"Yes, DS does have a funded place. Does this make any difference?"
Yes, it would make a difference in our LA.
You would need to contact your LA to see if makes a difference in yours.
Ask them what their policy on moving between settings is.
Here, straightforward 'late claims' aren't a problem (ie if your child hasn't been in attendance anywhere else) and children would be funded at the new setting. However, moving between settings is a different matter and is only granted if 'Exceptional Circumstances' apply.
If this is the case, then you would need to state why you are moving your child.
If you feel the nursery are being negligent in any way, you have a duty to inform Ofsted.
"Notice period...I have no idea, shit!"
You would also need to find this out.
It's usually part of your contract when you sign up and if you leave without giving a notice period, in most cases (where there aren't other allegations) you would be liable to pay back any monies.
