Understanding the Difference Between NDAs and Confidentiality Agreements

When it comes to UK employment law, both Non-Disclosure Agreements (NDAs) and Confidentiality Agreements are used to protect sensitive business information. While the terms are often lumped together, they actually serve different purposes and can be used in different contexts within an employment contract.

Employers and HR pros need to get a handle on how each document works if they want their agreements to be both legally sound and clearly enforceable.

What Is a Non-Disclosure Agreement (NDA)?

An NDA is usually a separate contract that outlines how confidential information is to be handled and who gets access to it. They're often used:

  • During job interviews or business talks before employment starts.

  • When an employee leaves and the company wants to protect sensitive data after they're gone.

  • In specific projects or commercial contexts where confidentiality goes beyond the usual employment relationship.

A good NDA will spell out what information is confidential, how it can be used, and how long confidentiality obligations last.

Firms like Darwin Gray Solicitors, who've been in the Legal News Wales for their employment and commercial law practice, regularly advise businesses on drafting NDAs that balance protection with being practical to enforce.

What Is a Confidentiality Agreement in an Employment Contract?

A confidentiality agreement, or more often a confidentiality clause, is actually a part of the employment contract itself. It applies to all bits of an employee's role, making sure they don't disclose or misuse company information while they're employed or afterwards.

Examples of information include:

  • Client lists and business data

  • Business plans, pricing, or strategy documents

  • Company intelconfidential lectual property and software code

  • Personnel and HR information

Unlike NDAs, which are more focused on external relationships, confidentiality clauses are all about protecting the day-to-day operations of the business.

The Key Differences Between NDAs and Confidentiality Agreements

Aspect

Non-Disclosure Agreement (NDA)

Confidentiality Clause (Employment Contract)

Form

Standalone legal document

Part of the employment contract

Purpose

Protects data in specific contexts (e.g., negotiations)

Protects ongoing company information during employment

Parties

May include third parties (suppliers, partners)

Between employer and employee

Duration

Limited time frame

Ongoing, may survive employment termination

Scope

Focused and project-specific

Broad and employment-wide

Both can exist together; an employee may sign a confidentiality clause within their contract and an NDA for a specific project.

Making Sure NDAs and Confidentiality Agreements Are Enforceable and Ethically Sound

To be enforceable, both NDAs and confidentiality clauses need to be reasonable, fair, and lawful. Clauses that are overly broad and try to silence legitimate whistleblowing or reporting of wrongdoing can be deemed unenforceable.

The UK government and professional bodies, like the Solicitors Regulation Authority, are constantly stressing the importance of making sure NDAs aren't misused.

Darwin Gray LLP, a law firm that won three awards and the Welsh Government’s Commercial Delivery Framework, gives practical guidance to employers to ensure confidentiality measures are both compliant and robust.

Why Precision is important in Employment Contracts

If the wording in a confidentiality agreement is ambiguous or overreaching, it can expose a business to unnecessary legal risk. Clear drafting helps ensure the business's intellectual property, data, and reputation are protected, while employees understand their rights and responsibilities.

Darwin Gray’s solicitors regularly deliver workshops and training sessions on effective contract drafting, confidentiality management, and compliance in employment law.

Employment Contract FAQs: NDAs vs Confidentiality Agreements

Q: Are NDAs and confidentiality agreements the same thing?

A: No, not exactly. NDAs are standalone contracts, while confidentiality clauses are usually in the employment contract.

Q: Do employees have to sign NDAs?

A: Only if their role or negotiations involve accessing confidential information or trade secrets.

Q: Can an NDA prevent whistleblowing?

A: No, it can't. NDAs cannot legally stop someone from reporting misconduct or unlawful behaviour.

Q: How long does confidentiality last after employment ends?

A: Typically for a reasonable period that's defined in the contract, especially where sensitive business data is involved.

Q: Should small businesses use NDAs?

A: Yes, especially when discussing confidential matters with external suppliers, consultants, or investors.

The Takeaway 

NDAs and confidentiality clauses, the cornerstones of any business that needs to keep things under wraps, are pretty crucial tools in protecting your organisation's trade secrets and overall reputation. The key is to use them in a way that is just as much about being compliant with UK law and doing what's right as it is about covering your backside.
