This article demystifies the holiday accrual system, offering you a fresh perspective on this crucial aspect of employee management.
What is holiday accrual?
Holiday accrual is a system that allows employees to earn paid time off from work based on the number of hours they work. It is an essential aspect of employment that determines how much holiday time an employee is entitled to and how this holiday time is paid.
In the UK, holiday entitlement is governed by statutory and contract laws. The statutory minimum holiday entitlement is 28 days per year for full-time employees, which includes bank holidays.
However, many contracts and company policies provide additional holiday time. It is essential for employees to be aware of their holiday entitlement and for employers to ensure that they are meeting their obligations.
How holiday accrual works
In a holiday accrual system, annual leave a year is typically accrued based on the hours an employee works. For example, an employee working a full-time schedule of 40 hours per week may accrue two weeks of holiday time per year, while an employee working part-time may accrue holiday time on a pro-rata basis.

This pro-rata calculation considers the work hours a staff works compared to a full-time schedule so that part-time employees are entitled to a proportional amount of holiday time. The holiday entitlement is calculated where the full year's holiday allowance is calculated based on the work hours.
To calculate accrued holiday, employees may be able to carry the holiday leave time to the following year, but they must use their accrued holiday time on time. Employees may be entitled to be paid for new statutory leave time if they leave work. This pay-out is typically calculated based on the employee's average pay over 12 weeks.
Holiday entitlement laws in the UK
Holiday entitlement Laws within the UK stand today; full-time employees are eligible to receive a minimum of 28 days of leave per year. Adding on any other bank holidays, these individuals will have an array of days off throughout the year. Importantly, these laws apply to workers regardless of their employment status; be it part-time, casual etc.
The calculation for part-time staff is then carried out pro-rata based on their hours compared to a full-time employee. Consequently, Leave Entitlement Laws to provide flexible support to various kinds of working individuals living in the UK.
What is pro-rata holiday entitlement?
Pro-rata holiday entitlement is the amount of leave year an employee is entitled to based on their work hours compared to a full-time schedule. For example, if staff works a part-time schedule of 20 hours per week, they may be entitled to half the holiday time of a full-time employee working 40 hours per week. This is because their work schedule is half the size of a full-time schedule, so their total annual leave is also half the size.
Pro-rata holiday entitlement is calculated on a percentage basis, based on the number of hours an employee works compared to a full-time schedule. For example, if a full-time employee is entitled to 28 days of holiday per year, and staff works a part-time schedule of 20 hours per week, they would be entitled to 14 days of holiday per year (28 days x 20 hours/40 hours = 14 days).
Pro-rata holiday pay entitlement ensures that part-time staff are entitled to a proportional amount of holiday time based on the number of hours they work. It is an essential aspect of employment for both employees and employers to understand, as it determines how much holiday time an employee is entitled to and how this holiday time is paid.
Managing holiday accrual
Managing holiday accrual is an essential job for both employers and employees. Employees should keep track of their holiday year, as it's possible to become entitled to additional days off if the annual leave provided doesn't cover the whole year.
Employers can help facilitate this by providing a system for tracking employee holiday accruals, such as a holiday accrual spreadsheet or software, to ensure all employees have their entitlement accurately accounted for. Managing holiday time wisely can save everyone hassle further down the line and prevent misunderstandings or disputes over how much holiday an employee is entitled to.
What if an employee leaves with an accrual deficit?
Employees who leave their job with an accrual deficit may be entitled to be paid for unused holiday time. This pay-out is typically calculated based on the employee's average pay over 12 weeks. Employers are responsible for accurately tracking and paying out holiday accrual for their employees to ensure they receive their full entitlements.
Employers may have different policies for leave pay for employees who work irregular hours or shift patterns. It is important for these employees to understand how their holiday pay is calculated and to keep track of their holiday accrual.
Other types of leave
In addition to holiday time, there are other types of leave that employees may be entitled to, such as:
- Sick leave
- Parental leave
- Adoption leave.
Maternity leave is a statutory right for expectant mothers, and some employers may also offer paternity leave for fathers. It is essential for employees to understand their entitlements and for employers to have policies in place for these types of leave.
