Nanny Share vs Solo Nanny Cost UK 2026
A nanny share splits one nanny's wage, tax and National Insurance costs between two families, roughly halving the cost per family compared to employing a nanny solely for your own children — at the cost of needing compatible schedules, house rules and children who get on. A solo nanny is more expensive per family but gives you complete control over routine, house rules and one-to-one attention for your own children.
At a Glance
| Feature | Nanny Share | Solo Nanny |
|---|---|---|
| Typical UK cost per family | £350–£550/week (split with the other family) | £500–£800+/week (full cost falls on you) |
| Employer responsibilities | Shared — usually one family runs PAYE, or a nanny payroll agency handles both | Full employer responsibility (PAYE, pension auto-enrolment, holiday pay) |
| Attention per child | Divided between two families' children | Full one-to-one or one-to-few attention on your own children |
| Flexibility | Constrained by both families' schedules and holiday dates | Fully flexible to your own family's schedule |
| Setting up the arrangement | Requires finding a compatible family and agreeing terms | Simpler — one employer, one contract |
| Tax-Free Childcare / voucher eligibility | Yes, if the nanny is registered with Ofsted or a childminder agency | Yes, if registered |
When Nanny Share Wins
- You want quality one-to-one style nanny care but cannot afford it solo
- You can find a compatible family nearby with similar-aged children and schedule needs
- Your children benefit from socialising with another family's children
When Solo Nanny Wins
- You need full flexibility over hours, routine and house rules
- Your work schedule is unpredictable and incompatible with sharing
- You have multiple children and the per-child cost of a solo nanny already compares favourably to nursery
Frequently Asked Questions
Do I still need to register as an employer for a nanny share?
Yes — each family employing a share of a nanny's time is technically a joint employer (or the arrangement is structured with one lead employer), and PAYE, employer's liability insurance and pension auto-enrolment duties still apply. Most families use a specialist nanny payroll service to manage this correctly, since HMRC registration and RTI submissions are still required.
How is a nanny's pay split in a share arrangement?
Typically the total wage is split 50/50 between the two families if they take equal hours and have an equal number of children, though many families weight the split by number of children (e.g. 60/40 if one family has two children and the other has one), and this should be agreed and documented before starting.
Is a nanny share cheaper than a nursery?
It depends on the region and the nanny's rate, but a nanny share often works out similar to or slightly more expensive than nursery per child once tax, NI, holiday pay and pension contributions are factored in, though it offers far greater flexibility and one-to-one attention.

What happens if one family in a nanny share wants to end the arrangement?
This should be addressed in the initial agreement between both families and the nanny — typically a notice period is agreed (e.g. 4–8 weeks) so the remaining family and the nanny have time to find a new sharing family or adjust the arrangement to solo employment.
Can Tax-Free Childcare be used for a nanny?
Yes, but only if the nanny is registered with Ofsted (or the equivalent regulator in Scotland, Wales or Northern Ireland) or with an approved childminder agency — unregistered nannies do not qualify for Tax-Free Childcare, childcare vouchers or the free childcare hours entitlement.
