Whilst looking up the Childcare Exemptions Order 2008, I found Childcare Exemptions (Amendment) Order 2010 which is a result of the two police women's case.
The amendment is:
(2) In Article 3, after sub-paragraph (c) insert the following?
?(d)for?
(i)i)a child or children in the course of a friendship with the parents of that child or children; and
(ii)the provision is not made in exchange for payment.?.
(3) In this Article ?payment? means a payment of money or money?s worth, but does not include the provision of goods or services.
So "for reward" is now being defined a bit by using the term "payment" and stating that it is "payment" is money or money's worth.
What do they mean by Money's Worth?
