How Do Zero-Hour Contracts Work in the UK? (2025 Law Explained)

A zero-hour contract in England & Wales is a flexible employment agreement where the employer has no obligation to provide minimum working hours, and the worker is not obliged to accept every shift offered. These contracts remain legal and popular in sectors like hospitality, retail, care, and events.

Workers on zero-hour contracts earn pay only for the hours they actually work. If no work is offered, there is no pay for that period. However, you are still protected by key statutory rights regardless of how irregular your hours might be.

What Employment Rights Do Zero-Hour Contract Workers Have in 2025?

Zero-hour contract workers in England & Wales are usually legally classified as ‘workers’, though sometimes as ‘employees’, which comes with varying levels of protection. From day one, you are legally entitled to:

• National Minimum Wage or National Living Wage for every hour worked.
• Paid annual leave (holiday pay), accruing as you work.
• Statutory rest breaks and maximum working hours (under the Working Time Regulations 1998).
• Protection against unlawful discrimination and whistleblowing.
• Payslips detailing pay and all statutory deductions.
• Auto-enrolment into a workplace pension (if eligible).
• After two years’ continuous service (as an employee), protection from unfair dismissal.

What Are Employers’ Legal Obligations for Zero-Hour Contracts?

Employers using zero-hour contracts must follow several strict legal guidelines to protect both parties. In 2025, the core obligations include:

• Providing a written statement of terms (contract) by the first day of work, in line with Section 1 of the Employment Rights Act 1996.
• Avoiding exclusivity clauses unless the worker’s earnings exceed the Lower Earnings Limit and a lawful exception applies—strengthened by the Workers (Predictable Terms and Conditions) Act 2023.
• Paying workers promptly, at or above the mandated minimum wage, for every hour worked.
• Ensuring workers accrue paid holiday at the correct statutory rate and receive accurate holiday pay.
• Adhering to agreed notice periods for shift cancellations and ensuring fair compensation when short-notice cancellations occur.

Which Clauses Should Every Zero-Hour Contract Include?

How to Request Guaranteed Hours or More Stable Work

As of 2025, under the Predictable Terms and Conditions Act, zero-hour workers in the UK can request a predictable working pattern (including guaranteed minimum hours) from their employer after 26 weeks of continuous service.

To request guaranteed hours:

1. Check Your Eligibility: You must have worked under your contract for at least 26 weeks (the work need not have been continuous, but your contract must be ongoing).
2. Draft Your Request: Clearly state you are applying for a more predictable working pattern under your statutory rights. Specify your preferred pattern or minimum weekly hours.
3. Submit in Writing: Send your request as a letter or email to your line manager or HR. Keep copies of all communications.
4. Wait for a Response: Your employer must reply within one month, either agreeing or refusing (and, if refusing, stating a valid business reason).
5. Appeal if Rejected: If your request is refused, you can challenge this through an appeal or seek guidance from Acas.

How to Review and Negotiate a Zero-Hour Contract (Step-by-Step)

Scrutinising and negotiating your zero-hour contract can determine your working conditions and pay. Here’s how to approach it:

1. Read Each Clause: Focus on hours, pay, shift allocation, cancellation, and your right to work for others.
2. Spot Banned Terms: Exclusivity clauses are generally unlawful on zero-hour contracts. Insist these are removed if present.
3. Review Cancellation Terms: Ensure the process for shift cancellation, notice period, and compensation is clear.
4. Check Holiday Pay Provisions: Make sure your entitlement and accrual method for holiday pay are clearly set out.
5. Understand the Disputes Process: Your contract should describe how workplace grievances are raised and resolved.
6. Negotiate Fair Terms: If any clause is unclear or weighted against you, highlight it and request a written amendment.
7. Confirm Agreed Changes in Writing: Any verbal agreement is not enough. Written confirmation is vital under UK law.

What Happens If My Shift Is Cancelled at Short Notice?

Shift cancellation at the last minute is a top concern for zero-hour workers. Your protections depend on your contract and statutory rules:

• If your contract sets out a cancellation procedure or compensation rule, your employer must follow it.
• If there’s no such policy, there is usually no guarantee of pay for cancelled shifts—unless repeated cancellations breach the implied duty of trust and confidence.
• Excess last-minute cancellations can be used as grounds for requesting a predictable work pattern under 2025 rules.
• Company policy or best practice may entitle you to compensation—whether or not the law requires it.

Are Exclusivity Clauses Still Legal in Zero-Hour Contracts in 2025?

Exclusivity clauses were banned in zero-hour contracts by law in 2015 and remain prohibited in 2025—unless your earnings exceed the Lower Earnings Limit and you explicitly agree otherwise.

• You cannot be prevented from accepting work with other employers.
• Any clause saying you must not work elsewhere, or need permission, is unenforceable for nearly all zero-hour workers.
• Dismissal or poor treatment for working elsewhere is unlawful.

Common Pitfalls and Mistakes in Zero-Hour Contracts: What to Watch Out For

Zero-hour contracts offer flexibility, but errors can leave both workers and employers vulnerable. Common pitfalls include:

• Failing to issue a proper written contract.
• Inserting or leaving in unlawful exclusivity clauses.
• Omitting clear details on shift allocation, notice, or compensation.
• Confusing worker status and rights—many wrongly believe zero-hour workers lack full protection.
• Miscalculating or failing to pay holiday entitlement.
