I am working as a weekend nanny for a family who pay me with tax credits. The family also use a nursery during the week. When it's school holidays I work extra hours but this easter she has decided to use her friend for childcare and I think she will using the tax credits to pay her. Basically what I am asking is can she pay her friend with tax credits (I thought they had to be ofsted registered) and how do I make sure she isn't using my registration number?
