A breach of confidentiality happens when private information is disclosed to a third party without permission. This can occur when someone deliberately shares data they shouldn’t, accidentally reveals information, or when security systems fail. How serious a breach is depends on what information was shared, who got it, and what harm it might cause.
At Professional Saver, we’ve helped professionals protect themselves against confidentiality breaches for over 40 years. Our professional indemnity insurance shields individuals and businesses who handle sensitive client information. Whether you’re a consultant, designer, financial advisor, or healthcare worker, it’s vital to understand what constitutes a breach of confidentiality.
What Is a Breach of Confidentiality?
A breach of confidentiality is when private or sensitive data is shared without consent. This could be personal details, medical records, trade secrets, or business plans. For it to be a breach, the information must have been shared with an expectation of privacy. This privacy might be clearly stated in contracts or simply understood based on the situation.
Confidentiality duties come from several sources:
- Contracts – Terms in job contracts, client agreements, or non-disclosure agreements.
- Professional rules – Ethical standards for lawyers, doctors, or accountants.
- Laws – Legal requirements under data protection laws.
- Trust relationships – Duties that arise when someone trusts you with their information.
The setting matters too. Sharing client details with team members who need them for their work may be fine. But sharing the same details with outsiders without permission would likely be a breach.
What Are the Different Types of Confidentiality Breaches?
Confidentiality breaches happen in different ways. Knowing these can help you spot risks in how you handle information.
Intentional Breaches
Intentional breaches occur when someone knowingly shares confidential information without permission. This could include leaking trade secrets to competitors, selling customer lists to other companies or sharing private information for personal gain. In some cases, an individual reveals client details out of spite.
Accidental Breaches
Many breaches happen by mistake. These can include sending emails to the wrong person, leaving private papers in view of others, or talking about clients in public. In addition, someone may throw away sensitive documents without shredding them or lose devices that contain private information.
Systemic Breaches
Systemic breaches occur due to larger issues. For example, poor training on data protection, weak security systems, or a lack of access controls. It could also plainly be unclear confidentiality policies.
How Serious Are the Consequences of a Confidentiality Breach?
Breaking confidentiality can have serious consequences. The impact depends on what confidential information was shared and how it happened.
| Type of Damage | Possible Effects |
| Legal | Lawsuits, fines, court-ordered payments |
| Money | Compensation costs, legal fees, fixing the problem |
| Reputation | Loss of trust, damaged image, bad publicity |
| Career | Discipline, loss of licenses, career damage |
| Business | Loss of competitive edge, smaller market share |
The effects can be severe for regulated jobs like solicitors, accountants, and financial advisors. They might face discipline from their governing bodies, even losing their right to practice. Businesses can face fines up to £17.5 million or 4% of their yearly turnover for serious data protection breaches.
What Laws Cover Confidentiality?
Several key laws set confidentiality rules in the UK:
UK GDPR and Data Protection Act 2018
These laws set rules on how personal data must be handled and protected. They also grant individuals rights over their data, such as the right to access and delete it.
Common Law Duty of Confidentiality
This requires keeping information private when shared in confidence. It applies to all types of confidential information. It doesn’t matter whether it was shared in a personal, professional, or business context.
Contract Law
Contract law enforces confidentiality agreements between parties. Breaching these agreements can lead to legal consequences. This includes financial penalties and damage to professional reputations.
Intellectual Property Laws
These laws protect trade secrets and business information. They ensure that sensitive company information is kept secure from competitors.
Industry Rules
Industries like healthcare, legal, and financial services have additional confidentiality requirements. Professionals in these fields must follow strict standards to protect client information.
Understanding these laws helps professionals know their duties and the risks of breaches.
How Can Professionals Prevent Confidentiality Breaches?
Preventing breaches is better than dealing with them after they happen. Here’s how to reduce your risk:
- Create confidentiality policies explaining how to handle, store, and share sensitive information.
- Train your staff regularly on confidentiality duties and data protection.
- Use proper security measures such as:
- Password protection and encryption for files
- Secure storage for paper documents
- Limiting access to those who need it
- Regular security checks and updates
- Use confidentiality agreements when sharing sensitive information with others.
- Share information only on a “need-to-know” basis, limiting access to those who truly require it.
- Properly dispose of confidential information by shredding documents and wiping electronic storage.
- Have a breach response plan that outlines steps to take if a breach occurs.
- Get professional indemnity insurance to protect you financially if clients make claims.
While breaches often involve private data, some incidents may also result in third-party property damage or injury, making public liability insurance an important additional safeguard.
What Should You Do If a Breach Occurs?
Even with prevention, breaches can still happen. When they do, take these steps to limit damage:
- Stop the breach – Take immediate action to prevent further disclosure.
- Assess what happened – Find out what information was shared, who got it, and what might happen.
- Tell those affected – This may include the people whose information was shared, regulators, and sometimes the police.
- Document everything – Keep detailed records of what happened and what you did about it.
- Improve your security – Figure out how the breach happened and fix the problem.
- Call your insurer – If the breach might lead to claims or legal proceedings, notify your insurance provider right away. Having legal expenses insurance can help cover the cost of legal advice and representation.
For serious personal data breaches, UK law requires reporting to the Information Commissioner’s Office within 72 hours of discovering the breach.
