Working notice vs garden leave vs PILON

Most UK notice periods resolve in one of three ways. The calculator above gives you the date for the first; the table sets out how the other two compare.

Whether your contract gives the employer the right to use garden leave or PILON is set out in the notice clause — it’s worth checking before you assume either is on the table.

Notice periods in the UK — a practical guide

How is a notice period calculated?

A notice period runs from the day you hand in your resignation to the last day you’re contractually required to work. If your contract says “one month’s notice”, you add one calendar month to the date you resign — so handing notice in on 15 March gives a final working day of 15 April. Weeks work the same way: two weeks is fourteen calendar days, not ten working days.

When the notice is in months and the target month doesn’t have your start day (e.g. resigning on 31 January with one month’s notice), the convention is to roll back to the last day of the next month — 28 February in most years, 29 February in a leap year.

Do weekends count in a notice period?

Yes. Notice is measured in calendar time, so weekends and bank holidays are included. If your final day lands on a Saturday or Sunday, most employers treat the previous Friday as your last working day — but that’s a practical convention, not a legal rule. The toggle in the calculator above mirrors that approach.

What is the minimum notice period in the UK?

If you’ve been employed for one month or more, the statutory minimum notice you have to give is one week — even if your contract is silent on the subject. Employers, by contrast, owe you at least one week’s notice for each full year of service, up to a cap of twelve weeks after twelve years.

Most contracts ask for longer than the statutory minimum (typically one or three months), and the longer of the two periods applies. Senior roles often have three or six months written in.

Can your employer ask you to work longer?

Not unilaterally. Your notice period is whatever your contract says (or the statutory minimum, whichever is longer). An employer can’t simply extend it. They can, however, ask you to leave earlier and pay you for the unworked notice (a payment in lieu of notice, or PILON), or place you on garden leave — keeping you on the payroll but away from the office.

If you’d like to leave sooner than your contract allows, the best route is usually a polite conversation. Many employers will agree to a shorter notice period in writing if cover is in place.

What should you do after resigning?

Get written acknowledgement of your resignation and the agreed final working day. Check that any accrued holiday will be paid out, and ask when to expect your final payslip and P45. Tidy up handover notes early so the last fortnight isn’t a scramble, and line up references before access to work systems is removed.

If you don’t already have your next role lined up, give yourself a week to refresh your CV and shortlist roles before starting applications in earnest — the resources below are a decent starting point.
