Parental leave in the UK is 18 weeks of unpaid leave per child, available to eligible employees under the Employment Rights Act 1996, section 76. It is separate from maternity, paternity, and shared parental leave — designed as a block of flexible unpaid time off for parents to spend with a young child. Understanding the distinction matters: confusing it with Statutory Maternity Pay or Shared Parental Leave leads to missed entitlements and scheduling errors.

This guide covers UK parental leave in 2026: who qualifies, how many weeks you get, the notice you must give, what happens to your job, and how employers should manage it.

Key takeaways

  • Eligible employees can take 18 weeks of unpaid parental leave per child before the child turns 18, under section 76 of the Employment Rights Act 1996.
  • You need one year of continuous service to qualify — there is no length-of-service requirement beyond that.
  • Each week of leave is capped at one week’s pay, but the leave itself is unpaid. You cannot claim statutory pay for parental leave.
  • Notice must be given 21 days before the start of leave (or, for a child’s birthday, at least 21 days before the requested date).
  • Leave can be taken in blocks of one week or multiples of one week, up to the maximum of 18 weeks per child.
  • Your employment contract continues, and you have the right to return to the same role (or a suitable alternative if the role is no longer available).

Who qualifies for parental leave in the UK?

To be eligible, you must:

  • Be an employee (not a worker or self-employed)
  • Have 12 months of continuous service with your employer
  • Have or expect to have responsibility for a child under 18

There is no income threshold, no cap on hours worked, and no requirement that you are the biological parent. Adoptive parents, step-parents, and legal guardians all qualify. The child must be under 18 at the start of the leave.

Self-employed individuals and workers are not covered by the Employment Rights Act provisions, though some employers may offer enhanced policies voluntarily.

How many weeks of parental leave can you take?

The entitlement is 18 weeks per child, per parent. You cannot carry over unused leave to a later year — it must be used before the child turns 18.

Detail Rule
Maximum per child 18 weeks
Minimum block 1 week
Maximum blocks Up to 18 blocks of 1 week each
Child’s age limit Under 18 at the start of leave
Carryover Not permitted

You can spread the 18 weeks across the child’s lifetime, taking one week at a time or grouping weeks into a single block. This flexibility is useful for school transitions, medical appointments, or settling a child into a new care arrangement.

Worked example

A mother with two children aged 4 and 12 takes one week of parental leave for the older child’s school start and two weeks for the younger child’s nursery transition. She has used 3 weeks of her 18-week entitlement for each child.

Notice requirements

You must give your employer at least 21 days’ notice before the date you want the leave to start. For leave linked to a specific event — such as a child’s birthday — the notice must be given at least 21 days before that date.

The notice should include:

  • The date you want leave to start
  • The duration of the leave
  • The reason (parental leave for a child under 18)

You do not need to provide medical evidence or any documentation beyond the notice. Your employer can postpone the leave in limited circumstances (see below), but cannot refuse it outright.

Employer postponement rights

An employer can postpone parental leave if:

  • The employee has been employed for less than one year (not applicable — one year is a qualifying condition)
  • The business would be seriously disrupted if the leave were taken at the requested time
  • The employee is in a senior role or in a role where the employer has a genuine operational need

The postponement must be made in writing, within 7 days of receiving the notice. It can only be postponed by up to 6 months from the original start date. After that, the employee may take the leave at the revised date.

Employers should document the reason for postponement carefully — “business needs” alone may not withstand scrutiny if challenged at an employment tribunal.

What happens to your job during parental leave?

Your employment contract continues throughout the leave period. You continue to accrue:

  • Annual leave (statutory holiday entitlement)
  • Pension contributions (unless the contract specifies otherwise)
  • Length of service for employment law purposes

You have the right to return to the same role at the end of the leave. If your role has been made redundant or restructured while you were away, your employer must offer you a suitable alternative role at the same level.

Dismissal during or immediately after parental leave is automatically unfair under section 99 of the Employment Rights Act 1996, and you may bring an employment tribunal claim within three months.

Interaction with other parental leave types

Parental leave is one of several entitlements. Here is how it compares:

Leave type Duration Pay
Statutory Maternity Leave 52 weeks (39 weeks statutory pay) 90% of average weekly earnings (first 6 weeks), then flat rate
Statutory Paternity Leave 2 weeks Flat rate
Shared Parental Leave Up to 50 weeks shared Flat rate
Parental Leave (this article) 18 weeks per child Unpaid

You can combine parental leave with other types. For example, a mother may take Statutory Maternity Leave followed by 18 weeks of unpaid parental leave, giving up to 70 weeks total leave.

However, Shared Parental Leave and parental leave have different rules and cannot run simultaneously. You must finish one before starting the other.

Employer obligations

Employers managing parental leave should:

  1. Maintain a clear policy that explains the entitlement, notice process, and postponement criteria
  2. Record parental leave separately from other absence types
  3. Respond to postponement requests in writing within 7 days
  4. Protect the employee’s role or offer a suitable alternative
  5. Keep employment terms active during the leave period
  6. Avoid dismissal or selection for redundancy during or immediately after parental leave without careful legal review

Common pitfalls

1. Confusing parental leave with paternity leave

Paternity leave is 2 weeks of leave at statutory pay for fathers and partners. Parental leave is 18 weeks of unpaid leave for any qualifying parent. They are separate entitlements with different notice and pay rules.

2. Forgetting to extend the leave before the child turns 18

Unused parental leave cannot be carried over. If a child turns 18 while you still have entitlement, the remaining weeks are lost.

3. Refusing parental leave based on business needs

An employer can postpone parental leave but cannot refuse it. Forcing an employee to take annual leave instead of parental leave is not lawful.

4. Not updating employee records

Failing to record the leave period creates problems when calculating redundancy, redundancy selection, or promotion eligibility. The leave counts as continuous service.

Putting it into practice

Three checks cover most UK parental leave scenarios:

  1. Build parental leave into your policy library so employees know about it before they need it — it is a common gap in handbooks that assume employees only use maternity or paternity leave.
  2. Track parental leave separately from annual leave and sick leave, so reporting on absence is accurate and employees are not penalised for taking an entitlement.
  3. Set a reminder when an employee’s child approaches 18 to check whether any entitlement remains.
You can take advantage of the free 14 days trial and explore Leave Balance.

Tracking 18 weeks of unpaid leave across multiple children and notice windows is straightforward with a system that holds parental leave as a distinct absence type, calculates entitlement per child, and alerts you when postponement decisions are needed.
