Part-time worker holiday entitlement UK

Part-time workers in the UK are entitled to paid holiday pro-rata based on days worked per week — the same statutory formula that gives full-time colleagues 28 days a year gives a 3-day-a-week worker 16.8 days. Bank holidays are typically pro-rated too, to avoid indirect discrimination against workers whose non-working days rarely fall on Mondays. This guide covers the calculation formula, bank holiday treatment, mid-year starters + leavers, and how to handle irregular part-time schedules where hours vary week-to-week.

Statutory pro-rata

Days per week × 5.6 = annual entitlement

Days/week Statutory days Statutory hours (8h/day)
1 5.6 44.8
2 11.2 89.6
3 16.8 134.4
4 22.4 179.2
5 28.0 224.0

Bank holidays

For fairness with full-time colleagues:

Standard 8 UK bank holidays pro-rata: - 5-day FT: 8 bank holidays - 4-day PT: 6.4 (round to 6 or 7) - 3-day PT: 4.8 (round to 5) - 2-day PT: 3.2 (round to 3) - 1-day PT: 1.6 (round to 2)

Employer approaches vary. Non-discrimination requirement means pro-rata treatment expected.

Worked example — 3-day-a-week

Full-time colleagues: 20 annual + 8 bank = 28 total 3-day PT: (20 × 0.6 = 12 annual) + (8 × 0.6 = 4.8 ≈ 5 bank) = 17 total

If bank holiday falls on non-working day, gets added to annual leave allowance instead.

Irregular part-time hours

Since April 2024: - 12.07% accrual method: hours worked × 12.07% = holiday hours - Rolled-up holiday pay: hourly rate + 12.07% uplift; worker takes unpaid holiday

Term-time only workers

Historic Harpur Trust v Brazel ruling: term-time workers get full 5.6 weeks based on average weekly pay across term (not pro-rated for weeks off).

2024 change: term-time + part-year workers now covered by 12.07% method going forward.

In short

Part-time holiday: days/week × 5.6 for regular schedules. Bank holidays pro-rata for fairness. Irregular schedules: 12.07% method since 2024.

Frequently asked questions

What if I work variable days each week?

Use 12.07% accrual method. Every hour worked accrues 12.07% as paid holiday.

Do I get bank holidays if I don't work Mondays?

Employer should credit pro-rata bank holiday days to your annual leave for fairness (non-discrimination).

How is holiday pay calculated for part-time?

Same as full-time: one week's normal pay per week of holiday. Or hourly average over 52 weeks.

What if I increase from 3 to 5 days a week mid-year?

Recalculate entitlement pro-rata for months at each pattern. Common approach: 3 days × 3 months + 5 days × 9 months prorated.

Am I entitled to holiday if I only work occasional days?

Yes — 12.07% of hours worked accrues as paid holiday. Or receive rolled-up 12.07% uplift instead.
