Charges vary across the country - in london & other city centres it can be �5 or more per hour, in more rural areas you'll find charges nearer �3. Also some Childminders offer lower rates for full time places or full days but have higher rates you only want a few hours per day.
Many Registered Childminders will provide meals, this may be included in a daily fee but may be charged separately. Because of unknown allergies etc, Childminders may ask that weaning/first meals are given at home. Changes in the law mean that all Registered Childminders will have or be about to register as a food business with their Local Authority.
As well as meals, when comparing fees you should find out about costs for absence, holidays (yours & theirs), and check whether fees include snacks, outings, toddler group, nappies etc.
You can get details of local Registered Childminders from www.childcarelinks.gov.uk. Registered Childminders are now required to display their Registration Certificate - be sure to read this AND their full Ofsted inspection report to check they are registered with Ofsted.
