Introduction

Zero-hour contracts give UK retail employers the flexibility they need to match staffing to demand, but the Employment Rights Act 2025 has changed the rules. Scheduling zero-hour workers without a structured process now carries real legal and financial risk, and with retail employment declining by four percent through to 2025 according to Deputy's Big Shift Report 2026, the sector can't afford to get this wrong. This guide covers the new legal requirements, a step-by-step compliant scheduling workflow, retail-specific scenarios, and how the right technology can help. Implementation dates are expected from 2027, but preparation starts now.

The scheduling compliance gap in UK retail

Zero-hour contracts are widespread in UK retail. According to ONS zero-hours contract data, over a million people in the UK are employed on zero-hours contracts, with the retail and hospitality sectors among the heaviest users. Yet most employers still manage rotas informally, relying on spreadsheets, WhatsApp messages, or last-minute phone calls to fill shifts. Under the Employment Rights Act 2025, continuing to manage rotas informally creates serious legal and financial exposure.

The legal picture is shifting. Guaranteed-hours offers, shift-notice requirements, and short-notice compensation mean your scheduling decisions now have direct legal consequences. Every rota you publish, every shift you cancel, and every change you make inside the notice window is a potential compliance event. ACAS provides detailed zero-hours contracts guidance for employers working through these obligations.

Retail faces compounding pressures on top of regulatory tightening. Employment in the sector has declined, wages are rising, and the workforce is getting younger. Deputy's Big Shift Report 2026 found that Gen Z represents 44% of retail shift workers in 2025, up from 39% in 2024. This generation expects app-based, transparent scheduling, not a text message at 10 p.m. the night before a shift. Effective retail workforce management now means combining compliance with the experience younger workers expect.

The operating model for shift work is moving toward greater transparency, predictability, and accountability. This is both a regulatory trend and a workforce expectation. And the gap between those expectations and how most retailers actually schedule zero-hour workers is where the risk sits.

This article connects the legal framework to the practical scheduling workflow retailers need, covering compliance requirements, a step-by-step process, and how the right tools can help.

What the Employment Rights Act 2025 changes for zero-hour scheduling

The Employment Rights Act (ERA) 2025 received Royal Assent and introduces three provisions that directly affect how you schedule zero-hour workers. Implementation is expected from 2027, subject to final regulatory guidance. For a comprehensive overview of all ERA 2025 provisions and timelines, see the ACAS guidance on the ERA 2025.

The right to request guaranteed hours after 12 weeks

Under current provisions, workers on zero-hour (or low-hour) contracts can request a guaranteed-hours contract after a reference period of approximately 12 weeks. As the Big Shift Report 2026 puts it, the ERA 2025 "marks a structural shift in how flexibility is defined and regulated," with the guaranteed-hours right at its centre.

What this means for your rotas: you need to track cumulative hours for every zero-hour worker to know when they approach the threshold. Once a request is made, you need a documented process for responding (accept, offer an alternative, or decline with a valid reason under the Act). For broader context on tracking entitlements, Deputy's leave management guide covers related obligations.

In retail, high-turnover teams and seasonal surges make tracking these thresholds complex. A Christmas temp who starts in October could hit the 12-week mark before the season ends. Without a system to flag it, you won't see it coming.

Reasonable notice requirements for shifts and cancellations

The ERA 2025 requires you to give "reasonable notice" when scheduling, amending, or cancelling shifts for zero-hour workers. The exact notice periods are subject to secondary legislation, but the principle is that notice should be proportional to the length of the shift. The government's Make Work Pay consultations will determine the final requirements.

Last-minute rota changes, which are common in retail, now carry compliance risk. You need a documented trail showing when shifts were offered, when changes were communicated, and what the original rota looked like. Informal changes via group chat won't cut it.

Short-notice cancellation compensation

If you cancel or curtail a shift without giving reasonable notice, the worker is entitled to compensation. The compensation is proportional (details subject to secondary legislation, but the principle is established in the Act).

This turns poor scheduling practices into a direct cost. If you rely on cancelling shifts based on footfall, you need to rethink that approach. Every cancelled shift inside your notice window now comes with a price tag.

How to schedule zero-hour workers compliantly

The following workflow maps each scheduling action to a specific legal requirement or best practice under the ERA 2025.

Step 1. Build your rota with documented shift offers

Stop treating your rota as an informal request. Publish it as a formal shift offer with a clear record of who was offered what, when, and how they responded.

Use a system that timestamps when shifts were offered and to whom. Give workers the ability to accept or decline (zero-hour workers have no obligation to accept any shift). Keep records of every offer and response.

A platform like Deputy timestamps shift offers automatically and logs worker responses, giving you the audit trail you need without extra admin.

