Employment rights update

Parental leave: the new day-one right from October 2026

Updated 18 October 2026

From 6 October 2026, parental leave is a day-one right in Great Britain. Anyone with a child under 18 can ask for unpaid time off, and the old one-year qualifying period no longer applies. Here is what actually changes, who it covers, and how to use the new rules in practice.

What is changing about parental leave in October 2026

Parental leave is the right to take unpaid time off to look after a child under 18. Until October 2026, an employee had to have at least one year of continuous service with their current employer before they could use it. Under the Employment Rights (Amendment, Revocation and Transitional Provision) Regulations 2026, that one-year service test is removed, and the right becomes available from day one of employment.

The headline numbers stay the same: 18 weeks of unpaid leave per child, capped at 4 weeks in any one year, and only one parent can take the leave at a time unless the employer agrees otherwise. What is changing is the eligibility, the way leave can be taken in smaller chunks, and the notice and evidence rules.

The reform sits inside the wider package of family-friendly rights being rolled out across October 2026, which also covers neonatal care leave, paternity leave, and protection from dismissal for taking family leave. Read it as a single, deliberate shift towards earlier, broader access to time off for parents and carers.

Who can now ask for parental leave

You qualify if you are an employee, have a child under 18, and either:

• have, or expect to have, formal parental responsibility for the child, or
• are named on the child's adoption or parental order, or
• are the partner of the child's mother or adopter, including same-sex partners.

You no longer need to have worked for your employer for 12 months, and you no longer need to have a minimum number of hours per week. Agency workers, fixed-term employees, and zero-hours workers are all in scope from their first assignment, provided the assignment is not genuinely casual and there is a contract of employment.

If you are a freelancer on a self-employed basis, the right does not apply to you directly, but if you have a contract of employment alongside the freelance work, that contract will count.

How to take parental leave under the new rules

The leave can be taken in blocks, or, where the employer agrees, in individual days or half-days. Under the October 2026 changes, an employee can split the 18 weeks into up to three blocks per child per year, and the employer can only refuse if the leave would unduly disrupt the business. The old rule that required the leave to be taken in single weeks is being relaxed.

You must give your employer notice, in writing, of the dates you want to take off. The standard notice is at least four weeks before the start of each block, although shorter notice can be agreed. You do not have to give a reason beyond saying that you want to take parental leave. The employer can ask to see evidence of your responsibility for the child, such as a birth certificate, adoption certificate, or child arrangement order, but only where it is reasonable to do so.

If your employer refuses, they must do so in writing within seven days, and they must give the business reason. You can challenge a refusal through your employer's grievance procedure and, if needed, at an employment tribunal.

Pay, pensions and what your employer cannot do

Parental leave is unpaid. There is no statutory entitlement to pay while you are off, although your contract may offer enhanced terms, and some employers choose to top up at their discretion. If you are off on parental leave for the whole or part of a week, your period of continuous service continues as normal, and any accrued annual leave should be calculated on full pay as if you had been at work.

From October 2026, the regulations clarify that employer pension contributions should continue during parental leave on the same basis as during other forms of family leave, mirroring the position already in place for maternity and adoption leave. If you contribute to a workplace pension, your employer should keep paying their share while you are on parental leave, and you should not see a gap in contributions.

It is automatically unfair to dismiss an employee for taking, or seeking to take, parental leave. If you are dismissed for this reason, you do not need a qualifying period of service to bring a claim, and there is no upper limit on the compensation an employment tribunal can award.

Parental leave vs other family-friendly rights

Parental leave sits alongside, and does not replace, other family-friendly rights that are also being updated in October 2026:

• Maternity leave - up to 52 weeks of statutory maternity leave, with the first 26 weeks as ordinary maternity leave and the next 26 as additional maternity leave. Pay is separately governed by statutory maternity pay or maternity allowance.
• Paternity leave - the new framework extends the window in which paternity leave can be taken and removes some of the notice restrictions.
• Adoption leave - mirrors maternity leave in length and structure, with the same day-one protection from dismissal.
• Shared parental leave - up to 50 weeks can be shared between parents, subject to eligibility and notice rules.
• Neonatal care leave - a separate entitlement for parents of babies who spend 7 or more continuous days in neonatal care, now in force from 6 October 2026.
• Time off for dependants - the existing right to a short period of unpaid time off to deal with an emergency involving a dependant.

These rights can stack. You can, for example, use shared parental leave for the first year after birth, then take parental leave in blocks until the child is 18. The total time you can take is generous on paper, but the practical question is usually whether you can afford to be unpaid, and how the leave fits with your partner's arrangements.

Common questions about the new rules

Can my employer say no to the dates I want? Only if the leave would unduly disrupt the business, and the refusal must be in writing within seven days with the business reason given. The employer can propose alternative dates but cannot refuse outright without justification.

Do I have to take the leave in full weeks? Not any more. Under the October 2026 reforms, leave can be taken in blocks of one week or longer, or in individual days or half-days if your employer agrees.

Can I take parental leave for a stepchild or adopted child? Yes, as long as you have formal parental responsibility or are named on the adoption order.

What if I am on a zero-hours or fixed-term contract? The day-one right applies, but only if you have a contract of employment. Genuinely casual work on a self-employed basis is not covered.

Does parental leave count towards redundancy protection? Time on parental leave counts as continuous service and is protected in the same way as time spent on other forms of family leave.

What to do in the meantime

If you want to take parental leave after 6 October 2026, write to your employer as soon as you can, giving at least four weeks' notice of the dates you want. Keep a copy of the letter, and ask for the response in writing. If your employer refuses, ask for the written business reason and the alternative dates they are offering, and treat the refusal as a starting point for a grievance rather than a final answer.

If you have already had a request for parental leave turned down because you had not completed one year of service, that request is no longer valid as a refusal. You can re-submit it under the new rules from 6 October 2026, and the new notice and block rules will apply.
