A baby born eight weeks early doesn't come with a memo to HR. The mother is on maternity leave from day one, as she should be. But her partner, back at his desk after two weeks of statutory paternity leave, is now commuting to a neonatal unit every evening and has nothing left to draw on — no annual leave built up, no obvious box to tick on the absence form. Most managers, when asked, guess at something. Some point him towards unpaid parental leave, which technically exists but caps out at eighteen weeks across a child's entire childhood and requires notice he doesn't have time to give. Very few guess right, because the right answer only became law in April 2025, and a surprising number of UK employers still haven't updated their handbook to reflect it.
That right is Neonatal Care Leave and Pay, created by the Neonatal Care (Leave and Pay) Act 2023 and in force since 6 April 2025 across England, Scotland and Wales. It gives parents of babies who spend an extended stretch in neonatal care a distinct entitlement, separate from maternity, paternity and shared parental leave — up to 12 additional weeks, on top of whatever else they're already using. Eighteen months in, it's still being applied inconsistently, and the gaps tend to hurt exactly the families who can least afford an HR department's confusion.
What the Entitlement Actually Covers
Neonatal Care Leave (NCL) applies when a baby is admitted to neonatal care within 28 days of birth and stays there for at least seven full, consecutive days. That threshold matters: a three-day stay for jaundice monitoring doesn't qualify, however stressful it feels at the time, but a fortnight in special care after a premature birth clears the bar easily. Once triggered, each parent (not just the birth mother — a father, partner, or second parent with caring responsibility all qualify independently) can take one week of leave for every full week the baby has spent in neonatal care, up to a maximum of 12 weeks. The leave has to be used within 68 weeks of the birth, which in practice gives families room to take it either alongside the hospital stay or afterwards, once the baby is home and adjusting. It also applies to adoptive and surrogacy parents under the same 28-day and seven-day conditions. And it's counted in whole weeks only, so a short but qualifying stay still rounds up.
Crucially, this is a day-one right. There's no qualifying period for the leave itself — a parent who started their job three weeks ago is entitled to it exactly as much as someone with ten years' service. That surprises a lot of line managers, who instinctively reach for the same service thresholds that apply elsewhere in the handbook and end up telling a new starter they're not covered. They're wrong, and it's worth knowing that before the conversation happens, not after.
Leave Is One Thing. Pay Is a Different Test Entirely.
Here's the distinction that trips up almost everyone, employers and employees alike: qualifying for the leave does not automatically mean qualifying for the pay. Statutory Neonatal Care Pay (SNCP) has its own, stricter conditions. The employee needs 26 weeks of continuous service with their employer by the "relevant week" — for a birth, that's the 15th week before the expected week of childbirth — and average weekly earnings at or above the Lower Earnings Limit, which rose to £129 a week from 6 April 2026. Miss either threshold and the leave right still stands, but there's no statutory pay attached to it, which is a genuinely awkward conversation to have with someone whose baby is in an incubator.
Where both conditions are met, SNCP pays £194.32 a week from 6 April 2026 (up from £187.18 in the 2025/26 tax year), or 90% of average weekly earnings if that figure is lower — the same mechanism and broadly the same rate as statutory maternity, paternity and shared parental pay, uprated each April in line with September's CPI figure. It's paid for the same number of weeks as the leave itself, capped at 12, and it can't be paid for anything less than a full week. Some employers choose to enhance this — topping it up to full pay, the way many already do for maternity leave — but that's a discretionary policy choice, not a legal requirement, and it's the first thing worth deciding before a case lands on your desk rather than during one.
How It Sits Alongside Everything Else
Neonatal Care Leave doesn't replace maternity, paternity, adoption or shared parental leave — it runs in addition to them, which is the whole point of the Act. A mother on 52 weeks of maternity leave whose baby needed three weeks in neonatal care can, in principle, extend her total leave by three weeks beyond what maternity leave alone would have given her. In practice, though, the leave doesn't start ticking until the neonatal care leave period is triggered and the parent's own qualifying leave (maternity or paternity) has ended or been paused — the sequencing depends on individual circumstances, and getting it wrong is easy if you're mapping it against a standard maternity-leave spreadsheet built for a different entitlement entirely.
