Sleep-In Shifts and the National Minimum Wage: What Care Providers Must Know
The Supreme Court settled the headline question in 2021 — but “settled” doesn’t mean “safe to ignore.” Sleep-in pay is still one of the easiest ways for a care provider to end up with a five-figure back-pay bill.

Sleep-in shifts — where a worker stays overnight and is available if needed, but isn’t actively working the whole time — have been a source of genuine legal uncertainty in care for years. The Supreme Court’s ruling in Royal Mencap Society v Tomlinson-Blake settled the core legal question in 2021, but the practical compliance risk for providers hasn’t gone away — it’s just better defined.
What the Supreme Court Actually Decided
Under the National Minimum Wage Regulations 2015, a worker must be “awake for the purpose of working” for time spent at work to count as working time. The Supreme Court confirmed that sleep-in workers are only entitled to the National Minimum Wage for the time they’re actually awake and working — not for the hours they’re simply present and permitted to sleep. A worker who is present but not actively carrying out duties, even with an ongoing obligation to respond if needed, is not automatically “working” for NMW purposes during that time.
In practice, this means a flat overnight rate for the sleeping portion of a shift, plus full NMW for any time genuinely spent awake and working, can be lawful — provided the arrangement is structured correctly.
The Exception That Catches Providers Out
The ruling isn’t a blanket green light. If suitable sleeping facilities are not actually provided, the analysis changes, and NMW can become due for the entire shift — not just the awake portion. “Suitable” is a factual question, not a box-ticking exercise: a room that technically exists but isn’t realistically usable for sleep (no bed, shared with another purpose, inadequate privacy or safety) may not meet the standard, regardless of what the staff rota or contract says.
Risk pattern
A designated “sleep room” that’s rarely actually usable in practice — shared, uncomfortable, or frequently interrupted — while pay is still structured as if suitable facilities exist.
Defensible position
A genuinely usable, private sleeping space, a clear record of when workers were actually called on to work during the shift, and pay structured to reflect both the flat rate and any awake-working time accurately.
2026: A New Enforcement Body Changes the Picture
From 7 April 2026, the Fair Work Agency (FWA) begins operating as the UK’s single labour market enforcement body, replacing HMRC’s standalone National Minimum Wage enforcement function and consolidating several enforcement streams under one structure. For care providers, this means NMW compliance — sleep-ins included — now sits under a more joined-up, and likely more visible, enforcement regime than the fragmented approach that came before it. New National Minimum Wage rates also apply from 1 April 2026, which is a useful prompt to review sleep-in pay structures alongside the general rate uplift rather than treating the two as separate exercises.
The Wider Risk Areas Beyond Sleep-Ins
Sleep-ins get the most attention, but they’re not the only recurring NMW risk in the care sector. The other genuine compliance risk areas are:
- Travel time between calls — particularly relevant in domiciliary care, where unpaid or under-recorded travel time can quietly erode effective hourly pay below NMW
- Unlawful deductions — uniform costs, training charges, or other deductions that push effective pay below the minimum
- Salaried-hours contract structures — where the calculation method itself, not just the headline rate, determines compliance
- Record-keeping gaps — if you can’t evidence what was actually worked, you can’t evidence compliance either, regardless of intent
Genuine underpayment carries real financial exposure
Where an underpayment is identified — including through a sleeping-facilities finding — providers can face arrears going back years, penalties of up to 200% of the underpayment, and public naming. This compounds quickly across a whole staff team and multiple pay periods, which is why proactive review matters more than a reactive fix after a complaint or inspection.
Keep sleep-in and shift records defensible, not just compliant on paper
CQCLogic’s Compliance Tracker logs actual overnight activity against each sleep-in shift, so you have a genuine, timestamped record of awake-working time — not just a rota that assumes compliance rather than evidencing it. See the full feature or view a sample plan.
Summary: Sleep-Ins and the National Minimum Wage
- Sleep-in workers are entitled to NMW only for time genuinely awake and working, per Royal Mencap Society v Tomlinson-Blake
- If suitable sleeping facilities aren’t actually provided, NMW can be due for the whole shift
- “Suitable” is a factual, not a paper, standard
- The Fair Work Agency takes over NMW enforcement from 7 April 2026, alongside new rates from 1 April 2026
- Travel time, deductions, salaried-hours structures, and record-keeping are equally real compliance risk areas beyond sleep-ins
- Genuine underpayment risks years of arrears, penalties up to 200%, and public naming
Frequently Asked Questions
Do care workers have to be paid the National Minimum Wage for the whole sleep-in shift?
Not automatically. Following the Supreme Court’s ruling in Royal Mencap Society v Tomlinson-Blake, sleep-in workers are only entitled to the National Minimum Wage for time they are actually awake for the purpose of working, not for time they are simply present and permitted to sleep. Time spent asleep, with no work being carried out, does not count as working time for NMW purposes under this ruling.
Is there ever a situation where the whole sleep-in shift must be paid at NMW?
Yes. If suitable sleeping facilities are not actually provided, the analysis changes and the National Minimum Wage can be due for the entire shift, not just time spent awake and working. Whether facilities are genuinely “suitable” is a factual question, not just a box to tick — a room that exists on paper but isn’t realistically usable for sleep may not meet the standard.
What is the Fair Work Agency and how does it affect care providers?
The Fair Work Agency (FWA) begins operating from 7 April 2026 as the UK’s single labour market enforcement body, replacing HMRC’s standalone National Minimum Wage enforcement function and bringing several enforcement streams under one structure. For care providers, this means NMW compliance — including sleep-in arrangements — sits under a more consolidated, and likely more visible, enforcement regime than before.
What are the penalties for underpaying sleep-in workers?
Where a genuine underpayment is identified — for example because sleeping facilities weren’t actually suitable, or a worker was required to be awake and working more than recorded — providers can face arrears going back years, financial penalties of up to 200% of the underpayment, and public naming. The financial exposure from getting sleep-in pay wrong compounds quickly across a staff team and multiple pay periods.
Where do care providers commonly get NMW compliance wrong beyond sleep-ins?
The recurring risk areas for care sector NMW compliance are travel time between calls (particularly in domiciliary care), unlawful deductions from pay, sleep-in arrangements, how salaried-hours contracts are structured, and gaps in record-keeping that make it hard to evidence what was actually worked. Sleep-ins tend to get the most attention, but the other four areas cause just as many genuine compliance failures.
