Holiday disputes are often calculation disputes disguised as policy disputes. Start with worker status, leave year, working pattern, statutory and contractual entitlement, what leave was taken and how holiday pay was calculated.
Start with the factual problem, then identify the right, evidence, remedy and route. Similar workplace situations can use different legal tests.
Key points
- Almost all workers are entitled to 5.6 weeks of statutory paid annual leave.
- Irregular-hours and part-year workers can accrue statutory leave at 12.07% of hours worked under the current rules.
- Rolled-up holiday pay is permitted for irregular-hours and part-year workers under the current regime, subject to the statutory method and payslip transparency.
- Carry-over rules can apply where sickness, family leave or employer failures prevented leave being taken.
Diagnosis
First: what exactly happened?
Work out which route fits the facts before deciding what to ask the employer to do. Similar workplace problems can use different legal tests.
| What happened? | What to check |
|---|---|
| The employer says you have less holiday than expected | Check status, working pattern, leave year, contractual enhancement and the statutory calculation. |
| Holiday has been refused or cancelled | Check notice, operational reason and whether the employer is still giving a realistic opportunity to take statutory leave. |
| Holiday pay is lower than normal pay | Identify whether normal remuneration, overtime/commission or the 52-week reference period applies. |
| You are irregular-hours or part-year | Check the 12.07% accrual rules and whether rolled-up holiday pay is being used lawfully. |
| You were sick or on family leave | Check carry-over rights and whether annual leave continued to accrue. |
Who is responsible?
The employer remains responsible for complying with employment law and making fair decisions even where managers, HR, payroll, occupational health or external advisers administer part of the process.
Identify your employing entity and the actual decision-maker. If an agency, umbrella company or host business is involved, responsibility can differ by right and should be checked rather than assumed.
The 5.6-week statutory minimum
Most workers are entitled to 5.6 weeks paid annual leave. For a five-day worker this is usually 28 days, and bank holidays can be included in that total.
Irregular-hours and part-year workers
For leave years beginning on or after 1 April 2024, statutory entitlement for qualifying irregular-hours and part-year workers is generally accrued at 12.07% of hours worked in each pay period.
Holiday pay calculation
Holiday should not normally leave workers financially worse off in a way that discourages leave. The calculation depends on working pattern and pay components, including relevant regular overtime or commission in some cases.
Rolled-up holiday pay
Current rules allow rolled-up holiday pay for irregular-hours and part-year workers only, using the statutory method and showing the holiday-pay element separately.
Carry-over
Carry-over can apply where sickness or family leave prevented leave being taken, or where the employer failed to recognise the right, give reasonable opportunity to take leave or warn that leave would be lost.
Leaving employment
Untaken statutory holiday is normally paid on termination, while over-taken leave can only be deducted where there is a lawful basis.
Holiday when employment ends
On termination, the employer should calculate accrued but untaken statutory leave and include the appropriate payment. The contract may contain a lawful method for deducting over-taken leave, but do not assume a negative holiday balance automatically authorises a deduction.
Ask for the leave accrual calculation up to the termination date, the leave already taken and the pay rate used. This is especially important for irregular-hours workers, starters/leavers part-way through a leave year and anyone whose pay varies.
Sickness, family leave and annual leave can overlap
Annual leave continues to accrue during sickness and statutory family leave. A worker who becomes sick during booked holiday can have rights to treat the period as sickness instead, subject to notification and evidence requirements. Family leave and annual leave cannot simply be taken at the same time, so accrued leave may need to be taken before or after.
Carry-over rules protect entitlement where a worker could not take leave because of sickness or family leave. The precise amount and deadline can depend on the reason for carry-over and the worker category, so record the leave year and the event that prevented leave being taken.
Normal pay and holiday pay are not always identical calculations
For workers with regular hours and fixed pay, holiday pay is usually straightforward. Where pay varies through regular overtime, commission or allowances, the statutory calculation can be more complex. The point is to identify which elements form part of normal remuneration for the relevant portion of statutory leave rather than assuming basic salary is always enough.
Ask for the employer calculation and the reference period used. If a week with no pay has been included where the statutory method says it should be ignored, or regular earnings have been omitted, challenge the arithmetic rather than merely saying the result feels low.
Booking leave and employer refusals
Workers have a right to statutory leave, but not an unrestricted right to take any chosen dates. Employers can operate booking rules and can refuse particular dates if the legal notice requirements are met. The practical question is whether the worker is still being given a genuine opportunity to take the statutory entitlement during the leave year.
If repeated refusals make it practically impossible to take leave, keep each request and refusal. This can become important to carry-over and enforcement questions, especially where the employer also failed to encourage leave or warn that entitlement would otherwise be lost.
What can you realistically ask for?
Match the requested outcome to the right involved. Some problems can be corrected internally; others have statutory pay, compensation or tribunal remedies.
- Correct leave balance
- Permission/opportunity to take statutory leave
- Corrected holiday pay
- Carry-over where statutory conditions are met
- Payment for untaken accrued leave on termination
Evidence worth keeping
Preserve the original record where possible. A short, dated evidence set is usually more useful than an unstructured dump of documents.
Common employer responses - and what they do not necessarily prove
| Employer says | ConsumerWise view |
|---|---|
| “You are casual, so you do not get paid holiday.” | Most workers, including many casual and agency workers, have statutory holiday rights. |
| “Untaken leave always expires at year end.” | Not always. Statutory carry-over can apply in several circumstances. |
| “Rolled-up holiday pay is always unlawful.” | That is outdated for qualifying irregular-hours and part-year workers under the current rules. |
| “Bank holidays must be extra on top of 5.6 weeks.” | Not necessarily. An employer can count bank holidays within the statutory 5.6 weeks unless the contract gives more. |
What to say next
Write in issue-remedy form: identify the event, state the rule or evidence that matters, ask the employer to explain its position, and request a concrete outcome. Avoid burying the key point inside a long narrative.
Important overlaps and edge cases
- Sickness and family leave
- Employment status
- Pay/deductions
- Working time and rest
What to do
A practical next-step plan
- Write down the event or decision, the date, who made it and the practical impact.
- Identify the legal or contractual right that may apply instead of relying only on the word “unfair”.
- Collect the smallest evidence set that proves the key facts and the employer’s stated reason.
- Use the relevant internal request, grievance, appeal or complaint route and ask for a specific remedy.
- Check Acas and tribunal limitation separately. Do not let a slow internal process cause an external deadline to expire.
Escalation and time limits
Internal procedures can be important, but they do not normally stop an employment tribunal time limit. As at 11 September 2026, most claims whose limitation period starts before 1 October 2026 still use the existing three-month-minus-one-day framework. For most relevant time limits starting on or after 1 October 2026, the period increases to six months minus one day.
Acas early conciliation can affect calculation of the deadline if Acas is notified in time. Some claims use different limits, and interim relief in qualifying dismissal cases can require action within only 7 days. Always check the specific claim rather than applying a general period mechanically.
