Understanding annual leave entitlement
- Statutory entitlement: A full time employee working 5 days a week is entitled to 5.6 weeks (28 days) of paid leave per year. This may include public holidays and UK bank holidays.
- Part time workers: Holiday allowance is calculated on a pro rata basis depending on the number of days a week or hours worked.
- Joining or leaving mid-year: When an employee works only part of a leave year, their annual leave entitlement is pro rata holiday entitlement based on the start date or leaving date.
- Carry-over of unused holiday: Many employers allow unused holiday days to be carried over. Rules differ, but statutory minimum requirements apply.
- Irregular hours and zero hours workers: Holiday entitlement is calculated based on average hours worked per week over a reference period.

FAQs — Calculating holiday entitlement
How do you calculate pro rata holiday entitlement in the UK?
Pro rata holiday entitlement is calculated based on the number of days a week or hours an employee works compared with a full time worker. Our pro rata holiday calculator makes it easy to see how many days of holiday an employee is entitled to.
What happens to annual leave entitlement if an employee joins partway through the year?
If an employee works only part of a leave year, their entitlement is calculated on a pro rata basis from the start date until the end date of employment. This ensures the employee is treated fairly and receives the same amount of paid leave as full time workers.
Are bank holidays included in statutory annual leave entitlement?
Yes. The statutory minimum of 5.6 weeks (28 days) annual holiday entitlement can include UK bank holidays and public holidays. Employers may decide whether these are included in the holiday allowance or given in addition.
Can unused holiday allowance be carried over into the next year?
Many employers allow unused holiday to roll over into the next leave year. This is calculated based on statutory entitlement rules and may vary — always check your employee handbook.
What is the maximum statutory holiday entitlement per year?
The maximum statutory entitlement is 28 days (5.6 weeks) for full time employees. Even if there are more UK bank holidays in a holiday year, statutory leave does not exceed 28 days paid time off.
How much annual leave are part time employees entitled to?
Part time workers have their annual leave entitlement calculated on a pro rata basis. For example, if an employee works 3 days a week, their entitlement is 3/5ths of 28 days. Use our annual leave entitlement calculator to work this out in seconds.
How is holiday pay calculated for zero hours workers or irregular hours staff?
Holiday pay and annual entitlement for zero hours workers is calculated based on average hours worked over the past 52 weeks. This ensures employees receive paid time off that reflects their working patterns.
