UK notice period guide

How much notice do I need to give to leave my job?

If you have worked for your employer for at least one month, the legal minimum is usually one week's notice. Your employment contract can require more. Use the calculator above to compare statutory and contractual notice, then plan the last day, final pay, holiday, P45, and employer leaver admin.

Quick answer for employees

Check your contract or written statement first. If it gives a longer notice period than the legal minimum, the contractual notice is normally the amount you need to give.

  • Less than one month: usually no statutory notice unless your contract or agreed terms require it.
  • At least one month: usually at least one week's notice.
  • Contract says more: use the contract, or agree a shorter date with your employer in writing.
  • Notice start date: unless the contract says otherwise, notice usually starts the day after you resign.

How it works

How the notice period calculator works

  1. 1. Choose who is giving notice. The statutory minimum is different for employee resignations and employer-led termination.
  2. 2. Add service and contract details. The tool calculates statutory notice, converts the contract value, and compares the two.
  3. 3. Estimate the final employment date.Notice usually starts the day after notice is given, so the result shows the notice start date and final employment date.

Employee resignation notice

Resigning employees should confirm how much notice they are giving, the expected last working day, and whether any holiday will be used or paid. Written notice is safest because it gives both sides a clear date trail.

Employer leaver admin

Employers should confirm the resignation in writing, tell the employee their notice period, agree the last day, close off holiday and final pay, and make sure payroll, P45, records, and access changes are handled on time.

What to check before the final day

If you are leaving a job

  • Contract notice period and whether notice must be in writing.
  • Expected final employment date and handover expectations.
  • Holiday you want to take during notice or holiday owed in final pay.
  • When you will receive final pay, payslip, and P45.

If you manage leavers

  • Written resignation, notice period, and agreed last working day.
  • Holiday balance, deductions, expenses, benefits, and final payroll cut-off.
  • Whether the employee works notice, takes holiday, receives PILON, or is put on garden leave.
  • Document retention, P45, employee access, and offboarding tasks.

Notice Period Calculator — FAQ

Understand your obligations and rights regarding notice periods in the UK.

How much notice do I need to give to leave my job?

If you have worked for your employer for at least one month, you must usually give at least 1 week's notice to resign unless your contract requires more.

Do I need to give notice if I have worked less than one month?

If you have worked for less than one month, there is usually no statutory notice requirement unless your contract, written statement, or agreed terms say otherwise.

What if I do not have a written contract?

If there is no written contract and no notice period has been agreed, employees who have worked for at least one month should usually give at least 1 week's notice.

When does the notice period start?

GOV.UK guidance says the notice period usually runs from the start of the day after notice is given. This calculator follows that convention when estimating the final employment date.

Can I leave before my notice period ends?

You can ask your employer to agree a shorter notice period. If they do not agree and you leave early anyway, you may be breaching your contract.

Can I use holiday during my notice period?

You can ask to take holiday during your notice period, but your employer can decide whether to approve it. Untaken statutory holiday should usually be paid when you leave.

What are PILON and garden leave?

PILON means payment in lieu of notice. Garden leave means the employee remains employed and paid during notice but is told not to work for some or all of that period.

Is this legal advice?

This calculator is for general payroll and HR planning. Contracts, settlement agreements, gross misconduct, redundancy rules, and local policies can change the final position.
