UK Notice Period Employment Law: Your Rights Explained for 2025/26

Your statutory notice period in the UK depends on how long you have worked for your employer. If you have been employed between one month and two years, the minimum notice your employer must give is one week. After two years, it rises to one week per complete year of service, capped at 12 weeks. Your employment contract may require longer.

This guide explains how notice periods work under UK employment law, how to calculate yours, what happens when contracts say something different, and what to do if your employer does not follow the rules. Use our notice period calculator to work out your entitlement from your start date, or read our UK notice period rights guide for detail on pay in lieu of notice and garden leave.

Statutory notice periods: the legal minimums

The Employment Rights Act 1996 sets minimum notice periods that employers must give employees when ending employment. These are sometimes called statutory notice periods. They apply regardless of what your contract says, though your contract can require the employer to give you more notice than the statutory minimum.

The rules are straightforward. If you have worked for your employer for at least one month but less than two years, you are entitled to one week's notice. From two years onwards, you get one week's notice for each complete year of continuous employment. The maximum statutory notice an employer must give is 12 weeks, which applies once you have 12 or more years of service.

These minimums only apply when the employer dismisses you. They do not apply if you are dismissed for gross misconduct, where the employer can terminate employment immediately without notice. Gross misconduct covers serious breaches such as theft, violence, or serious negligence, and the employer must follow a fair process before relying on it.

How to calculate your notice period

Calculating statutory notice is based on complete years of continuous employment, counted from your start date to your termination date. Partial years do not count as an extra week. If you started on 1 March 2020 and are dismissed on 15 June 2025, you have five complete years of service (March 2020 to March 2025) and are entitled to five weeks' statutory notice, not six.

Continuous employment is not broken by most short gaps or changes in role within the same organisation. If you were promoted, transferred to a different department, or had a brief period of lay-off, your service usually continues uninterrupted. A gap of more than one week between contracts with the same employer can break continuity, but this depends on the circumstances.

Our notice period calculator handles the arithmetic for you. Enter your employment start date and either your last working day or today's date, and it returns your statutory notice entitlement in weeks. It also shows the equivalent in working days if your contract specifies notice in days rather than weeks.

Worked examples

Someone employed for 8 months receives 1 week statutory notice. Someone with 3 years and 11 months of service receives 3 weeks, because only complete years count. Someone with exactly 7 years receives 7 weeks. Someone with 15 years receives 12 weeks, because that is the statutory cap regardless of how many additional years they have worked.

If you are trying to work out a one month notice period, that is 4 weeks and 2 days on a standard Monday to Friday pattern, or simply 4 weeks if your contract defines a month as four weeks. Many employment contracts specify notice in months rather than weeks, which is where the distinction matters. Statutory notice is always expressed in weeks.

Contractual notice: when your contract says more

Your employment contract can require your employer to give you more notice than the statutory minimum, but never less. A contract giving you one week's notice when you have five years of service would be void in that respect: the statutory five weeks would apply instead. A contract giving you three months' notice when you have five years of service is valid, and the longer contractual period applies.

Professional, managerial, and senior roles commonly have contractual notice of one to three months regardless of length of service. A marketing manager with four years of service might have a statutory entitlement of four weeks but a contractual entitlement of three months. In that case the employer must give three months.

Always check your contract, staff handbook, or offer letter for the notice clause. If it is silent on notice, only the statutory minimum applies. If it specifies a period, the longer of the statutory or contractual period is what you are entitled to.

Notice employees must give their employer

The statutory minimum notice an employee must give is simpler than the employer's obligation. If you have worked for at least one month, you must give one week's notice. There is no increase based on length of service on the employee side under statute alone.

Your contract almost certainly requires more. One month's notice is standard for many roles. Three months is common at senior levels. If your contract says you must give three months and you only give one, your employer could pursue you for breach of contract, though in practice most employers accept shorter notice rather than going to court.

During your notice period you remain employed and bound by your contract obligations. You are entitled to your normal salary and benefits. Your employer can require you to work, place you on garden leave, or pay you in lieu of notice instead of requiring you to work the full period.

Notice during redundancy

Redundancy does not change your statutory notice entitlement. If you are made redundant after six years of service, you are still entitled to six weeks' statutory notice (or whatever your contract requires if longer). Redundancy pay is a separate entitlement calculated under different rules and is not a substitute for notice.

