I think that the above will be helpful to you. However, I have not used either of the linked to insurance providers so cannot speak from personal experience. Always check the level of cover and terms of cover carefully and think about possible scenarios and whether the insurance will apply in those cases. Buying a policy purely on price can mean you end up with something that doesn't cover you in those cases where you need (and are expecting) to be covered.

Hello, can anyone help me with the following:
- I need to get an insurance as an employer to a nanny; I had one previously as part of a home insurance, however at the moment we don't have a home insurance as we rent our place and we have no need for a contents home insurance. Does anyone know of how to get insured as employer specifically?
- Also I would like to get a liability insurance for damages that would be caused by my children; does such thing exist here in the UK? I have looked online but can't really find anything helpful...
Thank you for your help!
