FAQs (for common holiday pay questions)
How do you calculate holiday pay for zero-hours workers?
Typically, this is done by using a 52-week average of pay (excluding non-working weeks) or, for leave years starting on/after 1 April 2024, by applying the 12.07% accrual method for
irregular hours or part-year workers. The right method depends on your leave year and worker type.
What is rolled-up holiday pay and when can we use it?
From leave years starting 1 April 2024, rolled-up holiday pay can be used for irregular hours and part-year workers. It’s paid in each pay period and must be shown clearly as a separate
item on the payslip. It should not be used for workers with fixed hours.
Do we include overtime and commission?
Yes, if they are regular. Holiday pay should reflect an employee’s normal remuneration, which includes regular overtime and commission. We can help determine what counts as “regular” for your organisation.
What changed after Brazel v Harpur Trust?
The Supreme Court confirmed that certain part-year workers’ holiday cannot be calculated simply by applying a fixed percentage. Employers must ensure the calculation reflects statutory entitlement and is based on proper averaging.