Your employer can give notice and require you to work it, give notice and place you on garden leave, or dismiss you immediately and pay you in lieu of notice. All three options satisfy the notice obligation provided you receive the correct amount. If you are made redundant, you may also be entitled to statutory redundancy pay if you have at least two years of service.

For collective redundancies of 20 or more employees within a 90-day period, additional consultation requirements apply. The employer must consult for at least 30 days before the first dismissal takes effect (45 days for 100 or more redundancies). This consultation period runs alongside, not instead of, your individual notice entitlement.

Pay in lieu of notice and garden leave

Pay in lieu of notice (PILON) means your employer pays you the salary you would have earned during your notice period instead of requiring you to work it. This is common after redundancy announcements when the employer wants a clean break rather than having departing staff in the office for several weeks.

PILON is taxed as normal employment income, including income tax and National Insurance. Since April 2018, post-employment notice pay rules mean HMRC treats PILON as earnings even if your contract does not include a PILON clause. This closed a loophole where some payments in lieu were taxed more favourably.

Garden leave means you stay away from work during your notice period while remaining employed and receiving full pay. Your employer might use this for senior staff or anyone with access to sensitive information. Whether garden leave is permitted depends on your contract. Our UK notice period rights article covers PILON and garden leave in more detail.

Probationary periods and notice

During a probationary period, notice requirements are often shorter than after probation ends. Many contracts specify one week's notice during probation for both employer and employee, even if the standard notice after probation is one or three months. This is lawful provided the probationary notice is clearly stated in the contract.

If you are dismissed during your first month of employment, no statutory notice is required from either side. The one-month threshold is a hard cut-off under the Employment Rights Act 1996. After one month, the one-week statutory minimum kicks in for employer notice, even if you are still within a probationary period.

Probation does not affect your right to the national minimum wage, paid holiday, or protection from discrimination. It only affects notice periods and sometimes contractual benefits that are stated to begin after successful completion of probation.

Fixed-term contracts and notice

Fixed-term contracts that simply expire at the end of the agreed term do not require notice from either party, unless the contract says otherwise. If your employer ends a fixed-term contract before its expiry date without a fair reason, that may amount to unfair dismissal if you have two or more years of service.

Successive fixed-term contracts can create continuity of employment. If you have been on back-to-back fixed-term contracts for four years with the same employer, you may have four years of continuous service for notice purposes even though each individual contract was only 12 months long.

What to do if your employer breaches notice rules

If your employer dismisses you without giving proper notice and without paying in lieu, that is wrongful dismissal. It is a breach of contract, distinct from unfair dismissal which concerns the reason for the dismissal. You can claim the wages you should have received during your notice period.

Start by asking your employer for a written breakdown of how your final payment was calculated. Check whether they applied the correct notice period based on your length of service and contract terms. Use the notice period calculator to verify the statutory figure independently.

If you cannot resolve it directly, you can bring a claim to an Employment Tribunal for wrongful dismissal. The time limit is three months minus one day from the effective date of termination. For amounts above £25,000 you can alternatively pursue a claim in the civil courts, where the limitation period is six years. Given the shorter tribunal deadline, do not delay seeking advice from ACAS, Citizens Advice, or an employment solicitor.

ACAS early conciliation

Before bringing most Employment Tribunal claims, you must contact ACAS for early conciliation. This free service attempts to resolve disputes without a hearing and can extend the three-month time limit, but start the process well before the deadline.

Notice periods compared with Europe

UK notice periods are shorter than in many European countries. Germany, France, and the Netherlands typically require longer notice based on age and service, sometimes measured in months rather than weeks. Our notice period rights in Europe guide compares statutory notice across EU countries. The UK system gives employers more flexibility to end employment with shorter notice, which cuts both ways: less protection when dismissed, but shorter obligations when you resign.

Practical tips before you resign or accept dismissal

Before resigning, check your contract for the notice period you must give and any restrictions that apply during notice, such as non-compete clauses or obligations to return company property. Giving insufficient notice can damage your reference and, in rare cases, lead to a breach of contract claim.

If you are being dismissed, confirm whether the notice is statutory or contractual, whether you will be required to work it, and whether PILON or garden leave applies. Ask for the calculation in writing. If redundancy is mentioned, check whether you also qualify for statutory redundancy pay separately from your notice entitlement.

Keep records of your start date, any contract variations, and communications about your departure. These are essential if you later need to challenge the notice period applied. The notice period calculator gives you a quick baseline so you know what to expect before any conversation with HR.
