Calculate your pro-rata annual leave entitlement as a part-time worker

ℹ️ The statutory minimum is 5.6 weeks for all workers. For part-timers this is pro-rated by working days or hours.

Common Questions

Do I get the same holiday rights as full-time colleagues?

Yes — in proportion to your hours. The Part-Time Workers (Prevention of Less Favourable Treatment) Regulations 2000 require that part-time workers receive equivalent holiday entitlement to a comparable full-time colleague, pro-rated by the proportion of full-time hours worked. An employer cannot simply give a part-time worker fewer weeks' leave than a full-timer.

How should bank holidays be treated for part-time workers?

Bank holidays in the UK count towards the 5.6 weeks statutory minimum. This creates a potential inequality for part-time workers who don't work certain days — if all 8 bank holidays fall on Monday but you only work Tuesday to Thursday, you lose out. Good practice is to give all workers a pro-rata allocation of bank holidays in addition to their leave entitlement, ensuring fairness regardless of the days worked.

Can unused holiday be carried over?

Workers can carry over up to 4 weeks of the 5.6 weeks statutory leave if they were unable to take it due to sickness, maternity/parental leave, or if the employer prevented them from taking it. The additional 1.6 weeks (or more if contractually given) may or may not carry over depending on the employment contract. From 1 January 2024, there are also provisions for irregular-hours workers to carry over accrued but unused leave.

Holiday Rights for Part-Time Workers in the UK

Part-time workers in the UK have the same rights to annual leave as full-time workers — the entitlement is simply calculated on a pro-rata basis. The statutory minimum under the Working Time Regulations 1998 is 5.6 weeks for all workers. For a full-time employee working 5 days per week, this works out as 28 days. A part-timer working 3 days per week receives 5.6 × 3 = 16.8 days — the same number of weeks, but fewer days because each working week is shorter.

The Part-Time Workers (Prevention of Less Favourable Treatment) Regulations 2000 make it unlawful for employers to give part-time workers a lower rate of holiday entitlement than comparable full-time workers without objective justification. This applies not only to the number of days but also to pay during holiday — a part-time worker must receive their normal rate of pay when taking annual leave, not a reduced rate.

Bank holidays require careful handling. Since bank holidays are included within the 5.6 weeks' statutory minimum, a worker who doesn't work Mondays can miss out disproportionately — most UK bank holidays fall on Mondays. Employers committed to fair treatment often give all part-time workers a pro-rata bank holiday allocation as part of their total annual leave, ensuring no one is disadvantaged by the days they happen to work.
