What Is a Notice Period?
A notice period is the amount of time an employee or employer must give before employment officially ends. During this period, the employee usually continues to work under the same terms and conditions while preparing for their departure or transition.
Notice periods are normally set out in your employment contract. If your contract doesn’t specify a notice period, statutory minimum notice rules may apply.

How Is a Notice Period Calculated?
Your notice period usually begins on the day after your notice has been received, unless your employment contract states otherwise.
The end date depends on:
- Your contractual notice period
- Whether your notice is measured in days, weeks or months
- Any agreed annual leave taken during the notice period
- Your normal working pattern
Statutory Notice Periods in the UK
If your employment contract doesn’t specify a notice period, statutory minimum notice generally applies.
For employees leaving a job:
- Employees who have worked for at least one month must normally give at least one week’s notice, unless their contract requires more.
For employers ending employment:
| Continuous Service | Minimum Notice |
|---|---|
| Less than 1 month | No statutory notice |
| 1 month to 2 years | 1 week |
| 2 to 12 years | 1 week for each complete year of service |
| 12 years or more | 12 weeks |
Your employment contract may provide a longer notice period than the statutory minimum.

Frequently Asked Questions
Does my notice period include weekends?
If your notice period is measured in calendar weeks or months, weekends are normally included unless your contract states otherwise.
Can my employer ask me to leave immediately?
Depending on your contract, your employer may place you on garden leave or make a payment in lieu of notice instead of requiring you to work your full notice period.
What happens if I don't work my notice period?
Leaving before completing your notice period could be a breach of your employment contract. Speak with your employer if you need to leave earlier.
Can I use annual leave during my notice period?
No. The calculator estimates your gross pay, which is your earnings before Income Tax, National Insurance, pension contributions or any other deductions are taken into account.
Can I use this calculator if I work part-time?
Yes, if your employer agrees or your contract allows it.
Does sick leave affect my notice period?
This depends on your contract and the circumstances. In many cases, your notice period continues while you are off sick.
