How Much Holiday Pay Are You Entitled To?

In the UK, almost all workers are legally entitled to a minimum of 28 days of paid annual leave each year — that's 5.6 weeks, including bank holidays. The question isn't whether you're entitled; the law is clear on that. The real question is: how much is that worth in pounds, and how do you calculate it for your specific work pattern?

This guide walks you through the calculation, shows you what happens to unused days, and covers the scenarios that make holiday pay trickier — part-time work, zero-hours contracts, and what happens when you leave a job.

How Much Is 28 Days Worth?

The simplest way to calculate your holiday pay is:

Holiday pay = (gross daily rate) × (days of holiday taken)

Your gross daily rate = (annual salary) ÷ (working days per year)

Example: Full-time employee, £35,000/year

• Working days per year: 260 (52 weeks × 5 days)
• Gross daily rate: £35,000 ÷ 260 = £134.62
• 28 days of holiday: £134.62 × 28 = £3,769.23

So your statutory entitlement is worth £3,769.23 per year — that's the cost to your employer if you take all 28 days. Spread across 12 months, it's roughly £314/month added to your salary if you actually use your full entitlement.

According to the UK government's holiday entitlement guidance, employers can include bank holidays (8–10 days per year in the UK) as part of your 28-day allowance. So "28 days including bank holidays" is the legal minimum, not a bonus — a job advertising "25 days plus 8 bank holidays" is meeting the legal minimum, not offering extra.

The critical insight: you're entitled to 5.6 weeks of paid time off, based on your normal working pattern. For full-time 5-day workers, that's 28 calendar days. For everyone else, it's calculated differently.

Part-Time, Zero-Hours, and Irregular Contracts

If you don't work standard 9–5 Monday–Friday, your entitlement is calculated pro-rata based on your actual hours.

Example: 3-day-a-week employee, £15,000/year

• Working days per year: 156 (52 weeks × 3 days)
• Gross daily rate: £15,000 ÷ 156 = £96.15
• 28 days entitlement × £96.15 = £2,692/year
• But you don't take 28 calendar days — you take 28 ÷ 5 × 3 = 16.8 calendar days (3.36 weeks)

The 28-day figure is shorthand for full-time workers. What matters is 5.6 weeks of your hours.

For zero-hours and variable-hours contracts, the calculation is messier. You're entitled to 5.6 weeks' worth of paid time off based on your average hours and pay over the last 12 weeks.

Example: Zero-hours worker, average 20 hours/week

• 12-week average: 240 hours
• 5.6 weeks × 20 hours = 112 hours of annual holiday
• At £12/hour: 112 × £12 = £1,344/year

This is why calculating holiday pay for part-time workers can feel opaque — you're working with averages. If you're unsure, ACAS (the Advisory, Conciliation and Arbitration Service) has a detailed holiday-pay calculator and guidance, and it's free to use.

What Happens to Days You Don't Use?

This is where holiday entitlement becomes a money issue — and where workers often lose out.

Rolling over unused holiday: Your employer can choose whether to let you carry unused days into the next year. There's no legal requirement, but many contracts allow it (often with a limit: "carry over max 5 days"). If your employer doesn't permit carryover and you don't take your 28 days by December 31st, those days are gone. No payment, no carry-over. They're lost. This is why taking your full entitlement matters.

Pay in lieu when you leave: If you resign or are made redundant, you must be paid for any accrued holiday you haven't taken — including unused days in the current year, even if your employer normally doesn't allow carry-over. This is a statutory right.

Example: You resign in August, having taken 14 days

• Days accrued in 8 months: 28 × (8/12) = 18.67 days
• Days owed: 18.67 − 14 = 4.67 days
• At £134.62/day: 4.67 × £134.62 = £629

This should appear as a lump sum on your final payslip. If your employer is dragging their feet on a final payment, that's a breach of statutory rights — escalate to ACAS or your local Citizens Advice office.

