UK Working Time Regulations & Statutory Leave Guide 2026
Complete guide to UK working-time and statutory annual-leave rules, including the 48-hour average working week, opt-out agreements, daily and weekly rest, night-worker limits, 5.6 weeks' paid holiday, holiday pay, irregular-hours workers, part-year workers and young worker protections.
1. UK Working Time Regulations 1998: What They Cover
The Working Time Regulations 1998 establish statutory protections covering working hours, rest periods, night work and paid annual leave for covered workers. The rules are subject to important exceptions and special arrangements for certain sectors and categories of worker. For most adult workers, the central rule is that average working time should not exceed 48 hours per week unless the worker voluntarily agrees to opt out. The normal reference period for calculating the average is 17 weeks.
2. The 48-Hour Average Working Week
Most adult workers cannot be required to work more than an average of 48 hours per week over the applicable reference period. This is an average limit rather than an absolute prohibition on working more than 48 hours in an individual week. For most workers the normal reference period is 17 weeks. Certain collective or workforce agreements can allow a longer reference period, subject to the statutory rules.
| Rule | Standard Position | Important Qualification |
|---|---|---|
| Average weekly limit | 48 hours | Normally averaged over 17 weeks |
| Individual week | Can exceed 48 hours | The statutory test is normally based on the average over the reference period |
| Opt-out | Permitted for adult workers | Must be voluntary and in writing |
| Reference period | Normally 17 weeks | Can be longer in certain circumstances |
3. 48-Hour Opt-Out Agreement
An adult worker can voluntarily agree in writing to work more than the average 48-hour weekly limit. An employer cannot force a worker to sign an opt-out agreement as a condition of employment where the statutory protection applies. The agreement can be limited to a particular period or can be open-ended. The worker can cancel the opt-out by giving the notice specified in the agreement, subject to the statutory minimum and maximum notice requirements.
4. What Counts as Working Time
Working time generally includes time when a worker is working, carrying out duties for the employer and is at the employer's disposal. Whether particular periods such as training, travel between work locations, standby or on-call time count can depend on the circumstances and applicable case law. The working-time calculation is not necessarily identical to the hours for which a worker receives National Minimum Wage. Separate statutory tests apply.
5. Daily Rest: 11 Consecutive Hours
Adult workers generally have the right to at least 11 consecutive hours of rest in each 24-hour period. This means that where a worker finishes work at 8pm, the standard rule would generally require the next working period not to begin before 7am. There are exceptions for certain activities and working patterns. Where a normal rest entitlement cannot be provided, compensatory rest may be required.
6. Rest Break During the Working Day
Adult workers generally have a statutory right to an uninterrupted 20-minute rest break when their daily working time is more than 6 hours. The break does not automatically have to be paid. The worker should normally be able to take the break away from their workstation if they choose, and it should normally be taken during the working period rather than simply being added to the beginning or end of the day.
| Worker | Working Time Trigger | Minimum Break |
|---|---|---|
| Adult worker | More than 6 hours daily working time | 20 uninterrupted minutes |
| Young worker | More than 4.5 hours | 30 uninterrupted minutes |
7. Weekly Rest Entitlement
Adult workers generally have a right to either an uninterrupted 24-hour period of rest in each 7-day period or, in specified arrangements, two uninterrupted 24-hour periods in each 14-day period. The weekly-rest entitlement is separate from the 11-hour daily-rest entitlement. Special arrangements and exceptions can apply in particular occupations.
8. Night Workers and the 8-Hour Average Limit
A worker is generally a night worker if they regularly work at least 3 hours during the night period. The default night period is 11pm to 6am, although a different 7-hour period can be agreed in writing provided it includes midnight to 5am. Night workers normally cannot work more than an average of 8 hours in each 24-hour period over the applicable reference period. The normal reference period is 17 weeks, although longer periods can apply in specified circumstances. Workers cannot opt out of the statutory night-work limit.
| Night Work Rule | Standard Requirement |
|---|---|
| Night period | Normally 11pm to 6am |
| Alternative night period | 7 hours including midnight to 5am, agreed in writing |
| Night-worker threshold | Normally at least 3 hours during the night period |
| Maximum average night work | 8 hours in each 24-hour period |
| Normal reference period | 17 weeks |
| Opt-out | Not permitted |
9. Night Workers: Health Assessments and Special Hazards
Employers must offer night workers the opportunity of a free health assessment before they start night work and at regular intervals where required by the statutory rules. Night workers who perform work involving special hazards or heavy physical or mental strain can be subject to a stricter limit: they must not work more than 8 hours in any 24-hour period rather than merely averaging 8 hours over a reference period.
10. Statutory Annual Leave: 5.6 Weeks
Most workers are entitled to at least 5.6 weeks of paid annual leave each leave year. For a worker who normally works 5 days per week, this is 28 days. The statutory entitlement is capped at 28 days even for workers who normally work more than 5 days per week. Employers can provide additional contractual holiday above the statutory minimum.
| Working Pattern | Minimum Statutory Holiday |
|---|---|
| 5 days per week | 28 days |
| 3 days per week | 16.8 days |
| Part-time regular hours | 5.6 weeks, pro-rated to the working pattern |
| 6 or 7 days per week | Statutory entitlement capped at 28 days |
11. Are Bank Holidays Included in the 28 Days?
There is no separate statutory entitlement to paid bank holidays in addition to the 5.6-week minimum. An employer can include bank holidays within the worker's statutory 5.6 weeks or provide bank holidays in addition to the statutory minimum under the employment contract. For example, an employer can state that a worker receives 20 days plus 8 bank holidays, giving a total of 28 statutory days.
