Zero-Hours Contract Reforms Under the Employment Rights Act 2025: What It Means for Employers

Zero-hours contracts have long been a flexible staffing tool for UK employers, especially in sectors such as hospitality, retail, healthcare, social care, logistics, education, and events. They allow businesses to respond quickly to fluctuating demand without committing to fixed working hours. For many employers, that flexibility has been essential. For many workers, however, zero-hours arrangements have created uncertainty around income, scheduling, and job security.

The zero-hours contract reforms are designed to reduce one-sided flexibility and give workers more predictable working patterns. For employers, this does not necessarily mean the end of zero-hours contracts, but it does mean that casual workforce planning will need to become more structured, transparent, and carefully documented.

What Are Zero-Hours Contracts?

A zero-hours contract is an agreement where an employer does not guarantee a minimum number of working hours. The worker is usually offered work as needed, and in many cases, they may accept or decline shifts depending on the terms of the contract.

These contracts can work well where demand is genuinely unpredictable. For example, a hotel may need additional staff during busy holiday periods, or an events company may require workers only when bookings are confirmed. The problem arises when workers regularly work consistent hours over a long period but remain on contracts that provide no certainty.

The reforms aim to address that gap between the written contract and the reality of the working relationship.

Key Zero-Hours Contract Reforms Employers Need to Know

One of the most significant expected changes is the right for eligible workers to be offered a more predictable contract where they have worked regular hours over a defined reference period. In simple terms, if someone is repeatedly working the same pattern, employers may need to offer a contract that reflects those regular hours.

This could mean moving some workers from zero-hours arrangements to guaranteed-hours contracts. The exact rules may depend on the final legislation and supporting regulations, but the direction is clear: employers will be expected to justify casual arrangements where work patterns are no longer genuinely casual.

Another important reform concerns reasonable notice of shifts. Employers may need to give workers clearer advance notice when offering, changing, or cancelling shifts. Last-minute rota changes have been a major concern for workers on insecure contracts, particularly where they affect childcare, transport, second jobs, or household budgeting.

There may also be requirements around compensation for cancelled shifts. If an employer cancels work at short notice, the worker could become entitled to payment or another form of compensation. This is intended to discourage poor workforce planning and protect workers from financial loss.

What This Means for You as an Employer

For employers, the biggest impact will be on workforce planning. Businesses that rely heavily on zero-hours staff will need to review whether those arrangements still match operational reality. If a worker has been doing regular Monday-to-Friday shifts for months, calling the contract “zero-hours” may no longer be enough.

Employers should start by auditing their casual workforce. This means looking at who is on a zero-hours contract, how often they work, whether their hours follow a pattern, and whether they are genuinely free to turn work down. This review can help identify workers who may need to be offered more predictable terms.

Rota management will also become more important. Managers who currently make informal arrangements by text, WhatsApp, or last-minute phone calls may need clearer processes. Employers should consider setting internal deadlines for publishing rotas and rules for cancelling or changing shifts. A casual approach to scheduling could create legal and employee relations risks.

Contracts and policies will also need updating. Zero-hours agreements should clearly explain the nature of the arrangement, how work will be offered, whether the worker can refuse shifts, how notice will be given, and what happens if shifts are cancelled. Handbooks and manager guidance should be aligned with the new legal requirements.

The Risks of Getting It Wrong

The reforms are likely to increase the risk of disputes where workers believe they should have been offered more secure terms. Employers could face grievances, tribunal claims, reputational damage, and higher employee turnover if they fail to manage the changes properly.

There is also a practical risk. If employers do not prepare early, they may suddenly find themselves needing to convert large numbers of casual workers onto predictable contracts without having budgeted for the cost. This could affect staffing models, payroll forecasting, holiday pay calculations, and operational flexibility.

For growing businesses, the risk is not just legal compliance. It is also about trust. Workers who feel they are treated fairly are more likely to stay, accept shifts, and perform well. A transparent approach to working hours can improve morale and reduce recruitment pressure.

How Employers Can Prepare Now

Employers should take a proactive approach rather than waiting until the reforms are fully implemented. A sensible first step is to carry out a zero-hours contract audit. Identify which roles genuinely need flexibility and which roles have become regular in practice.

Next, review shift patterns over recent months. Where workers have consistent hours, consider whether a guaranteed-hours contract, minimum-hours contract, or part-time contract would be more appropriate. Employers do not need to remove all flexibility, but they should be able to explain why a flexible arrangement is necessary.

Training managers is equally important. Many compliance problems start at line-manager level, especially where rotas are changed informally or workers feel pressured to accept shifts. Managers should understand the new rules, the importance of notice, and the risks of treating zero-hours workers as if they are permanently available.

Employers should also improve communication with workers. Explaining why changes are being made can reduce confusion and resistance. It is better to present reforms as part of a fairer, more organised approach to work rather than as a purely legal exercise.

Practical Alternatives to Zero-Hours Contracts

Zero-hours contracts may still have a place, but employers should consider alternatives. A minimum-hours contract can provide a guaranteed baseline while allowing additional shifts when needed. A fixed-term contract may work for seasonal peaks or temporary projects. A part-time contract may be suitable where working patterns are stable but limited.

The right model depends on your business need. The key question is whether flexibility is genuinely required or whether you as the employer are just using zero-hours contracts by default. Under the new reforms, defaulting to zero-hours is likely to become harder to defend.

So, the take-home message is: Zero-hours contracts are not necessarily disappearing, but the way they are being used is changing. Employers who adapt to the coming changes now will be best placed to manage that change with confidence.
