In today’s digital age, personal data breaches have become a significant concern for businesses worldwide. With the growing volume of sensitive information being stored and transmitted electronically, protecting data from unauthorised access is crucial. The Information Commissioner’s Office (ICO) enforces data protection standards in the UK. This article will discuss four circumstances when reporting a data breach to the ICO is mandatory. This will ensure your business complies with data protection law.
Breach of Personal Data
The first example of when your UK business must report a data breach to the ICO is when there has been a breach of personal data records. Personal data is any information that can directly or indirectly identify a living individual, whether through:
- their names;
- addresses;
- contact details;
- financial information; and
- health data.
If a data breach occurs, and there is a significant risk to the rights and freedoms of individuals, it is essential to report it to the ICO. The ICO defines a significant risk as one that could result in:
- discrimination;
- financial loss;
- reputational damage;
- or other substantial social or economic disadvantages.
The ICO expects UK businesses to thoroughly assess the potential impact before businesses determine if they should report it. If the violation is likely to result in harm, the ICO requires you to notify them within 72 hours after you become aware of the breach.
Breach Affecting a Large Number of Individuals
The second scenario where reporting a data breach to the ICO is mandatory is when the breach affects a large number of individuals. The definition of a ‘large number’ may vary depending on the circumstances. Still, it generally refers to either a breach that impacts:
- a significant portion of the affected data subjects; or
- a substantial segment of the business’s customer base.
When a data breach occurs, organisations need to assess the scale and potential consequences of the incident. If the violation affects a substantial number of individuals, regardless of the nature of the data compromised, it must be reported to the ICO. This requirement ensures that the ICO can:
- evaluate the situation; and
- take appropriate action to protect the affected individuals.

Breach Involving Sensitive Personal Data
The third example pertains to breaches involving sensitive personal data. Sensitive personal data includes information about an individual’s:
- race;
- ethnic origin;
- political opinions;
- religious beliefs;
- genetic and biometric data;
- health information; and
- sexual orientation.
The UK GDPR places additional emphasis on protecting this data category due to its potential for significant harm if misused or mishandled.
If a data breach occurs, and it involves the unauthorised disclosure, alteration or loss of sensitive personal data, businesses are required to report it to the ICO. The ICO expects organisations to have appropriate safeguards in place to protect such data. Any breach involving sensitive personal data is considered a severe violation of data protection laws.

Breach Affecting Critical Infrastructure
The fourth scenario where reporting a data breach to the ICO is mandatory is when the breach affects critical infrastructure. Critical infrastructure refers to systems and assets, both physical and virtual, that are essential for the functioning of society and the economy. This includes energy, transportation, healthcare, finance and communications sectors.
Suppose a data breach occurs within a business operating critical infrastructure if it can potentially disrupt the functioning of essential services or pose a significant risk to public safety. In that case, it must be reported to the ICO. Reporting such breaches is crucial for ensuring a swift response and mitigating the potential impact in the broader community.
Key Takeaways
Data breaches can have severe consequences for both businesses and individuals. Therefore, the ICO requires businesses to promptly report such incidents. Many business owners obtain expert legal advice regarding the potential harm, size, sensitivity and public importance of the information subject to the security breach. If you fail to report a breach, you may face hefty fines of up to £17.5m, so it is vital to report breaches.
By understanding these scenarios and complying with reporting requirements without undue delay, your business can uphold its responsibilities in protecting individuals’ personal data and maintaining data security. Prompt reporting enables the ICO to assess and address breaches effectively, fostering a safer digital environment for all.

Frequently Asked Questions
Because the ICO views personal data breaches as high risk in nature, given the impact they can have on individuals (for example, putting them at risk of identity theft or fraud).
The ICO will likely conduct a formal investigation and consider a hefty fine against your company. The ICO will fine your organisation more than if you had reported the breach on time to deter other companies from avoiding self-reporting requirements.
