UK Employment Rights: Redundancy, Leave, Contracts and Workplace Protections

Do I Have to Sign an NDA When I Leave a Job UK?

You are not legally required to sign an NDA when leaving a job. NDAs are most common in settlement agreements. Here's what they cover, your rights, and when they are enforceable.

Salary and income data is based on ONS and other official UK statistical sources. Figures are averages and may not reflect your individual circumstances.

NDAs at the end of employment are common — but not compulsory. Understanding what they can and cannot cover protects you from signing away rights you did not intend to lose.

When NDAs Are Used at Job Departure

ContextTypical NDA purpose
Settlement agreementConfidentiality of settlement terms and circumstances
Compromise of disputed claimsPrevent public disclosure of claims
High-value employeesProtection of commercially sensitive information
Discrimination or harassment settlementIncreasingly regulated; whistleblowing carve-outs required

What an NDA Cannot Prevent

By law, an NDA cannot stop you from:

  • Reporting a crime to the police
  • Making a protected disclosure (whistleblowing) to a prescribed regulator
  • Reporting to the EHRC (Equality and Human Rights Commission) or another regulator, where this qualifies as a protected disclosure
  • Making a personal injury claim you were not aware of when you signed
  • Seeking legal advice about the NDA itself
  • Telling your solicitor or (under some interpretations) close family about the situation

Clauses purporting to restrict these rights are void — they have no legal effect.

For a settlement agreement (and any NDA within it) to be legally binding:

  • You must receive independent legal advice from a qualified solicitor or adviser
  • The adviser must confirm they have advised you on the terms and effect of the agreement
  • The adviser must be identified and sign a certificate within the agreement

This means you always have a professional reviewing the NDA before it becomes binding — do not rush this process.

Negotiating NDA Terms

Key points to negotiate:

  1. Carve-outs: ensure you can discuss with close family, GP, and mental health professionals
  2. Duration: NDAs should be time-limited where possible
  3. Scope: narrow confidentiality to specific information, not everything about your employment
  4. Agreed reference: request a specific form of words the employer will use as a reference
  5. Non-disparagement: ensure any such clause applies equally to both parties

What NDAs Cannot Legally Do in the UK

Under current whistleblowing law (the Public Interest Disclosure Act 1998, now part of the Employment Rights Act 1996) and EHRC guidance, NDAs in employment cannot:

  • Prevent you from reporting a crime to the police or a law enforcement authority
  • Prevent you from making a protected disclosure (whistleblowing) that qualifies under the Public Interest Disclosure Act 1998
  • Stop you from seeking legal advice about the NDA itself (your solicitor is not bound by it)
  • Prevent you from discussing the matter with a mental health professional, under most interpretations

An NDA that attempts to suppress any of the above is void to that extent — you cannot sign away these protections even if you try to.

A further, broader ban is coming but is not yet in force. The Employment Rights Act 2025 will make void any NDA clause that stops a worker discussing or disclosing a harassment or discrimination allegation more generally (not just to a regulator) — but this specific provision is still subject to government consultation and is expected to be implemented during 2027, not September 2026. Don’t assume this wider protection already applies; check gov.uk or ACAS for the current implementation status.

Before signing any NDA as part of a settlement:

  • There is no statutory minimum amount an employer must contribute to your independent legal costs — this is a matter of negotiation, not law. In practice, employers typically contribute in the range of £500–£1,000+VAT (sometimes more for complex cases), because without some contribution most employees would not get the advice needed to make the agreement binding
  • You must receive independent legal advice for the NDA (as part of a settlement agreement) to be legally valid
  • Ensure you understand exactly what you are and are not permitted to discuss
