What do I do if I think someone is committing benefit fraud?
You can tell us about this in two ways
Calling our benefit fraud hotline:
0808 1624043 Monday to Friday 8.00am and 5.00pm
When you call this number you will be asked for information about the person you think is committing fraud, including the type of fraud, their personal details, their appearance and whether they have a partner who is also committing fraud. It doesnt matter if you dont know all this information - any details you can supply may be helpful.
