Parental leave is the right for employed parents to take unpaid time off work to look after their child’s welfare. In the UK, eligible employees can take up to 18 weeks of unpaid parental leave per child until that child turns 18. It sits alongside maternity, paternity and adoption leave as a distinct legal entitlement.
When you are a new parent, or you’re about to have a child, you become entitled to certain rights. This one is among the most useful yet least understood. This guide explains who qualifies, how much you can take, and how to claim it correctly under current UK rules.
What is parental leave?
Parental leave is statutory unpaid time off that lets employed mothers and fathers step away from work to fulfil parenting duties. Unlike maternity or paternity leave, it is not tied to the period immediately after birth. Instead, it can be used flexibly across childhood.

Why take time off for your child?
At certain stages of parenthood, you may need more time than usual to look after your child. This right allows you to stop working for a while in order to meet those responsibilities. Parents use the time off for many reasons.
For instance, you might want to settle a child into a new school or visit family who live far away. It can also help with unexpected problems, such as a breakdown in childminding arrangements. By contrast, it is not designed for routine holidays.
Who is eligible for parental leave?
To qualify, you must have worked as an employee for the same company for at least one year. You must also be named on the child’s birth or adoption certificate, or otherwise have parental responsibility. If you do not automatically have it, you can apply for parental responsibility as the father, the second female parent, or the step-parent.
However, you are not entitled to this unpaid time off if you are self-employed, a contractor, or an agency worker. Foster parents are also ineligible in most cases. Nevertheless, depending on your staff handbook, your employer may choose to extend the right to you anyway. It is always worth checking, as some workplaces are more generous than the legal minimum. These rules apply equally to gay and lesbian parents and to co-parents raising a child together.
How much parental leave can I take?
Parents are entitled to 18 weeks of unpaid leave for each child. You can use this right just after the birth or adoption, after maternity or paternity leave, or at any point until your child is 18.
You must take it in blocks of a week or several weeks. In addition, you cannot exceed four weeks a year per child unless your employer agrees otherwise. Exceptions apply for parents of disabled children, who have more flexibility. The weeks you take must match your average working week, so one week equals four days if you work a four-day week.
How do I claim it?
If you decide to use your right to unpaid time off, you must give notice no later than 21 days before the leave is due to start. Some employers require written notice, so it is always best to check first. You remain employed throughout your absence, and your continuity of service is protected.
Your employer may ask you to prove your parental situation, for example by providing a copy of your child’s birth certificate. However, they cannot demand proof every single time you ask. Equally, your employer cannot refuse a valid request as long as you are eligible and follow the correct procedure, though they may postpone it for up to six months if the timing would seriously disrupt the business.
What about shared parental leave?
Statutory parental leave should not be confused with shared parental leave, a separate entitlement introduced in 2015. The official Acas guidance on shared parental leave explains that its purpose is to let mothers, fathers, adopters and partners share time off during the first year after birth or adoption.
This right applies to co-habiting parents and same-sex couples, as well as couples raising a child together, regardless of whether the child comes from a previous relationship. For families navigating co-parenting and donor conception arrangements, understanding how these rights interact is particularly important.
Frequently asked questions
How many weeks of parental leave am I entitled to in the UK?
You are entitled to 18 weeks per child, capped at four weeks per child per year unless your employer agrees to more. You can use it any time until the child turns 18.
Is it paid?
No. This statutory time off in the UK is unpaid. Some employers offer enhanced contractual schemes with pay, so check your staff handbook or employment contract for any additional benefits.
Can my employer refuse my request?
Your employer cannot refuse a valid request if you are eligible and give 21 days’ notice. They can, however, postpone it by up to six months if your absence would cause serious disruption, except where it is taken straight after birth or adoption.
Who is not eligible?
Self-employed people, contractors, and agency workers do not qualify. Foster parents are usually excluded too, although individual employers may extend the right voluntarily through their own policies.

Statutory leave is 18 weeks of unpaid time off per child usable until age 18. Shared parental leave is a separate scheme letting partners share leave and pay during the first year after a child arrives.
