The short answer: does 24 hours mean 24 hours of pay?
No. A live-in carer present in a client's home for a full day is owed the National Minimum Wage for the time they are actually working, not for every hour they are on the premises. This is the single biggest misunderstanding in live-in care, and it cuts both ways: some owners assume they must pay 24 hours at £12.71 and panic about the maths, while others pay a flat daily rate that quietly falls below the minimum once you divide it by the real working hours.
The reason is how the rules classify the work. The minimum wage regulations split work into categories, and live-in care almost always falls under "unmeasured work", where the hours are not set by a clock or a rota in the ordinary way. For unmeasured work you either pay for every hour the worker is available, or you agree the hours in advance through a daily average agreement. That agreement, covered in the next section, is the mechanism that lets a live-in placement work without paying 24 hours a day, and it is also the document HMRC asks to see first.
Two numbers anchor everything that follows. The rate is £12.71 an hour for a carer aged 21 or over from 6 April 2026, up from £12.21 the year before, per the gov.uk minimum wage rates. Younger carers sit on lower age bands. The look-back is up to six years, which is how far HMRC can go when it finds an underpayment. Keep both in mind as you read.
How the hours are counted: the daily average agreement
A daily average agreement is a written agreement between the agency and the carer that states the average number of hours the carer is likely to spend working each day of a live-in placement. Only those hours have to be paid at the minimum wage, which is what makes a 24-hour placement commercially workable without paying a 24-hour rate.
HMRC's own manual is specific about this. Under the guidance on ascertaining hours for unmeasured work, the time treated as worked in a pay reference period is set by reference to the agreement, provided the agreement is valid. Three conditions make it valid, and all three matter.
First, it has to be in writing and signed before the start of the pay reference period it covers. You cannot draft one retrospectively after a query lands. Second, it has to state a realistic average of the hours the carer actually spends working. Third, that figure has to stand up: if the real pattern of the placement means the carer routinely works more than the stated average, the agreement fails and HMRC treats the true hours as the working hours. An agreement that says eight hours when the carer is on their feet for eleven is not protection, it is exposure.
This is where the honest version of live-in care matters. The daily average agreement is not a device to pay less than the work is worth. It is a way of reflecting that a live-in day genuinely includes active care, time the carer is free to rest, and a night where they are usually allowed to sleep. The chart below shows how a typical 24-hour booking breaks down, and why the pay you set has to cover the active hours at £12.71 or more.
One practical point that catches agencies out: the agreement covers the average, but you still have to check the reality every so often. If a client's needs increase and the placement drifts from ten working hours to fourteen, the old agreement no longer reflects the work and the pay has to move with it. We usually build a light quarterly review into the payroll routine so the agreements never fall out of date silently. For the domiciliary version of this same averaging problem across visits and travel, our guide on minimum wage averaging for domiciliary carers works through the pay-reference-period maths in detail.
Sleep-ins are different: what the Mencap ruling changed
A sleep-in shift is not the same as a live-in placement, and the rule that governs it is different. On a sleep-in, following the Supreme Court decision in Royal Mencap Society v Tomlinson-Blake in March 2021, a worker who is permitted to sleep is only entitled to the minimum wage for the time they are awake and working, not for the whole shift.
The facts of that case are worth knowing because they set the line. The carer slept at a service user's home to be available if needed, had her own bedroom, and was paid a flat allowance plus one hour's pay. The Court held that simply being present and available to respond, while asleep, was not "work" for the minimum wage. Only the periods she was actually awake and dealing with something counted. The gov.uk guidance on different types of work reflects this distinction between being available and actually working.
Why does this matter for a live-in agency? Because many agencies run both patterns. A live-in carer in a placement is usually unmeasured work with a daily average agreement. A separate night carer covering a sleep-in at a supported living house is on the Mencap rule. Mixing the two up, or applying the sleep-in logic to a live-in placement, is where the calculations go wrong. Document which shift is which, and pay each on its own rule. If you also run residential night cover, our note for care home owners on sleep-in shifts and the minimum wage covers that setting specifically.
Can a live-in carer be self-employed? The question that decides your PAYE bill
Usually not, when the agency controls the work. Whether a carer is genuinely self-employed or is a worker or employee is not decided by what the contract calls them. It is decided by the reality of the arrangement, tested against the same employment status factors HMRC applies everywhere else. Labelling a carer a self-employed contractor when you roster, train, control and pay them is the single most expensive mistake we see in this sector.
The pull towards self-employment is understandable. It looks like it removes employer National Insurance, holiday pay, pension auto-enrolment and payroll admin at a stroke. In practice, if the substance is employment, none of that liability actually disappears. It just sits there unpaid until a carer brings a tribunal claim or HMRC opens a check, and then it lands as backdated PAYE, National Insurance, holiday pay and minimum wage across the whole affected group. The gov.uk employment status guidance sets out the categories, and the factors below are what an inspector or a judge weighs.
There is a genuine exception. A true introductory arrangement, where the agency only matches a self-employed carer to a private client and then steps back, without controlling the work, setting the pay or guaranteeing the hours, can be self-employment. But it has to be real. If you are still rostering the carer, handling the client's money, covering absences and directing the care, an "introductory" label on the paperwork will not survive a look at the substance. When we onboard a live-in agency, checking which model they are genuinely running is one of the first things we do, because it changes the entire payroll and tax picture. Our guide on employed versus self-employed carers and the status risk works through where the line actually sits.
