I am starting a nanny share and the share will be in the other family's house. They would only use our house infrequently, e.g. if the other child was ill with something v infectious and staying at home with mum. I did recommended the other mum check if her home insurance covers a Nanny, but as the Nanny is a close member of their family I don't think they are expecting any legal disagreements, so I am not sure whether she has checked.
Do I need employers insurance for employing a Nanny if she is not working in my house?
Do I need insurance if she works in my home infrequently e.g. if the other family is ill?
If the other family don't have insurance and there is an incident at their home, am I partly liable? E.g. should I push the point that they should check they are insured?
We don't currently have house insurance, so we would need to get it especially to cover the Nanny if we need it, which is why we are asking.
If we do need it, can anyone recommend any policies suited to renters? We rent furnished flats, I struggled to find any policies that were suited to this situation.
