How to Write a Resignation Letter
A UK resignation letter is short and formal: state that you are resigning, give your intended last day based on your notice period, and thank your employer, without needing to explain your reasons in detail. Check your contract first, since your notice period will usually be written there.
Check your notice period first
Before you write anything, check your contract of employment for your notice period. This is usually stated clearly, often as a set number of weeks or a month, and can vary between jobs.
Your resignation letter should give your last working day based on that notice period, counted from the day you hand in your notice, unless your employer agrees to something different.
If you cannot find your contract or are unsure of your notice period, it is worth asking your manager or HR directly before writing your letter, so the date you give is correct.
If you are still within a probationary period, check your contract carefully, since the notice period during probation is sometimes shorter than the standard notice period that applies afterwards.
What a resignation letter needs to include
At minimum, a resignation letter should state that you are resigning, name your job title, and give the date you intend to leave based on your notice period.
It is normal, though not required, to add a short, polite line thanking your employer for the opportunity, and offering to help with a smooth handover if appropriate.
You do not need to explain in detail why you are leaving. A brief, neutral reason is fine if you want to include one, but it is not expected.
If you are leaving for a positive reason, such as a new role, it is fine to mention this briefly, but there is no need to go into detail about the new employer or the role itself.
Keep it short and professional
A resignation letter is usually just a few short paragraphs. It does not need to be long, emotional, or go into detail about your reasons for leaving.
Keep the tone calm and professional, even if you are leaving because you are unhappy in the role. A resignation letter can affect a future reference, so it is worth keeping it measured.
Avoid using the letter to raise complaints or unresolved issues; if there is something you want to discuss, a separate, direct conversation is usually a better place for it.
A simple structure to follow
State your resignation and job title, give your last working day based on your notice period, add a short thank-you, and close with a formal sign-off.
This structure keeps the letter short and clear, and covers everything an employer needs from a resignation letter without unnecessary detail.
Once you have the structure in mind, the letter itself usually takes only a few minutes to write.
Example resignation letter
'Dear Mr Ahmed, I am writing to formally resign from my position as Sales Assistant at Oakfield Retail. In line with my notice period, my last working day will be 17 October 2026. Thank you for the opportunity to work with the team over the past two years. I am happy to help with handing over my responsibilities during my notice period. Yours sincerely, Jordan Lee'
This example is short, clear, and states the last working day plainly, based on a notice period already checked against a contract.
Delivering your resignation
It is common to tell your manager in person first, then follow up with a written letter or email confirming it formally. Check your contract, since some employers set out exactly how resignation should be given.
Keep a copy of your resignation letter or email for your own records, along with any written reply confirming your last working day.
If your workplace has a specific HR process for resignations, follow it alongside giving your manager the letter directly.
If you are unsure how your manager will react, choosing a reasonably quiet, private moment to raise it, rather than during a busy shift, tends to make the conversation easier and less stressful for both of you.
Handling the notice period
Once you have resigned, continue to work your notice period as normal unless your employer agrees to release you earlier or offers pay in lieu of notice.
Use the remaining time to hand over your work as clearly as you can, which helps keep things professional and can matter for any future reference.
If your circumstances change during your notice period, such as needing to leave earlier, raise it directly and politely with your manager rather than simply not turning up.
If your employer asks you to stay
Occasionally an employer responds to a resignation by asking what it would take for you to stay, sometimes called a counteroffer. Take time to think this through properly rather than deciding on the spot.
Consider why you decided to resign in the first place, and whether whatever is being offered actually addresses that reason, or simply delays the same decision to a later date.
Whatever you decide, keep the conversation calm and professional. There is no obligation to accept a counteroffer, and equally no obligation to explain your reasoning in detail if you would rather not.
If you do decide to withdraw your resignation and stay, ask for anything agreed, such as a change in hours or pay, to be confirmed in writing, in the same way any other change to your employment terms would be.
