How to Pay Annual Leave for Zero-Hours Staff

Zero-hours workers are entitled to paid annual leave under UK law. This guide explains how to calculate holiday pay for irregular hours, using either the 12.07% accrual method or the average weekly pay method , and how FlowRota helps automate the process.

Method 1: 12.07% Holiday Accrual

Each time a zero-hours worker works hours, you accrue holiday at 12.07% of those hours. This percentage represents the statutory 5.6 weeks of holiday over a year.

Example:

• If a worker works 100 hours in a month, 100 × 0.1207 = 12.07 hours accrued.
• Accrued hours are converted to pay using the worker’s hourly rate when leave is taken.

Rolled-up holiday pay (adding 12.07% to each pay) is also allowed, but workers still retain the right to take leave as time off.

Method 2: Average Weekly Pay

Holiday pay can also be calculated using the worker’s average weekly pay over the last 52 paid weeks (excluding zero-pay weeks). This method ensures pay reflects variable hours and overtime.

Example:

• Average weekly pay = Total pay over 52 weeks ÷ number of paid weeks.
• If the average weekly pay is £400, one week of holiday = £400, and full statutory entitlement (5.6 weeks) = 400 × 5.6 = £2,240.

Paying Holiday on Termination

If a worker leaves with untaken statutory holiday, you must pay it in lieu in their final pay, calculated using the same method (12.07% accrual or average pay). Keep clear records for compliance.
