Understanding statutory holiday entitlement is a key responsibility for UK employers. Paid annual leave is one of the most important rights for employees and mistakes in calculating or granting it often lead to disputes and employment tribunal claims. By getting holiday entitlement right, you can stay compliant with employment law and protect your business from costly errors.
Under the Working Time Regulations 1998, most workers in the UK are entitled to a minimum of 5.6 weeks of paid annual leave each year. This entitlement applies to employees, agency workers and those on irregular hours or zero-hours contracts. For someone working a standard five-day week, this equates to 28 days. Employers can choose to include the eight UK bank holidays within this entitlement or offer them in addition.
For part-time staff, statutory holiday entitlement is pro-rated based on the number of days or hours worked. Casual and zero-hours workers also accrue holiday based on hours worked.
These rules apply regardless of whether an employee has a permanent, temporary or casual contract. Employers cannot offer less than the statutory minimum though they can provide more generous contractual entitlements if they wish.
Getting holiday entitlement calculations right is critical. Here are some common scenarios:
Holiday entitlement should be calculated on a pro-rata basis. For example, if a full-time employee working five days per week is entitled to 28 days, a part-time employee working three days a week is entitled to 16.8 days (3 ÷ 5 × 28).
From 1 January 2024, holiday pay and entitlement for irregular and part-year workers is based on 12.07% of hours worked, simplifying the previous system. Employers must ensure payroll systems are updated accordingly and that staff are clearly informed about how their entitlement is calculated.
Shift workers are also entitled to 5.6 weeks, calculated based on their normal shift pattern. Employers must ensure records are accurate to avoid underpayment or disputes.

Holiday pay should be based on a worker’s normal remuneration and not just basic pay. Courts have ruled that regular overtime, commission and allowances must be included in holiday pay calculations. Employers who fail to include these risk unlawful deduction claims.
Holiday pay must be paid at the time leave is taken and not rolled into hourly wages. Employers should keep detailed records and ensure payroll systems are compliant with the latest case law and government guidance.
In most cases, statutory holiday entitlement must be taken during the leave year. However, exceptions include:
Carried-over leave must normally be used within 18 months but employers should always check contracts and policies for specific rules.
Employers have a legal duty to:
Common pitfalls include miscalculating entitlement for part-time or zero-hours staff, failing to include overtime or commission in holiday pay and refusing carry-over where it is legally required. These errors frequently lead to tribunal claims for unlawful deductions from wages.
Example 1: A retail worker regularly worked overtime but the employer only paid basic pay for holidays. The employee brought a claim and was awarded compensation for unpaid holiday pay going back several years.
Example 2: A zero-hours worker was told they had no holiday entitlement. After seeking advice, they successfully claimed 12.07% of all hours worked as paid leave leading the employer to update contracts across the business.
Example 3: A part-time employee was denied bank holidays on the basis they did not work Mondays. The employer later learned entitlement must be pro-rata across the year not restricted to specific days.
Beyond simply complying with the law, employers can reduce risk and improve employee satisfaction by adopting best practices such as:
