How Part-Time Holiday Entitlement Works
All employees in the UK, whether full-time or part-time, are entitled to 5.6 weeks of statutory paid annual leave. For part-time workers, this entitlement is calculated proportionally based on their working hours or days.
Key Point: Part-time employees receive the same number of weeks of holiday as full-time employees, but the actual days or hours will be proportional to their working pattern.
Statutory Holiday Calculation Methods
By Days: 5.6 weeks × Days worked per week = Annual leave entitlement (days)
By Hours: 5.6 weeks × Hours worked per week = Annual leave entitlement (hours)
Examples of Statutory Entitlement by Days
| Days Worked per Week | Calculation | Annual Entitlement |
|---|---|---|
| 1 day | 5.6 × 1 | 5.6 days |
| 2 days | 5.6 × 2 | 11.2 days |
| 3 days | 5.6 × 3 | 16.8 days |
| 4 days | 5.6 × 4 | 22.4 days |
Examples of Statutory Entitlement by Hours
| Hours Worked per Week | Calculation | Annual Entitlement |
|---|---|---|
| 10 hours | 5.6 × 10 | 56 hours |
| 20 hours | 5.6 × 20 | 112 hours |
| 30 hours | 5.6 × 30 | 168 hours |
| 35 hours | 5.6 × 35 | 196 hours |
Enhanced Holiday Entitlement
Many employers offer more than the statutory minimum. When calculating enhanced entitlement for part-time workers, the same proportional principle applies.
Enhanced Entitlement Formula (Days)
(Full-time annual leave ÷ 5) × Days worked per week = Part-time entitlement
Enhanced Entitlement Formula (Hours)
(Full-time hours entitlement ÷ Full-time weekly hours) × Part-time weekly hours = Part-time entitlement
Important: Holiday entitlement cannot be rounded down by law. Employers may round up to the nearest half-day if preferred, but must never round down.
Bank Holidays and Part-Time Workers
Bank holidays can be included in the statutory 5.6 weeks or offered as additional leave. The treatment depends on the employment contract and whether the part-time worker normally works on bank holiday dates.
Key Considerations
- Most bank holidays fall on Mondays, affecting Monday workers more than others
- If a part-time worker is scheduled to work on a bank holiday and gets it off, their holiday entitlement reduces by one day
- If they don’t normally work on bank holiday dates, it doesn’t affect their entitlement
- The fairest approach is to calculate total leave inclusively (statutory + bank holidays)
Frequently Asked Questions
Do part-time workers get the same holiday entitlement as full-time workers?
Part-time workers receive the same number of weeks (5.6 weeks statutory minimum) but the actual days or hours are proportional to their working pattern. They cannot be treated less favourably than full-time workers.
How do I calculate holiday pay for irregular hours?
For workers with irregular hours, calculate the average hours worked over the previous 12 weeks. Multiply this average by 5.6 weeks to determine annual entitlement. Holiday pay should be based on average weekly earnings.
Can employers round down holiday entitlement?
No, by law employers cannot round down holiday entitlement. If the calculation results in 22.4 days, it must remain at least 22.4 days. Employers may choose to round up to 22.5 or 23 days if they wish.
What happens if someone works more than 5 days per week?
Statutory leave is capped at 28 days regardless of working pattern. Someone working 6 or 7 days per week would still only be entitled to 28 days statutory leave, unless their employer offers enhanced entitlement.
How do bank holidays affect part-time holiday calculations?
Bank holidays only affect entitlement if the part-time worker is normally scheduled to work on those days. The fairest approach is to calculate total annual leave (including bank holidays) and apply pro-rata calculations to this total amount.
When do part-time workers start accruing holiday?
Holiday accrual begins from the first day of employment, including during probationary periods. Workers build up holiday entitlement throughout the year, typically accruing 1/12th of their annual entitlement each month.
Legal Requirements and Best Practices
Employers must comply with statutory minimums whilst many choose to offer enhanced packages to attract and retain talent.
Statutory Requirements
- Minimum 5.6 weeks paid annual leave for all workers
- Pro-rata calculations for part-time employees
- Cannot round down entitlement calculations
- Holiday pay at normal rate for first 4 weeks of statutory entitlement
Best Practice Recommendations
- Clearly communicate holiday policies in employment contracts
- Use consistent calculation methods across all part-time roles
- Consider offering enhanced entitlement above statutory minimums
- Maintain accurate records of holiday accrual and usage
- Review policies annually to remain competitive
Professional Tip: Many employers find it simpler to calculate all holiday entitlement inclusively, treating bank holidays and annual leave as one total allocation rather than separate calculations.
