Exclusivity Clause Dispute Letter Template & Generator

If you need to challenge an unenforceable exclusivity clause in your zero hours contract, a written letter is the recommended first step — it creates a clear record and shows you're pursuing the matter formally. Below is what a strong exclusivity clause dispute should include, plus a free tool to generate yours.

What this letter needs to cover

• State the clause is unenforceable under the Small Business Enterprise and Employment Act 2015
• Confirm the worker is working or seeking work for another employer
• Request written confirmation the exclusivity clause will not be enforced
• Warn that enforcement may constitute a detriment

Why exclusivity clauses in zero-hours contracts are unenforceable

Under the Exclusivity Terms in Zero Hours Contracts (Redress) Regulations 2015, any clause preventing a zero-hours worker from working for another employer is legally unenforceable — this applies regardless of what your contract states, since the law specifically overrides such clauses.

What to include before you send it

• Reference to the specific exclusivity clause in your contract
• Confirmation that this clause is unenforceable under the 2015 Regulations
• A clear statement of your intention to seek or accept work elsewhere
• A request for confirmation that no action will be taken against you for doing so

Protection if your employer tries to penalise you anyway

If your employer subjects you to any detriment or dismisses you for working elsewhere despite this protection, this is itself unlawful — the exclusivity ban isn't just about the clause being unenforceable, it comes with real protection against retaliation for exercising this right.

Frequently Asked Questions

Does this apply to all zero-hours contracts, or only some?
This applies broadly to zero-hours contracts as defined in the regulations — it's worth confirming your specific contract genuinely falls within this definition if there's any doubt.

What if my employer threatens to reduce my hours if I work elsewhere?
This could itself amount to unlawful detriment connected to exercising your right to work for another employer, and is worth challenging directly.
