Do I have to give notice in writing?

Not legally in most UK employment contracts, but strongly recommended. Written notice fixes the date and terms, protects both sides in any dispute, and creates a clean record on your HR file. Verbal resignation followed by written confirmation is also common.

Should I email or hand in a printed letter?

Email is standard for most UK employers in 2026 and gives a timestamp. Printed letters remain conventional in medicine, law, senior civil service and some parts of the armed forces. Follow the convention in your sector; when in doubt, email plus a printed copy.

What if my employer refuses to accept the letter?

Resignation is a unilateral act - your employer cannot refuse it. If they push back, follow up with a written confirmation of the date the letter was delivered. Your notice period runs from the delivery date, not the acceptance date. See can my employer reject my resignation for the detail.

Should I give a reason for leaving?

No obligation to. A brief general statement (personal reasons, new opportunity, retirement) is enough. Detailed reasons belong in the exit interview if you choose to share them, not in the letter. Keep the letter tight.

What tone should the letter use?

Professional and factual. Avoid emotional language, criticism or grievance content. Warm can be appropriate for retirement or after long service; neutral is the default for most resignations. Firm is appropriate only where the resignation itself is a formal response to a serious breach.

What every notice period letter must include

The date. The date you deliver the letter fixes the start of your notice period.
Clear statement of resignation. A single unambiguous sentence: "I am writing to formally tender my resignation from my role as [Role] at [Employer]."
Your final working day. Calculated from your contractual notice period. Use the final working day calculator to work it out.
Handover offer. A brief line offering to support the handover during notice.
Professional sign-off. "Yours sincerely, [Your Name]" plus your role for reference.

Optional: brief thanks for the opportunity, particularly if the departure is amicable. Avoid grievances, criticism or explanations of your next role. Everything you write goes on your HR file.

Standard resignation letter

The safe default for most resignations. Suits any role, sector or seniority where the departure is straightforward.

[Date]
Dear [Line Manager Name],
I am writing to formally tender my resignation from my role as [Role Title] at [Employer Name].
In accordance with my contractual notice period, my last day of employment will be [Final Working Day].
I would like to thank you for the opportunities I have had during my time here. I am committed to ensuring a smooth handover of my responsibilities and will do everything I can to support the team during my notice period. Please let me know how you would like me to prioritise this.
Yours sincerely,
[Your Name]
[Role Title]

Short-notice resignation (probation)

For resigning during probation, where the contractual notice is one week to one month.

[Date]
Dear [Line Manager Name],
I am writing to give notice of my resignation from my role as [Role Title] at [Employer Name].
In accordance with the probationary notice period in my contract, my last day of employment will be [Final Working Day].
Thank you for the opportunity to join the team. I will support the handover of my current work during my notice period.
Yours sincerely,
[Your Name]

Resignation with immediate effect

For rare cases where immediate resignation is lawful (constructive dismissal, employer breach). Take legal advice before using this route. Standard walk-out breaches the contract.

[Date]
Dear [Line Manager Name],
I am writing to tender my resignation from my role as [Role Title] at [Employer Name] with immediate effect.
[If constructive dismissal: I am resigning in response to fundamental breaches of my contract of employment, specifically [briefly reference nature of breach]. I reserve all rights arising from this constructive dismissal.]
I will return company property including [items] by [date].
Yours sincerely,
[Your Name]

For the framework see constructive dismissal UK and take advice before sending.

Warm retirement letter

For those retiring after long service. Warmer tone is appropriate.

[Date]
Dear [Line Manager Name],
After [Number] years at [Employer Name], I have decided that the time is right to retire. Please accept this letter as formal notice of my resignation from my role as [Role Title].
In accordance with my contractual notice period, my last day of employment will be [Final Working Day].
My time here has been extremely rewarding, and I am grateful for the opportunities, colleagues, and experiences I have had. During my notice period I will focus on completing a thorough handover of my responsibilities.
I would welcome a conversation about how to make my final months as productive as possible for the team.
Yours sincerely,
[Your Name]

Delivery: email vs printed letter

Email is acceptable for most modern UK employers and is preferred by many because it provides a timestamp. Best practice:

Send to your direct line manager with HR copied.
Use a clear subject line: "Resignation - [Your Name]".
Attach the letter as a signed PDF, or paste into the email body.
Request written confirmation of receipt.

Printed and hand-delivered letters are still used in some traditional professions (medicine, law, senior civil service) and give visual weight. Follow the convention of your sector.

What NOT to include

Grievances or complaints. Raise these separately through the grievance procedure.
Criticism of colleagues, managers or the company. Nothing to gain, plenty to lose.
Details of your next role. Not their business unless you choose to share informally.
Emotional language. Keep it professional and factual.
Contractual demands or threats. Separate these into a formal legal channel if needed.

Calculate your final working day first

Get the date right. Common errors: counting weeks instead of months, forgetting bank holidays, mis-counting a partial month. Use the notice period calculator and the final working day calculator to fix the date before drafting the letter.

For sector-specific notice: NHS notice period calculator, teacher notice period calculator, or the probation end date calculator for probationary staff.