Step 2. Set and enforce notice periods for shift changes

Define your notice periods in advance. For example, set a 48 or 72-hour window before the shift start, depending on shift length. Build these notice windows into your rota process so any change inside the window triggers a review.

Document every change: the original shift, the amendment, and the timestamp. This paper trail is your defence if a worker raises a dispute.

With Deputy, you can configure notice-period rules so that changes inside your defined window are flagged before they're published. That gives you a checkpoint rather than an after-the-fact problem.

Step 3. Track hours toward the guaranteed-hours threshold

Set up a tracking mechanism for every zero-hour worker's cumulative hours over rolling 12-week periods. Flag workers approaching the threshold so you can prepare your response before a request arrives.

This isn't a one-time check. It's a rolling calculation that changes every week. Without a system doing the maths, you're relying on someone remembering to check a spreadsheet.

Deputy tracks hours across shifts and locations automatically through its time tracking tools, so you can see when workers are approaching the guaranteed-hours reference period without manual calculations.

Step 4. Create a process for cancellations and short-notice changes

Define what counts as a "cancellation" versus a "change" in your rota policy. When a cancellation falls inside your notice window, calculate and document the compensation owed. Having a clear shift swap policy can reduce the number of outright cancellations by giving workers a way to trade shifts instead.

Track cancellation patterns too. Frequent short-notice cancellations suggest a forecasting problem, not just a compliance problem. If one location or one manager consistently cancels shifts at the last minute, that's a signal to fix the root cause.

Step 5. Audit and improve your rota process regularly

Review your rota data monthly. Look at notice-period compliance rates, cancellation frequency, and hours-threshold progress across your team. The CIPD ERA 2025 tracker is a useful resource for staying current on implementation dates and regulatory updates.

Identify patterns. Are certain locations, days, or managers showing higher cancellation rates? Use the audit to improve your demand forecasting, which reduces the need for last-minute changes in the first place.

Deputy's reporting tools let you pull cancellation data, notice-period compliance, and hours tracking into a single view, so your monthly audit takes minutes rather than hours.

Retail-specific scenarios you need to plan for

The compliant workflow above covers the basics. But retail throws specific curveballs that you need to plan for.

Scheduling for seasonal peaks without breaching notice rules

Christmas, Black Friday, and summer sales mean onboarding large numbers of zero-hour workers quickly. The temptation is to sort out compliance later and just get people on the shop floor. That's exactly how problems start.

Plan your rota publication timelines in advance so you meet notice requirements even during busy periods. Pay attention to seasonal workers who might hit the 12-week reference period during a long peak. A Christmas temp who starts in October reaches 12 weeks in late December, right in the middle of your busiest trading period.

Use demand forecasting to publish rotas earlier and reduce last-minute changes. The better your forecast, the fewer shifts you'll need to cancel or amend at short notice.

Managing variable footfall across multiple locations

Retail is growing outside London. The Big Shift Report 2026 found that the North West added 14,000 retail shift work roles, followed by the South West with 11,000 and the South East with 10,000. Multi-location scheduling is becoming more common, and it adds a layer of complexity.

Moving a zero-hour worker between locations counts as a shift change, which requires notice. Each store may have different footfall patterns, so centralised scheduling helps you maintain consistency across sites. Tools like shift swapping make it easier for workers to pick up shifts at nearby locations without managers needing to rearrange rotas manually.

You also need to track hours across all locations (not just per site) for the guaranteed-hours threshold. A worker doing two shifts at one store and three at another is accumulating hours toward the same 12-week reference period.

Deputy's multi-location rota management lets you see hours across sites in one place, so you're not piecing together data from separate spreadsheets.

Scheduling younger workers with additional protections

Gen Z makes up the largest share of retail shift workers at 44%, and many are on zero-hour contracts. Workers under 18 have additional restrictions on working hours, rest breaks, and night work under UK employment law.

Your rota system needs to account for both zero-hour contract compliance and young worker protections at the same time. That means configuring different rules for different worker types, not applying a one-size-fits-all rota.

Deputy lets you set configurable compliance rules by worker type, so your rotas reflect the specific protections that apply to younger team members alongside the ERA 2025 requirements.

What non-compliance actually costs your business

The financial exposure from poor zero-hour scheduling is real and measurable. CIPD research on zero-hours contracts found that about half of employers using zero-hours contracts provide no compensation for short-notice shift cancellations, a practice the ERA 2025 is designed to eliminate.

Short-notice cancellation compensation is the most immediate cost. Every shift you cancel inside the notice window now comes with a payment obligation, subject to final regulatory guidance on the exact amounts. If your business regularly cancels shifts based on footfall, those costs will add up quickly.

Tribunal claims are the next tier of risk. Workers who aren't offered guaranteed hours after the reference period, or who don't receive reasonable notice, can bring claims. The legal costs, management time, and potential payouts make this a risk worth taking seriously.

