How to Hand in Your Notice in the UK — Complete 2026 Guide

Handing in your notice is one of the most stressful moments in your career — and one of the easiest to get wrong. Resign incorrectly and you could lose holiday pay, breach your contract, or burn a reference you might need later.

This guide walks you through exactly how to hand in your notice in the UK, step by step. We'll cover notice period lengths, how to write your resignation letter, the legal rules, and the costly mistakes most people make.

Step 1: Check Your Employment Contract

Before you do anything else, dig out your employment contract or offer letter. Your contract will state your exact notice period — and this overrides the statutory minimum if it's longer.

Look for a section titled "Termination" or "Notice Period." It will typically say something like: "You are required to give one month's written notice to terminate your employment."

If you can't find your contract, ask HR for a copy. Under UK law, your employer must have given you a written statement of employment within two months of your start date.

Key point: Your contractual notice period and the statutory minimum are different things. You must give whichever is longer.

Step 2: Understand Your Statutory Notice Period

UK employment law sets minimum notice periods based on how long you've worked for your employer. Even if your contract doesn't mention notice, these statutory minimums apply:

Example: If you've worked somewhere for 5 years, the statutory minimum is 5 weeks. But if your contract says 3 months, you must give 3 months — because it's the longer of the two.

Most office-based and salaried roles in the UK have a contractual notice period of one month, though senior positions often require three months or more.

Step 3: Write Your Resignation Letter

Your resignation letter doesn't need to be long or emotional. In fact, the shorter and more professional it is, the better. A good resignation letter should include:

• A clear statement that you are resigning — don't be ambiguous
• The date you're submitting it — this determines when your notice period starts
• Your intended last working day — based on your notice period calculation
• A brief thank-you — keeps things professional
• An offer to help with handover — protects your reference

Avoid writing paragraphs about why you're leaving, complaints about management, or emotional appeals. Keep it factual and polite. This letter may end up in your HR file and could be referenced in future employment checks.

Important: Your notice period starts the day after you submit your resignation, not on the day you hand it in. This is a common mistake that can push your last day back by one day.

Step 4: Submit Your Notice Properly

How you submit your resignation matters. Follow these rules:

• Put it in writing. A verbal resignation is technically valid in the UK, but it's far harder to prove and can lead to disputes about dates. Always follow up in writing.
• Tell your manager first. Before emailing HR, have a face-to-face (or video) conversation with your direct manager. It's professional courtesy and avoids blindsiding them.
• Email a copy to HR. After speaking to your manager, send the written letter to HR (and CC your manager). This creates a paper trail with a timestamp.
• Keep a copy for yourself. Save the email in a personal folder or take a photo. You may need proof of when you submitted it.

Step 5: Work Your Notice Period

Once your notice is accepted, you're expected to work your full notice period unless your employer agrees otherwise. During your notice period:

• You must continue working as normal and fulfilling your duties
• Your employer must continue paying you as normal
• You still accrue holiday entitlement
• Your employer can ask you to take unused holiday during your notice period
• In some cases, your employer may put you on "garden leave" — you stay employed but don't come in

Can your employer make you leave early? Yes. They can offer "payment in lieu of notice" (PILON), which means they pay you for the notice period but you leave immediately. Check your contract to see if there's a PILON clause.

Common Mistakes When Handing in Your Notice

These are the errors we see most often — and they can cost you money, your reference, or both.

1. Only resigning verbally

A conversation with your boss saying "I'm leaving" is easy to misremember. Without a written record, there's no proof of when your notice period started. Always put it in writing on the same day you have the conversation.

2. Getting the dates wrong

Your notice period starts the day after you hand in your letter, not the same day. If you resign on Monday, your notice starts on Tuesday. Getting this wrong by a single day can push your last day into a new week — and potentially a new month.

3. Not checking your holiday balance

Many employees don't realise they have unused holiday days when they resign. Under UK law, you're entitled to be paid for any accrued but untaken holiday. However, if you've taken more holiday than you've accrued, your employer can deduct the overpayment from your final pay.

4. Forgetting about restrictive covenants

Your contract may contain non-compete or non-solicitation clauses that restrict what you can do after leaving. Review these before you resign, especially if you're joining a competitor or starting your own business.

5. Burning bridges

It's tempting to say what you really think in your resignation letter or during your notice period. Don't. Your current employer is a future reference. Stay professional, deliver a solid handover, and leave on good terms.

The Holiday Pay Trap: What Most People Miss

This is the single biggest financial mistake people make when resigning, and it's shockingly common.

When you leave a job, your employer should pay you for any unused holiday you've accrued. But here's the problem: many employers undercount your accrued holiday or quietly deduct days you're entitled to.

Under the Working Time Regulations 1998, you accrue 5.6 weeks of paid holiday per year (28 days for full-time). This accrues proportionally — so if you leave halfway through the year, you should be paid for 14 days minus whatever you've already taken.

The mistake most people make? They don't include the right wording in their resignation letter. Without explicit reference to your holiday pay entitlement, some employers will process your final pay without a full holiday reconciliation.

We've seen people lose anywhere from £400 to £2,000+ because their resignation letter didn't include a holiday pay protection clause. It's completely legal for you to include this — and it puts your employer on notice that you expect a full and accurate payout.

Frequently Asked Questions

Can I resign by email?

Yes. There's no legal requirement to resign on paper in the UK. An email counts as written notice. However, check your contract — some employers require a hard-copy letter delivered to a specific person or department.

Can I take holiday during my notice period?

Yes, you can request holiday during your notice period. Your employer can also require you to take remaining holiday during notice. Any untaken holiday must be paid out in your final pay packet.

What if my employer asks me to leave immediately?

If your employer wants you to leave before your notice period ends, they must either pay you in lieu of notice (PILON) or place you on garden leave. They cannot simply stop paying you and send you home — that would be a breach of contract.

Can I withdraw my resignation?

There is no automatic legal right to withdraw a resignation once it has been given. However, your employer may agree to let you stay. The sooner you ask, the better your chances. Once they've started recruiting your replacement, it becomes much harder.

What happens if I don't work my notice period?

If you leave before your notice period ends without agreement, you're technically in breach of contract. Your employer could (in theory) sue for damages, though this is rare for most roles. More realistically, you'll get a poor reference. The safest approach is to negotiate an early release date if needed.
