Unpaid Leave UK: Employer Guide to Rules & Policies

Unpaid leave is one of those areas of employment law where there is often a gap between what employees expect and what they are actually entitled to. There is no general legal right to take unpaid leave in the UK — but there are several specific statutory rights, and most employers also offer discretionary unpaid leave in certain circumstances. This guide explains the rules, the statutory entitlements, and how to create a clear policy.

Is there a right to unpaid leave in the UK?

No. There is no general right to take unpaid leave from work in the UK. An employee cannot simply decide to take time off without pay and expect the employer to agree. However, there are several specific statutory rights to unpaid time off, and employers may also grant unpaid leave on a discretionary basis.

The distinction matters because an employer can refuse a general request for unpaid leave (it is entirely at their discretion), but they cannot refuse statutory unpaid leave where the employee meets the qualifying criteria.

Statutory unpaid leave: time off for dependants

Under Section 57A of the Employment Rights Act 1996, all employees have a day-one right to take a "reasonable" amount of unpaid time off to deal with an emergency involving a dependant. There is no qualifying period.

A dependant includes a spouse, civil partner, child, parent, or anyone who lives in the same household (other than a lodger or tenant). It can also include someone who reasonably relies on the employee for care.

What counts as an emergency?

A dependant falls ill, is injured, or is assaulted.
A dependant gives birth (this is about being present for the emergency, not about paternity leave).
Arrangements for the care of a dependant break down unexpectedly — for example, a childminder cancels at short notice.
An incident involving the employee's child at school.
A dependant dies (though many employers offer paid compassionate leave for bereavements).

The right is to deal with the immediate emergency, not to provide ongoing care. Typically this means one or two days — enough to arrange alternative care or deal with the crisis. There is no set maximum, but the time off must be "reasonable" in the circumstances.

The employee must tell the employer as soon as reasonably practicable why they are absent and how long they expect to be away. Refusing this statutory right or subjecting an employee to a detriment for taking it is unlawful.

Statutory unpaid leave: parental leave

Employees with at least one year's continuous service are entitled to 18 weeks of unpaid parental leave per child, which can be taken up until the child's 18th birthday. This is a separate entitlement from maternity, paternity, or shared parental leave.

The default rules (which apply unless there is a collective or workforce agreement in place) are:

A maximum of 4 weeks per child per year.
Leave must be taken in blocks of one week (unless the child is disabled, in which case single days are permitted).
The employee must give 21 days' notice.
The employer can postpone the leave for up to 6 months if it would cause significant disruption to the business — but they cannot refuse it outright (except in the case of postponement, and they cannot postpone leave requested immediately after the birth or adoption of a child).

The 18-week entitlement is per child, not per employer. If an employee has already taken 10 weeks of parental leave with a previous employer, they have 8 weeks remaining with their current employer.

Statutory unpaid leave: time off for public duties

Employees who hold certain public positions are entitled to a reasonable amount of unpaid time off to carry out those duties. The employer does not have to pay them, but must allow the time off. Qualifying positions include:

Magistrate (Justice of the Peace).
Local councillor.
Member of a statutory tribunal (e.g., employment tribunal).
Governor of a school or further education institution.
Member of a health authority, NHS trust, or other public body.
Trade union representative (for duties and training).

What counts as "reasonable" depends on how much time is needed, how much the employee has already taken, and the impact on the employer's business. There is no set number of days — it is assessed case by case.

Discretionary unpaid leave

Beyond the statutory entitlements above, any other unpaid leave is entirely at the employer's discretion. Common scenarios where employers may grant discretionary unpaid leave include:

Extended travel or sabbaticals — an employee wants to travel for several weeks or months.
Study or training — time off for courses or qualifications not directly related to the job.
Personal reasons — moving house, dealing with family situations, or pursuing personal projects.
Religious observance — time off for religious holidays not covered by annual leave (note: employers should consider indirect discrimination if they routinely refuse).
Exhausted annual leave — the employee has used all their paid holiday and requests additional time off.

There is no legal obligation to say yes. However, employers should be consistent and fair in how they handle requests to avoid claims of discrimination or unfair treatment.

Impact on benefits, pension, and continuity

Taking unpaid leave has several practical consequences that both employers and employees should understand:

Continuity of employment — statutory unpaid leave (parental leave, time off for dependants) does not break continuity of employment. Discretionary unpaid leave also typically does not break continuity, provided the employment contract remains in force.
Annual leave accrual — during statutory parental leave, the employee continues to accrue annual leave. During discretionary unpaid leave, accrual depends on the terms of the agreement — many employers stop accrual during extended unpaid absence.
Pension contributions — no pay means no employer or employee pension contributions during the unpaid period (unless the contract states otherwise).
Benefits — company benefits such as private healthcare or life insurance may continue depending on the policy terms. Check with your provider.
National Insurance — no NI contributions are due during periods of nil pay, which could create gaps in the employee's NI record if the unpaid leave is extended.

Creating an unpaid leave policy

Having a clear unpaid leave policy avoids confusion and ensures consistent treatment. A good policy should cover:

Scope: who can apply, and in what circumstances unpaid leave may be considered.
Notice period: how much notice the employee must give (e.g., at least 2 weeks for discretionary requests).
Maximum duration: any limits on how long unpaid leave can last.
Approval process: who approves requests (line manager, HR, or both).
Impact on pay and benefits: what happens to salary, pension, holiday accrual, and other benefits during the absence.
Return to work: any expectations about confirming the return date and the role available on return.
Statutory rights: a clear statement that statutory unpaid leave (parental leave, time off for dependants) is separate and governed by law.

How Leavely tracks unpaid leave

Tracking unpaid leave manually can quickly become messy — especially when you need to distinguish between statutory and discretionary unpaid leave, manage accrual implications, and maintain accurate records for payroll. Leavely handles it all:

Separate leave types — configure unpaid parental leave, time off for dependants, and discretionary unpaid leave as distinct leave categories, each with their own rules.
Request and approval workflow — employees submit unpaid leave requests through Leavely, and managers approve or decline with a clear audit trail.
Accrual control — choose whether annual leave continues to accrue during each type of unpaid leave.
Calendar integration — unpaid leave appears on the team calendar alongside all other absence types, so coverage gaps are immediately visible.
Payroll reporting — generate reports showing unpaid leave periods for payroll processing, ensuring deductions are accurate.
