As we approach the end of the year, many UK SMEs begin reviewing staff leave balances, and that’s often when holiday management becomes a real challenge. One of the most common questions businesses face is whether employees can “carry over” holiday into the next leave year and under what circumstances.
This blog breaks down the rules, the risks and what employers need to know to stay compliant and avoid confusion.
What is “carry over” of holiday?
“Carry over” means allowing an employee to use unused holiday entitlement from one leave year in the next. For example, if your organisation’s leave year runs from 1st January to 31st December and a worker hasn’t taken all their holiday by 31st December, you’ll need to decide whether some of that holiday can be used after 1st January.
It is not automatically allowed by law in all situations. Whether holiday can be carried over depends on the type of entitlement, the reason it wasn’t taken and what your employment contracts or policies state.
The legal minimum entitlement and the “use it or lose it” rule
Under UK law, full-time workers are entitled to 5.6 weeks’ paid holiday per year (28 days for a five-day week, including bank holidays, unless the contract says otherwise).
The core 4 weeks of this entitlement (from EU law) cannot ordinarily be carried over simply because a worker didn’t use it in time. This is where the familiar “use it or lose it” rule comes from.
However, exceptions apply in certain circumstances, which we cover below.
When can holiday be carried over?
A) Where an agreement allows it
Carry over is permitted if your employment contracts, employee handbook or any collective/workforce agreements specify that unused leave can be moved into the next leave year.
B) For contractual holiday beyond the legal minimum
If your business offers more than 5.6 weeks of holiday, you decide, via your policy, whether the additional days can be carried over.
C) When statutory leave prevents holiday being taken
Employees can carry over holiday if they were unable to take it due to maternity, paternity, adoption, shared parental leave or long-term sickness.
D) If the employer prevented the employee from taking leave
If you did not encourage or allow an employee to take their statutory holiday, or failed to inform them that unused leave would be lost, they may have the right to carry over up to four weeks.
What this means for UK SMEs
For SMEs, clarity is crucial. Ensure your contracts and holiday policy clearly explain whether carry over is allowed and how it works. Encourage staff to take leave steadily throughout the year and monitor remaining balances as the end of the leave year approaches.
If you allow carry over, especially for contractual holiday, keep the rules simple and easy to understand. Remember that statutory exceptions such as maternity leave, adoption leave and long-term sickness must be honoured. Finally, make sure managers, payroll and HR systems are aligned so holiday records remain accurate and compliant.
Frequently asked questions
Q: Can I force an employee to carry over leave?
You can enforce a “use it or lose it” policy for statutory holiday, but only if you have clearly encouraged the employee to take their leave and warned them that it will be lost if not used. If not, you may have to allow carry over.
Q: Can an employee carry over all their holiday?
Not usually. The core 4 weeks cannot normally be carried over unless specific exceptions apply. Contractual holiday above the 5.6-week minimum can be carried over if your policy permits.
Q: What happens if an employee is off sick all year?
They can carry over up to 4 weeks and must use it within 18 months of the end of the leave year in which it was accrued.
Q: Can I change my holiday policy mid-year?
Yes, but not retrospectively for statutory entitlement already accrued. Any changes must still comply with employment law and be clearly communicated to staff.
