Zero hours contract workers are entitled to statutory annual leave of 5.6 weeks (28 days for a full-time worker) accrued based on hours worked.

Key Takeaways

  • Zero hours workers accrue holiday based on hours worked
  • The 12-week average calculation determines holiday pay
  • Workers can request leave at any time, subject to notice requirements
  • Employers cannot include holiday pay in hourly rates (rolled-up holiday pay is banned)
  • Accurate time recording is essential for compliance

How Zero Hours Holiday Entitlement Works

Zero hours contract workers accrue holiday in a unique way compared to fixed-hour employees:

Accrual Method

Holiday accrues at a rate of 12.07% of hours worked. This is calculated as:

  • 5.6 weeks holiday ÷ (52 weeks - 5.6 weeks) = 12.07%

Example Calculation

If a zero hours worker works 20 hours in a week:

  • 20 hours × 12.07% = 2.41 hours holiday accrued

Holiday Pay Calculation

When a zero hours worker takes holiday, their pay is based on their average weekly earnings over the previous 52 weeks:

  1. Calculate total earnings — Sum of gross pay over 52 weeks
  2. Divide by weeks worked — Only count weeks where earnings were received
  3. Divide by expected working days — Determine daily rate
  4. Multiply by days taken — Total holiday pay owed

52-Week Reference Period

  • Use the previous 52 weeks where pay was received
  • If fewer than 52 weeks worked, use the available weeks
  • Weeks with no pay do not count in the average calculation

Key Rules for Employers

What Employers Must Do

  • Record all hours worked — Accurate time tracking is essential
  • Calculate holiday accrual — Track 12.07% accrual on all hours
  • Pay correct holiday pay — Based on 52-week average
  • Allow holiday requests — Workers can request leave at any time
  • Provide itemized payslips — Show holiday pay separately

What Employers Cannot Do

  • Rolled-up holiday pay — Cannot include holiday pay in hourly rate
  • Refuse all leave requests — Must allow reasonable holiday requests
  • Ignore accrued leave — Cannot let holiday entitlement expire
  • Use incorrect calculation — Must use the 52-week reference period

Notice Requirements

Zero hours workers must give notice to take holiday:

  • Minimum notice — Twice the length of the leave period
  • Employer refusal — Can be refused with equivalent notice
  • Bank holidays — Can be required to work bank holidays if contractual

Common Compliance Issues

Issue Risk Solution
No time recording Cannot prove compliance Implement time tracking system
Incorrect accrual calculation Underpayment claims Use 12.07% formula correctly
Wrong reference period Holiday pay disputes Use 52-week average
Rolled-up holiday pay Illegal practice Separate holiday pay from hourly rate
