UK Regulations – for Staff and employees

UK Statutory Entitlement

Full-time workers in the UK are entitled to a minimum of 28 days of paid holiday per year. The government referred to this entitlement as "Statutory". Public holidays can be included as part of the 28 days to which you are entitled.

Information for Part-Time Workers

Generally, if you work fewer than 5 days per week it can be classified as part-time. Part-time workers are entitled to Statutory leave but it's calculated based on the days or hours worked per week and will be fewer than the full 28-day allowance.

Leaving or Starting Mid-way Through a Working Year

Similar to the part-time workers, if you leave or start mid-year, then the allowance is calculated accordingly and will be fewer than the full 28-day entitlement of allowance.

Carrying Over Days or Time Off in Lieu

An employer will usually agree with their staff on how many days can be carried over. There isn't however a legal requirement except in the scenario where sickness or maternity prevented the employee from taking their full entitlement, this would permit up to 20 days of the entitlement to be carried over to the next working year.

Leave Allowance Greater than the Statutory Required

Statutory leave entitlement does not cover any additional days the employer may have chosen to provide you in addition to the minimum legal statutory entitlement.

Use our annual leave entitlement calculator to find out the annual leave allowance for employees who work part-time or started part way through the year.
