Zero-hours contracts offer flexibility for both employers and workers. They allow businesses to scale staffing up or down depending on demand, and give workers more control over when they work. But when it comes to payroll, zero-hours contracts can create added complexity.
From calculating holiday pay to managing fluctuating hours, it is important to understand your responsibilities and ensure your payroll is set up correctly.
At Lucas White Payroll Services Ltd, we help businesses across the UK manage payroll for zero-hours staff with accuracy, clarity, and compliance. Here is what you need to know.
1. Workers on Zero-Hours Still Have Employment Rights
Zero-hours staff may not have guaranteed hours, but they are still entitled to basic employment rights. That includes:
- National Minimum Wage
- Holiday pay
- Payslips
- Protection from discrimination
- Statutory sick pay (if eligible)
You must also follow proper procedures for onboarding, record keeping, and reporting to HMRC.
2. Holiday Pay Must Be Calculated Correctly
Holiday pay is one of the most common areas where businesses make mistakes with zero-hours workers. These staff do not usually work fixed hours, so you must calculate their holiday pay based on average earnings over the previous 52 paid weeks.
If workers have not been with you that long, use the number of paid weeks they have worked. It is important not to guess or round the figure — accurate tracking of hours and pay is essential.
3. PAYE Still Applies
Even if a worker is only on a few shifts a month, they still need to be included in your PAYE scheme. That means you must deduct Income Tax and National Insurance as required, submit real-time information (RTI) to HMRC, and issue payslips.
If you are using software, it must handle variable hours and calculate deductions accurately each pay period. A managed payroll service can do this for you, reducing the risk of errors.
4. Clear Record Keeping Is Essential
Zero-hours contracts often involve irregular working patterns. Without a reliable system in place, it is easy to lose track of hours worked, breaks taken, and entitlements built up over time.
You need to keep detailed records of:
- Hours worked
- Pay rates for different tasks or shifts
- Holiday accrued and taken
- Any deductions or bonuses
This helps avoid disputes and ensures you can respond confidently if HMRC or an employee asks for clarification.
5. Contracts Must Be Clear
The contract should explain the nature of the zero-hours arrangement, including:
- That hours are not guaranteed
- Pay rates and frequency
- Holiday entitlement and how it will be calculated
- How shifts are offered and accepted
Clarity in the contract helps prevent misunderstandings and sets expectations from the start.
6. Consider Fair Scheduling Practices
While zero-hours contracts are legal, unfair practices can cause problems. For example, if a worker is regularly working the same number of hours each week, they may be entitled to a more stable contract.
It is also good practice to give as much notice as possible when offering shifts, and to avoid cancelling work at the last minute unless absolutely necessary.
