Look at this, it is ILLEGAL to look after children any age even in your own home for payment unless you are registered !

You can look after a child or two but you CAN NOT be paid it has to be free of any charge. The regulations on this are very strict now and quite rightly .
You need to be registered, CRB checked, insured and the house or place you look after them has to be fully checked. Anyone who lives in the house where the children are minded has to be CRB checked as well even if they are not there at the same time as the children. For example your husband may not get home until 6.30pm and the child care finishes at 4 pm but he still has to have an enhanced CRB check !
Your statement that 'you know you don't have to be registered for children over 8' is is just plain WRONG ! you have to be registered for any child from birth to 18 years old.
