A new parental leave rule is now in force for mothers and fathers across the United Kingdom. The Labour Party government implemented changes to employment law in April, making paternity leave a 'day one right'.
Key Changes Effective from 6 April 2026
From 6 April 2026, employees are eligible for Paternity Leave and Unpaid Parental Leave from their very first day in a new job. Previously, workers needed 26 weeks of service for Paternity Leave and one year of service for Unpaid Parental Leave.
Both types of leave have become 'day one' rights. This means employees can now give notice from their first day of employment. Additionally, workers can now take Paternity Leave and Pay after Shared Parental Leave and Pay, which was not previously allowed.
Government Estimates and Benefits
Winckworth Sherwood LLP explained: "The reforms aim to widen access and give families greater flexibility in structuring leave following a child's birth or adoption." Government estimates suggest an additional 32,000 fathers or partners will be able to take paternity leave, and approximately 1.5 million working parents will gain access to parental leave.
"Although employers will face additional re-organisation costs (estimated at £24.7 million annually), the government anticipates benefits including reduced stress, improved workforce motivation, lower absence rates and improved retention." The measures form part of the wider 18-month review of parental leave and pay launched in July 2025.
Ministerial Statements
Employment Rights Minister Kate Dearden said: "No one should have to drag themselves into work when they're unwell because they can't afford not to — and no new parent should miss out on time with their child because they haven't been in their job long enough. These reforms put that right. This is what it means to make work pay for everyone."
Minister for Employment Dame Diana Johnson added: "No one should ever have to choose between their health and earning a living. For too long, sick employees have had to make the impossible decision between losing out on a day's pay or returning to work while ill. Today's landmark changes will support employees to recover while providing businesses with the peace of mind that their workforce can return to work healthier and more productive."
