How to Write a Resignation Letter: UK Templates and Tips

Most people write maybe three or four resignation letters in their whole career. So when the time comes, you stare at a blank screen thinking "how hard can this be?" and then spend 45 minutes overthinking it. It really does not need to be complicated. Get a few things right and you are done.

What matters is that it's clear, it's professional, and it nails down when your notice period starts. That last part matters more than most people realise.

How much Notice you have to give

Before you write anything, fix the date. If you have been employed for more than one month, the statutory minimum notice you must give your employer is one week. That is set by section 86(2) of the Employment Rights Act 1996 and repeated on GOV.UK. One week is the floor for everyone, however long you have been there. Unlike the employer's obligation, an employee's statutory notice does not grow with length of service.

Your contract almost certainly asks for more, and whichever is longer, contract or statute, is the one that binds you. If the contract is silent, the one-week statutory minimum applies.

Notice runs the other way as well. If your employer dismisses you, the statutory minimum they owe you is one week between one month and two years' service, then one week for each complete year, up to a ceiling of 12 weeks once you pass 12 years.

Why you need a written resignation

There is no legal requirement to resign in writing in the UK. But do it anyway. Here's why:

• It creates a paper trail. A written resignation pins down exactly when you gave notice. That determines your end date, your final pay and your holiday payout.
• Verbal resignations cause problems. Employment tribunals regularly deal with disputes over whether words spoken in temper amounted to a resignation at all. A dated written record removes the argument.
• It shows professionalism. You want your last impression to be a good one. A clean, written resignation does that.
• It protects you. If there's ever a dispute about your departure date, pay, or holiday, having a written resignation with a clear date on it is worth its weight in gold.

What to include in your resignation letter

Keep it short. Seriously. Nobody wants a two-page essay. You need five things:

1. A clear statement that you're resigning. Don't be vague. "I am writing to formally resign" is perfect. "I've been thinking about my future" is not a resignation.
2. Your last day of work. Work this out from your contractual notice period. Our notice period calculator will give you the exact date.
3. Your notice period. State how much notice you're giving and confirm it meets your contract.
4. A quick thank you. Even if the job was awful, one line of gratitude costs you nothing and protects your reference.
5. An offer to help with handover. Optional, but it goes down well.

What NOT to Include

• Why you're leaving. You don't owe anyone an explanation. Keep it neutral.
• Complaints. A resignation letter is not the place. Save it for the exit interview, if there is one.
• Where you're going. You don't need to share this. And frankly, mentioning your new employer can sometimes trigger restrictive covenant headaches you don't want.
• Emotion. However bad the relationship with your manager has been, keep the tone measured and professional.
• Conditions or negotiations. A resignation should be clean and unconditional. If you want to negotiate something, do it in a separate conversation.

In many modern workplaces, resigning by email is perfectly acceptable and increasingly common. The content should be the same as a formal letter, but with an appropriate subject line.

Letter vs email: which should you choose?

This comes up a lot. The honest answer: it depends on where you work.

• Email works fine for most modern workplaces. If your manager works remotely or sits in another office, email is practical and gives you an instant, timestamped record.
• A physical letter still makes sense in traditional settings: law firms, civil service, senior positions. Some contracts specifically require "written notice," which might mean actual paper.
• The best approach? Tell your manager face to face first. Then follow up immediately with a written email or letter to make it official. That way nobody's blindsided and you've got your paper trail.

Common mistakes to avoid

Not checking your notice period

This sounds obvious, but people get it wrong all the time. Check your contract before you write the letter. Getting the end date wrong creates a mess with your final pay and holiday. Use our calculator to get the dates right.

Burning bridges

However much you hated the job, stay professional. The UK job market is smaller than you think, especially in specialist sectors. The manager you criticise in your resignation letter might be interviewing you at your next company in three years.

Forgetting outstanding issues

Before you resign, think about your unused holiday, any loans or advances from your employer, company property you need to return, and any restrictive covenants in your contract. Sort these out during your notice period. Chasing things after you've left is a pain for everyone.

Untaken statutory holiday is the one most often missed. Under regulation 14 of the Working Time Regulations 1998, your employer must pay you for statutory leave you have accrued in the current leave year but not taken by your leaving date. Statutory entitlement is 5.6 weeks a year, which is 28 days for a five-day week and may include bank holidays if your employer counts them that way. Work out how much of that you have used before you agree a leaving date.

Resigning before you have a written offer

A verbal promise from a new employer is not an offer you can rely on. Wait for the signed, written offer with a confirmed start date, and for any conditions such as references or right-to-work checks to be cleared. Then resign, not before.

After you've resigned

The letter's sent. Now what? A few things to keep in mind during your notice period:

• Keep doing your job properly. Coasting through your notice is obvious and it follows you
• Start writing handover notes. Document your responsibilities, ongoing projects, key contacts
• Check your remaining holiday. Discuss with your manager whether you'll take it or be paid for it
• Return company kit: laptop, phone, passes, whatever they've lent you
• Make sure HR has your correct address for your P45 and final payslip
• Stay on good terms with everyone. Everyone

Your notice period is the last thing people remember about you. Make it count. A smooth exit gets you a good reference, keeps your network intact, and lets you start your next role with a clear conscience.
