Employing a nanny can be one of the best decisions a family makes. A professional nanny brings stability, care and consistency into a child’s daily life, often becoming a trusted and much-loved part of the household.
But hiring a nanny isn’t just arranging childcare – it means becoming an employer. Many parents are surprised to learn this. Although the arrangement can feel informal because the nanny works in your home, UK employment law still applies, and in most cases a nanny is legally classed as an employee rather than self-employed.
Understanding your responsibilities from day one helps you avoid the most common pitfalls and sets the relationship up to last. Here’s what every UK family should know.
You Become an Employer
Once you hire a nanny, you take on an employer’s legal obligations — covering tax, contracts and employment rights. Treating the role informally, without recognising this, is where most problems start.
PAYE and Tax
One of the biggest responsibilities is running PAYE (Pay As You Earn) through HMRC. In practice, this means you need to:
– Deduct Income Tax and National Insurance from your nanny’s salary
– Pay the employer’s National Insurance contributions
– Provide payslips
– Report wages to HMRC
Paying through PAYE gives your nanny proper employment records, pension eligibility and statutory protections. Because the admin can be fiddly, most families use a dedicated nanny payroll service to handle it correctly from the outset.
Employer’s Liability Insurance
If you employ a nanny, you’re legally required to have Employer’s Liability Insurance. This protects you if your nanny is injured at work or brings an employment-related claim. Many standard home insurance policies don’t automatically include this cover, so it’s worth checking carefully.
The Contract Is the Foundation
A nanny contract isn’t just paperwork to file away. It’s the document that sets expectations, boundaries and responsibilities for both sides. Done well, it protects everyone and gives clarity about how the role actually works day to day.
A strong contract typically covers:
– Salary and payroll arrangements
– Working hours and guaranteed hours
– Overtime expectations
– Holiday entitlement
– Sick pay
– Duties and responsibilities
– Use of a car and expenses
– Notice periods
When these details are written down clearly from the start, misunderstandings become far less likely.
Top tip: Family life evolves – children grow, schedules change, needs shift. Treat the contract as a living document, reviewed periodically, rather than something signed once and forgotten.
Guaranteed Hours (and the Trouble with “Banking” Them)
Guaranteed hours – paying a nanny their full contracted hours every week, even during quieter periods – are considered best practice. Some families try “banking hours” instead: fewer hours one week, extra the next. This can easily create legal or contractual problems, particularly around unpredictable income or unpaid overtime, and is a common root cause of relationship breakdowns between families and nannies. It’s best avoided.
Holiday Entitlement
Nannies are entitled to at least 5.6 weeks of paid holiday a year (28 days for full-time workers). Families should agree in advance how this works in practice – for example, whether the nanny chooses some holiday, some aligned with family travel, and whether bank holidays count towards the total. Clear expectations upfront prevent awkward conversations later.
Sick Pay and Illness
Illness is inevitable in a household with children, so it’s worth discussing early:
– Entitlement to Statutory Sick Pay (SSP)
– What happens if the nanny is unwell
– Arrangements if the children are sick
– Policies around contagious illness
Workplace Pensions
Under UK auto-enrolment rules, families may need to enrol their nanny in a workplace pension if certain age and salary thresholds are met, and contribute to the scheme. Many nanny payroll providers handle this automatically as part of their service.
Avoiding Role Creep
A nanny’s core responsibility is childcare, but extra tasks – household chores, errands, pet care – can quietly creep in over time.
If the role genuinely evolves (say, into a nanny-housekeeper or family assistant position), the contract, duties and salary should be updated to reflect that. The key is communication: assuming a nanny is happy to take on more, without discussing it, can leave them feeling undervalued and damage the relationship.
Expenses and Everyday Practicalities
Agree the small but important details early: how the nanny pays for outings and activities, how expenses are reimbursed, and whether they use their own car or the family’s (and who covers petrol and insurance). A prepaid card is a popular, low-hassle way to manage everyday costs.
Communication Is Key
Regular conversations about the children’s routines, upcoming schedules, and what’s working well (or not) help prevent small concerns turning into bigger problems – and make raising an issue feel routine rather than confrontational.
Notice Periods and Ending Employment
Nanny arrangements sometimes end when children start school, families relocate, or circumstances change. The contract should clearly set out notice periods for both sides, how notice should be given, and final pay arrangements, so the transition is handled professionally and fairly.
Professional Boundaries
Avoid asking your nanny to work for relatives or friends while you’re away – it can create complications around insurance, employment responsibility and safeguarding. Your household employs a nanny; other families should make their own arrangements.
Final Thoughts
Employing a nanny is a partnership built on professionalism, respect and clear communication. Families who understand their responsibilities – payroll, insurance, contracts and employment rights – are far more likely to build long-term, successful relationships with their nanny.
When expectations are clear, and both sides feel supported, the result is a stable, nurturing environment where children can truly thrive.