Reputational damage hits harder in a tight labour market. With retail employment declining by four percent, you can't afford to lose workers (or potential hires) over a reputation for poor scheduling practices. Word travels fast, especially among younger workers who share experiences online.

The compounding effect is what makes this particularly costly. Poor scheduling drives higher turnover, which increases recruitment and training costs, which eats into margins that are already under pressure.

Compare that to the cost of implementing a proper scheduling process. A structured workflow with the right tools costs a fraction of what non-compliance will run you in cancellation payments, tribunal fees, and lost talent.

How scheduling software helps you meet the new rules

Managing compliance manually on spreadsheets means relying on human memory for audit trails, notice-period tracking, and hours calculations. That's where scheduling software makes a practical difference.

Automated shift documentation. A scheduling platform creates a timestamped record of every shift published, accepted, declined, or changed. That's your audit trail, built automatically as part of your normal rota workflow.

Notice-period flagging. Configurable rules can flag or prevent changes inside your defined notice window. Instead of relying on managers to remember the policy, the system catches it for you.

Hours-threshold monitoring. Track cumulative hours for each worker and surface alerts when they approach the guaranteed-hours reference period. No more manual spreadsheet checks.

Cancellation tracking and reporting. See patterns in cancellations across locations, managers, and time periods. This helps you identify forecasting problems before they become compliance problems.

AI-driven demand forecasting. Better forecasting means fewer last-minute changes, which reduces both cancellation costs and compliance risk. When your rota is built on accurate demand data, you're less likely to need to cancel shifts. Learn more about how AI demand forecasting is reshaping workforce planning.

Regulatory transparency. AI-driven workforce management systems are increasingly being examined under the UK AI Regulation White Paper and existing ICO guidance. Deputy takes this seriously, with transparent scheduling algorithms that you can audit and explain.

"On Deputy you can cap people's work to 40 hours a week and make sure everybody gets at least some sort of a break during the week. But with the previous process it was all manual [and] time consuming," says Wasib Awan, Box Office Manager at Winter Wonderland Hyde Park.

That shift from manual to system-supported scheduling is exactly what the ERA 2025 demands. You still own compliance, and with the right tools you're not doing it blind.

FAQs

What are the rules for zero-hour contracts in the UK under the Employment Rights Act 2025?

The ERA 2025 introduces three key provisions affecting zero-hour contracts: the right to request guaranteed hours after approximately 12 weeks, reasonable shift notice requirements, and compensation for short-notice cancellations. These provisions are expected to take effect from 2027, subject to final regulatory guidance. You can read the full text on legislation.gov.uk. Deputy's scheduling tools help you track hours thresholds and manage notice periods so you can prepare for these changes now.

Can a zero-hour contract worker say no to a shift?

Yes, workers on zero-hour contracts have no obligation to accept any shift offered to them. This is a fundamental principle of zero-hour arrangements, and the ERA 2025 reinforces worker choice by strengthening protections around shift offers and cancellations. Deputy logs shift offers and responses automatically, so you have a clear record of what was offered and how each worker responded.

How much notice do I need to give zero-hour workers for shifts in the UK?

Under the ERA 2025, you must give "reasonable notice" when scheduling, changing, or cancelling shifts for zero-hour workers. The exact notice periods will be set by secondary legislation, but the principle is that notice should be proportional to shift length. Set your own notice windows now (for example, 48 to 72 hours) so you're prepared when the regulations take effect. Deputy's rota tools let you configure notice-period rules and flag changes that fall inside your defined window.

What is the guaranteed-hours rule for zero-hour contracts?

The ERA 2025 gives zero-hour workers the right to request a guaranteed-hours contract after working for approximately 12 weeks. As the employer, you need to track cumulative hours and respond to requests within a documented process. You can accept, offer an alternative, or decline with a valid reason. Deputy tracks hours across shifts and locations, helping you see when workers are approaching the threshold.

How does Deputy help with zero-hour contract scheduling in the UK?

Deputy helps UK retailers schedule zero-hour workers compliantly by creating timestamped shift documentation, tracking hours thresholds, and surfacing potential notice-period issues. Key capabilities include timestamped rota publication, configurable compliance rules, AI-powered demand forecasting to reduce last-minute changes, and multi-location scheduling with centralised hours tracking. Try Deputy for free to see how it supports your rota management.

Do I have to pay a zero-hour worker if I cancel their shift?

Under the ERA 2025, if you cancel or curtail a shift without giving reasonable notice, the worker is entitled to compensation. The compensation is proportional, and the exact mechanism is subject to secondary legislation. The simplest way to avoid this cost is to improve your forecasting and rota planning so cancellations are rare. Deputy's demand forecasting helps you build more accurate rotas, reducing the need for last-minute changes.
