Last Updated 16th September 2025. Suffering a data breach can be distressing and financially damaging. If you’re considering taking legal action, our data breach compensation calculator can help.
In this guide, we explain what a UK GDPR breach is and how a compensation calculator can help when estimating what could be awarded in a successful personal data breach claim.
The laws around the safe use of your personal information are tighter than ever since the introduction of new data security legislation. Under the new laws, if data has been breached because those who were handling it (data controller or processor) failed to adhere to data protection laws, and it causes distress, then you could have a right to be compensated.
If data controllers or processors (those organisations that handle personal data) are found not to be applying the UK General Data Protection Regulation (UK GDPR) and The Data Protection Act 2018 properl, theyy could suffer a fine from the governing body called the Information Commissioner’s Office (ICO). It could also enable you to seek compensation for emotional distress and financial trouble if your personal data is breached as a result.

When Can UK GDPR Breach Compensation Claims Be Made?
You could be eligible for compensation for a data breach if you can prove the following:
- The data breach was caused by the organisation’s failures.
- Your personal data was compromised in the breach.
- As a result of your personal data being breached, you suffered mental harm or financial loss.
Personal data is any information that could directly identify you or could identify you in combination with other information. Your name, home address, and national insurance number are all classed as personal data. In the next section, we will provide more examples of what could be classed as personal data.
A personal data breach is a breach of security that leads to the accidental or unlawful alteration, destruction, or loss of personal data. It also included the unauthorised disclosure or access to personal data.
Per the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018 (DPA), any organisation that processes the personal data of UK residents must do all that they can to keep it safe. This could include ensuring that they update their cybersecurity measures and provide efficient data protection training to all staff members. If you can prove that an organisation’s failings caused your personal information to be compromised, you could make a claim for your data breach.

Types Of Sensitive Or Personal Data
In order to interact with virtually every type of business or organisation, both online and offline, we are obliged to provide details about ourselves. Some of this information is required by law. We trust that the organisations that retain and use this data are doing so in accordance with UK GDPR law. For example, you may need to provide:
- Name and address
- Email address
- Date of birth and disclosed ethnicity
- Details of dependants
- Housing and employment details
- Bank information
- Affiliations with religious groups
- Biometric data such as fingerprints
The ICO calls these pieces of information ‘identifiers’, which means that they can be used to identify you.
Who Can Claim For A UK GDPR Breach?
Data breach victims may only discover the breach long after the initial problem occurred. Companies are legally required to report a serious data breach to the ICO within 72 hours. Also, they should contact any customer or service user affected to alert them.
If you are subjected to a personal data breach, you can do the following:
- Raise a complaint with the organisation that breached your data as soon as you become aware
- The ICO does not pay compensation either, but their involvement can lend weight to your claim.
- Start to assemble evidence of the financial or emotional toll the data breach has taken on you
- Reach out for help with a data breach solicitor
Tracking a data breach back and obtaining proof that the party involved caused the issue through positive wrongful conduct are essential. Professional help can organise this. Furthermore, a solicitor can ensure that you calculate all the costs to you caused by the problem. After a successful data breach claim following a UK GDPR breach, a compensation calculator could help to estimate what you may be awarded.
Data Breach Claims – What Are The Time Limits?
If you are claiming data protection breach compensation, you need to start your claim within the time limit. There are two different time limits involved with data breach claims. The time limit will depend on the nature of the organisation you are claiming against.
Generally, you must start your claim within six years of the incident.
When making a claim against a public body, such as a local council, the time limit to start your claim is typically only one year.
Call our advisors to learn how much compensation for a data breach you could get if you are within the time limit or what factors could affect the data breach compensation amount.

