Have you heard about Open Family Services?
www.openfamilyservices.org.uk
No me neither, yet they have been going for 7 months now. I don't know how many local authorities are uploading data but back in early October OFS reported that they had over 60,000 records so that's a start.
So have a look and if you are a childcare provider and you are not listed, contact your local Family Information Service and request that they upload your data.