This is also where the mid-text caveat belongs, because it's the part employers most often skip: neonatal leave and pay are calculated per parent, not per baby, and for multiple births (twins, triplets) each qualifying baby's neonatal stay counts towards the total independently, up to the same 12-week cap per parent. A set of twins both in special care for ten days doesn't double the entitlement to 24 weeks — it's still capped at 12 per parent, calculated from whichever baby generates the longer qualifying period. Payroll software that hasn't been updated for this Act specifically will often get that calculation wrong, because it wasn't built with a "per parent, capped, based on the longer of concurrent stays" rule in mind.
What Employers Actually Need to Put in Place
A written policy is not optional in any meaningful sense, even though the Act itself doesn't demand one in so many words. Acas guidance recommends every employer have a neonatal care leave and pay policy that sets out eligibility, notice requirements, and how it interacts with other leave types — and in a tribunal, "we didn't have a policy" reads as negligence, not neutrality. For a business with fewer than fifty staff, that policy doesn't need to run to twenty pages; two clear pages covering who's eligible, how to notify HR, and what happens to pay will do the job and will do it better than a generic template copied from a larger company's intranet.
Three things are worth getting right from the outset:
- Update the payroll system (or brief whoever runs it externally) so SNCP calculates correctly against the current £194.32 rate and the 26-week service test — don't assume a system update happened automatically just because the law changed eighteen months ago.
- Train line managers specifically on the day-one right for leave versus the 26-week test for pay, because this is the single most common point of confusion and the one most likely to produce an unlawful refusal.
- Set a clear, low-friction notification process. The Act allows notice to be given informally in urgent situations (a phone call from the neonatal ward counts), with the formal written notice — required within 28 days of the first day of neonatal care pay being claimed — following once things have calmed down a little.
We'd recommend enhancing the pay if the business can genuinely afford it, particularly for smaller employers competing for talent against companies that already offer full-pay parental leave — a family that remembers being supported through a neonatal stay tends to remember it for the rest of their working relationship with you. What we wouldn't recommend is treating this as a box-ticking compliance exercise bolted onto an existing maternity policy at the last minute, because that's exactly the approach that produces the calculation errors and refusal-by-ignorance cases now starting to surface at employment tribunals.
Where People Actually Get This Wrong
On the employee side, the most common mistake is assuming eligibility hinges on length of service, which puts people off asking at all — plenty of new parents in their first few months of a job never raise it, wrongly believing they don't qualify for anything. On the employer side, the reverse mistake shows up just as often: assuming that because the leave is a day-one right, the pay must be too, and then having to walk back a payment commitment once payroll flags the 26-week service gap. Neither mistake is malicious. Both are avoidable with a one-page reference sheet that separates the two tests clearly, which is more useful in practice than a detailed legal briefing nobody reads under pressure.
There's also a quieter failure mode worth naming: HR teams that get the entitlement right but handle the conversation badly, treating it as an administrative process rather than what it actually is — a family going through one of the hardest stretches of their working life. The Act gives the legal framework; it doesn't give anyone a script for how to talk to a parent whose baby is still in an incubator, and that part still depends entirely on the manager in the room.
What to Do Next
If you're an employee whose baby has spent, or is spending, a week or more in neonatal care, check your contract and staff handbook for a neonatal leave policy first; if there isn't one, ask HR directly and cite the Neonatal Care (Leave and Pay) Act 2023 by name, since a specific legal reference tends to get a faster, more accurate answer than a general query. Keep a simple record of the admission and discharge dates from the neonatal unit — you'll need them to establish the qualifying seven-day stretch, and hospitals will usually confirm this in writing on request.
If you're running a small business without a dedicated HR function, the fix is smaller than it sounds. Acas publishes a free model policy that covers the notification process and the leave-versus-pay distinction in plain language, and most payroll providers (Xero, Sage, and BrightPay all confirmed SNCP support well before the April 2025 start date) will calculate the statutory rate automatically once the employee's details are entered correctly. Spend an hour on this before you need it. The alternative is working it out in real time, on the phone, while someone on the other end of the line is standing in a hospital corridor.
