZ page.

Due to the volume of reports received it is important that you direct your query to the most appropriate department, as we are unable to respond to reports regarding the above queries.

When you report your fraud or corruption suspicions, include as much information as possible on the electronic form on this page.

Once you push the send button, the information will be sent to the Counter-fraud & Corruption Team at TfL. This will allow the team to fully investigate your concerns.

We would encourage you to provide your contact details on the form. This will allow our counter-fraud specialists to speak with you, if necessary. However, we understand that sometimes people do not wish to be contacted.

Due to the sensitive nature of our investigations, we cannot always provide full details of actions we have taken. Where appropriate, we aim to provide you with a conclusion.

If you have not provided us your details, we will not be able to provide updates.

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.

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.
