For most UK families with one child under three, the realistic choice is between a place at a nursery (or with a childminder) and hiring a nanny to come to the house. The decision is partly financial, partly logistical, and partly about what suits your specific child and life. Neither option is inherently better; each has a profile that fits some families and not others. This article walks through both honestly. Healthbooq supports the running of either model.
What a Nanny Actually Does
A nanny is employed by you (you are the employer for tax, NI, pension, and employment-rights purposes), works in your home, and looks after your child during agreed hours. Most UK nannies do:
- Sole charge of the child during contracted hours
- Bottle / breast-milk feeds, weaning, meals
- Naps and bedtime where applicable
- Walks, soft play, swimming, library, playgroups, parks
- Light child-related housework: child laundry, tidying play areas, cleaning bottles, preparing the child's food
- Trips out, sometimes with the family car
A nanny is not a housekeeper, cleaner or PA, although the boundary slips in some families. Anything beyond child-related work needs to be in the contract and reflected in the wage.
What a Nursery Actually Provides
A regulated group setting (in England, Ofsted-registered) where:
- Trained staff care for groups of children at statutory ratios (1:3 under two, 1:4 for two-year-olds, 1:8 or 1:13 for three- and four-year-olds depending on staff qualifications)
- A key person system assigns each child a named adult responsible for their settling, learning records, and parental relationship
- A structured daily routine includes meals, outdoor time, planned activities, free play, story times
- Statutory safeguarding, health, and education frameworks apply
- Inspection by Ofsted (or equivalent in Wales/Scotland/Northern Ireland) provides external oversight
The same is broadly true of registered childminders, but in a smaller home-based setting with one adult and a small mixed-age group.
What the Cost Looks Like in 2026
Nanny costs in the UK in 2026:
- Live-out nanny outside London: £14–18 net/hour, often quoted as ~£600–800/week net for full-time
- Live-out nanny in London: £18–25 net/hour, ~£800–1,200/week net
- Live-in nanny: £20,000–28,000 gross/year plus board outside London, more in London
- Employer's contribution on top: add roughly 25–40% — employer's NI, pension auto-enrolment (3% of qualifying earnings), holiday pay, sick pay accrual, and the fact that you are paying gross to net conversion
Net-to-gross example: a nanny on £800 net/week costs the family roughly £1,100–1,200 gross/week including employer's NI and pension. Annual cost £55,000–60,000 outside London for a full-time nanny — and substantially more in London.
Nursery costs:
- Full-time under-2: £290–360/week outside London, £400–520 in London (£15,000–27,000/year)
- Full-time 2-year-old: roughly 5–10% less
- 3- and 4-year-olds: dramatically less after funded hours apply
- Childminder: £55–80/day outside London, more in London
For one child, nursery is generally cheaper. For two children under three at the same time, the nanny becomes competitive — one nanny for two children is the same price; two nursery places double up.
Where Each Option Wins
Nanny wins on:
- One-to-one attention for the youngest babies
- Flexibility — exact hours, last-minute changes, late finishes
- Low illness exposure (less group bug spread)
- Care continuity if you have non-standard hours
- Multiple children at the same time (cost-effective)
- Care in the home environment
- A child who finds groups overwhelming
- Tailored routines, food, and approach
Nursery / childminder wins on:
- Cost (especially for one child)
- Peer interaction — a real benefit from about 18 months
- Structured early-years curriculum (EYFS)
- Backup when one staff member is sick
- Regulatory oversight and safeguarding framework
- Trained staff and continuing professional development
- A more diverse environment for the child
- Funded hours easier to use
- Clean separation between work and home life
Where the Conventional Wisdom Is Half Right
A few often-quoted points that need a more nuanced version:
"Nurseries socialise babies." Babies under twelve months mostly engage in parallel observation rather than genuine peer interaction. The socialisation benefit of group care is real but kicks in more from 18 months. Under one, a nanny or a childminder gives essentially equivalent social experience for a baby — neither is meaningfully social yet.
"Nannies offer one-to-one attention." True, but the quality of that attention varies hugely. A nanny on a phone for half the day with one child is providing less attentive care than a key worker absorbed with three babies. Visit, observe, and check.
