How many rounds of interviews should I do with a nanny?

Most families do two: an initial conversation to check fit on the basics, followed by a more detailed in-person interview at your home. A paid trial day usually follows before a final decision.

Should the children be present during the interview?

It is often helpful to have them present for at least part of it, so you can observe how the candidate interacts with them naturally. Many parents split it: start without the children, then bring them in towards the end.

What documents should I ask to see at interview?

At or before interview you should ask to see: proof of identity, evidence of right to work in the UK, relevant qualification certificates (paediatric first aid in particular), their DBS certificate if they have one, and their driving licence if driving is part of the role.

Is a trial period mandatory before hiring a nanny?

It is not a legal requirement, but it is strongly recommended. A paid trial of one or two days gives both sides the chance to see whether the arrangement works in practice. During a trial, you as the parent remain responsible for the children at all times.

How do I know if I need to register as an employer?

If you are paying a nanny more than the Lower Earnings Limit (currently 125 pounds per week as of 2025/26), you will need to register as an employer with HMRC, operate PAYE, and pay employer's National Insurance contributions.
