Action Fraud is the UK’s national fraud and crime reporting centre. It provides a central point of contact about fraud and financially motivated internet crime. It offers an online reporting tool or you can call and speak to an advisor on 0300 123 2040. You can also use its online form, which takes 20 minutes to complete. After reporting a scam, you'll get a national crime reference number and the case will be referred to the National Fraud Intelligence Bureau for analysis, by the City of London Police. Not every report results in an investigation, but each helps build a clearer national picture about fraud.
