Short answer
Your employer can refuse individual holiday requests, and can even require you to take leave at particular times or cancel leave already booked, provided the correct notice is given. What your employer cannot lawfully do is prevent you from taking your statutory minimum holiday altogether during the leave year. The two things are different: control over when you take leave is permitted, but denial of the entitlement itself is not.
Your statutory entitlement
Under the Working Time Regulations 1998, almost all workers are entitled to a minimum of 5.6 weeks’ paid annual leave per leave year. For someone working five days a week this is 28 days, which may include bank holidays depending on your contract. This is a legal floor. Your contract may give you more, but it cannot lawfully give you less than the statutory minimum. Your employer has a positive duty to ensure you are able to take at least your statutory leave within the leave year.
Refusing an individual request
Regulation 15 of the Working Time Regulations governs how leave is requested and refused. You give notice of the dates you want to take, and your employer can either accept it or serve a counter-notice refusing those specific dates.
The default notice rules, which apply unless your contract or a workforce agreement says something different, are:
1. To request leave, you must give notice of at least twice the length of the leave you want, so two days’ notice for one day’s leave.
2. To refuse a request, your employer must give you counter-notice at least equal to the length of leave requested. So if you ask for ten days, they must tell you no less than ten days before the leave was due to start.
An employer can lawfully refuse particular dates for genuine business reasons, for example staffing shortages, a busy period, or too many staff already off at the same time. So refusing a specific request, or several specific requests, is not in itself unlawful.
The crucial limit: they cannot deny the entitlement itself
There is a clear difference between refusing particular dates and refusing to let you take any statutory holiday at all. An employer cannot lawfully block you from taking your 5.6 weeks over the whole leave year. If your employer refuses every request you make with the effect that you cannot use your entitlement before the year ends, that is a breach of the Regulations, regardless of how it is dressed up.
Employers also have obligations arising from case law to give workers a genuine opportunity to take paid leave and to warn them that untaken leave may be lost, otherwise the leave can carry over. This reinforces that the entitlement must be capable of being taken, not merely notionally available while every request is refused.
Requiring or cancelling leave
The flip side is that your employer can also require you to take leave on specified dates, for example a Christmas shutdown, by giving notice of at least twice the length of the leave. They can also cancel leave you have already booked, giving notice at least equal to the length of that leave. This can be frustrating, especially if you have already paid for a trip, but it is permitted provided the notice is correct. Whether they compensate you for financial loss is a matter of good practice and possibly contract rather than strict legal obligation.
What could explain the refusals
Before treating this as unlawful conduct, it is worth identifying which situation you are in, because the material facts change the answer:
If you have already booked all your leave for the year, further refusals are entirely lawful.
If the refusals relate to genuinely inconvenient dates, such as peak periods or when too many colleagues are already off, refusing those specific dates is lawful even if it happens repeatedly, so long as you are still left with a realistic opportunity to take your entitlement on other dates.
If the leave year is running out and your employer is refusing every date such that you will lose the entitlement, that is where the position tips into a likely breach.
If the refusals appear to target you specifically because of a protected characteristic such as disability, religion, pregnancy or race, or because you have asserted a statutory right, that could additionally amount to discrimination or a detriment, which is a separate and more serious matter.
Missing facts that affect the answer
To assess your position properly it would help to know how much leave you have left in the current year, when your leave year ends, what your contract or staff handbook says about booking and notice, the reasons your employer has given for the refusals, and whether all your colleagues are treated the same way or you are being singled out.
Practical steps
1. Check your contract, staff handbook and any holiday policy for the notice rules and any restrictions such as blackout periods, as contractual terms can lawfully displace the default statutory notice periods.
2. Work out how much statutory leave you still have and how many working days remain before the leave year ends. This tells you whether you are genuinely being prevented from taking your entitlement.
3. Submit clear written holiday requests giving the proper notice, and keep copies. Written requests create a record and force the employer to respond with proper counter-notice.
4. If requests keep being refused, raise it in writing, ideally referring to your right to take your statutory 5.6 weeks and asking the employer to confirm on which dates you will be permitted to take the remaining leave before the year ends. Keep it factual and non-confrontational.
5. If that does not resolve it, use the internal grievance procedure.
6. If it still is not resolved and you are being denied your statutory leave, you can bring a claim in the employment tribunal under the Working Time Regulations. There is a strict time limit, generally three months less one day from the date of the act complained of, and you must contact Acas for early conciliation first. Acas is also a good free source of advice and can help before matters reach that stage.
Bottom line
Your employer is allowed to say no to particular dates, and even to dictate or cancel dates with proper notice, but it is not allowed to refuse requests in a way that leaves you unable to take your statutory minimum holiday during the leave year. The key question is whether, taken as a whole, you are still being given a real opportunity to use your entitlement. If the year is running down and every request is being blocked, that is the point at which the refusals become legally vulnerable.
