UK Notice Period Rules: Complete Guide for Employees and Employers (2026)
Leaving a job — or letting someone go — raises the same question almost immediately: how much notice does anyone actually have to give? Understanding UK notice period rules can save you from a costly dispute, whether you’re an employee planning your next move or an employer managing a departure. The rules come from two places: what the law requires as a minimum, and what your contract says on top of that.
This guide covers statutory notice periods, contractual notice, what happens when notice isn’t given, and the rules around payment in lieu of notice (PILON) — all in plain English, with worked examples. By the end, you’ll know exactly where you stand.

What Are UK Notice Period Rules?
A notice period is the minimum amount of time either party must give before ending an employment contract. In the UK, these rules are set out in the Employment Rights Act 1996 (ERA 1996), sections 86–91, which establish a legal floor — the least notice an employer or employee can give.
Your contract can improve on these minimums, but it cannot go below them. If your contract offers less notice than the statutory minimum, the statutory minimum automatically applies.
Example: Jess has worked at a marketing agency for three years. Her contract says the company only needs to give her two weeks’ notice. Under the ERA 1996, she’s entitled to three weeks (one week per year of service). Her contract clause is void — the law overrides it.
Notice periods apply differently depending on who is giving notice. The rules for employers are more generous to employees than the reverse. That asymmetry is intentional — it gives workers time to find alternative income.
How Do Statutory Notice Periods Work in the UK?
The statutory minimum notice an employer must give depends on how long you’ve been employed:
| Length of continuous employment | Minimum notice from employer |
|---|---|
| Less than 1 month | None (or terms of contract) |
| 1 month – 2 years | 1 week |
| 2 years | 2 weeks |
| 3 years | 3 weeks |
| 4 years | 4 weeks |
| 5 years | 5 weeks |
| 6 years | 6 weeks |
| 7 years | 7 weeks |
| 8 years | 8 weeks |
| 9 years | 9 weeks |
| 10 years | 10 weeks |
| 11 years | 11 weeks |
| 12+ years | 12 weeks (maximum statutory cap) |
The formula: one week of notice per complete year of service, up to a maximum of 12 weeks.
Employees giving notice only need to give a minimum of one week, regardless of how long they’ve worked there — unless their contract specifies more.
Worked example: Tom has worked at a logistics firm for six years and four months. He decides to resign. Tom only needs to give one week’s notice under statute, but his contract requires one month. The contract applies, so Tom gives one month. His employer, by contrast, would need to give Tom at least six weeks’ statutory notice if they were letting him go.
What Does UK Law Say About Notice Periods?
The Employment Rights Act 1996 is the primary legislation governing notice periods in England, Scotland, and Wales. Sections 86 to 91 set out the specific statutory minimums.
Key legal points you need to know:
Continuous employment is the clock that determines your entitlement. It starts from your first day and runs until the notice period begins. Career breaks, maternity leave, and most absences due to sickness do not break continuity.
Fixed-term contracts have slightly different rules. If a fixed-term contract expires naturally without renewal, no notice is technically required — but dismissal before the end date does trigger notice rights.
During the notice period, employees are entitled to their normal pay. This includes any contractual benefits — not just base salary. If your employer puts you on garden leave (you’re still employed but told to stay away), you must still receive full pay and benefits throughout.
Waiving notice is possible if both parties agree in writing. An employer cannot force you to waive your statutory notice rights, but you can choose to do so voluntarily. ACAS confirms this position and offers free guidance on disputes — call their helpline on 0300 123 1100.
What Is Payment in Lieu of Notice (PILON)?
Payment in lieu of notice (PILON) is a lump sum your employer pays you instead of requiring you to work through your notice period. Rather than coming in for another four weeks, you leave immediately and receive the equivalent pay.
Whether PILON is available depends on your contract. If your contract includes a PILON clause, your employer can invoke it as a right. If there is no PILON clause, your employer can still make a payment in lieu — but you must agree to it, and the tax treatment may differ.
How PILON is taxed (from April 2020 onwards): Under the rules introduced by Finance Act 2017 (amended and in force since 2020), all PILON payments are subject to income tax and National Insurance, regardless of whether the contract contains a PILON clause. The old exemption that allowed the first £30,000 to be tax-free no longer applies to the basic pay element.
Worked PILON example: Sonia earns £36,000 per year (£3,000 per month). She’s entitled to two months’ contractual notice. Her employer invokes the PILON clause and pays her £6,000 instead of having her work the notice. That £6,000 is subject to income tax and National Insurance in the normal way — it’s treated as earnings, not a termination payment.
Any genuine redundancy payment above the notice pay element may still qualify for the £30,000 tax-free allowance — but the notice pay portion never does.
Common Mistakes Employees and Employers Make With Notice Periods
Mistake 1: Assuming the contract always overrides the law. It doesn’t — not when it works against the employee. Contracts can exceed statutory minimums but cannot fall below them. Many employees don’t realise their written contract is unenforceable on this point, and simply accept less notice than they’re legally owed.
Mistake 2: Confusing “notice given” with “notice served.” Notice starts from the day it is properly communicated — not the day you decide you want to leave. If you hand in written notice on a Friday afternoon and your employer receives it Monday, some employers will argue Monday is the start date. Always confirm receipt in writing.
Mistake 3: Thinking garden leave doesn’t count as notice. Garden leave is a form of serving notice. Your employer is paying you to stay away, but the notice clock is still running. You cannot, for example, start a new job during garden leave without potentially breaching your contract.
Mistake 4: Employers not paying full benefits during notice. Statutory notice entitles employees to receive their full contractual pay — including pension contributions, car allowances, and other contractual benefits. Stopping these during the notice period is a potential breach of contract.
Mistake 5: Assuming summary dismissal (instant dismissal) is always unlawful. An employer can dismiss without notice in cases of gross misconduct — but this must be genuine gross misconduct, investigated properly, and handled fairly. Misusing instant dismissal to avoid paying notice is a common but costly mistake that frequently ends in employment tribunal claims.

Frequently Asked Questions
How much notice does an employer have to give in the UK?
The minimum is set by the Employment Rights Act 1996: one week’s notice for each complete year of continuous employment, starting from one week (after at least one month of service) up to a maximum of 12 weeks. Your contract may give you more. Whatever is greater — statute or contract — applies.
Do I have to work my notice period?
Not necessarily. Your employer may agree to let you leave early, or they may invoke a PILON clause and pay you instead. If neither party agrees to cut the notice short, you are expected to work it. Leaving without working your notice is technically a breach of contract, though employers rarely sue employees for this in practice.
Can my employer dismiss me during my notice period?
Yes — but only for gross misconduct. If you are dismissed for any other reason during your notice period, you may still be entitled to the pay you would have received for the rest of it. Take legal advice or contact ACAS on 0300 123 1100 if this happens.
Is a notice period the same as a probation period?
No. These are separate things. A probation period is a trial phase at the start of employment where either party can often leave with shorter notice. A notice period applies throughout employment. Once probation ends, your full contractual notice period kicks in — though statutory minimums apply from day one.
Does a zero-hours contract come with a notice period?
Zero-hours workers who have been employed for at least one month are entitled to the same statutory notice minimums as any other employee — one week’s notice from the employer after one month, rising with length of service. This is a common misconception: the casual nature of the contract does not remove statutory notice rights.
