Southern Water Data Breach

Claim compensation for Southern Water data breach

Have you been affected by the Southern Water data breach?

Earlier this year, Southern Water revealed that some of its data had been breached. The security violation happened following an “illegal intrusion” into the company’s IT systems. In other words, a cyber-attack.  

A statement from Southern Water states that:  

Data belonging to 5-10% of customers has been stolen in the cyber-attack. However, Southern Water provides essential water services to 2.5 million customers and wastewater services to more than 4.7 million customers, so this has the potential to be a far-reaching data breach.

The following customer information is believed to have been accessed by cybercriminals:

FAQs about the Southern Water data breach

The following information is believed to have been accessed by cybercriminals:

This personal and financial information may have been stolen for sale on the dark web.

A statement from Southern Water says: 

“On Monday 12 February 2024 we announced that data from a limited part of Southern Water’s server estate had been stolen and was at risk following an illegal intrusion into our IT systems. This arose from our ongoing investigation into suspicious activity, as detailed in our statement on 23 January 2024.

We are very sorry that this has happened.

We continue to work with our expert technical advisers to confirm whose data is at risk. Our initial assessment is that this is the case for some of our customers and current and former employees.

We have engaged leading independent cybersecurity experts to monitor the “dark web”. They continue to report to us that, since we were named on the cyber criminals’ site on 22 January 2024, they have found no new evidence of the data potentially involved in this cyber incident being published online. They will continue to carry out their checks for as long as is necessary.

We take data protection and information security very seriously and, in accordance with our regulatory obligations, we are making contact with anyone whose personal data may be at risk.

Based on our forensic investigations so far, which are ongoing, we are notifying in the order of 5 to 10 percent of our customer base to let them know that their personal data has been impacted. We are also notifying all of our current employees and some former employees.

These notifications include security advice, as well as guidance on recommended precautionary steps and details of the support we are offering them. This support includes enhanced Experian credit monitoring, free of charge, for the next 12 months. The service provides active monitoring which can detect and help prevent fraudulent misuse of personal information.

Throughout this process we have been working with Government, our regulators and the National Cyber Security Centre. We have also notified the police and the Information Commissioner’s Office.

Since the incident, our IT security teams have worked with independent incident response experts, using enhanced monitoring and protection tools to check actively for any suspicious activity on our IT estate. Southern Water’s operations and services to customers have not been impacted.

Further updates will be posted on our website and social media channels as we know more. Please be assured that if at any point we have reason to believe your data may be impacted, we will notify you, in line with our regulatory obligations.


If you have specific questions relating to the cyber incident then please call 0330 303 0025.”

If you receive notification that you are affected by the data breach, register to receive updates on our investigation. We’ll let you know what’s happening, and if and when you can make a no-win, no-fee data breach compensation claim.   

A group action claim is where a group of people – sometimes even thousands of people – have been affected by the same issue. Group action cases are also known as class actions, multi-claimant, or multi-party actions. 

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.

What can you claim for?

While each case is judged on its own merits, there are some things we would typically look for when it comes to when claiming compensation following a data breach, cybercrime or other GDPR violation:

Financial loss

With stolen data, cybercriminals can make purchases using your bank and credit cards, apply for credit in your name, set up fraudulent bank accounts and access your existing online accounts.

Distress

GDPR failures, cybercrime and data breaches can have a significant impact on you, both mentally and physically. They can cause or exacerbate anxiety, stress and other psychological conditions.

Loss of privacy

Your data has value, and organisations must be held to account if they fail to protect your right to data privacy or otherwise do not uphold your GDPR rights.
 

How to protect yourself following a data breach or cybercrime

  • Contact your bank or credit card provider immediately if your financial data has been exposed.
  • Check all bills and emails for goods or services you have not ordered.
  • Check your bank account for unfamiliar transactions.
  • Alert your bank or credit card provider immediately if there is any suspicious activity.
  • Monitor your credit score for any unexpected dips.
  • Call Credit, Experian and Equifax to ensure credit isn’t taken out in your name.
  • Never provide your PIN or full password to anyone (even someone claiming to be from your bank).
  • Never been pressured into moving money to another account for fraud reasons. A legitimate bank won’t ask you to do this.
  • Follow the security instructions provided by the organisation that breached your data.
  • Never automatically click on any suspicious links or downloads in emails or texts.
  • Don’t assume an email or phone call is authentic just because someone has your details.
  • Be careful who you trust – criminals often use scare tactics to try and trick you into revealing your security details.
  • Know that, even if you recognise a name or number, it might not be genuine.
  • Don’t be rushed or pressured into making a decision. A trustworthy organisation would never force you to make a financial transaction on the spot.
  • Never provide your full password, pin or security code to someone over the phone (or via message). If a bank believes a transaction has been fraudulent, they will not ask for this information to cancel the transaction.
  • Listen to your instincts and ask questions if something feels “off”.
  • Refuse requests for personal or financial information and stop discussions if you are at all unsure.
  • Contact your bank or financial service provider on a number you know and trust to check if a communication is genuine.
  • Be cautious of unsolicited communications that refer you to a web page asking for personal data.
  • Don’t accept friend requests from people you don’t know on social media.
  • Review your online privacy settings.
  • Report suspected fraud attempts to the police and Action Fraud.
  • Register with the Cifas protective registration service to slow down credit applications made in your name.
  • Change your passwords regularly and use a different password for every account (a password manager can help with this).
  • Protect your devices with up-to-date internet security software.
