They cannot simply prevent you from taking your entire entitlement.
The practical answer depends on your contract, leave year, working pattern, the notice given and why the dates were refused. This guide explains the notice calculations, lawful restrictions, repeated refusals, cancelled bookings and what to do if the leave year is ending.

What the law actually allows
Most UK workers are entitled to 5.6 weeks of paid statutory holiday each leave year. Bank holidays can be included within that 5.6-week total rather than added on top. The number of days this represents depends on how you work and on the leave rules in your contract.
The law separates two issues:
- Timing: whether you may take leave on particular dates.
- Access: whether you are given a reasonable chance to take the statutory amount during the leave year.
An employer can control timing for genuine operational reasons. It cannot use refusals, blackout periods or cancellations to make the statutory entitlement impossible to use. Acas says an employer should have a good business reason to refuse or cancel a holiday request.
#1 Best Overall
How much notice must each side give?
The ordinary notice framework comes from regulation 15 of the Working Time Regulations 1998. Your contract, collective agreement or holiday policy may set a different rule, so check those documents before relying on the default calculation.
| Action | Ordinary statutory notice | Example for five days of leave |
|---|---|---|
| You request leave | At least twice the length of the leave requested, plus one day | At least 11 days’ notice |
| Employer refuses the request | At least as much notice as the amount of leave requested, plus one day | At least six days’ notice |
| Employer cancels approved leave | At least as much notice as the amount of leave being cancelled, plus one day | At least six days’ notice |
These are the ordinary statutory calculations expressed by GOV.UK. They are measured against the length of the leave block, so a longer booking requires a longer notice period. A workplace rule can require requests earlier than the statutory minimum or can provide a different cancellation process.
What counts as a refusal?
A refusal is a decision that you cannot take the requested dates. It is not automatically unlawful just because the dates were inconvenient for you. The employer should be able to explain the business reason and should not leave you without a realistic alternative during the leave year.

What counts as a cancellation?
Cancellation is different because the dates had already been approved. The same ordinary employer notice calculation applies unless your contract says otherwise. Check whether the approval was recorded in a rota, booking system, email or written form; that evidence matters if the cancellation is disputed.
When can an employer refuse particular dates?
A business can manage when leave is taken. Common examples include:
- busy trading or production periods when minimum staffing is needed;
- a planned workplace shutdown or compulsory closure;
- overlapping requests that would leave a team below safe or workable staffing levels;
- limits in a written holiday policy, such as a peak-season restriction or a maximum number of people away at once.
The restriction should be applied consistently and communicated through the contract, handbook, rota process or a clear instruction. A bare “no” with no explanation may be difficult to justify, especially where the refusal is repeated and no alternative dates are offered.
Busy periods and blackout dates
A blackout period can be lawful if it is a genuine operational rule and workers can still use their statutory allowance at other times. Ask which dates are unavailable, when the restriction applies and what dates remain open. If a policy was introduced after you booked leave, ask how existing approvals are treated and what notice is being given.

An employer may close the business for a period and require workers to use holiday then. It may also direct workers to take leave at another time. The employer must give advance notice and must still allow enough time for the statutory entitlement to be taken. The exact notice for directed leave can be set by the contract or policy, so read that wording rather than assuming the request formula applies.
Can your employer refuse all your holidays?
No. GOV.UK states that an employer can refuse leave at a particular time but cannot refuse to let workers take the leave at all. Acas gives the same practical rule: an employer cannot refuse to let workers take any holiday.
An employer could lawfully reject several individual requests if each proposed period conflicts with real business needs, but it must then provide a workable opportunity elsewhere in the leave year. A pattern that leaves you unable to use the statutory minimum is not cured by saying that you should have applied earlier if the business never made dates available.
Rank #3
Signs that refusals may be preventing entitlement
- Every request is rejected without alternative dates.
- Blackout periods cover most or all of the leave year.
- You are told to save the days but are never given a period when they can be used.
- Management knows the leave year is ending but gives no warning about unused days or no route to book them.
- Approvals are withdrawn so often that taking the entitlement becomes unrealistic.
One refusal does not prove a breach. The overall pattern, the reasons given and the time left in the leave year are what matter.
What if approved leave is cancelled?
First check the cancellation date against the length of leave being withdrawn. For a five-day booking, the ordinary minimum is six days’ notice unless your contract provides another rule. Keep the approval and cancellation messages together.
Ask the employer in writing:
- why the leave was cancelled;
- whether the cancellation applies to all staff or only your booking;
- which alternative dates are available; and
- how the change will be recorded in your leave balance.
If you have already paid for travel or accommodation, the employment-law notice rule does not automatically set a reimbursement amount. Check any contractual promise, workplace policy or insurance separately, and avoid assuming that a cancelled booking guarantees compensation.
What happens when leave is refused repeatedly?
Act before the leave year closes. A clear written record can show that you tried to use the entitlement and that the employer controlled access to dates.
Build an evidence file
- your original requests, including the dates and length requested;
- the responses, reasons and notice given;
- the holiday policy, handbook or contract clause relied on;
- your current leave balance and the end date of the leave year;
- approved leave, later cancellations and any alternative dates offered; and
- messages showing whether managers warned that unused days could be lost.
Keep copies outside a system you may lose access to, while respecting workplace confidentiality and data-protection rules.

