In reply to alasdair19:
Lived in Bradwell many years ago, but prior to having kids.
You will meet & integrate with the other residents far quicker with having children of local school age, although, sure you still have the choice of sending them to a alternative village school.
Quite common to find yourself driving more for the kids to attend after school/weekend activities as they become older, this is common to living in any village to be honest.
I enjoyed living there as quickly realised that Sheffield is only 20 minutes away but obviously you have the advantages of village life, the crux is how dependant you are on city living.
My initial thoughts & concerns on moving to Bradwell from Sheffield were probably similar to yours but really enjoyed living there once I realised that it was really an outlying suburb of Sheffield!
