Holiday pay claims have surged in recent years, driven by evolving case law and new Working Time Regulations updates. If an employee or worker says they’ve been underpaid for annual leave, don’t panic - with a clear process and the right documentation, you can resolve issues quickly and prevent repeat claims.
In this guide, we’ll explain what a holiday pay claim is from an employer’s perspective, the legal rules that apply under UK law, how to calculate holiday pay correctly (including overtime and irregular hours), and a step-by-step approach to handling claims and reducing your risk going forward.
What Is A Holiday Pay Claim And When Do Employers Face One?
A holiday pay claim is typically brought where an employee or worker believes they were underpaid for statutory annual leave (5.6 weeks per leave year for full-time workers in the UK) or were not allowed to take paid leave at all. Claims usually appear as “unlawful deduction from wages” in the Employment Tribunal.
You’re most likely to face a claim if:
- Holiday pay was calculated at basic pay only when “normal remuneration” should have been used (for example, excluding guaranteed overtime, regular non-guaranteed overtime or sales commission).
- Irregular hours or part-year workers accrued leave incorrectly, especially following the 2024 reforms to the Working Time Regulations.
- There’s poor record-keeping around leave accrual and pay, making it hard to evidence what’s been paid and why.
- Employees weren’t encouraged or enabled to take paid leave and it built up across years.
If you receive a grievance or a letter before claim, treat it seriously and investigate promptly. A quick internal fix or settlement can often save significant time, cost and distraction compared to a Tribunal dispute.
Holiday Pay Law In The UK: The Essentials You Need To Know
The core rules sit under the Working Time Regulations 1998 (WTR) and the Employment Rights Act 1996 (ERA). Here are the key legal points employers should have on their radar:
- Statutory entitlement: Most workers are entitled to 5.6 weeks’ paid annual leave each leave year (pro-rated for part-time). Four weeks derive from EU law (“Reg 13 leave”) and 1.6 weeks from UK law (“Reg 13A leave”).
- Normal remuneration: Case law has established that the 4-week EU portion should be paid at “normal remuneration”. In plain English, that usually means including regular overtime and commission that a worker would normally have earned if they hadn’t taken leave.
- 2024 reforms for irregular hours and part-year workers: The Government has clarified accrual and authorised rolled-up holiday pay for these categories from 2024, subject to conditions. Many employers now use a 12.07% accrual method on hours worked for these workers, with rolled-up holiday pay expressed transparently on payslips. Get advice to ensure your model matches the current WTR rules and your workforce profiles.
- Carry-over and missed leave: Workers can carry over leave in certain situations (e.g. long-term sickness or family leave). Where an employer fails to enable paid leave, leave can in some cases carry forward, creating larger liabilities.
- Time limits: Unlawful deduction from wages claims are generally brought within 3 months less one day of the last alleged deduction. A “series of deductions” can be claimed - however, in England and Wales there’s usually a two-year backstop on how far back a series can go.
- Records: Employers must keep adequate records of working time and paid leave. Clear records are critical if a dispute arises.
Because working time compliance is a broad topic, it’s worth revisiting your obligations under the Working Time Regulations and your wider duties around working hours and breaks so your policies and practices align across the board.
Calculating Holiday Pay Correctly (Irregular Hours, Overtime And Commission)
Getting the calculation right is half the battle. The right approach will depend on your workforce, how they’re paid, and what they “normally” earn.
1) Basic Salary Workers
For salaried staff with no overtime or variable pay, holiday pay often equals normal salary. However, check whether they also receive regular allowances, supplements or performance-related payments. If these are part of normal remuneration, they may need to be reflected in the 4-week EU portion.
2) Overtime
Where overtime is regularly worked and forms part of normal pay, it should be reflected when calculating holiday pay for at least the 4-week EU portion. Keep consistent, auditable rules about what counts as “regular”. Many employers look over a reference period (for example, 52 weeks) to find an average.
3) Commission And Bonuses
Sales commission that workers would have earned if they hadn’t taken leave is usually included in the 4-week EU portion. The easiest way to handle this is through a transparent averaging method over a reference period. If performance pay is a big component in your business, align your bonus and commission arrangements with your holiday pay method to avoid mismatches.
4) Irregular Hours And Part-Year Workers
From 2024, employers have more flexibility to use accrual and rolled-up holiday pay in specific circumstances for irregular hours and part-year workers. Many employers use an accrual rate (commonly 12.07%) applied to hours worked. If you roll up holiday pay, you must make it transparent on payslips and ensure you still allow workers to take time off as leave, not just receive extra pay.
