Yes, your employer can usually refuse the particular dates you request, or cancel approved leave, but cannot refuse to let you take your statutory holiday altogether. The refusal or cancellation must follow the required notice rules, and Acas says there should be a good business reason. Your contract or handbook may set different notice procedures, so check those as well as the statutory rules.
Most UK workers are entitled to 5.6 weeks of paid statutory annual leave each leave year. Bank holidays can be included in that total. The important distinction is between refusing dates and preventing you from using the entitlement at all.
What an employer can and cannot do
Annual-leave law gives an employer control over when leave is taken, subject to limits. A business can manage staffing, impose busy-period restrictions, operate a shutdown, or ask workers to take leave at specified times. It can also reject a proposed date or withdraw approval later.
That control is not unlimited. GOV.UK guidance states that an employer can refuse a leave request or cancel leave, but must give notice at least equal to the amount of leave requested plus one day, unless the contract says otherwise. The same guidance makes clear that an employer may refuse leave at a particular time but cannot refuse to let workers take their entitlement altogether.
#1 Best Overall
Acas says an employer should have a good business reason to refuse or cancel a holiday request. A refusal is therefore not automatically unlawful just because the reason is inconvenient to you. The legal problem arises when refusals, restrictions or cancellations leave you without a reasonable opportunity to use your statutory allowance.
How much statutory leave you should receive
Most UK workers receive 5.6 weeks of paid statutory holiday in each leave year under current GOV.UK guidance. Bank holidays may be counted within those 5.6 weeks rather than added on top. The number of days represented by 5.6 weeks depends on your working pattern.
| Working pattern | How the statutory figure works | What to check |
|---|---|---|
| Regular five-day week | 5.6 weeks multiplied by five working days, commonly 28 days | Whether bank holidays are included in the employer’s stated total |
| Part-time regular hours | 5.6 weeks of your normal working week, producing a pro-rata number of days or hours | How the employer records leave in hours or days |
| Irregular-hours or part-year work | The statutory calculation and carry-over rules can differ from those for regular full-year workers | Your contract, leave records and the applicable current guidance |
A contractual holiday allowance can be more generous than the statutory minimum. Your employer may also impose contractual rules about when requests must be submitted, blackout periods, minimum blocks of leave or a fixed company closure. Those rules cannot be used to remove the statutory opportunity to rest and take paid leave.
Notice rules for requesting, refusing and cancelling leave
The ordinary statutory notice framework is in regulation 15 of the Working Time Regulations 1998. GOV.UK expresses the usual worker notice as twice the length of the leave requested, plus one day. An employer refusing or cancelling must normally give notice equal to the amount of leave concerned, plus one day. A contract can set a different rule, so compare the statutory default with your written terms.
| Event | Ordinary statutory notice described by GOV.UK | Example |
|---|---|---|
| You request leave | At least twice the length of the leave requested, plus one day | A five-day request normally requires at least 11 days’ notice |
| Employer refuses the request | At least the length of the requested leave, plus one day | A five-day request normally requires at least six days’ notice of refusal |
| Employer cancels approved leave | At least the length of the leave being cancelled, plus one day | A five-day booking normally requires at least six days’ notice of cancellation |
| Contractual variation | The contract or handbook may require more, less or differently calculated notice | Follow the written term if it is lawful and clear |
These are notice periods, not a guarantee that the request will be approved. Submit requests through the required system or form and keep the date and time of submission. If your employer responds late, record when the decision actually reached you.
When refusing particular dates can be lawful
Staffing and operational pressure
A genuine staffing problem can justify refusing a requested week, especially where several colleagues seek the same dates or the work involves a fixed minimum staffing level. The employer should still identify alternative dates that give you a realistic chance to use your allowance during the leave year.
Rank #3
Busy periods and blackout dates
Employers can restrict leave during predictable busy periods, such as seasonal demand, a scheduled launch or an examination period, if the policy is communicated and applied consistently. A blackout covering every practical opportunity to take statutory leave would not satisfy the requirement to let workers take the entitlement.
Company shutdowns and directed leave
An employer can close the workplace for a period or direct workers to take leave at specified times. It must give advance notice and must still provide the statutory rest entitlement. Check whether shutdown days are deducted from your holiday balance and how bank holidays are treated.
Conflicting requests and policy criteria
A fair rotation, first-come process or limit on the number of people absent can be a legitimate way to choose between competing requests. Ask which policy was applied if you believe similar requests were treated differently.
When a refusal or cancellation becomes a problem
An employer cannot use repeated refusals to make statutory leave impossible in practice. Warning signs include:
- Every request is rejected without a workable alternative.
- The only dates offered are after the leave year ends.
- You are not told that unused leave may be lost.
- A cancellation leaves no realistic time to rebook before the leave year closes.
- The employer’s stated policy conflicts with the written contract or is applied inconsistently.
