Neonatal Care Leave calculator

A right that did not exist until 2025

Before April 2025, a parent whose baby went into neonatal care had exactly the same leave as a parent whose baby came home in two days. Maternity leave started ticking on the day of the birth whether or not the baby was in the building, and families routinely arrived home after eight weeks in a neonatal unit with eight weeks of their leave already spent sitting beside an incubator.

Neonatal Care Leave and Statutory Neonatal Care Pay fixed that, for babies born on or after 6 April 2025. It is a new day-one right for employees, and it is unusual among statutory entitlements in one specific way: it is added to what you already had rather than taken out of it.

One week for every seven days

The arithmetic is deliberately simple. Every seven full and continuous days your baby spends in neonatal care earns one week of leave, up to a ceiling of twelve weeks. A fortnight in the unit earns two weeks; a three-month stay earns the full twelve.

Part-weeks do not round up, which is worth knowing if a discharge date is being discussed around a seventh day. Twenty days earns two weeks, not three. Twenty-one earns three.

The definition of neonatal care is wider than most people assume. It covers care that starts in the first 28 days after birth, and that includes not just hospital care but consultant-led medical care after discharge where the hospital has arranged ongoing visits or checks. If your baby came home on oxygen with hospital-arranged reviews, ask whether that counts before assuming it does not.

It sits on top, not inside

This is the part worth saying loudly, because it is the difference between the new right and the old situation. If your baby goes into neonatal care while you are on Statutory Maternity Leave, you do not lose those weeks. The Neonatal Care Leave is added to the end of your maternity leave rather than swallowed by it.

GOV.UK gives the worked example directly: a baby who spends 56 days in neonatal care generates 8 weeks of Neonatal Care Leave, and instead of losing 56 days of maternity leave, the parent adds those 8 weeks to the end of the 39 weeks. The same principle applies to adoption leave.

Shared Parental Leave and Statutory Paternity Leave interact slightly differently: Neonatal Care Leave can be taken before those start, or between blocks of Shared Parental Leave booked before the baby went into care. Once you are more than a week past discharge, all remaining neonatal leave has to be taken in one continuous block.

Two tiers of notice, and the first is designed for a hospital corridor

The notice rules recognise that a parent standing in a neonatal unit cannot give 28 days' written notice of anything. While your baby is in care, or in the week after they leave — described in the guidance as "tier 1" — you tell your employer on the day the leave starts, ideally before your usual start time or as soon as you can afterwards. Phone, voicemail or text is fine. It does not have to be in writing.

If the stay continues, you tell them again by the end of each week. Employers can agree to less frequent contact if the stay is likely to be long, and it is a reasonable thing to ask for.

Take the leave more than a week after discharge and it hardens into "tier 2": 15 days' notice for a single week, 28 days for two or more, in writing, and taken in one continuous block. Notice for the pay itself can be given up to 28 days after the leave starts, and that part does have to be in writing.

Where families fall through

The commonest gap is between leave and pay. Neonatal Care Leave is a day-one right — it does not matter how long you have worked for your employer. Statutory Neonatal Care Pay requires 26 weeks of continuous employment up to the end of the qualifying week, and average weekly earnings at or above the lower earnings limit. Somebody who started a job two months before the birth may have twelve weeks of leave available and no pay attached to any of it.

The qualifying week itself shifts depending on what else you are claiming. If you are getting maternity or paternity pay it is the fifteenth week before the due date. If you are getting adoption pay it is the week you were matched. Otherwise it is the week immediately before the baby entered neonatal care.

The other gap is geography and employment status. The leave applies to employees in England, Scotland and Wales. Agency workers, workers who are not employees, and the self-employed are not covered by the leave right, though some may still have contractual or discretionary options worth asking about.

Twins, multiples and the twelve-week ceiling

If two babies are in neonatal care at the same time, you can only claim for one of them, still capped at twelve weeks. If they are in care at separate times, you can claim for each, with twelve weeks as the overall total. The cap is on the parent, not on the baby.

Sixty-eight weeks is a long runway, and that is the point

Everything has to be taken within 68 weeks of the birth — just under sixteen months. That is generous by statutory standards and it exists for a reason: families with a baby in neonatal care are rarely in a position to plan leave in the moment, and a great deal of the emotional and practical fallout arrives months later, after the maternity leave has run out and everyone else has moved on.

Your employment rights are protected throughout. Pay rises, accrued holiday and the right to return all continue as they would on any other family leave.
