Overview
In 2022, South Staffordshire Water experienced a huge data breach. The privacy violation affected both South Staffs Water and Cambridge Water, which are owned by South Staffordshire Water plc.
The breach happened when criminals stole personal and financial information from water company customers, potentially affecting a quarter of a million people. Employee data may also have been compromised.
Personal information, including bank details, was potentially leaked on the dark web following the cyber-attack and customers of both water companies could be at risk.
If your personal data has been compromised, you may be entitled to compensation. Register your interest today and we will keep you updated if one of our regulated UK partner law firms is able to take a claim forward.

In August 2022, South Staffordshire Water, the parent company of South Staffs Water and Cambridge Water, confirmed a cyber-attack. C10p (otherwise known as Clop) claimed responsibility for the breach. Clop is a Russian-affiliated crime group. Clop demanded a ransom for the stolen data, but said negotiations “broke down”. The hackers also claimed that they could change the chemical composition of the water, but stressed they were “not interested in causing harm to people”. South Staffordshire Water rejected claims that Clop could poison water supplies.