Acas’s position is that employers must ensure workers can take the holiday to which they are entitled and should have a good business reason for refusing or cancelling. The question is not whether you obtained your first-choice dates, but whether the employer provided a genuine opportunity to take the statutory amount.
What to do when your request is refused
- Check the documents. Read your contract, staff handbook and holiday policy. Confirm the leave year, notice period, blackout dates, shutdown arrangements and whether bank holidays are deducted.
- Check your balance. Record statutory and contractual entitlement separately if your payroll system does so. Note leave already booked, taken or carried over.
- Ask for the reason in writing. Keep the refusal email or screenshot. If the employer only gives a verbal answer, send a neutral message confirming what you understood and ask whether it is correct.
- Request alternatives. Offer specific dates rather than asking generally when you may take leave. Explain if the refusal will leave statutory days unused before the leave year ends.
- Check the notice calculation. Compare the date you submitted the request and the date of the refusal with the amount of leave involved. If the contract has a different rule, identify that clause.
- Escalate internally. Use the company’s grievance, HR or manager-review process if repeated refusals continue. Attach your request history, refusals, policy and remaining balance.
- Seek practical guidance. Acas is the appropriate practical escalation point for an unresolved holiday-entitlement or holiday-pay dispute. Keep copies of everything you provide.
If approved annual leave is cancelled
Cancellation is treated differently from a refusal before approval because you may have arranged travel, childcare or other commitments. The employer still has to give the required notice—normally the length of the leave plus one day, unless the contract says otherwise—and should have a good business reason.
Ask the employer to confirm the cancellation date, reason, replacement dates and how the leave balance will be restored. Check your contract or policy for rules about costs caused by a cancellation. The available compensation, if any, is fact-specific; there is no universal payment figure established by the guidance covered here.
If the cancellation leaves you unable to use your statutory allowance, state that in writing immediately and propose replacement dates within the current leave year.

Unused holiday does not automatically carry over in every situation. However, carry-over protections may 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. GOV.UK and Acas explain that the amount and operation of any carry-over depend on the worker’s circumstances.
Recommended Free Tools
| Situation | What to establish | Why it matters |
|---|---|---|
| Regular-hours worker | Which dates were offered, refused or cancelled and whether a realistic opportunity remained | Repeated refusal can support an argument that the employer did not enable use of the entitlement |
| Irregular-hours or part-year worker | How entitlement was calculated and which leave-year rules apply | Carry-over and calculation arrangements can differ |
| Sickness absence | Dates of absence, leave-year deadline and communications about taking holiday | Special carry-over protections may apply |
| Family-related leave | The type and dates of leave and any holiday discussions | Different carry-over protections may apply |
Do not assume that an employer’s refusal proves every unused day must be carried forward. Preserve the evidence showing what you requested, what was offered, whether you were encouraged to use leave and whether you were warned of a loss deadline. Ask the employer to confirm its position before the leave year ends.
Refusal before booking versus cancellation after approval
| Issue | Request refused | Approved leave cancelled |
|---|---|---|
| What changes | The proposed dates never become approved leave | Existing approval is withdrawn |
| Notice | Normally the requested leave length plus one day | Normally the cancelled leave length plus one day |
| What to ask for | The business reason and realistic alternative dates | The reason, replacement dates and restoration of your leave balance |
| Main risk | Repeated refusals consume the remaining leave year | Short-notice disruption and inability to rebook |
Employer records and your evidence from April 2026
From 6 April 2026, employers must keep annual-leave and holiday-pay records for at least six years, according to Acas. This does not remove your need to keep personal evidence. Save request confirmations, refusal messages, rota information, policy versions, approval notices, cancellation messages and screenshots of your leave balance.
Keep a simple timeline showing each request, the dates requested, the notice given, the decision, the reason, alternatives offered and the resulting balance. A clear chronology helps distinguish a one-off operational refusal from a pattern that prevented you from taking statutory leave.
Quick Recap
Questions to ask your employer
- What business reason supports refusing these dates?
- Which policy or contract term applies?
- What alternative dates can I use before the leave year ends?
- How many statutory and contractual days remain?
- Are bank holidays included in the figure shown?
- If the days cannot be used, will the employer recognise carry-over and on what basis?
- If approved leave is cancelled, when will the leave balance be restored?
Key takeaways
- A refusal of particular dates can be lawful; a blanket refusal of all statutory holiday is not.
- Under the ordinary GOV.UK notice rule, the worker gives twice the requested leave plus one day, while the employer refusing or cancelling gives the requested amount plus one day, subject to the contract.
- Busy periods, shutdowns and directed leave are possible, but the employer must give advance notice and preserve a genuine opportunity to take statutory leave.
- Repeated refusals, no alternatives and no warning about lost leave may support carry-over protections.
- Document every request and response, and use Acas if the dispute remains unresolved.
