UK Holiday Entitlement UK: Your Complete Employee Guide

Right, let's get to grips with what you're legally owed when it comes to paid time off in the UK. The law is crystal clear on this: almost every worker is entitled to 5.6 weeks of paid holiday each year.

For most of us working a standard five-day week, that works out to a solid 28 days of paid annual leave. This isn't just a company perk; it's a fundamental legal right designed to ensure everyone gets a proper break from work.

Understanding Your Core Holiday Entitlement in the UK

Think of your annual leave as a mandatory recharge. It’s there to help you rest, prevent burnout, and strike a healthier work-life balance. The moment you start a new job, you begin building up this entitlement—it’s not something you have to wait a year to earn.

The rules, laid out in the Working Time Regulations 1998, are built around this core principle of 5.6 weeks. This entitlement accrues with every hour you work, starting from your very first day. While employers have some say in how you take your leave, they absolutely cannot give you less than this legal minimum.

To get a deeper understanding of the nuts and bolts, you can read our in-depth guide to calculating holiday entitlement.

Let's break down the minimum legal requirements in a simple table.

| UK Statutory Holiday Entitlement at a Glance | | :--- | :--- | :--- | :--- | | Entitlement in Weeks | Equivalent in Days (Full-Time) | Includes Bank Holidays? | Legal Basis | | 5.6 weeks | 28 days | Often, but not always. Check your contract. | Working Time Regulations 1998 |

This table shows the absolute baseline. Many employers offer more generous packages, but they can never offer less than what's legally required.

What the 28-Day Standard Means for Full-Time Staff

Talking about holiday in 'weeks' can feel a bit abstract. It’s often easier to think in days. If you work a typical five-day week, the calculation is simple: 5 days × 5.6 weeks = 28 days.

But here’s a really important detail: this 28-day figure can, and often does, include bank holidays. How your employer handles this should be spelled out in your contract.

There are generally two ways they can approach it:

• Inclusive: Your contract might state you get 28 days of annual leave, and you have to book bank holidays from this allowance if you want them off.
• Exclusive: Alternatively, it could specify you get 20 days of leave plus the 8 public holidays, which still adds up to the minimum 28 days.

Of course, a more generous company might give you 28 days on top of the bank holidays. The golden rule is to always check your contract—it’s the definitive guide to your personal entitlement.

Your employment contract is the final word on how your leave is structured. It must clearly state your total days off and explain whether bank holidays are part of your statutory 28 days or an added extra.

How You Start Earning Your Holiday

You don't have to wait until you've worked a full year to get your holiday. You start earning it from the moment you clock in on day one.

This process is called 'accrual'. Essentially, you build up your holiday allowance throughout the year. For every month you work, you earn one-twelfth of your total annual entitlement. This system ensures fairness, especially if you leave a job part-way through the year—your employer must pay you for any holiday you've accrued but haven't yet taken.

Calculating Holiday for Part-Time and Irregular Hours

Figuring out holiday for a full-time employee on a standard five-day week is pretty straightforward. But what about the millions of people working part-time, on shifting patterns, or with zero-hour contracts? Fairness is everything, and UK law makes sure everyone gets their statutory 5.6 weeks of paid leave. It just needs to be calculated in a different way. This is where pro-rata calculations come in.

Think of "pro-rata" as simply scaling the full-time allowance to fit a different work schedule. It ensures someone working three days a week gets the same proportion of holiday as their full-time colleagues. It's the cornerstone of keeping things fair across the entire workforce.

This image breaks down how you can convert different work patterns into a holiday allowance, whether you're counting in days or hours.

As you can see, no matter if an employee has set days or completely variable hours, there's a clear method to work out what they're owed.

Calculating Holiday for Part-Time Employees

For staff who work a fixed number of days each week, just fewer than five, the maths is simple multiplication. You just multiply the number of days they work by the statutory 5.6 weeks.

The formula is a breeze: (Days worked per week) x 5.6 = Total annual holiday days

Let's run through a couple of real-world examples to see it in action.

