Well, it isn't because it cant be defined - bi
Big brother takes little brother to park for a kick about
Little brother's friend asks to join in
This becomes a regular after school hobby in local park
Another friend joins
Friend 2s mum buys big brother an icecream as a thank you
Friend 1s Mum buys him fish and chips one night
Friend 1's mum then one day hasn't got time to buy the chips, so gives big brother the money to buy his own
At what point did this become a paid club that big brother needed a DBS check for? Does it make a difference if he is 11 years old, 15, 17or 20?
Does it become formal once there is a whatsapp group? or when there are 4 little ones joining in? or when big brother accepts the ices cream? Or when big brother's best friend asks if he can help too and share the chips??
So no, not a legal requirement for big brother to have DBS check
