Quickly see the key dates for paternity leave and the pay period you’ll need to work out Statutory Paternity Pay.
Our UK paternity leave calculator helps employers quickly work out the key dates for Statutory Paternity Leave and Statutory Paternity Pay. It’s updated for the Employment Rights Act changes from 6 April 2026, including the new day-one right to paternity leave.
To begin, simply enter the expected date of birth below.
As of 6 April 2026, Statutory Paternity Leave is a day-one right: any employee who meets the relationship/intent tests can take paternity leave, regardless of length of service. They can take up to 2 weeks, either as one 2-week block, or as two separate 1-week blocks, and at any time in the 52 weeks after birth.
Read on to understand:
Statutory Paternity Leave is time off work for an employee to care for their child or support their partner after birth or adoption.
As of 6 April 2026, paternity leave is a day-one right under the Employment Rights Act. That means employees no longer need a minimum length of service to take paternity leave.
Paternity leave sits alongside other family leave rights. It’s separate from, and in addition to:
Shared Parental Leave (SPL)
Unpaid Parental Leave
If you need to calculate maternity leave for an employee, try our maternity leave calculator. You'll also find more information about Statutory Maternity Leave and Statutory Maternity Pay here.
All eligible employees can take up to two weeks of paternity leave from day-one of employment. They can choose to take:
Paternity leave can be taken at any point within the 52 weeks after the child is born or placed for adoption. This replaces the previous 56-day limit.
Our paternity leave calculator shows the earliest and latest dates leave can be taken based on the expected due date. That makes it easier to plan rotas, cover and payroll.
While two weeks is the statutory minimum entitlement, some employers choose to offer enhanced paternity leave. This allows employees to take a longer period of leave than the statutory entitlement.
Statutory Paternity Pay (SPP) is the government-backed pay employers must provide during paternity leave.
As with Statutory Maternity Pay, most employers can reclaim the majority of the Statutory Paternity Pay they pay out from the HMRC, and small employers may be able to reclaim slightly more through Small Employers’ Relief.
For each week of SPP, the employee should receive the lower of:
This is the statutory minimum level of pay. Some employers choose to offer enhanced paternity pay, which provides a higher level of pay than the statutory entitlement.
While paternity leave is now a day-one right, employees still need to meet certain eligibility requirements to qualify for Statutory Paternity Pay.
To qualify for SPP, the employee must:
Our calculator gives you the latest date your employee needs to have joined the business to qualify for Statutory Paternity Pay and the 8-week pay reference period that you can use to calculate the employee’s average weekly earnings.
Employees must give notice when they plan to take paternity leave.
By the 15th week before the expected week of childbirth, they must:
For each week or block of leave they plan to take, they must:
Employers can also ask the employee to complete a declaration form confirming:
Use the notice deadline shown in the calculator to check whether entitlement notice has been given on time. You can then work out the 28-day notice deadlines for each planned leave week.
While an employee is on Statutory Paternity Leave, their employment rights are protected. This includes:
It’s unlawful to treat an employee unfavourably because they’ve taken or requested paternity leave.
Paternity leave is separate from maternity leave and Shared Parental Leave (SPL).
Shared Parental Leave is a statutory right in the UK that allows eligible parents to share up to 50 weeks of leave and up to 37 weeks of statutory pay following the birth or adoption of a child.
It works by allowing the mother or primary adopter to end their maternity or adoption leave early and convert the remaining entitlement into Shared Parental Leave. The parents can then divide that leave between them in a way that suits their family and work arrangements.
Employees can take paternity leave first, then move on to SPL later if they meet the eligibility rules.
A common approach is:
Historically, there were restrictions on when paternity leave could be taken if an employee also planned to take Shared Parental Leave.
But now employees can also:
This removes earlier limitations that tied paternity leave more closely to the first weeks after birth.
The result is more flexibility for families and employers, allowing parents to combine paternity leave and Shared Parental Leave in ways that suit their childcare plans.
Statutory Paternity Pay is paid during paternity leave, for up to two weeks.