• Example 1: A 3-Day Week An employee works every Tuesday, Wednesday, and Thursday. Calculation: 3 days × 5.6 weeks = 16.8 days of paid holiday per year.

• Example 2: A 4-Day Week Another team member works Monday to Thursday. Calculation: 4 days × 5.6 weeks = 22.4 days of paid holiday per year.

You might be looking at those decimal points and wondering what to do. Employers often round up to the nearest half or full day for everyone's sanity, but they aren't legally required to. The one thing they absolutely cannot do is round down. For a deeper dive into more complex scenarios, check out our simple UK guide on how to calculate pro-rata holidays.

Tackling Irregular Hours and Zero-Hour Contracts

Things get a little more complex for workers who don't have a fixed schedule, like those on zero-hour contracts or with wildly variable shifts. Since their hours can change week by week, we need a different approach to ensure they still get their fair holiday allowance.

For these situations, the holiday entitlement is calculated based on the hours they’ve actually worked. The go-to method uses a specific percentage to figure out how much holiday time they've accrued.

The magic number for calculating holiday for irregular hours is 12.07%. This isn't just plucked out of thin air; it comes from the 5.6 weeks of statutory leave divided by the remaining 46.4 working weeks of the year (52 weeks - 5.6 weeks = 46.4).

This means for every single hour someone works, they earn a small slice of paid holiday time. It’s a fair system that links their time off directly to the time they put in.

To calculate the holiday they've earned (in hours), you simply multiply the total hours they worked in a period by 12.07%.

• Formula for Irregular Hours: (Total hours worked) x 12.07% = Holiday hours accrued

Let’s use a practical example. Imagine a student working at a pub on a zero-hour contract. Last month, they clocked up a total of 60 hours.

• Their holiday accrual for that month would be: 60 hours × 0.1207 = 7.24 hours of paid leave.

This accrual method means that the more they work, the more holiday they earn. It's a transparent, fair, and legally sound way to manage leave for the most flexible members of your team, no matter how unpredictable their schedule might be.

How Bank Holidays Affect Your Annual Leave

Here’s something that catches a lot of people out: bank holidays are not an automatic, paid day off for everyone in the UK. It might feel like a national perk, but legally, there's no right to have them off.

How bank holidays are handled comes down to one thing and one thing only: your employment contract.

An employer is perfectly within their rights to include bank holidays within your statutory 5.6 weeks of annual leave. The critical part is that this must be clearly laid out in your contract. When Easter or Christmas rolls around, that document is the single source of truth for what you’re entitled to.

Decoding Your Contract Wording

The precise phrasing of your holiday allowance in your contract can make a world of difference to your total time off. Two sentences that look almost identical can have wildly different outcomes.

Here’s a practical breakdown of how different wording can affect a full-time employee:

As you can see, those little words—"inclusive" and "plus"—are incredibly important. The first two examples both meet the legal minimum, just in different ways. The third example shows a more generous package, offering a significant benefit on top of the statutory requirement.

The phrasing in your contract is everything. "28 days inclusive of bank holidays" is very different from "28 days plus bank holidays." The first meets the minimum legal requirement, while the second is a significant additional benefit.

This gets especially tricky in years with unusual bank holiday patterns. For example, the leave year from 1 April 2024 to 31 March 2025 only has seven bank holidays because of when Easter falls. If a contract simply states "20 days plus bank holidays," an employee would only get 27 days off, which is less than the legal minimum. You can learn more about how to handle the 2025 leave year anomaly to ensure you remain compliant.

Fairness for Part-Time Workers

Handling bank holidays for part-time staff needs a careful and fair approach. Imagine a part-time employee who never works on a Monday. They would consistently miss out on the benefit of most bank holidays, which is clearly unfair compared to their full-time colleagues.

To fix this, employers must apply a pro-rata principle to the entire holiday entitlement, including the bank holidays. This ensures part-timers get a proportional allowance, no matter which days of the week they work.

For instance, someone working three days a week is entitled to 60% of a full-timer's holiday allowance (3 ÷ 5 days = 0.6). That 60% calculation should apply to the total pot of leave, bank holidays included.

