Counter fraud

Environmental programmes

We take allegations of fraud very seriously. To find out how to report suspected fraud within a government environmental or social programme, or to learn more about our role in preventing fraud, please see our section on Counter fraud.


If you wish to share information that you believe highlights potentially dangerous or illegal behaviour by a company whose activities we regulate, you should contact our whistleblowing team. This is not a consumer line.

You blow the whistle when you raise a concern about a wrongdoing, risk or malpractice that you are aware of through your work.

You can find full guidance on our whistleblowing policy and procedure, including contact details and information on your right to protection and anonymity in our section: Whistleblowing
