What is the legal age when I can leave my children home alone?
There is no legal age when a child can be left home alone and it is down to the parent/guardian/carer to make that decision.
Common sense would suggest that the child would have to be of an age where they could look after themselves and that it would not be appropriate to leave a young child for long periods of time or during the night.
Bear in mind that endangering a child by leaving them unattended is an offence. NSPCC guidelines recommend most children under 13 should not be left unsupervised for long.
