A leave application email is one of the most common workplace messages you will write — and one of the easiest to get wrong. Too short and it looks careless. Too long and your manager skims past the important bits. The templates below give you the right structure for every leave type, whether you are in a London office, a US remote team, or an Australian branch.

Key Takeaways

  • A leave application email needs four things: dates, leave type, handover plan, and any supporting documents (like a fit note).
  • Send it as early as possible — two weeks’ notice for planned leave, immediately for urgent absence.
  • UK employees requesting flexible working have a statutory right to make a request from day one of employment.
  • Australian employees should reference the correct leave type under the Fair Work Act 2009 — personal/carer’s leave, annual leave, or long service leave.
  • Do not use “TO WHOM IT MAY CONCERN” — address your manager or HR contact by name.

Template 1: Standard Annual Leave Email

This is the most common leave application. Adjust the dates and handover details.

Subject: Annual Leave Request — [Your Name] ([Dates])

Hi [Manager],

I would like to request annual leave from [Start Date] to [End Date], returning on [Return Date]. That is [X] working days.

I've updated the [Project] timeline to reflect my absence and [Colleague] has agreed to cover [specific responsibilities]. I'll make sure all deliverables due during this period are completed before I leave.

Please let me know if this works or if you need me to adjust the dates.

Thanks,
[Your Name]

It gives the manager everything they need to approve — dates, coverage, and a prompt to flag any conflicts.

Template 2: Short Notice Leave Application

When you need leave with less than the usual notice period, acknowledge the short notice and offer a handover plan.

Subject: Leave Request — [Your Name], [Dates] (Short Notice)

Hi [Manager],

I'm sorry for the late notice, but I need to take leave from [Start Date] to [End Date] due to [brief reason — e.g., a family matter]. I understand this is short notice and I'm happy to help with the transition before I go.

I've already [done X / spoken to Y about coverage]. If there's anything else I can do before [Date], let me know.

Thanks,
[Your Name]

Template 3: Unpaid Leave Email

Unpaid leave requires a stronger business case than paid leave, since the employer bears additional cost or disruption.

Subject: Unpaid Leave Request — [Your Name] ([Dates])

Hi [Manager],

I would like to request unpaid leave from [Start Date] to [End Date]. I have used my annual leave allocation for this year and need additional time for [reason].

I've reviewed my current workload and can complete [Task] before I go. [Colleague] has offered to cover [responsibility] during my absence.

I understand this is at your discretion. Happy to discuss further if needed.

Thanks,
[Your Name]

Template 4: Personal Leave Application

“Personal leave” covers reasons you may not want to specify. Keep it vague but professional.

Subject: Personal Leave Request — [Your Name] ([Dates])

Hi [Manager],

I need to take personal leave on [Date(s)] for a private matter. I expect to be back on [Return Date].

I've handed over [Task] to [Colleague] and will be available by phone if anything urgent comes up.

Thanks,
[Your Name]

Template 5: Leave Application for Medical Appointment

Most employers allow time off for medical appointments, but the process varies by country.

Subject: Appointment Leave — [Date]

Hi [Manager],

I have a medical appointment on [Date] at [Time] and will need to leave at [Time] / arrive late at [Time]. I expect to be back by [Time].

I've covered my morning meetings and will catch up on anything I miss.

Thanks,
[Your Name]

Template 6: Leave Application for a Full Week

When requesting a full week or more, provide more detail on handover and availability.

Subject: Annual Leave Request — Week of [Start Date]

Hi [Manager],

I'd like to request leave for the week of [Start Date] to [End Date] ([X] working days).

Here's the handover:
- [Project A]: [Colleague] has the latest version and can present to the client on [Date]
- [Project B]: I've completed the draft and it's in [shared location] for review
- Urgent queries: [Colleague] is the point of contact; I'll have limited email access

I'll make sure nothing is left pending before I go. Please let me know if this timing works.

Thanks,
[Your Name]

Template 7: Maternity Leave Application

These are more formal and often require specific notice periods. Check your employer’s policy before sending.

Subject: Maternity Leave Request — [Your Name]

Hi [Manager / HR],

I am writing to formally request maternity leave starting [Start Date]. Based on my expected due date of [Due Date], I plan to begin leave [X] weeks before, in line with [company policy / statutory entitlement].

I've prepared a handover document covering my current projects and key contacts. I'd like to schedule a handover meeting before my leave starts.

Please let me know if there are any additional forms or steps required.

Thanks,
[Your Name]

Template 8: Compassionate Leave Request

Compassionate leave (or bereavement leave) requires sensitivity. You do not need to provide excessive detail, but a brief mention helps your manager understand the urgency.

Subject: Compassionate Leave Request — [Your Name]

Hi [Manager],

I need to take compassionate leave effective immediately due to a bereavement in my family. I expect to need [X] days, but it's difficult to say exactly at this point.

[Colleague] can cover [responsibility] in the short term. I'll update you on [Date] about my expected return.

Thanks,
[Your Name]

Template 8: Study Leave Application

Some employers offer study leave for professional development. Reference your employer’s policy if one exists.

Subject: Study Leave Request — [Your Name]

Hi [Manager],

I'd like to request study leave on [Date(s)] for [exam / course / certification]. This relates to my professional development in [area], and I believe it will benefit the team by [brief benefit].

I've adjusted my workload to ensure nothing is missed during my absence. I'm happy to discuss this further if needed.

Thanks,
[Your Name]

Frequently Asked Questions

Can my employer refuse my leave request?

Yes. In most countries, employers can refuse leave if there is a genuine business reason — for example, a busy period, insufficient staffing, or a clash with other team members’ approved leave. The refusal should be communicated in writing with a reason.

Do I need to give a reason for annual leave?

No. Annual leave is your entitlement to take time off for any purpose. You are not required to explain why you want leave. However, some employers ask for a brief reason as a courtesy — providing one is optional but can help with approval.

What if my leave request overlaps with a colleague’s?

Employers typically manage this on a first-come, first-served basis or by operational priority. If both requests are for the same dates, your manager may ask one of you to adjust. This is a normal part of leave management and not a personal rejection.

Can I cancel my leave after it is approved?

Yes, but notify your manager as early as possible. If the leave has already been processed in payroll, your employer may need to adjust records. There is no legal barrier to cancelling approved leave.

Is a leave application email the same as a leave request?

They serve the same purpose. A leave application email is the written communication requesting time off. Many employers use digital leave management systems instead of email — but the same information (dates, type, handover) is required regardless of the format.
