Glad to be of service. I hope you find a good childminder for your little one.
You might also try childcare.co.uk for contacts.
Your local authority will keep a database of registered childcare providers, as a requirement of The Children’s Act. I think Penge comes under LB of Bromley, in which case you’ll find the search tool at Bromley.gov.uk/childcare.
By happy coincidence, the headquarters of PACEY (formerly the National Childminders Association) is also in Bromley. They might be able to advise; their number is 0300 003 0005.