12. Holiday Entitlement for Part-Time Workers
Part-time workers are entitled to the same 5.6 weeks of statutory annual leave as full-time workers, but the entitlement is calculated proportionately according to their working pattern. For example, someone working 3 regular days per week would normally receive 16.8 days of statutory leave (3 × 5.6). Their entitlement in hours can be calculated based on their contractual working pattern.
13. Irregular-Hours and Part-Year Workers
For leave years beginning on or after 1 April 2024, specific statutory accrual rules apply to irregular-hours and part-year workers. Their statutory leave entitlement is generally accrued at 12.07% of the hours worked in each pay period, subject to the statutory rules and the 5.6-week maximum. This method is different from simply giving every zero-hours worker 5.6 weeks based on an assumed weekly schedule.
| Hours Worked in Pay Period | 12.07% Accrual | Approximate Holiday Accrued |
|---|---|---|
| 30 hours | 30 × 12.07% | 3.621 hours |
| 50 hours | 50 × 12.07% | 6.035 hours |
| 100 hours | 100 × 12.07% | 12.07 hours |
14. Holiday Pay for Regular-Hours Workers
Workers are generally entitled to a week's pay for each week of statutory leave. The precise calculation depends on the worker's hours and pay structure. For regular-hours workers with fixed pay, a week's holiday pay will normally equal the amount they would normally receive for a week's work. For workers with regular hours but variable pay, the calculation can require averaging relevant pay over the statutory reference period.
15. Holiday Pay for Irregular-Hours and Part-Year Workers
For irregular-hours and part-year workers, holiday pay is generally based on average pay over the previous 52 weeks in which the worker was paid, excluding weeks where no pay was received from the relevant reference calculation. The reference period can therefore reach further back than 52 calendar weeks when unpaid weeks are excluded, subject to the statutory maximum look-back rules.
16. Rolled-Up Holiday Pay
Rolled-up holiday pay is permitted for irregular-hours workers and part-year workers for leave years beginning on or after 1 April 2024, subject to the statutory rules. Where an employer uses rolled-up holiday pay, the holiday pay is normally calculated at 12.07% of the worker's total pay in the relevant pay period and should be paid as a separate identifiable amount at the same time as the worker's pay.
17. Carrying Annual Leave Forward
Whether annual leave can be carried forward depends on the contract and statutory circumstances. Employers can allow contractual carry-over, and statutory rules require or permit carry-over in certain situations. Workers unable to take leave because of family-related leave can carry over untaken statutory leave. Workers unable to take leave because of sickness can also carry forward specified statutory leave, subject to the applicable rules. Additional carry-over rights can arise where the employer failed to provide a reasonable opportunity to take leave, failed to inform the worker about the risk of losing it or failed to provide required holiday pay.
18. Annual Leave and Sickness
Workers continue to accrue statutory annual leave while they are off sick. If sickness prevents a worker from taking statutory leave, statutory carry-over rights can apply. A worker can also choose to take annual leave while they are off sick. Employers cannot normally require a worker to take annual leave instead of sick leave simply to avoid sickness absence rules.
19. Young Workers: Working Hours and Rest
Young workers aged 16 or 17 who are above school-leaving age receive additional working-time protection. They generally cannot work more than 8 hours a day or 40 hours a week. Young workers generally receive a 30-minute rest break when daily working time exceeds 4.5 hours, at least 12 consecutive hours of daily rest and two days of weekly rest. They cannot opt out of their statutory working-time limits.
| Protection | Young Worker Rule |
|---|---|
| Maximum daily working time | 8 hours |
| Maximum weekly working time | 40 hours |
| Rest break | 30 minutes when working more than 4.5 hours |
| Daily rest | Normally 12 consecutive hours |
| Weekly rest | Normally 2 days |
| 48-hour adult opt-out | Not permitted |
20. Exceptions to the Working Time Rules
The Working Time Regulations contain exceptions and special arrangements for certain occupations and working patterns. Examples can include emergency services, security and surveillance, armed forces, certain transport workers, domestic servants in private households and workers whose working time is not measured or predetermined and who control their own working time. Sector-specific working-time regimes can apply to drivers, seafarers, aviation workers and other categories. Employers should therefore not apply the general 48-hour rule without checking whether a sector-specific regime applies.
21. Employer Record-Keeping and Compliance
Employers should keep adequate records demonstrating compliance with working-time requirements. Records can include working hours, rest periods, night-work limits and relevant opt-out agreements. Annual-leave record requirements have also been strengthened. From 6 April 2026, employers must keep detailed annual-leave and holiday-pay records for at least 6 years from the date the records were made.
22. Practical Employer Working-Time Compliance Checklist
Employers should review working patterns, contracts, annual-leave policies and payroll processes to ensure they comply with the 2026 rules.
