U.K. Maternity Leave: How Does It Work?

Maternity leave isn’t just a workplace benefit—it’s a critical support system. Research across multiple countries shows that paid maternity leave can significantly improve an individual’s physical and mental health outcomes.

Offering employees this support is both an ethical responsibility and a legal requirement. Like many other countries, the U.K. requires that employees receive appropriate time away from work when they welcome a child.

But managing maternity leave in the U.K. is more complex than just granting a few weeks off. It exists within a detailed legal framework that outlines specific entitlements, statutory pay, and employer obligations. For global companies, the process becomes even more challenging, as maternity leave rules vary widely from one country to another.

This guide breaks down how U.K. maternity leave policy works. If you’ve ever wondered how long maternity leave lasts in the U.K. or what your responsibilities are as an employer, this is the place to start.

How does maternity leave work in the U.K.?

Eligible employees in the U.K. can take up to 52 weeks of Statutory Maternity Leave. This includes 26 weeks of Ordinary Maternity Leave followed by 26 weeks of Additional Maternity Leave.

Maternity leave is a legal entitlement under U.K. employment law. While employees can choose to take less than the full year, they must take at least two weeks of compulsory leave after birth (or four weeks for factory workers) for health and safety purposes.

Statutory Maternity Leave may begin up to 11 weeks before the due date and comes with strict job protections:

• After Ordinary Maternity Leave. The worker is entitled to return to the same job with the same employee benefits and conditions of employment.
• After Additional Maternity Leave. The worker is entitled to return to the same job or a suitable alternative with similar benefits and pay.

How much is maternity pay in the U.K.?

Although all eligible employees are entitled to time off under U.K. maternity leave policy, not everyone qualifies for paid leave. Statutory Maternity Pay (SMP) is the mandatory compensation employers must provide to eligible workers for up to 39 weeks of their maternity leave.

While paid maternity leave is common around the world, the specific rules vary by country. Here’s an overview of how maternity pay works in the U.K. so global employers understand their obligations.

Who qualifies for Statutory Maternity Pay?

Maternity leave and maternity pay aren’t the same thing—not everyone eligible for maternity leave qualifies for maternity pay. SMP has its own eligibility requirements, and employees must meet all of them to receive paid leave. To qualify, an employee must:

• Earn at least £129 per week on average
• Provide notice and proof of pregnancy at least 15 weeks prior to the due date
• Have maintained continuous employment with the company for a minimum of 26 weeks by the “qualifying week” (15th week before the expected week of childbirth)

If an employee doesn’t meet these criteria, they may still qualify for a government-funded maternity allowance for up to 39 weeks.

How does Statutory Maternity Pay work?

Once an employee submits their notice of pregnancy, employers must respond within 28 days and confirm the maternity leave start and end dates.

And maternity pay isn’t discretionary. To stay compliant with U.K. employment regulations, you need to follow a structured SMP process: Determine whether the employee is eligible for maternity pay, calculate the correct payment, and administer it through your existing payroll system.

Under SMP rules, eligible employees receive:

• For the first six weeks. A minimum of 90% of their average weekly earnings before tax
• For the next 33 weeks. 90% of their average weekly earnings or £187.18 per week, whichever is lower

What is enhanced maternity pay?

Some companies choose to offer compensation beyond SMP. In these cases, employers can design their own enhanced maternity packages. For example, some companies provide 6–12 weeks of full pay (instead of the required 90%), then transition to the standard SMP for the rest of the leave duration.

U.K. employment law sets the floor, not the ceiling. As long as you meet the minimum requirements, you’re free to create internal policies that offer enhanced maternity benefits.

Employer responsibilities during maternity leave

Regardless of where your organization is headquartered, if you employ people in the U.K., you must adhere to all U.K. maternity leave policies. This means meeting your legal obligations as an employer before, during, and after an employee’s leave.

Protect employee rights

Pregnancy and maternity leave come with strong legal protections in the U.K. Employees can’t be treated unfairly, discriminated against, or have their contract altered or terminated because they’re expecting a child.

After Ordinary Maternity Leave, employees must be allowed to return to the same role under the same terms and conditions. If they choose to take Additional Maternity Leave and their original role is no longer practical, you’re still required to offer a suitable alternative role with similar pay, terms, and benefits upon their return.

Manage payroll and statutory payments

During maternity leave, payroll doesn’t pause. You must determine the employee’s SMP eligibility, calculate the correct compensation, and administer payments consistently through your usual payroll schedule. You must continue to follow U.K. payroll tax and reporting requirements through the leave period just as you would if the employee were working.

SMP payments are mandatory for eligible employees for up to 39 weeks, and are enforced by HM Revenue and Customs (HMRC), the authority responsible for tax and payroll oversight in the U.K.

Maintain employment benefits

Workers retain all their employee rights throughout the full maternity leave period, which means you must continue providing benefits and non-cash compensation during their time away. For example, workers continue to accrue holiday leave and remain entitled to all contractual benefits, such as pension contributions or private medical insurance.

Handle leave notifications and documentation

Employees are required to notify you of their pregnancy at least 15 weeks before the due date. Their notice should outline the planned leave dates and include a MAT B1 form from a GP or registered midwife as proof of pregnancy.

Your job is to document everything. Confirm leave approvals in writing and keep clear records of pay calculations, notice, enhanced benefits, and related correspondence. Proper recordkeeping helps you stay compliant with HMRC regulations and provides evidence for reimbursement.

Broader U.K. compliance considerations for international employers

Maternity leave is just one part of the U.K.’s compliance landscape. If you’re a global employer based outside the U.K., managing the country’s wider regulatory framework can quickly become challenging.

Here are some key considerations for multinational companies hiring in the U.K.:

• Hiring without a U.K. legal entity. Establishing a legal entity in the U.K. as a foreign company can be expensive and time-consuming. For this reason, many global companies rely on an Employer of Record (EOR) to legally hire and manage U.K. employees on their behalf. EORs often have structured compliance systems that help companies operate across borders without a separate entity.
• Coordinating payroll, PAYE, and National Insurance contributions. HMRC enforces strict rules for employee compensation and payroll administration. The U.K. operates under a pay-as-you-earn (PAYE) system, which means employers are required to withhold income tax and National Insurance contributions from employee wages. As an employer, you must register for PAYE and follow all payroll and tax reporting requirements to remain compliant.
• Keeping up with changing U.K. employment law. Employment law and employer obligations evolve continuously with new legislation and legal clarifications. Both domestic and foreign employers need to keep a close eye on changes and update their internal policies to reflect current requirements.
