10 Childcare There's great potential to earn extra money from looking after kids, but you'll need to adore children (not just your own), have boundless energy and patience and in many cases must satisfy Ofsted criteria.

Any adult who looks after another person's child for more than two hours on any one day in a location other than the child's home (so excluding most babysitters and nannies) needs to register with Ofsted – it's not a particularly complicated process but does include medical, criminal and domestic safety checks. Nannies can look after the children of up to two sets of parents, in one of their home environments, without being Ofsted-registered.

Failing to meet the criteria can land you in court, so check here for the full list of Ofsted restrictions.
