Flutter Entertainment is a multi-national sports betting and gambling company who own many popular betting and gambling sites such as Paddy Power and Betfair.
Flutter Entertainment plc experienced a significant cybersecurity incident in July 2025. Hackers accessed the data of up to 800,000 customers across the UK including usernames, email addresses, IP addresses, contact details and recent activity on the platform.
Paddy Power and Betfair contacted affected customers to alert them of the incident, providing some online safety advice.
In their email to affected customers, Flutter stated that: “There is nothing you need to do in response to this incident, however we recommend you remain vigilant.”
A spokesperson for Flutter later gave the following statement: “Our investigation concluded that the affected information was isolated to limited betting account information. No passwords, ID documents or usable card or payment details were impacted. We are informing all affected customers.”
Flutter should be in touch to notify affected individuals.

If we do launch a group action, there are no costs to join a claim. However, if your claim is successful, you may have to pay a ‘success fee’. This fee is taken from the compensation awarded to you. At KP Law, our success fee is competitive, and we make sure you are fully informed about any potential costs before you officially join our action. If you lose, you won’t have to pay a penny.