The upcoming employment law changes make this worth resolving now rather than later. The Employment Rights Act 2025 received Royal Assent in December 2025, and its zero-hours and guaranteed-hours provisions are expected to take effect in 2027, with the exact commencement to be confirmed by regulations. Agencies that lean on loosely-defined self-employed or zero-hours arrangements have the most to reorganise, so getting the status right in 2026 is the calm way to do it.
The cost of getting it wrong: arrears, penalties and public naming
An underpayment on a single carer is a nuisance. The same error across a workforce is a serious liability, and that is exactly how minimum wage mistakes arrive in care, because the pay model is usually applied identically to everyone.
When HMRC finds an underpayment, three things happen. It requires the arrears to be paid, and it calculates them at the current minimum wage rate, not the rate that applied at the time, which inflates historic shortfalls. It can look back up to six years. And it can charge a penalty of up to 200 percent of the underpayment, reduced if the employer settles quickly. On top of all that, HMRC operates a public naming scheme for employers who underpay, which for a care agency bidding for council and NHS contracts is a reputational problem as much as a financial one.
Run the arithmetic on a mid-sized agency. If twelve live-in carers were each underpaid by an average of £40 a week because a daily average agreement understated their hours, that is £480 a week, roughly £25,000 a year, and across a few years plus the penalty it becomes a five-figure or low six-figure exposure very quickly. None of it is exotic. It is the same small error repeated, which is precisely why it is worth designing out at the pay-run level rather than hoping it never surfaces.
The regulators are joined up on this too. The Care Quality Commission looks at whether a provider is well-led and financially sustainable, and a provider carrying an unquantified minimum wage liability is neither. The Homecare Association publishes a minimum price for homecare precisely because pay compliance depends on being funded properly in the first place. Getting the pay right and getting the funding right are two halves of the same problem.
Here is how the three common approaches actually compare for live-in care minimum wage compliance:
| What a live-in agency needs | Payroll software alone | Generic accountant | LOYALS care specialist |
|---|---|---|---|
| Drafts daily average agreements that hold up to HMRC | ✗ Not its job | ● If asked | ✓ Built into onboarding |
| Splits live-in from sleep-in on the correct NMW rule | ✗ | ● Often missed | ✓ Per shift type |
| Tests carer employment status before it becomes a bill | ✗ | ● | ✓ Status review at start |
| Checks pay clears £12.71 after breaks and travel time | ● Only if configured | ✗ | ✓ Every pay run |
| Understands welfare VAT and council or NHS funding | ✗ | ✗ | ✓ Care sector day to day |
| Open Mon to Sat when a commissioner query lands | ✗ | ✗ Mon to Fri 9 to 5 | ✓ 10am to 7pm Mon to Sat |
This is why live-in and home care agencies tend to move from a generic accountant to a care specialist once the minimum wage stakes are clear.
What proper live-in payroll actually costs to run
For a live-in or home care agency, getting minimum wage compliance handled properly runs from £995 a month plus VAT, which buys the payroll, the daily average agreements and the ongoing compliance rather than just a return at the year end. That is deliberately not a bargain-basement number, because the work that keeps you out of a six-year arrears claim is not bargain-basement work.
The value is in what sits underneath the fee: agreements that match the real hours, a pay run that checks every carer clears £12.71 after breaks and travel are counted, the live-in and sleep-in rules applied correctly, and a status position you can defend. When a commissioner or an inspector asks how you know your carers are paid legally, you have the answer ready instead of a weekend of panic. LOYALS is a King's Cross firm of chartered accountants that runs weekly payroll, daily average agreements and minimum wage checks for London live-in and home care agencies, so this is the work we do every week rather than once a year. The pricing box below is drawn from our live care agency tiers.
What this typically costs at LOYALS
- Care Payroll and Compliance (up to 25 carers): from £995 a month
- Care Finance Department (up to 50 carers, management accounts and weekly credit control): from £1,495 a month
- Historic NMW compliance review: £595 one-off
All fees exclude VAT and are fixed for twelve months. Quotes are issued in writing within 24 hours after a 15-minute call, and we do not take on ongoing work below £500 a month. See full price list.
What to do before your next pay run
You do not need to overhaul everything at once. Work through these in order and the position tightens quickly.
- Pull one live-in placement and check the maths. Take the pay, divide by the genuine working hours for the week, and confirm it clears £12.71 for a carer aged 21 or over. If it does not, you have found your first fix.
- Find the daily average agreements. Confirm each one is signed, dated before the pay period it covers, and states hours that match reality. Any that are missing, unsigned or stale go to the top of the list.
- Separate live-in from sleep-in. Label every shift pattern and confirm you are applying the unmeasured-work rule to live-in placements and the Mencap awake-time rule to sleep-ins.
- Stress-test any self-employed carers. Run the five status factors honestly. If you roster, control and depend on them, plan to move them onto payroll before it becomes a claim.
- Count travel and breaks properly. For carers doing visits between placements, unpaid travel time is the most common way pay slips below the minimum. Our guide to mileage and travel time for domiciliary care covers this.
- Set a quarterly review. Placements change. Build a short recurring check so agreements and pay never drift out of date silently.
Done in that order, most agencies find they are closer to compliant than they feared, with two or three specific fixes rather than a wholesale rebuild. The agencies that get caught are the ones that never look, because the same small error compounds quietly across the workforce until someone else finds it first.
