Why 12.07%?

UK statutory annual leave is 5.6 weeks a year. A year has 52.14 weeks, so non-holiday working weeks equal 52.14 minus 5.6 = 46.4 weeks. Dividing 5.6 weeks' holiday by those 46.4 working weeks gives 12.07% — the proportion of hours worked that should accrue as paid holiday when hours vary too much to use a fixed weekly entitlement.

Who does this apply to?

The 12.07% rolled-up method is available for irregular-hours workers and part-year workers (permanent staff who only work part of the year, such as term-time-only roles), for leave years starting on or after 1 April 2024. Rolled-up holiday pay must be paid alongside normal wages and shown as a separate, clearly itemised amount on the payslip.
