Nannies work in the home of the children they look after and will fit in with unusual working hours. Some nannies live in, others come to work daily, and others work for two or more families. Unlike childminders, nannies do not have to be registered and inspected. However, they may choose to voluntarily register with Ofsted's General Childcare Register. The most important thing to check is that you feel they are a suitable person to care for your child. You must check any qualifications and follow up references yourself. You should have a proper contract and understand your obligations as an employer, paying tax and national insurance.
