Annual Leave During Notice Period: Rights, Refusals, and Remedies

The statutory annual leave notice period in the UK is twice the length of the leave you want to take: five days off requires ten days’ notice, two weeks off requires four weeks’ notice. That is the default set by Regulation 15 of the Working Time Regulations 1998.¹ It applies only when nothing else is agreed. Most employment contracts and staff handbooks set their own timelines, and where they do, the contract wins.

How the Statutory Formula Works

Regulation 15 sets a simple rule. The notice you give must be at least twice as many days as the number of days you want off. A one-week holiday needs two weeks’ notice. A two-week break needs four weeks’ notice. The clock runs in calendar days, counted backward from the first day of the proposed leave.¹

Miss the deadline and your employer can turn the request down without giving any further reason. That is where a lot of leave disputes start, because a worker who submits a request even one day late has no statutory ground to insist on the time. Keep a written record of when you submitted, whether that is an email timestamp or a date on an internal system. If a disagreement reaches a formal stage, the burden of proving you gave proper notice sits with you.

The rule applies the same way regardless of whether you work full-time, part-time, or on a zero-hours contract. Days requested multiplied by two equals minimum notice. There is no discretion built into it.

When Your Contract Overrides the Default

Most employers do not rely on the statutory default. They write their own leave notice requirements into employment contracts, staff handbooks, or internal policies. A contract might require a flat 30 days’ notice for any holiday longer than three days, or it might be more relaxed than the statute and let you book a day off with 48 hours’ warning.

Regulation 15(5) explicitly allows this. Where a “relevant agreement” governs when leave is taken, the statutory notice formula does not apply.¹ A relevant agreement can be an individual employment contract, a collective agreement negotiated by a recognised trade union, or a workforce agreement made between the employer and employee representatives. If any of these sets its own leave-booking procedure, that procedure replaces the double-notice default entirely.

Read your contract and handbook before you assume the statutory formula is what governs your request. In most workplaces, it is not, because almost every employer has some kind of written leave policy. If you genuinely cannot find one, the statutory default fills the gap automatically.

Can Your Employer Refuse Your Request?

Yes, but not without a deadline of their own. Regulation 15 requires the employer to give counter-notice equal to the length of leave that was requested. If you asked for four days off, your manager must tell you “no” at least four days before the leave was due to start.¹

The two sides of the equation are not symmetric. You need double the time to request leave. Your employer needs only a one-to-one ratio to refuse it. A manager who waits until the day before to reject a two-week holiday request has not met the legal deadline. In that situation, the refusal has arrived too late to have legal effect, and you may be entitled to take the leave as originally planned.

Walking out after a late refusal is risky in practice. A tribunal might support your position, but the workplace consequences of unilateral action can be severe. The safer move is to flag the late refusal in writing and, if the employer still insists, take the dispute through a formal grievance or tribunal rather than not showing up.

When Your Employer Can Make You Take Leave

Employers can tell you when to take your leave, not just whether to approve a request you have made. This commonly happens during Christmas shutdowns, factory maintenance periods, or other times when partial staffing is impractical. The notice requirement mirrors the employee rule: the employer must give notice of at least twice the length of the compulsory leave period. A one-week shutdown requires two weeks’ advance notice to the workforce.¹

The notice must specify which days the business will close and the total leave that will be deducted from each worker’s annual entitlement. Those shutdown days come out of your own leave balance, not from a separate employer pot. If your company shuts for two weeks at Christmas, that is two weeks of your annual entitlement spoken for before you book anything yourself.

An employer who fails to give the required double-notice cannot lawfully force you to use your leave for the closure. Most businesses announce shutdowns months in advance, which easily satisfies the requirement. Problems tend to arise when a closure is announced at short notice.

Notice for Leave During a Resignation or Dismissal Notice Period

When you resign or are dismissed, your remaining statutory leave does not vanish. You can take whatever is left of your entitlement during your notice period.² The same notice rules apply. You still need to give twice the length of the leave you want, and your employer can still counter-refuse with notice equal to the leave period.

An employer can also require you to use up remaining leave during your notice period, using the mandated-leave provisions, provided they give the required double-notice. If your notice period is only two weeks and you have ten days of leave remaining, the arithmetic gets tight. If you have already taken more leave than your pro-rated entitlement by the time you leave, your employer generally cannot deduct the overpayment from your final pay unless that was agreed in writing beforehand.²

If the Rules Are Broken

If your employer refuses leave you are entitled to, or forces leave on you without proper notice, you can bring a complaint to an employment tribunal under Regulation 30 of the Working Time Regulations.³ The tribunal can declare that your rights were breached and award compensation it considers “just and equitable” based on the employer’s failure and any financial loss you suffered.

There is no fixed formula for the award. It is not automatically a day’s pay per day of lost leave, though that outcome is common when the loss is straightforward. The tribunal weighs the circumstances, including whether the employer acted deliberately or made an administrative error. Complaints must generally be filed within three months of the date the employer refused the leave or failed to pay what was owed.³
