Childminders, what and how do you charge?

[JeanGenie23]

Good evening all, I haven't put my fees up in years, and I am vaguely aware of how cheap I am in comparison to others. I don't want to under value myself, I equally don't want to be over charging. If you wouldn't mind telling me of course, it would be helpful to see what others charge.
I am based in north east London, I am open mom-fri 8am-6pm and serve all organic homemade meals, and snacks. I currently charge £5.95p/h. I was toying with charging £6.20p/h, but is that too much? (Far lower than local nursery and I do accept vouchers payments and early years funding)
Any advice welcome

A nursery will also be VAT registered, will be able to actually use government initiatives and grants and will also be able to take advantage of daytime training without having to close and lose income.

You say that nurseries have all these extra staff costs. Who do you think does all that additional work in a childminder setting? Should it be done for free?
