If you have information, or know something that should be investigated, you can contact the Channel 4 News Investigations Team.
Investigative journalism often depends on brave people having the courage to come forward to blow the whistle on wrongdoing, and provide crucial evidence.
Sometimes, those people are taking personal risks by getting in touch with journalists.
It can help our work if we know who you are, and if we are able to discuss the information with you, however sometimes we know that is not possible.
No system of communication is guaranteed to be secure, but below we’ve set out different ways you can contact us.
If you want to keep your identity secret, we will do our utmost to protect you. We take the protection of sources extremely seriously.
