Day-One Paternity, Parental and Bereaved Partner's Leave: A 2026 Guide

Maternity leave has long been a day-one right in the UK, available from an employee's first day of employment regardless of length of service. Paternity leave and unpaid parental leave have not had the same status — both have historically required a minimum period of continuous service before an employee could take them. From 6 April 2026, that gap closes: paternity leave and unpaid parental leave become day-one rights, and a new statutory entitlement to bereaved partner's leave is introduced for the first time.

This guide sets out what's changing across all three entitlements and what employers need to update in policy and payroll before the changes take effect.

Paternity leave as a day-one right

Currently, an employee typically needs a minimum period of continuous service with their employer before qualifying for statutory paternity leave, which excludes employees who change jobs shortly before or during a partner's pregnancy. From 6 April 2026, that service requirement is removed, meaning eligible fathers and partners can take statutory paternity leave from their very first day in a new role, matching the day-one entitlement that has long applied to maternity leave.

This is a meaningful change for employees who move jobs during a pregnancy or shortly after a birth or adoption, and it means employers can no longer rely on a new starter's short length of service as a reason to decline a paternity leave request in principle — the eligibility test shifts to the other statutory conditions (such as relationship to the child and expected responsibility for the child's upbringing) rather than tenure.

Unpaid parental leave as a day-one right

Unpaid parental leave — which allows eligible parents to take up to 18 weeks of unpaid leave per child up to their 18th birthday, subject to notice requirements — has also historically required a minimum service period before it could be taken. That requirement is removed from the same date, meaning new starters gain access to unpaid parental leave immediately rather than having to wait to accrue qualifying service.

Because parental leave is unpaid, this change is less about direct cost to employers and more about workforce planning: HR and line managers need to be ready to process parental leave requests from staff regardless of how recently they joined, and update any internal guidance or forms that currently reference a minimum service requirement that no longer applies.

A new right: bereaved partner's leave

The most novel change is a new statutory entitlement for bereaved partners. Where a mother or primary adopter dies within a defined period after the birth or adoption of a child — up to one year — the surviving partner becomes entitled to leave to care for the child, with an entitlement running up to 52 weeks in these circumstances. This closes a genuine gap in the existing leave framework, which previously had no dedicated statutory provision addressing this situation, leaving bereaved partners reliant on employer discretion or general compassionate leave policies that vary widely between employers.

Employers should treat this as a distinct entitlement requiring its own policy language, rather than assuming existing bereavement or compassionate leave provisions already cover it adequately — the statutory right is specific in its trigger (death of the mother or primary adopter within the specified period) and its duration, and employees should not need to negotiate an ad hoc arrangement to access it.

What employers need to update

• Staff handbooks and family leave policies. Remove references to minimum service requirements for paternity and parental leave, and add a clear section explaining the new bereaved partner's leave entitlement, including how employees or their representatives should notify the employer.
• HR systems and eligibility checks. Any automated eligibility check in an HR or payroll system that filters paternity or parental leave requests by length of service needs to be updated so it does not incorrectly decline day-one requests.
• Manager training. Line managers who handle leave requests directly should understand that service length is no longer a valid reason to question paternity or parental leave eligibility, and should be briefed sensitively on how to handle a bereaved partner's leave request given the circumstances involved.
• Coordination with existing family leave guidance. These changes sit alongside the broader entitlements covered in our guide to flexible working, family leave and carer rights, and policies should be updated together rather than in isolation so staff see one consistent picture of family leave rights.

Frequently asked questions

When do these changes take effect?

All three changes — day-one paternity leave, day-one unpaid parental leave, and the new bereaved partner's leave entitlement — take effect from 6 April 2026, alongside other Employment Rights Act 2025 reforms.

Does removing the service requirement change how much paternity pay is paid?

No — this change affects eligibility to take the leave itself from day one, not the statutory rate of paternity pay, which continues to be governed by separate rules including its own qualifying conditions.

Is bereaved partner's leave paid or unpaid?

The entitlement is to leave of up to 52 weeks in the specified circumstances; employers should confirm the applicable pay arrangements as part of implementing the new right, since this is a novel entitlement without extensive precedent in existing employer policies.

These changes close real gaps for employees who move jobs around the time of a birth or adoption, and for the rare but devastating situation where a partner dies shortly after becoming a parent. Updating policy language and system eligibility checks before 6 April 2026 avoids both compliance risk and the difficulty of telling a new starter or a grieving employee that a policy update simply hasn't caught up yet.
