NDA vs Non-Compete vs Non-Solicitation (UK): What's the Difference?

NDAs, non-competes and non-solicitation clauses do different jobs and have very different enforceability in the UK. Here's how each works and when you need which.

These three get lumped together but do completely different jobs — and a court treats them very differently. Knowing which you actually need saves you from an unenforceable clause.

This is general information, not legal advice

NDASafe is a document preparation service, not a law firm. Our templates are legally reviewed against applicable UK law at the point of release, but every situation is different. Where significant value, unusual risk or a cross-border element is involved, take independent legal advice before you sign.

The three, side by side

ClauseWhat it doesEnforceability
NDA / confidentialityStops use or disclosure of confidential informationGenerally enforceable if reasonable in scope and duration
Non-competeStops working for a competitor for a periodRestraint of trade — only if reasonable and no wider than necessary
Non-solicitationStops poaching staff, customers or suppliersMore readily enforced than non-competes if narrowly drawn

Why non-competes are the hardest to enforce

A non-compete stops someone earning a living in their field, so UK courts start from the position that it is void and will only uphold it if it protects a legitimate interest and goes no further than reasonable — the test refined in Tillman v Egon Zehnder. Over-wide drafting is the usual reason they fail. See are NDAs enforceable for the reasonableness principle.

What you usually need

Start with confidentiality — an Employee NDA or Freelancer NDA. Add narrowly-drawn non-solicitation if poaching is the real risk, and a reasonable non-compete only where genuinely justified.

Confidentiality plus optional, reasonable restraints

The NDASafe Employee NDA covers confidentiality with the mandatory carve-outs, plus optional non-solicitation and non-compete blocks drafted with the Tillman reasonableness test in mind. £29, or £79 for all eight.

Frequently asked questions

What's the difference between an NDA and a non-compete?

An NDA protects confidential information — it stops someone using or disclosing what they learned. A non-compete restricts where a person can work or who they can work for after they leave. They address different risks and have very different enforceability tests.

Are non-compete clauses enforceable in the UK?

Only if reasonable. A non-compete is a restraint of trade and is void unless it protects a legitimate business interest and goes no wider than necessary in scope, geography and time (Tillman v Egon Zehnder [2019] UKSC 32). Courts may sever an offending part if it can be cleanly removed.

Which do I need?

Almost everyone needs an NDA. Non-compete and non-solicitation clauses are for protecting against a departing employee or contractor competing or poaching, and should be drafted narrowly. NDASafe's Employee NDA includes optional, reasonably-drafted non-solicitation and non-compete blocks.
