Notice Period Rights in the UK Explained

Your notice period is the amount of warning that must usually be given before employment ends. In the UK, the answer is not always just “one week” or “one month”. The real answer depends on both statutory notice and your contract.

Statutory minimum notice from an employer

If you are dismissed and have been employed for at least one month, the legal minimum is usually:

• 1 week after one month up to two years of service
• 1 week for each full year of service from two years up to twelve years
• 12 weeks maximum once you reach twelve years of service

If your contract gives more than that, the contractual notice usually applies instead.

Notice you must give when resigning

Employees normally have to give at least one week if they have worked for one month or more, unless the contract requires longer. Many contracts set resignation notice at one month or more for office-based, management, or specialist roles.

Contractual notice can beat the legal minimum

The rule of thumb is simple: if the contract gives you more than the statutory minimum, the contract usually wins. If the contract gives you less than the statutory minimum from the employer’s side, the legal minimum still applies.

This matters most when people assume the handbook summary is the whole contract. Always check:

• your signed contract
• later variation letters
• promotion letters
• any collective agreement wording that may have been incorporated

When does notice actually start?

This is where many leaving-date disputes happen. Notice usually starts when it is clearly communicated. If your contract requires written notice, an employer may create risk by relying on a casual verbal statement alone.

You should also check whether the contract says notice must expire on:

• a particular weekday
• the end of a pay period
• the end of a calendar month

Those details can shift the final date significantly.

Garden leave and pay in lieu

Some employers ask you not to work during notice. That can happen in two main ways:

• Garden leave: you remain employed and paid during the notice period but do not actively work.
• Payment in lieu of notice (PILON): the employer ends employment sooner and pays instead of requiring you to work the notice.

The contract often decides whether PILON is straightforward or potentially controversial.

What to check before agreeing your last day

Before you confirm a leaving date, make sure you know:

• how much notice applies
• when notice legally started
• whether the contract changes how notice is counted
• whether bank holidays, annual leave, or garden leave affect the practical handover
• whether bonus or commission rules depend on still being employed on a certain date

Practical next step

Use the Notice Period Calculator to test the start date, service length, and notice type. It is a quick way to sense-check whether the date your employer gave you lines up with the legal minimum and your contract wording.

Step-by-step checklist

1

Find the rule that applies

Start with your contract, then compare it with the statutory minimum notice under the Employment Rights Act to see which one gives you more protection.

2

Confirm the start date of notice

Your leaving date depends on when valid notice was actually given, not just when the conversation happened.

3

Check what happens during notice

Notice can be worked, paid in lieu, or spent on garden leave depending on the contract and what the employer chooses to do lawfully.