Contractual holiday (more than 28 days): Some employers offer 25 days plus 8 bank holidays, or a flat 30 days. The statutory 28-day minimum still applies, but anything above that is contractual. You can't lose contractual holiday (unless it's not taken and carryover isn't allowed), and you're paid for it if you leave. Check your employment contract for the exact policy.

Holiday Pay and Your Tax Position

Here's the part that trips people up: holiday pay is taxed as ordinary income. There's no special holiday-pay tax or exemption.

When your employer pays you for your 28 days off, it counts toward your annual taxable income. If you earn £35,000 and take 28 days of holiday (£3,769), your total annual income is £38,769 — subject to the same tax and National Insurance as any other salary.

If you bunch your holiday into one month, you might temporarily move into a higher tax band, but the annual effect is the same as spreading it across the year.

This matters if you're close to a tax threshold. If you earn £48,000 and take a £3,769 bonus and 28 days of holiday in the same month, you're briefly over the £50,270 higher-rate threshold — though the year-end tax calculation will even it out.

Understanding how your salary, pension contributions, and other deductions affect your take-home pay helps you plan big bonus or holiday-heavy months. The same logic applies: pension contributions reduce your taxable income, so they can help offset the tax impact of taking a lot of holiday at once.

Special Scenarios

Shift workers and night-shift employees: You get 28 days statutory entitlement. Your daily rate is calculated based on your normal shift pattern, including any shift premium. So if you normally work nights and earn a 15% premium, your holiday pay includes that premium.

Apprentices: Same 28-day entitlement, but apprentices earn near minimum wage (currently £12.30/hour or less), so the annual cash value is smaller.

Starting mid-year: You accrue holiday as you work. Start in June, and you're entitled to pro-rata holiday for the 7 months remaining in the year. Some employers front-load your full 28 days immediately; others accrue month-by-month.

Maternity, paternity, and sick leave: You continue to accrue your 28 days while on statutory leave. You can't lose it because you're not working. The math is complex if you're off for several months — check our guide to statutory sick pay or ask your HR team.

Redundancy: Redundancy pay and accrued holiday are separate. You get paid for both on your final payslip — the redundancy lump sum plus any unused holiday accrued to your leaving date.

Frequently Asked Questions

Q: Can my employer force me to take holiday at specific times? A: Yes. Your employer can require you to take holiday, and they can choose when — though they must give reasonable notice (typically double the length of the holiday period; so to take 2 weeks off, they'd give 4 weeks' notice). In practice, most workplaces agree on holiday dates with you.

Q: What if I've been off for 6 months and haven't been given any holiday? A: This breaches your statutory rights. Raise it with your employer in writing. If they don't resolve it, contact ACAS or lodge a claim with an Employment Tribunal. You're entitled to back-pay for accrued holiday.

Q: If I'm paid monthly, is my holiday entitlement affected? A: No. Your entitlement is still 28 days, and your daily rate is calculated as (annual salary) ÷ 260. Whether you're paid weekly, monthly, or annually doesn't change the calculation.

Q: Can my employer pay me the cash value of my holiday instead of letting me take the days? A: Only with your agreement. The statutory entitlement is a right to take time off, not a cash substitute. If your employer offers extra holiday allowance on top of the 28 statutory days, that can sometimes be taken as cash — but check your contract.

Q: I'm on an annualised hours contract. How does holiday work? A: On annualised hours (where your salary is spread evenly across 12 months but actual hours vary), your holiday entitlement is still 5.6 weeks × your average weekly hours. Your contract should specify how your employer calculates this.

Q: What happens to my holiday if I change from full-time to part-time mid-year? A: Your entitlement for the year is pro-rated based on each period. If you were full-time for 6 months (14 days accrued) and part-time for 6 months (7 days accrued at the reduced rate), you have ~21 days total for the year. Your contract should clarify how the switch is handled.

Q: Is statutory holiday the same as "bank holidays"? A: No. Your 28-day entitlement includes bank holidays. It's not 28 days plus the 8–10 bank holidays in the UK. Some countries use different terms — the US, for example, doesn't have a statutory holiday entitlement; employers offer it voluntarily. The UK law is 28 days total, inclusive of bank holidays.