Examples Of Data Breaches You Can Claim Compensation For
Before discussing examples of compensation for a data breach, it would be helpful to explore different scenarios in which a valid UK GDPR breach claim might arise.
Some examples of when a personal data breach could occur may include:
- Your personal data is stolen during a cyber attack due to an organisation not updating its cybersecurity measures.
- Your personal information is sent to the wrong postage address, despite the company having your correct home address on file
- An organisation sends a group email, but accidentally shares your email address with other recipients because they failed to use blind carbon copy (BCC)
- Your employer verbally discloses your personal data to an unauthorised party without a lawful basis for doing so.
Our data breach solicitors have helped countless clients secure UK GDPR breach compensation amounts in the UK. Get in touch at any time to arrange a free consultation and to see if you could be eligible to work with one of them.
Should I Report My Data Breach?
If you are concerned that your personal data was breached by an organisation, then you should report this issue. We advise that it is best to take control of the breach as soon as possible to prevent further harm or losses and support your claim for data breach compensation.
If you are suspicious that an organisation has breached your data, you should report the issue to them by:
- Sending them an email or;
- Sending them a letter
It is also important to keep a record of any correspondence regarding the breach between yourself and the organisation. This may be used as evidence to support your claim.
You can also report the breach to the Information Commissioner’s Office (ICO). Not only will this support your claim, but the ICO may help to control the breach and limit the impact it has on you.
If an organisation suffers a data breach that affects the rights and freedoms of data subjects, it must be reported to the ICO within 72 hours of discovering the data breach. If a data subject would like to make a report, they must not wait longer than three months since their last meaningful conversation with the organisation.
After reporting your data breach, it may benefit you to get in touch with our helpful advisors. They can help determine whether you are eligible to start a data breach compensation claim and explain GDPR breach compensation amounts with you.
Evidence You’ll Need To Claim UK GDPR Breach Compensation
When you make any kind of UK GDPR breach claim, it’s your responsibility to prove that the organisation or company responsible for your data failed to comply with data protection law.
To do this, you’ll need to support your data breach claim with evidence. This might include:
- Correspondence with the ICO.
- Medical records or a letter from a psychiatrist detailing how the breach has affected you mentally.
- Receipts, bills, bank statements, and other financial documents that prove the financial losses you’ve suffered.
- Statements or communication with the other party.
- The results of an ICO investigation.
One of the benefits of making a data breach compensation claim with the help of a solicitor is that they can handle this step. They can talk to witnesses who have seen how the breach has affected you, contact an independent medical professional to arrange an assessment, and collate your financial losses.

UK GDPR Data Breach Compensation Calculator
Our UK GDPR data breach compensation calculator can give you a useful insight into what you could be awarded, but you may also like to know how data breach compensation works.
There are two types of harm for which you can seek compensation. One is material damage, which means the impact of a data breach on your financial situation. That might mean:
- You’ve missed work due to the stress of the situation.
- The breach meant you had to move house, at your own expense.
- A data breach badly affected your credit score.
Material damage will address these things. Sharing proof of your loss, such as bank statements or payslips, will be vital.
When a data breach calculator asks you what mental harm you have suffered due to the breach, it is looking to estimate harm from non-material damage. During your claim, those responsible for reaching a data breach compensation amount will attempt to value your psychological injuries.
They might get support from a set of guideline compensation figures from the Judicial College Guidelines (JCG). We’ve used the document and its brackets to make the table, which you might find handy as a guide.
In case you are wondering, you can seek a payment for both material and non-material damage or for just one of them. If you’d like to learn more about using a data breach compensation calculator or would appreciate a more detailed review by an advisor, simply call the number above.

Frequently Asked Questions (FAQs) On Using A Data Breach Compensation Calculator
Below, you can find answers to questions we often get asked about using a data breach compensation calculator.
What Exactly Does A Data Breach Compensation Calculator Estimate?
A calculator can give an indication of potential compensation by considering both financial losses and emotional harm caused by a breach. However, it does not cover every type of damage or guarantee a final payout.
Are Calculator Estimates Legally Binding Or Final?
No. Figures from a data breach compensation calculator are only guidelines. The actual amount may be higher or lower depending on the evidence in your case and how liability is established.
How Accurate Are Data Breach Compensation Calculator Figures?
They are only as accurate as the information entered and cannot account for every factor, such as long-term mental health issues or future identity theft risks. A solicitor’s advice is needed for a tailored assessment.
When Should I Use A Compensation Calculator Versus Speaking Directly To A Solicitor?
Calculators are useful for quick estimates. But if you have significant financial losses, ongoing distress, or complex circumstances, speaking to our data breach solicitors is the best way to understand your full entitlement.
What Information Do I Need To Use A UK GDPR Data Breach Compensation Calculator?
You’ll usually need details of the type of data involved, any direct financial losses, evidence of emotional distress, and any costs such as credit monitoring or identity restoration services.
Will The Calculator Ask About Identity Theft Or Credit Monitoring Costs?
Some calculators may not account for these costs. In practice, these expenses can form part of a claim, so it’s important to keep receipts or records to evidence them.
Can A Calculator Accurately Assess Future Or Ongoing Harm Linked To A Data Breach?
Not fully. While it may show broad ranges for distress, calculators cannot reliably estimate long-term or future risks. Solicitors consider both past and potential future impacts.
How Does A Compensation Calculator Treat Cases With Both Financial And Psychological Harm?
Some calculators separate these categories, while others combine them. In real claims, both types of loss can be included and assessed together to determine the full compensation.
Will Using The Calculator Affect Deadlines Or Limitation Periods For Making A Claim?
No. Using a calculator does not trigger or change legal deadlines. In the UK, you generally have six years to bring a data breach claim, or one year if it involves a public body.
