As per the "Transfer to secondary school" booklet for 2019 entry, a CCA move in date of 10th Dec (proof to be given by that date) was considered to be on time application provided
- you had applied to your home borough on time i.e. by CAF deadline
- you have named Redbridge school in your application by CAF deadline
In such cases, you had to provide the proof for change of address to Redbridge council by 10th Dec. Any change of address after that was considered to be late application.
https://www.redbridge.gov.uk/media/6698 ... inal-4.pdfPlease note - Guidelines change from year to year. Don't think a similar booklet for 2020 entry has been published by Redbridge council yet.
I would suggest you to drop a mail to Redbridge council to check.