If a bank holiday falls on their non-working day, they should get that time back as a pro-rated day off in lieu to use another time. This keeps everything fair and square, preventing what could be seen as discriminatory treatment under the Part-time Workers (Prevention of Less Favourable Treatment) Regulations 2000.

When Can You Take It? The Rules on Using and Carrying Over Leave

Knowing how much holiday you get is only half the story. The rules around when you can take it—and what happens if you don't—are just as crucial for both employees and employers.

Your annual leave isn't like a savings account you can dip into whenever you fancy. There are firm regulations in place to make sure it's used for its intended purpose: giving you a proper break to rest and recharge.

The law is very clear on this: you can't be paid in place of taking your statutory holiday. The only time this is allowed is when you leave your job. The whole system is built to promote a healthy work-life balance throughout the year, not to give you a cash bonus.

The "Use It or Lose It" Rule

At its core, UK holiday entitlement operates on a "use it or lose it" basis. Think of your leave year as a bucket that's refilled every 12 months. The expectation is that you empty most of that bucket before it gets topped up again.

Specifically, the first four weeks of your statutory holiday (which comes from the EU's Working Time Directive) absolutely cannot be carried over into the next leave year. This part is non-negotiable.

This rule is all about health and safety. It's there to stop people from working for years on end without a substantial break, which is a fast track to burnout and poor mental health.

By law, the first four weeks of your annual leave are for rest and recovery within the year they're given. Employers have a duty to make sure their staff are not just able, but encouraged, to take this time off.

What about the remaining 1.6 weeks? Well, these (along with any extra leave your company offers) can sometimes be carried over, but only if you have a clear, written agreement with your employer.

When Can You Carry Leave Over?

While the "use it or lose it" principle is pretty strict, the law isn't heartless. It recognises that life sometimes gets in the way of a well-earned holiday.

You are legally allowed to carry over some or all of your statutory 5.6 weeks of leave into the next leave year if you were unable to take it for specific reasons:

• You've been off on long-term sick leave. If you were too ill to take your holiday, you can carry forward up to four weeks of unused leave for up to 18 months after the end of the leave year it was accrued in.
• You've been on statutory family leave. This covers maternity, paternity, adoption, or shared parental leave. Any holiday you couldn't take while you were away can be rolled over to the next leave year.

These protections are vital. They ensure you aren't penalised for being ill or for taking time off to grow your family.

How to Book Your Time Off

The exact process for requesting a holiday should be laid out in your employment contract or company handbook. It’s pretty standard practice to give your employer a decent amount of notice.

A good rule of thumb is to give notice that’s twice as long as the holiday you want to take. So, if you're planning a week off, you need to put in your request at least two weeks beforehand.

But can your boss say no? Absolutely. They can refuse a holiday request if there's a good business reason, like a clash with a key project deadline or too many other team members already being off. They do, however, have to give you a proper reason and make sure you have other opportunities to take your leave. Keeping track of all this can be a real headache, which is why many companies start looking into HR systems for small business to make life easier.

Your employer can also tell you when to take your holiday. This often happens in businesses that have a company-wide shutdown, like closing the office between Christmas and New Year. If they do this, they must give you enough notice—again, at least double the length of the time they're asking you to take off.

What Happens to Holiday During Sickness or Family Leave?

Life happens. Whether it's a long-term illness or welcoming a new family member, extended time off work is a reality for many of us. This often raises a big question: what happens to my annual leave? Thankfully, UK law is very clear on this – your right to paid holiday is protected.

Let's get straight to it: you continue to build up (or 'accrue') your statutory holiday entitlement even when you're off sick. It doesn't matter how long you're away; your leave accumulates exactly as if you were at your desk. This protection is a core part of UK employment law, recognising that sick leave is for recovery, while annual leave is for rest and relaxation. They serve two completely different purposes, and you shouldn't lose out on one because of the other.

Can I Use Holiday While on Sick Leave?

