UK Statutory Annual Leave Calculator
How UK Holiday Entitlement Works
In the UK, almost all workers are legally entitled to 5.6 weeks of paid annual leave per year, known as statutory leave entitlement. This applies to full-time, part-time, agency workers, and those with irregular hours or part-year contracts.
Key Point: For workers on a standard 5-day week, 5.6 weeks equals 28 days of paid holiday per year. This is the statutory minimum that employers must provide.
The statutory entitlement is capped at 28 days, regardless of how many days you work per week. For example, someone working 6 or 7 days per week is still only entitled to 28 days unless their employer offers more.
Statutory Leave Components
The 5.6 weeks entitlement comprises two elements:
- 4 weeks derived from EU Working Time Directive
- 1.6 weeks additional leave under UK domestic law
Employers may choose to include the 8 UK bank holidays within the 28-day statutory minimum, or offer them in addition to the statutory entitlement. This must be clearly stated in the employment contract.
Calculation Methods Explained
Full-Time Workers
Maximum: 28 days (statutory cap applies)
Example: A worker on a 6-day week receives 6 × 5.6 = 33.6 days, but capped at 28 days
Part-Time Workers
Part-time workers receive the same entitlement as full-time workers, calculated on a pro-rata basis according to the days they work.
| Days Worked Per Week | Calculation | Entitlement (Before Rounding) | Entitlement (Rounded Up) |
|---|---|---|---|
| 5 days | 5 × 5.6 | 28.0 days | 28 days |
| 4 days | 4 × 5.6 | 22.4 days | 22.5 days |
| 3 days | 3 × 5.6 | 16.8 days | 17 days |
| 2 days | 2 × 5.6 | 11.2 days | 11.5 days |
| 1 day | 1 × 5.6 | 5.6 days | 6 days |
Irregular Hours and Part-Year Workers
From 1 April 2024, workers with irregular hours or part-year contracts accrue holiday based on hours actually worked, using the 12.07% accrual method.
Rationale: 5.6 weeks holiday ÷ 46.4 working weeks (52 – 5.6) = 12.07%
Holiday accrual = 120 × 12.07% = 14.48 hours (14 hours 29 minutes)
Pro-Rata for Joiners and Leavers
When workers join or leave partway through the holiday year, their entitlement is calculated proportionally.
Formula for Leavers: ((Full annual entitlement ÷ 12) × Months worked) – Days already taken = Remaining entitlement
Pro-rata entitlement = (28 ÷ 12) × 7 months = 16.33 days → Rounded up to 16.5 days
Example – Leaver: Employee leaves 1 July, has taken 10 days, full entitlement 28 days
Accrued entitlement = (28 ÷ 12) × 6 = 14 days
Remaining entitlement = 14 – 10 = 4 days owed in final pay
Bank Holidays Explained
There are 8 permanent bank holidays in England and Wales (Scotland and Northern Ireland have variations):
- New Year’s Day
- Good Friday
- Easter Monday
- Early May Bank Holiday
- Spring Bank Holiday
- Summer Bank Holiday
- Christmas Day
- Boxing Day
Employer’s Choice: Employers can choose whether to include bank holidays within the 28-day statutory minimum or offer them as additional leave. Many employers include them within the statutory entitlement, whilst others offer 28 days plus bank holidays (36 days total).
For part-time workers, bank holidays are treated proportionally. If a part-time worker doesn’t work on the day a bank holiday falls, they don’t need to use a holiday day. However, if required to work on a bank holiday, they should receive a day off in lieu or have it counted within their pro-rata entitlement.
Holiday Pay Rates
Workers must receive their normal pay for holiday periods. The calculation depends on work patterns:
Fixed Hours and Salary
Workers with fixed hours or annual salary receive their normal weekly or monthly pay during holiday.
Variable Hours and Commission
For workers whose pay varies (including commission, overtime, or shift allowances), holiday pay is calculated as an average over the previous 52 weeks of actual work. Weeks where no work was done are excluded from the calculation.
Recent case law has confirmed that regular payments such as commission, regular overtime, and shift allowances must be included in holiday pay calculations for the first 4 weeks of annual leave (EU-derived entitlement).
Carrying Over Holiday
The rules on carrying over unused holiday depend on the type of leave:
Standard Position
Employers can set their own rules about carrying over the 1.6 weeks of additional UK leave (8 days for full-time workers). Many employers have “use it or lose it” policies for this portion.
EU-Derived Leave (4 Weeks)
Workers who couldn’t take the 4 weeks of EU-derived leave due to sickness, maternity, or being prevented by the employer may carry it forward. This carried-over leave can potentially accumulate over multiple years.
COVID-19 Provisions
Special regulations allowed carrying over up to 4 weeks of unused leave for 2 years if it couldn’t be taken due to coronavirus. These provisions have now expired, but carried-over leave from that period may still exist.
Common Scenarios
Starting a New Job
Holiday entitlement begins accruing from your first day of employment. You may need to complete a probationary period before taking holiday, but you’re entitled to accrue it during this time. Upon starting, calculate your pro-rata entitlement based on the remaining months in your employer’s leave year.
Leaving a Job
When employment ends, you’re entitled to payment for any accrued but untaken holiday. Calculate the days accrued up to your leaving date, subtract days already taken, and you’ll receive payment for the balance. If you’ve taken more holiday than accrued, employers can deduct this from final pay only if stated in your contract.
Sickness During Holiday
If you fall ill during pre-booked holiday and follow your employer’s sickness reporting procedures, those days can be reclaimed as sick leave rather than holiday. You’ll need to provide medical evidence for the period of sickness.
Maternity, Paternity, and Parental Leave
Holiday continues to accrue during maternity, paternity, adoption, and shared parental leave at the normal rate. Many employees take their accrued holiday immediately before or after their family leave to extend time with their child.
Zero-Hours Contracts
Workers on zero-hours contracts have the same holiday rights as other workers. Holiday accrues at 12.07% of hours worked. Employers must allow zero-hours workers to take their accrued holiday and cannot offer “rolled-up holiday pay” (paying a higher hourly rate instead of providing holiday).
Agency Workers
Agency workers are entitled to 5.6 weeks holiday per year, calculated using the same methods as direct employees. The agency (not the client company) is responsible for providing and paying for holiday entitlement.