If an employee later takes Shared Parental Leave, they may qualify for Statutory Shared Parental Pay. This is the same as the statutory family pay rate.
Shared parental pay can be paid for up to 37 weeks in total, shared between the parents. This pay usually comes from the unused portion of the mother’s or adopter’s statutory maternity or adoption pay entitlement.
How the two types of pay usually work together
In practice, an employee might:
Unpaid Parental Leave is a separate statutory right that allows employees to take unpaid time off to care for their child.
Eligible employees can take up to 18 weeks of Unpaid Parental Leave per child before the child turns 18 years old. This is a maximum of four weeks per child per year.
This type of leave is different from paternity leave or Shared Parental Leave. It is not tied to the birth or adoption period and can be used later as childcare needs arise.
As of 6 April 2026, Unpaid Parental Leave is also a day-one right, meaning employees no longer need one year of service to qualify.
Employees can take Unpaid Parental Leave in addition to paternity leave and Shared Parental Leave, as long as they meet the eligibility rules.
If a baby needs specialist neonatal care (for example intensive care in the first weeks after birth), parents may also be entitled to Neonatal Care Leave and Pay.
Employees can take Neonatal Care Leave from day-one of employment if their baby is admitted for neonatal care within 28 days of birth and stays in neonatal care for at least seven consecutive days.
Statutory Neonatal Care Pay is available to employees with at least 26 weeks’ service who earn at least £129 per week on average (the Lower Earnings Limit for 2026/27). It’s paid at £194.32 per week for the 2026 to 2027 tax year, or 90% of the employee’s average weekly earnings, whichever is lower.
Neonatal Care Leave and Pay are in addition maternity, paternity and Shared Parental Leave.
Employers should review their policies and processes.
Make sure your contracts, handbooks and policies reflect:

Key takeaways from employment law experts on the Employment Rights Act changes
Who qualifies for Statutory Paternity Leave and Statutory Paternity Pay?
To qualify for Statutory Paternity Leave, the individual must be an employee and must be:
They must also be taking the leave to care for the child or support the child’s mother or adopter.
As of 6 April 2026, paternity leave is a day-one right, meaning employees no longer need a minimum length of service to take the leave.
To qualify for Statutory Paternity Pay, additional conditions apply. The employee must:
Can paternity leave be taken in two separate weeks?
They can take:
If they take the leave in two blocks, each week must be taken as a full week, not individual days.
Employers must allow employees to choose how they take their paternity leave, as long as the correct notice requirements are met.
How long do employees have to take paternity leave after the baby is born?
Paternity leave can be taken at any point within the first 52 weeks after the child is born or placed for adoption.
This replaces the previous rule that required paternity leave to be taken within 56 days of the birth or placement.
The longer window gives employees more flexibility to choose when paternity leave will be most helpful for their family.
How does paternity leave interact with Shared Parental Leave?
Paternity leave and Shared Parental Leave are separate statutory rights.
Paternity leave provides a short period of leave (up to two weeks) around the time of the birth or adoption.
Shared Parental Leave allows eligible parents to share up to 50 weeks of leave and up to 37 weeks of statutory pay during the child’s first year.
In many cases, employees take paternity leave first, then take Shared Parental Leave later if the parents want to share childcare responsibilities.
Do zero-hours or part-time staff qualify for paternity leave?
Employees working part-time or on zero-hours contracts can qualify for paternity leave if they are legally classed as employees and meet the eligibility conditions.
For paternity leave itself, there is no minimum service requirement as of 6 April 2026.
But, eligibility for Statutory Paternity Pay still depends on:
This means some employees may qualify for paternity leave but not Statutory Paternity Pay.
Can employers offer enhanced paternity pay?
Yes. Employers can choose to offer enhanced paternity pay or enhanced paternity leave that goes beyond the statutory minimum.
For example, some employers offer:
Any enhanced policy must still meet the statutory minimum requirements for paternity leave and Statutory Paternity Pay.
Many employers include enhanced paternity benefits as part of a wider family-friendly policy to support working parents.
