Public Sector Data Breach Claims

If you have been the victim of a public sector data breach, we can help.

Get justice for a public sector data breach violation

The public sector handles some of our most sensitive personal data, so a data breach can be disastrous.

Modern governance and the delivery of public services require sharing a wide range of our sensitive information. But reliance on unsecured legacy software and a lack of preparation for dealing with cyber-attacks has made the sector vulnerable.

As well as being lucrative to hackers, the public sector is also struggling to train its staff and put robust data management practices in place. So, human error remains the leading cause of breaches, and people across the country are left paying the price.

There are many different types of public sector data breaches to watch out for, including:

Local Councils. Almost 100 million cyber-attacks hit Britain’s local authorities in just five years. But it is human error rather than hackers that are the leading cause of breaches in the sector.

Social Services. Social Services safeguard and promote vulnerable children. As such, it deals with sensitive personal and personal data. If this information is breached, the consequences can be disruptive and upsetting.

Housing Associations. The number of incidents of data breaches is increasing across the housing association sector.

Health & Emergency Services. The NHS and the police handle a lot of sensitive personal data. So it is vital that this is robustly protected, and that officers, medical staff, and suppliers know how to work with this information securely. However, all too often, this is not happening.

Schools. A failure to invest in adequate staff data protection training means that data privacy violations are happening all too often in our local authority-run schools.

If you have been a victim of a public sector data breach, we can help you make a no-win, no-fee claim for compensation.

Mary and Ben’s* school data breach

Mary & Ben adopted Sarah when she was a baby. They planned to tell Sarah about her adoption when she was older. However, her local authority-run school sent documents referencing Sarah’s adoption to the wrong address. The information ended up with a neighbour who opened and read the documents before sharing Sarah’s adoption status with other people in the local community.

Sarah subsequently found out that she was adopted, leading to considerable distress for her and her family.

The emotional impact of the PFEW data breach should not be underestimated

The emotional impact of the PFEW data breach should not be underestimated. We all know the impact that theft can have on a person. Following a burglary, people often feel shock, anger, fear, helplessness, and panic. These feelings might develop immediately or be experienced much later. Cybercriminals are committing theft when they steal personal data, so it is understandable that some people feel upset; particularly as the PFEW effectively gave the burglar the keys.

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 loses

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.


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.
