Variable hours make a fixed allowance meaningless.
A standard holiday allowance assumes a standard week. For someone on a zero hours or casual contract, there is no standard week. One month they work 20 hours, the next 120, and the next nothing at all.
For leave years starting on or after 1 April 2024, irregular-hours and part-year workers build up holiday at 12.07% of the hours they work in each pay period. That is simple on paper, but it means a running calculation for every person, every pay period.
Leavely does the sum. You record the hours, and the balance follows.
What the law says, in brief
The main points behind the 12.07% basis. GOV.UK sets out the full rules on holiday entitlement.
Leave years from 1 April 2024
The 12.07% accrual method applies to irregular-hours and part-year workers for leave years starting on or after 1 April 2024.
Who it covers
Irregular-hours workers, whose paid hours are wholly or mostly variable, and part-year workers, who work only part of the year with periods of at least a week without work or pay.
12.07% of hours worked
Holiday accrues at 12.07% of the hours worked in each pay period. 12.07% is 5.6 weeks divided by the 46.4 weeks worked in a year.
Bank holidays are included
Because the rate is based on the full 5.6 weeks, it already includes bank holidays. There is no separate bank holiday allowance on top.
Rolled-up holiday pay is allowed
For these workers, employers may pay an extra 12.07% of pay each pay period instead, shown separately on the payslip.
12.07% holiday that keeps itself up to date
Replace the spreadsheet of hours and percentages with a balance that updates each pay period.
A 12.07% holiday basis per employee
Set "Irregular hours / part-year (12.07%)" as the holiday basis for the people it applies to. Everyone else stays on your usual leave policies.
Hours per pay period
Managers record the hours each person worked in each pay period. Their holiday balance is 12.07% of the hours worked in the leave year.
Import from clock-ins
If you use clock-in in Leavely, managers can import hours from completed clock-ins rather than typing them in.
Hours or days
Show the balance in hours, or convert it to days using the person's usual hours per day.
No double-counted bank holidays
Bank holidays are already inside the 12.07%, so there is no separate bank holiday deduction for people on this basis.
Clear for employees
Employees see the hours recorded for them and the holiday they have earned on their profile.