If you find yourself on sick leave, you're in the driver's seat when it comes to your holiday. You can absolutely choose to take paid holiday during your sickness period. Why would you do this? Well, if you're only receiving Statutory Sick Pay (SSP), you might decide to book some annual leave to top up your income with your normal holiday pay.

However, your employer cannot make you take annual leave while you're signed off. That decision is entirely yours. Many people prefer to save their accrued holiday and take it once they're back at work, giving them a chance for a proper, restorative break when they're well enough to enjoy it.

The crucial thing to remember is that you control your annual leave during sick leave. You can use it for financial stability or save it for when you've recovered. Your employer has to respect that choice.

What if a long-term illness means you can't use all your holiday within the leave year? The law has you covered. You have the right to carry over up to four weeks of unused statutory leave. You must use this carried-over leave within 18 months from the end of the leave year in which it was accrued.

Holiday Accrual During Family Leave

These protective rules aren't just for sickness; they extend to statutory family leave as well. Your holiday pot keeps filling up throughout any period of:

• Maternity Leave: You'll build up your full entitlement during both Ordinary and Additional Maternity Leave.
• Paternity Leave: Taking paternity leave has no effect on your holiday accrual.
• Adoption Leave: Just like maternity leave, your holiday accrues as normal.
• Shared Parental Leave: Both parents continue to build up their holiday entitlement while on shared parental leave.

This principle makes sure that taking crucial time to care for your family doesn't mean sacrificing your right to paid rest and time off later on.

It's quite common for new parents to return to work with a hefty amount of holiday built up. Since you often can't use this before the leave year ends, the law allows you to carry all of it over to the next year. It’s a great idea to chat with your employer and agree on a plan for using this leave before you come back. You could use it to create a phased return by working shorter weeks for a while, or simply book a well-deserved, longer holiday later in the year.

Frequently Asked Questions About Holiday Entitlement

Getting to grips with the ins and outs of your holiday entitlement can throw up a few tricky questions, especially when your work situation changes. Let's clear up some of the most common queries that pop up about annual leave.

We’ll break down what happens to your holiday when you leave a job, whether your boss can actually tell you when to take time off, and how your holiday pay should be worked out so you aren't left short.

What Happens to My Holiday if I Leave My Job?

When you hand in your notice, you're legally entitled to be paid for any statutory holiday you've earned but haven't used. This is actually one of the very few situations where an employer is allowed to pay you instead of you taking the time off.

The calculation is done on a pro-rata basis. For example, if you leave your job exactly six months into the company's leave year, you’ll have earned half of your total annual entitlement. From that figure, your employer will subtract any holiday you’ve already taken and pay you for whatever is left in your final payslip.

Can My Employer Tell Me When to Take My Holiday?

In short, yes, they can. While it might not always feel fair, your employer does have the right to dictate when you take some or all of your annual leave. This is quite common in businesses that have a company-wide shutdown, like many manufacturing firms do over Christmas or for summer maintenance.

They can’t just drop it on you at the last minute, though. Your employer must give you proper notice, which needs to be at least double the length of the holiday they're asking you to take. So, if they want you to take one week off, they have to tell you at least two weeks beforehand.

Your employer can also refuse a holiday request, but they need a good business reason for it – maybe it clashes with a critical project deadline or another team member is already off. Even so, they still have to make sure you have a reasonable chance to take your full entitlement before the leave year is up.

How Is My Holiday Pay Calculated?

This is a big one. Your holiday pay must reflect what you normally earn in a week. It’s not just about your basic salary; it has to include other regular payments you get as part of your job.

A series of legal rulings have made it clear what "normal pay" really means, making sure you're compensated properly. This means your holiday pay should almost always take into account:

• Regular overtime: If you consistently work extra hours and get paid for them, this has to be factored in.
• Commission: Any money you earn through commission schemes is part of your normal pay.
• Bonuses: Certain bonuses, especially those directly linked to your performance, should also be included in the calculation.

The whole point is to ensure you don't end up out of pocket just for taking the holiday you're legally entitled to.