Because these reforms can be tricky in practice, it’s wise to reflect your approach clearly in your Staff Handbook and contracts, and train your payroll team to apply it consistently.
How To Handle A Holiday Pay Claim Step-By-Step
If a worker raises a holiday pay issue (informally or via a formal grievance), follow a clear, fair process. It protects your business and builds trust.
Step 1: Acknowledge And Gather The Facts
- Acknowledge receipt quickly and outline your investigation timeline.
- Secure relevant records: contracts, payslips, timesheets, leave logs, commission/overtime data, handbooks and policies.
- Clarify what the worker says is missing (e.g. overtime not included for specific dates, rolled-up pay not itemised, incorrect accrual).
Step 2: Audit Your Calculation
- Recalculate the worker’s holiday pay using the correct reference period and the right components of pay.
- Check whether the claim spans a “series of deductions” and how the two-year backstop may apply.
- Document your methodology in plain English so it’s easy to explain and repeat.
Step 3: Decide On Rectification Or Response
- If there’s an underpayment, pay the shortfall promptly and confirm in writing. Consider interest if appropriate.
- If you disagree, set out your calculation and reasoning clearly with supporting records.
- Where there’s uncertainty (for example, borderline “regular” overtime), a pragmatic settlement can save time and cost.
Step 4: Engage Early Conciliation If A Tribunal Claim Is Threatened
Most Tribunal claims must start with ACAS Early Conciliation. Use this window to reach a resolution. If the matter proceeds, ensure your records and witness statements are in order and get legal advice early to manage risk and costs.
Step 5: Fix The Root Cause
- Update your contracts and policy language to reflect your holiday pay model, especially for irregular hours staff.
- Train payroll and line managers to apply the rules consistently.
- Improve visibility - itemise holiday pay elements on payslips and make accruals transparent.
If you’re unsure whether your deductions or offsets are lawful, revisit your obligations on wage deductions and ensure any adjustments are expressly authorised.
Preventing Future Holiday Pay Claims: Contracts, Policies And Record-Keeping
Prevention is always easier than defence. A few targeted improvements will dramatically cut your risk profile.
Use Clear, Updated Contracts
Your contracts should explain how holiday pay is calculated for the specific role and hours pattern, and reference any averaging or accrual method you use. If you need to refresh your templates, consider a professionally drafted Employment Contract that addresses variable pay, overtime and holiday pay calculations in a way that aligns with law and your payroll system.
Strengthen Your Policies
- Make your holiday policy easy to follow: how to request leave, how leave accrues, and how pay is calculated.
- Encourage workers to take leave each year and keep evidence that you’ve reminded them - this helps avoid build-up and carry-over disputes.
- Bring your approach to breaks and working hours in line with your leave policy so everything fits together under the working time rules.
Keep Robust Records
Consistent, accurate records are your best defence. Maintain:
- Hours worked and overtime logs
- Commission/bonus records and how they’re calculated
- Leave requests, approvals, and leave taken
- Payslips showing holiday pay components (especially if you use rolled-up pay for eligible workers)
Audit And Correct Proactively
Run periodic audits on holiday pay calculations, particularly for sales teams and irregular hours workers. If you spot historic errors, a voluntary correction exercise (with clear explanations and back-pay) can reduce the likelihood of claims and minimise the scope of any “series of deductions”.
Manage Disputes Calmly And Fairly
Disagreements about pay can spill into broader workplace conflict and even a breach of employment contract allegation if not handled well. A clear, written process in your Staff Handbook for raising and resolving pay concerns will help you respond consistently and lawfully.
Finally, think holistically. If your business also makes deductions for equipment, training costs or advances, sense-check your processes against your obligations on lawful deductions so one issue doesn’t create another.
Key Takeaways
- Holiday pay claims usually arise when “normal remuneration” hasn’t been used for the 4-week EU portion, or when accrual for irregular/part-year workers hasn’t been calculated in line with the 2024 Working Time Regulations reforms.
- Act fast on any holiday pay complaint: acknowledge, gather records, recalculate using a clear reference period, and either rectify underpayments promptly or set out your position with evidence.
- Know the time limits: unlawful deduction claims are typically within 3 months less one day of the last deduction, with a two-year backstop for a series of deductions in England and Wales.
- Get the maths right for overtime, commission and irregular hours. Align your payroll method with clear wording in your Employment Contract and Staff Handbook.
- Prevention beats defence: keep excellent records, encourage leave to be taken, and run periodic audits. Make sure your processes fit the Working Time Regulations and your broader working time rules.