"Nurseries get sick all the time." Mostly true and often blown out of proportion. The first six months of nursery for an under-three is typically a series of viral illnesses; by the second year most children have built immunity and rarely miss days. Childminders, with smaller groups, have less illness spread.
"Nannies are unregulated." Partly true. Nannies are not Ofsted-registered by default; they can register voluntarily on the Voluntary Childcare Register (which makes you eligible for Tax-Free Childcare). The register is light-touch but does require basic safeguarding training. Background checks (Enhanced DBS) are reasonable to require.
The Hours and Logistics Test
Practical questions that often determine the answer:
- What hours do you actually need? A nursery with a 6pm hard close and a 10-minute-late-fine does not work for parents with unpredictable end-of-day meetings.
- Where are you working? Drop-off near work versus near home affects daily routine.
- What happens when your child is ill? A nursery excludes them; a nanny stays. Many families have no realistic backup when a child is excluded from nursery; the nanny model handles this.
- What happens when the carer is ill? A nursery has substitutes; a nanny does not. You are the back-up.
- Holidays. Many nurseries close for two weeks a year and you pay anyway. Many nannies have four to five weeks of holiday — you choose two and they choose two-three.
The cost calculation is sometimes shaped by hidden assumptions about who bears the back-up burden when each option breaks.
Quality: What to Watch For With Each
Nursery quality cues:
- Adults at children's eye level, naming what is happening
- Settled, absorbed children rather than wandering or watching the door
- Same key person caring for the same baby across the day
- Daily outdoor time
- Ratios respected, not stretched at start and end of day
- Staff who seem calm and pleasant with each other
- A clear, named key person you can speak to
- Honest itemised costs
Nanny quality cues, observed during a paid working interview:
- Engaged, focused interaction with your child
- Phone in pocket, not in hand
- Comfortable on the floor with the child
- Asks specific questions about your child rather than waiting for instructions
- Initiative — suggests an activity rather than asking what to do
- Confident with feeding, nappy, settling
- Has a paediatric first aid certificate
- References that hold up to phone calls
The Employer Side of a Nanny
Things many parents do not know going in:
- You are responsible for PAYE tax, employer's NI, employee NI, and pension auto-enrolment.
- Most families use a payroll company (Nannytax, Nannypaye, Stafftax) at around £200–300/year — saves time and embarrassment.
- A written contract is required.
- Statutory holiday is 5.6 weeks (28 days for full-time including bank holidays).
- Statutory sick pay applies once they have been with you long enough.
- You're responsible for tax conduct — paying gross to net is illegal-ish and unenforceable for the nanny when they later need NI credits.
- Maternity, paternity, and parental leave statutory rights apply.
- Termination has notice periods (statutory minimum or contract whichever is greater).
This is doable but it is real. Do not under-budget the gross-to-net conversion; many families negotiate net wages and then find the gross is much higher than expected.
Hybrid Models
Many UK families with non-standard situations build a hybrid:
- Nursery part-week + nanny part-week — peer interaction plus flexibility
- Nanny share — two families share one nanny, halves the cost, adds a peer
- Childminder + occasional nanny — most days at the childminder, nanny for late finishes
- Nursery + grandparent days — typical UK pattern, nursery covers core days, grandparent does one or two
Hybrids work well if the child has consistent key relationships in each setting. They struggle if the child is bouncing between four different carers a week with no continuity in any.
Reviewing the Choice
The right answer changes as a child grows. A workable plan is:
- Under 12 months: nanny or childminder, if affordable
- 12–24 months: any model works for most children; childminder is often the sweet spot
- 2 years+: group setting offers real benefits; consider nursery for at least part of the week
- 3+ years: nursery or pre-school for the structured early-years experience
Most families re-evaluate at each major transition: end of maternity leave, second birthday, third birthday with funded hours, school start. None of the choices are permanent.
Key Takeaways
A nanny gives one-to-one, in-home, flexible care at the highest cost; a nursery gives peer-rich, structured, regulated care at lower cost per child. For one child the maths usually favours nursery; for two or more under three, a nanny becomes competitive. The choice should also weigh hours, location, and the temperament of the specific child.
