What Does a Nanny Actually Cost in 2026? Here's What UK Parents Need to Know
Thinking about hiring a nanny? Whether you're heading back to work after maternity leave or finding nursery doesn't fit your hours, the same question stops most parents in their tracks: what will it actually cost?
When you hire a nanny, you become a legal employer. That means there are costs on top of the salary you agree:
1. The Nanny's Gross Salary(the amount you agree on).
2. The "On-Top" Employer Costs(the tax and pension you pay).
This guide will break down both parts so you can build a realistic budget.
1. The Nanny's Gross Salary
The gross salary is the amount you agree on with your nanny before any deductions. Nannies are employees, so their pay is quoted gross (before income tax and National Insurance are taken off), just like any other job.
This salary depends on several key factors:
Location
Average gross hourly rates vary across the UK depending on location, experience, and qualifications. Whereas in London rates can cost over £20/hour, in more rural areas such as in Northern Ireland it’s around £13/hour.
Live-in vs. Live-out
Live-in nannies typically earn a lower gross salary because accommodation and meals are provided. Live-out nannies are more common and generally earn more to cover their own living and commuting costs.
Experience and Qualifications
A highly qualified nanny with 10 years of experience, glowing references, and an Ofsted registration will command a higher salary than a junior nanny just starting their career.
One thing worth getting right from the start: always agree on a gross salary, not a net (take-home) figure. Not only would you end up responsible for covering all the tax, the National Insurance, and pension contributions, but if their tax code changes at any point, your costs could increase without any warning. Gross is the right basis for any employment agreement.
2. The "On-Top" Employer Costs
Your legal duties as an employer add a significant, non-optional cost on top of the gross salary.
Employer's National Insurance This is a tax paid by you, on top of your nanny's wages — separate to the National Insurance your nanny contributes themselves. At the current 2026/27 rate of 15% on earnings above the secondary threshold, it adds up to a meaningful sum over the year.
Workplace Pension Contributions You're legally required to enrol eligible nannies into a workplace pension and contribute a minimum of 3% of their qualifying earnings on top of their salary. This applies automatically once your nanny meets the eligibility criteria.
Employer's Liability Insurance This is a legal requirement from day one of employment. Most families add it to their existing home insurance policy.
Then there are the smaller ongoing costs: agreed nanny expenses like activities and mileage, and costs linked to Ofsted registration, where it’s common for the employer to cover the annual registration fee.
To put this in real terms: a nanny working 40 hours a week in the South east at the average local rate of £16.60 per hour has an annual gross salary of around £34,528. Once you add Employer's NI and pension contributions, the total annual cost to you is closer to £39,805. That's roughly an extra £5,277 on top of the agreed salary.

Hiring a nanny is a big decision but it doesn't have to be a complicated one. Once you know what you're actually budgeting for and the payroll side is taken care of, it really does fall into place.
If you want to take the admin off your plate entirely, quinn is worth a look. One thing many parents don't realise: finding a nanny and paying a nanny are two different jobs. If you use an agency, their work is largely done the week your nanny starts, while payroll carries on every payday after that. It's also worth knowing that not all payroll options work the same way.
