To check holiday pay, first establish the leave year, working pattern and pay elements used in the calculation. Fixed-hours staff, irregular-hours workers and part-year workers may require different calculations under the applicable rules. [1]
Match leave taken with pay received
List approved leave dates and the payslips covering them. Record basic pay and variable elements such as regular overtime or commission separately. A flat daily amount may conceal that a relevant pay component was omitted.
Where hours vary, keep the work and pay history for the reference period used. Identify weeks without pay and changes in working pattern rather than averaging whichever payslips happen to be available.
Check the method, not just the total
Ask payroll which holiday pay method it used and why it applies to your worker category and leave year. If rolled-up holiday pay appears, establish whether that method is permitted for your circumstances and whether it is separately identified.
For leaving employment, reconcile accrued entitlement with leave taken and any final payment. Unpaid final wages covers the termination reconciliation; employment status matters if the employer says you have no holiday entitlement. Keep entitlement and payment calculations separate so an error in one does not conceal the other.
Establish the leave and pay questions separately Write down the employer's leave year and the dates of the holiday being checked. Record your working pattern during the relevant period, including changes between full-time, part-time or variable hours. The amount of leave accrued and the rate at which leave is paid are separate calculations. A correct balance in the booking system does not establish that payroll used the right pay rate. Likewise, a familiar daily rate does not show whether enough leave was allocated after a change in hours or another event affecting entitlement.
Ask which worker category and calculation method payroll has used. Irregular-hours and part-year arrangements have specific rules, and the everyday description casual may not settle whether those definitions apply. Supply the contract and actual hours pattern. Acas distinguishes holiday pay methods for different working arrangements. [1] Do not apply a percentage found online to every worker or assume that a method used for a colleague with different hours is necessarily suitable for you. The category and relevant leave year should be established before testing the arithmetic.
Reconstruct the relevant earnings history Collect payslips and work records covering the reference period used in the calculation. Separate basic pay, overtime, commission and other variable components, and identify weeks without pay. Ask how payroll treated holiday, sickness or other absence within the history. Selecting only the most recent available payslips may produce the wrong average. If you have worked for a shorter period, tell the adviser when the employment began so the appropriate method can be considered from the actual record rather than assuming a full history exists.
Check changes in pay and hours with their effective dates. A move to shorter hours should not simply erase leave accrued before the change. Keep the written variation and the booking record from each period. If the employer's system converted days into hours, request the conversion and explain any discrepancy. Different daily lengths can make a single days figure hard to interpret. A clear schedule showing accrual and use in the relevant units helps identify whether the disagreement concerns entitlement, conversion or the money paid for a particular holiday.
Examine how payment appears on the payslip Match each holiday period with the payroll period in which it was paid. If pay continues as usual, identify whether variable elements were included where required. If a separate holiday payment appears, ask how it was calculated. Where rolled-up holiday pay is used, establish whether that method is permitted for the arrangement and whether the amount is separately identified. A general statement that holiday is included in your rate is not enough to understand the calculation or confirm that the applicable requirements have been met.
Keep evidence of approved leave, cancellation and any instruction to take time off. Payment and the ability to take statutory leave should not be conflated. If the employer says a balance expired, ask which rule and circumstances it relies on, particularly where sickness, family leave or inability to take leave is relevant. Do not assume all unused leave automatically carries forward or always disappears. An adviser needs the reason it remained unused, the employer's communications and the relevant dates to assess the treatment.
Present a calculation that can be corrected Set out the holiday dates, method used by payroll, method or input you question and the resulting difference. Attach the payslips and work history supporting the point. If you do not yet know the correct figure, request the missing calculation rather than inventing a total. Ask payroll to explain any exclusion of a regular payment element. Keep its answer and compare it with the source data. A clear question about one calculation is more likely to reveal an error than a broad allegation that all holiday pay has always been wrong.
For employment ending, reconcile accrued leave, leave already taken and the final payment separately from ordinary wages. Check any deduction for leave taken beyond entitlement against the agreement and applicable rules. Record correction promises and payments without assuming an internal query protects a legal deadline. If several holiday periods are disputed, list each payday and amount for advice. The final evidence pack should show the working category, reference data, leave dates and calculation, allowing a specialist to assess both the method and any outstanding claim without relying on an unexplained net figure.
Frequently asked questions
Does a correct holiday balance prove that holiday pay is correct?
No. Entitlement and payment rate are separate calculations. Check the working pattern, relevant earnings and method used for the leave actually taken.
Can every casual worker be paid holiday using the same percentage?
No blanket assumption is safe. The legal working category, leave year and permitted calculation method must be identified from the actual arrangement.
What records help where regular overtime was excluded from holiday pay?
Keep the overtime and payslip history, leave dates and payroll explanation, so the relevant payment elements and calculation method can be assessed.
Should changing to part-time work remove leave already accrued?
Earlier accrual needs separate treatment from the changed period. Retain the effective date and request a calculation showing both working patterns.
Why list each disputed holiday payment separately?
The dates and amounts help identify repeated errors and assess time limits. An undated combined total can obscure which payments remain in dispute.