Ask for alternatives in writing
State the dates that were refused, the number of statutory days still unused and the date on which the leave year ends. Ask for specific alternative dates rather than an open-ended promise that “something may be available later”. Explain that the current refusals may leave statutory leave unused and request a written response.
Use the internal process
If the manager does not resolve the issue, use the employer’s grievance or HR process. Attach the chronology and focus on the practical remedy: dates that allow the entitlement to be taken, correction of the leave record and confirmation of the applicable policy.
Contact Acas
Acas is the practical escalation point for an unresolved holiday-entitlement or holiday-pay dispute. It can explain how the rules apply to your circumstances and what options exist before a formal claim. The available remedy depends on the facts; there is no single compensation figure for every refused request.
Can unused holiday carry over?
Unused days do not automatically carry over every time a request is refused. Carry-over protections can apply where the employer did not provide a reasonable opportunity to take leave, did not encourage its use, or failed to warn that it could be lost.
Recommended Free Tools
The amount and route of carry-over depend on the worker’s circumstances. The rules can differ for:
- workers with regular hours;
- irregular-hours and part-year workers;
- absence caused by sickness; and
- family-related leave.
That means the correct question is not simply “Were my dates refused?” It is whether, in the circumstances, the employer made the statutory leave reasonably available and gave the information needed to use it. Keep evidence of refused dates, available dates, warnings and your leave balance so that the issue can be assessed against the relevant category.
When the leave year is close to ending
Send a dated message identifying the remaining entitlement and asking for dates before the deadline. If none are offered, say so explicitly and ask the employer to confirm how the unused statutory days will be treated. Do not wait for an informal conversation to become your only evidence.

| Situation | What the employer may do | What you should check |
|---|---|---|
| Request refused before approval | Reject the proposed dates for a good business reason and offer a realistic opportunity at another time | Reason, notice, policy and remaining dates in the leave year |
| Approved leave cancelled | Cancel with the required notice unless the contract says otherwise | Approval record, cancellation date and replacement dates |
| Peak-period restriction | Block specified periods if the rule is genuine and statutory leave remains usable | Whether the restriction is written, consistent and limited |
| Shutdown or directed leave | Require leave during closure or another period with advance notice | Contract wording and whether the direction still permits the full entitlement |
| Repeated refusals near year-end | Refuse individual dates only if access is still realistically available | Carry-over protections and evidence that alternatives were unavailable |
How working patterns affect the answer
The 5.6-week entitlement is a weeks-based minimum, not a promise of the same number of Monday-to-Friday days for everyone. Your working pattern affects the practical day count and the way leave is recorded. Irregular-hours and part-year workers have specific rules, and sickness or family-related absence can affect carry-over. If your hours vary, compare the employer’s calculation with the rules for your category rather than copying a full-time worker’s calculation.
Contractual holiday can be more generous than the statutory minimum. A refusal may therefore concern two different balances: the statutory portion protected by working-time law and any additional contractual days governed by your agreement. Check which balance the employer says is being refused or carried forward.
Holiday records from 6 April 2026
From 6 April 2026, employers must keep annual-leave and holiday-pay records for at least six years, according to Acas. The rule does not remove your responsibility to keep requests and approvals, but it gives disputes a clearer documentary trail. Ask for corrections if the recorded balance does not match approved, taken or cancelled leave.
A practical checklist
- Read the contract, handbook and leave-year dates.
- Calculate the ordinary notice: twice the requested leave plus one day for your request; the requested amount plus one day for an employer refusal or cancellation.
- Save the request, response, reason and leave-balance entry.
- Ask for realistic alternative dates if the request is refused.
- Escalate in writing before the leave year ends if refusals leave statutory days unused.
- Ask how carry-over will be handled where the employer did not provide a reasonable opportunity, encourage use or warn about loss.
- Contact Acas if the internal process does not resolve the entitlement or holiday-pay issue.
Bottom line for UK workers
Your employer can say no to particular annual-leave dates and can cancel approved leave, but it must follow the applicable notice rule and have a genuine business reason. It cannot refuse holiday altogether. If repeated refusals make the statutory allowance impossible to take, document the pattern, request alternatives before the leave year closes and raise carry-over with your employer and Acas.
