Annual Leave Rights in the UK: 28 Days Explained

The UK's Leave System at a Glance

Every worker in the United Kingdom is entitled to 5.6 weeks of paid annual leave per year. For someone working a standard five-day week, that works out to 28 days.

That number places the UK comfortably above the United States, which has no statutory paid leave at all, and roughly in line with the EU Working Time Directive's minimum of 20 days. But there is an important detail that catches many people off guard: those 28 days include bank holidays.

In England and Wales there are 8 bank holidays each year. Most employers count them as part of the 28-day entitlement, which means you actually get 20 days to schedule yourself and 8 days dictated by the calendar. In practice, if your contract says "20 days plus bank holidays," you are getting exactly the statutory minimum presented in a friendlier way.

That 28-day floor applies to all workers, not just full-time permanent employees. Part-time workers, agency workers, and even those on zero-hours contracts are covered. The entitlement is simply adjusted pro rata based on how much you work.

Your contract may offer more than 28 days, but it can never offer fewer. Any clause that reduces your entitlement below the statutory minimum is unenforceable under the Working Time Regulations 1998.

How Does the UK's Leave Entitlement Work?

Who qualifies?

Everyone classified as a "worker" in UK employment law is entitled to paid annual leave. This includes:

• Full-time employees on permanent contracts
• Part-time employees
• Workers on fixed-term contracts
• Agency workers (from day one of the assignment)
• Zero-hours contract workers
• Casual and irregular-hours workers

The only people excluded are genuinely self-employed contractors who are not classified as workers. If your employer controls when, where, and how you do your work, you are almost certainly a worker regardless of what your contract says.

Accrual from day one

Leave begins accruing from your first day of employment. There is no qualifying period. During your first year, you build up leave month by month at a rate of one-twelfth of your annual entitlement per month worked. After that first year, your full entitlement is available at the start of each leave year.

Pro-rata calculations for part-time workers

If you work fewer than five days per week, your entitlement is calculated proportionally. The formula is straightforward:

Weekly working days x 5.6 = annual leave entitlement (in days)

Part-time workers who happen to work on a day that falls on a bank holiday are entitled to have it counted as leave. If a bank holiday falls on a day you would not normally work, your employer is not required to give you a substitute day off, though many do.

The 12.07% method for irregular hours

For workers with no fixed hours, such as those on zero-hours contracts, holiday pay is calculated using the 12.07% method. This figure comes from dividing 5.6 weeks of leave by the remaining 46.4 working weeks in the year (52 minus 5.6).

In practice, this means for every hour worked, 12.07% of that hour accrues as paid holiday. Some employers roll this into hourly pay as "rolled-up holiday pay," though this practice has a complicated legal history and is only formally permitted under the most recent legislative changes for irregular-hours and part-year workers.

What Are the Carry-Over and Expiry Rules?

This is where UK leave law gets surprisingly nuanced.

The default position

Under the Working Time Regulations, there is no automatic right to carry unused leave into the next leave year. If your employer's policy says "use it or lose it," that is generally lawful for the additional 1.6 weeks (8 days) above the EU-derived minimum of 4 weeks (20 days).

However, the first 4 weeks (20 days) of entitlement, which derive from the EU Working Time Directive (retained in UK law post-Brexit), have stronger protections. If you were genuinely unable to take this leave, for example due to sickness or maternity leave, those days must carry over.

What your contract might say

Many employers are more generous than the statutory minimum. Common contract terms include:

• Carrying over up to 5 days into the next year
• A "use by" deadline, often 3 to 6 months into the new leave year
• Buy-back or sell-back schemes that let you exchange unused days for pay (or buy extra days)

Always check your specific contract and employee handbook. The statutory rules are a floor, not a ceiling, and your employer's policy may differ significantly in either direction.

Sickness during booked leave

If you fall ill during a period of booked annual leave, you can reclaim those days as sick leave instead, preserving your annual leave entitlement. You will typically need to follow your employer's sickness reporting procedure and may need a GP's note. This rule comes from EU case law (the Pereda ruling) that the UK has retained.

The COVID carry-over exception

During 2020 and 2021, emergency regulations allowed workers to carry over up to 4 weeks of unused leave into the following two leave years if COVID-19 prevented them from taking it. Those provisions have now expired, but they set an important precedent and some employers have adopted more flexible carry-over policies permanently as a result.

Do People in the UK Actually Use Their Leave?

The short answer: not as much as they should.

Research from various HR platforms and employment surveys consistently shows that UK workers leave an average of 4 to 6 days of annual leave unused each year. A 2023 survey by People Management found that nearly a third of UK employees did not take their full entitlement.

The presenteeism problem

British workplace culture has long rewarded visibility. Even before remote work became widespread, studies found that many employees felt taking their full leave would be viewed negatively by managers or colleagues. This is sometimes called "leave guilt," the nagging feeling that taking time off means letting the team down.

The irony is well documented. Workers who take regular breaks are more productive, more creative, and less likely to burn out. Skipping leave does not make you a better employee; it makes you a more exhausted one.

Remote work has blurred the lines

Since 2020, the rise of hybrid and fully remote work has made the problem worse in some ways. When your home is your office, "switching off" requires more deliberate effort. Many remote workers report checking emails or attending quick calls during leave days, turning what should be genuine time off into a half-working limbo.

The solution is not complicated, but it does require intention. Block your calendar, set an out-of-office reply, and actually close your laptop. Your 28 days exist for a reason.

What Are the Bank Holidays in the UK for 2026?

England and Wales observe 8 bank holidays per year. Here are the dates for 2026:

Boxing Day falls on Saturday 26 December in 2026, so the substitute bank holiday moves to Monday 28 December. Combined with Christmas Day on Friday, this creates a natural four-day weekend without using any discretionary leave, running from Friday 25 December through Monday 28 December.

Scotland and Northern Ireland

Scotland observes 9 bank holidays, adding St Andrew's Day (30 November). In practice, Scottish employers often substitute 2 January (a traditional Scottish holiday) for one of the other dates.

Northern Ireland observes 10 bank holidays, adding St Patrick's Day (17 March) and the Battle of the Boyne / Orangemen's Day (13 July) to the England and Wales list.

Easter 2026 is particularly well placed for leave planning. With Good Friday on 3 April and Easter Monday on 6 April, taking just 4 days of leave (30 March to 2 April) gives you 10 consecutive days off. That is a 2.5x return on your leave days.

How Does the UK Compare to Other Countries?

One of the most common misconceptions about the UK's 28-day entitlement is that it is one of the most generous in the world. It is decent, but context matters. The UK's 28 days include bank holidays in the statutory count, while most other countries list leave days and public holidays separately.

Here is how the numbers actually compare:

When you strip out the accounting differences, the UK's effective entitlement of 20 discretionary days plus 8 bank holidays is middle-of-the-pack for Western Europe and well ahead of the US and most of East Asia. But it falls noticeably behind France, the Nordics, and Spain.

Make Every Day Count

Twenty discretionary days is not a lot. But the way you place them on the calendar matters enormously. A single day off next to a bank holiday Monday can give you a four-day weekend. Four well-placed days around Easter can turn into ten days off.

The difference between a good leave year and a great one is not how many days you have. It is whether you use them at the moments where they multiply. Understanding how holiday bridges work is the first step, and running your specific situation through an optimiser is the second.
