How to handle holiday requests fairly and lawfully
There are statutory notice rules for booking leave, and matching ones for refusing it — both expressed as multiples of the leave itself. Most employers override them with a policy, which is allowed. Very few know what the default is if the policy is silent.

Key takeaways
- A worker gives notice of at least twice the length of the leave — 20 days’ notice for 10 days off
- To refuse or cancel leave, the employer gives notice at least as long as the leave requested, plus one day
- An employer can refuse a specific request but cannot refuse to let someone take their holiday at all across the year
- A contract or policy can set different notice rules — the statutory positions apply where it does not
The statutory notice rules
Where a contract or policy says nothing, the Working Time Regulations supply a default — and it is expressed as a multiple of the leave being requested rather than a fixed number of weeks.
| Action | Notice required | For 10 days' leave |
|---|---|---|
| Worker requests leave | Twice the length of the leave | 20 days |
| Employer refuses or cancels leave | Length of the leave, plus one day | 11 days |
| Employer requires leave to be taken | Twice the length of the leave | 20 days |
A contract or policy can set different rules, and most do — a standard "four weeks' notice for any request over three days" is far easier to administer than a formula. The statutory positions matter precisely when nobody wrote anything down, which is more often than employers expect.
Refusing and cancelling leave
A specific request can be refused, provided the notice above is given and there is a genuine business reason. Cancelling leave already approved works the same way, though it carries a cost the notice rules do not address: someone may have booked travel.
The limit on refusing
You cannot refuse holiday to the point where somebody is unable to take their entitlement at all. The obligation is not merely to permit leave when convenient — it is to make sure workers can actually take what they are entitled to during the year. A pattern of refusals that leaves someone with a large untaken balance in month eleven is the problem, not any single refusal.
Requiring leave on set days
Leave can be required on specified dates — the Christmas shutdown, the week the site closes for maintenance — with notice of at least twice the length of the leave. A three-day closure needs six days' notice as a bare minimum; announcing it months ahead is both lawful and considerably better received.
Where a shutdown consumes a large share of the entitlement, say so in the contract or policy from the outset. Staff who discover in October that half their leave was already committed have a legitimate grievance, even where the notice was technically correct.
Peak periods and competing requests
In hospitality, retail and care, the dates everyone wants off are the dates you can least afford to lose cover. The failure mode is not the refusal itself — it is refusing without a rule anyone can see, which makes every decision look personal.
- Set the rule before the season — first come first served, rotation year on year, or a cap per team. Publish it.
- Cap by role, not just headcount — three people off is fine unless all three are the only keyholders.
- Decide in the order received and record when each request arrived, so the order is demonstrable.
- Watch for indirect discrimination — a blanket refusal across a period that coincides with a religious festival needs more justification than a rota preference.
- Answer quickly — a request sitting unanswered for three weeks is a decision made by default, and usually the wrong one.
Visibility does most of the work here. When approving a request shows who else is already off and whether the shifts are still covered, the answer arrives in minutes and the reason is obvious to everyone. Where it means cross-checking a spreadsheet against a rota against an inbox, requests queue — and the queue is what generates the complaints.
Carry-over and the year-end scramble
Carry-over rules differ between the four weeks derived from EU law and the additional 1.6 weeks, and a contract can be more generous than either. Untaken leave caused by long-term sickness is treated differently again. The detail sits in our holiday entitlement guide.
The operational point is simpler: a rush of requests in the final weeks of the leave year is a symptom of not tracking balances during it. If people can see what they have left in month four, the December pile-up mostly does not happen — and the balance you eventually pay out when someone leaves is the same number, calculated the same way, as covered in final pay when someone leaves.
RosterElf's holiday management keeps requests, approvals and remaining balances against the same rota the shifts live on, so an approval shows its consequences before it is granted — and the free holiday entitlement calculator works out the starting figure for anyone whose hours are not fixed.
Approve leave knowing the shift is still covered
Requests, approvals and remaining balances against the live rota — so the answer takes a minute and the reason is visible.
This guide summarises the statutory position on booking and refusing annual leave and is not legal advice. Contracts and policies commonly vary the notice rules. Check GOV.UK or Acas, or take advice, before relying on it in an individual case. It does not constitute legal, HR, or professional advice and should not be relied on as a substitute for advice specific to your business, workforce, or circumstances.
Holiday request questions
- Under the statutory default, at least twice as many days as the leave being taken. Ten days off needs 20 days’ notice. Most employers set their own rule in a contract or policy, which then applies instead.
- At least as many days as the leave requested, plus one. Refusing a 10-day request needs 11 days’ notice. The same applies to cancelling leave that has already been approved.
- Yes, with proper notice and for a genuine business reason. What an employer cannot do is refuse holiday so consistently that the worker is unable to take their entitlement during the leave year — the obligation is to make sure they can take it.
- Yes. Leave can be required on specified days — a Christmas shutdown is the usual example — provided notice of at least twice the length of the leave is given. Announcing a shutdown in November for a week in December is cutting it fine.
