Rota laws in the UK: what you can and cannot schedule
There is no single "rota law". What constrains a rota is the Working Time Regulations 1998 — a small set of limits on hours, breaks and rest that are easy to state and surprisingly easy to breach with an ordinary shift swap.

Key takeaways
- Working time is capped at a 48-hour average, normally over a 17-week reference period — not 48 hours in any single week
- A worker can opt out of the 48-hour limit, but only in writing, only voluntarily, and they can withdraw it
- A shift longer than 6 hours carries a right to one uninterrupted 20-minute rest break, which does not have to be paid
- There must be 11 hours rest in each 24-hour period, and 24 hours off each week or 48 hours every two weeks — a genuine shift changeover is excepted, but compensatory rest is owed
- There is no general statutory minimum notice for a shift today — that changes under the Employment Rights Act 2025, expected in 2027
The 48-hour week is an average, not a ceiling
Working time is capped at 48 hours a week on average, normally over 17 weeks. The averaging is the part people miss in both directions: a single 60-hour week is not automatically a breach, and a run of 50-hour weeks quietly is.
A worker can opt out, but the agreement has to be in writing and genuinely voluntary — it cannot be a condition of being offered the job or of getting shifts. They can withdraw it, giving notice as agreed (or up to three months if nothing was agreed). Keep the signed opt-outs somewhere you can actually find them.
Under-18s cannot opt out
Workers under 18 are limited to 8 hours a day and 40 hours a week, with no averaging and no opt-out. If you employ 16 and 17 year olds in a weekend trading pattern, this is the limit to design the rota around.
Breaks and rest
| Entitlement | The rule |
|---|---|
| In-work rest break | One uninterrupted 20 minutes where the day is longer than 6 hours. Need not be paid. |
| Daily rest | 11 hours in each 24 hours (shift changeover excepted — compensatory rest owed) |
| Weekly rest | 24 hours off each week, or 48 hours off every two weeks |
| Night work | Average 8 hours in each 24, plus a free health assessment |
The 11-hour rule is where rotas fail in practice. A close-then-open — 11pm finish, 7am start — leaves 8 hours and is a breach, however willing the person is. It is worth checking every changeover on a published rota, and especially every swap agreed after publication.
An unpaid break also has to be a genuine break. Someone required to stay at the till, watch the door or answer the phone is working, and that time must be paid at least at the National Minimum Wage. Breaks that exist on paper but not in practice are one of the most common causes of underpayment.
How much notice you owe — and what is coming
This is the question employers ask most and the one UK law is currently quietest on. There is no general statutory minimum notice for a shift. Whatever the contract says, applied consistently, is the standard.
That is changing. The Employment Rights Act 2025 introduces a right to reasonable notice of shifts and to a payment where a shift is cancelled, moved or cut short at short notice — expected in 2027 and subject to consultation. Our guide to the shift-related changes sets out what is coming and why it makes the rota a compliance record rather than just a plan.
Keeping adequate records
Employers must keep records adequate to show the 48-hour limit is being complied with. In practice that means being able to reconstruct, months later, how many hours someone actually worked across a 17-week window — which a rota alone cannot do, because it records what was planned.
Clock-in and clock-out records answer that question directly, and rota software can flag an 11-hour breach before the rota is published rather than after someone raises it. If you are still planning in a spreadsheet, our free UK rota templates carry the working time limits on the instructions tab — the weekly grid is the usual starting point. Two related pieces sit alongside this one: changing a rota covers notice and swaps once it is published, and timesheets and working time records covers proving the limits were met.

This guide summarises the Working Time Regulations 1998 as they generally apply and is not legal advice. Exemptions, collective agreements and sector-specific rules can change the position.

It does not constitute legal, HR, or professional advice and should not be relied on as a substitute for advice specific to your business, workforce, or circumstances.
UK rota law questions
- Working time is limited to 48 hours a week on average, normally averaged over a 17-week reference period. That means a 60-hour week is not automatically unlawful — what matters is the average across the period. Workers under 18 are different: they cannot work more than 8 hours a day or 40 hours a week, and cannot opt out.
- A worker can agree to work more than the 48-hour average, but the agreement must be in writing and genuinely voluntary. It cannot be a condition of getting the job, and a worker can withdraw it. Keep a record of who has opted out — in a dispute the burden is on the employer to produce it.
- The limit does not apply to some categories, including roles needing 24-hour staffing, the armed forces, emergency services and police, security and surveillance work, domestic service in a private household, sea and inland-waterway work, and managing executives with genuine control over their own hours. "24-hour staffing" is narrower than it sounds — it does not simply mean any business that trades around the clock.
- No. Rest breaks, annual leave, sick leave and maternity or paternity leave are not working time, and neither is commuting between home and the usual workplace. Travel between assignments during the working day is. See our minimum wage guide for what counts as working time for pay purposes, which is a related but separate test.
