Statutory holiday entitlement per the Working Time Regulations 1998 and GOV.UK guidance (gov.uk/holiday-entitlement-rights). Not legal advice.
The part-time holiday entitlement calculator works out your pro-rata annual leave as a UK part-time worker. Enter the number of days you work each week and see your statutory 5.6-week entitlement in days — with and without bank holidays counted separately.
Statutory pro-rata leave
UK law (the Working Time Regulations 1998) gives every worker a minimum of 5.6 weeks paid holiday per year. For a full-time 5-day worker that is 28 days. For part-time workers it scales proportionally:
So a worker doing 3 days a week gets 3 × 5.6 = 16.8 days. Employers usually round to the nearest half or whole day.
| Days/week | Statutory leave | Pro-rata BHs (E&W) | Choosable |
|---|---|---|---|
| 2 | 11.2 | 3.2 | 8.0 |
| 3 | 16.8 | 4.8 | 12.0 |
| 4 | 22.4 | 6.4 | 16.0 |
| 4.5 | 25.2 | 7.2 | 18.0 |
If your hours vary each week, holiday accrues at 12.07% of hours worked. For every 100 hours you work, you earn 12.07 hours of paid leave. Your employer can pay this as "rolled-up" holiday pay — adding 12.07% to every payslip. For the monetary value, use the holiday pay calculator.
The holiday pay calculator shows the cash value of your leave. The bank holiday pay calculator covers enhanced rates for working bank holidays. For your overall pay, try the pro-rata salary calculator.
UK law gives all workers a minimum of 5.6 weeks paid holiday per year. For a part-time worker doing 3 days a week, that is 3 times 5.6 equals 16.8 days. Your employer may round this up to 17 days. Bank holidays can be included in this total.
Multiply the number of days you work per week by 5.6. For example, 4 days per week times 5.6 equals 22.4 days of annual leave. If you work irregular hours, use total annual hours divided by 46.4 (52 weeks minus 5.6) to find your holiday hours.
Part-time workers have no automatic right to take specific bank holidays off. Bank holidays are included within the 5.6-week statutory entitlement. If a bank holiday falls on a day you work, your employer may give you the day off and count it from your leave, or require you to work it.
Yes. A full-time worker gets 28 days (5.6 weeks). The employer can include the 8 bank holidays within those 28 days, leaving 20 days of choosable leave. Or they can offer bank holidays on top, giving 28 plus 8 equals 36 days total. Check your contract.
For irregular-hours or zero-hours workers, holiday accrues at 12.07% of hours worked. For every 100 hours worked you earn 12.07 hours of paid leave. Your employer may use rolled-up holiday pay, adding 12.07% on top of every payment.
Yes. You continue to accrue your full statutory and contractual holiday entitlement throughout maternity, paternity and shared parental leave. Any untaken leave can usually be carried forward — check your employer's carry-over policy.
