I think the best thing you can do is follow the link provided by Wraith. it seems to be a good website with sound advice and has some good links as well.
The bottom line is that there is no specified age limit prescribed by law as to when you can leave a child at home alone or when someone can babysit (a child being under 18 years of age). Just check out the website, it says it as well as any professional could.
There is no legal age but NSPCC guidelines suggest no child should be left alone under the age of 12 and not left alone overnight until 16.
it all depends on your child, how mature they are, how able to cope in a crisis they are and how they feel about it.
