becoming a childminder, what costs involved?

[Marbles]

Hi,
I currently work in a local pre school and am qualified to level 3. I am very interested in becoming a childminder.

I understand I need to go to the introductory/briefing on childminding then go down the route of the CHiP 6 session course and 12 hour paediatric first aid course. I can't find any reference to the cost of the childminding course except a £25 deposit. I need to plan my finances

Does it differ depending on region or is it across the board?

Many thanks in advance
