Childcare element of tax credits

[Abidewithme3]

Advice please,

Are working tax credits tied to claiming child care tax credits? So if my child went to granny while I worked could I still claim working tax credits or do I have to use Ofsted registered child care to claim?

Essentially is it all one claim or are they seperate?

Childcare tax credits are to pay for childcare - registered childcare.
Working tax credits you can recieve (if eligible) wether or not you use childcare or even if you don't have children.

Thank you very much Etak that's exactly the info I needed.
