Statutory Annual Leave Entitlement
Most workers who work a 5-day week must receive at least 28 days’ paid annual leave a year. This is the equivalent of 5.6 weeks of holiday.
Working part-time
Part-time workers are entitled to at least 5.6 weeks’ paid holiday, but this will amount to fewer than 28 days.
For example, if they work 3 days a week, they must get at least 16.8 days’ leave a year (3 × 5.6).
Here is the link to the Gov.uk website holiday calculator for you to work out a part-time worker’s leave.

Irregular hours
People working irregular hours (like shift workers or term-time workers) are entitled to paid time off for every hour they work.
Employers and employees may find it helpful to get an estimate of holiday entitlement by calculating leave based on days or hours worked in an average week.
You can use the link above to the Gov.uk holiday calculator.
Limits on statutory leave
Statutory paid holiday entitlement is limited to 28 days. For example, staff working 6 days a week are only entitled to 28 days’ paid holiday.
