Why this matters.
The Employment Rights Act 2025 removed the qualifying service requirements for paternity leave and unpaid parental leave, making both available from the first day of employment. Previously, employees needed 26 weeks’ service for paternity leave and a year for parental leave. Employers who still apply those old thresholds in handbooks, HR systems or manager guidance risk unlawfully refusing leave, which can lead to detriment and automatic unfair dismissal claims under the Employment Rights Act 1996 and the Paternity and Adoption Leave Regulations 2002.
Beyond eligibility, employers need to handle notice, evidence and pay correctly. Statutory Paternity Pay still has its own earnings and notice rules, and employees can take leave in separate blocks within the first 52 weeks. Employers must also avoid treating employees less favourably for taking or asking about leave, and keep records that show decisions were consistent. A short policy and process review now is far cheaper than a tribunal claim later.
