How holiday pay is worked out for irregular hours
If your hours change from week to week, or you only work part of the year, your holiday builds up as you work rather than as a fixed number of days. It accrues at 12.07% of the hours you work.
Worked example. Work 100 hours and you accrue 12.07 hours of paid holiday. At £12/hour that holiday is worth £144.84.
Where 12.07% comes from
Statutory holiday is 5.6 weeks. That leaves 46.4 weeks actually worked in a year. Dividing one by the other gives 5.6 / 46.4 = 12.07%. For leave years starting on or after 1 April 2024, employers can pay this as rolled-up holiday pay for irregular-hours and part-year workers.
Fixed regular hours
If you work the same hours every week, this method does not apply. Your holiday is a fixed entitlement instead. Use the holiday entitlement calculator to work out your days.
