In England if your child attends school, then you will need to go through a deregistration process in order to remove them and educate them at home.
This is quite straightforward and involves writing a letter to the Headteacher of the school.
Here is a suggested deregistration letter that can be used:
Sample deregistration letter
You do not need to get permission from the school or Local Authority to home educate, you simply need to inform the school of your decision and the school is then required to inform the Local authority that they have removed your child’s name from the register. You do not need to inform the Local Authority yourself.
Special educational needs children
For Special Educational Needs Children (SEN) not in special schools then the process for deregistration is the same as above. Unless the Statement specifies provision at home to be made by the LA, the statement becomes a legally unenforceable document. The LA will no longer have a statutory duty to arrange the provision specified in the statement and nor will the parents.
The LA are still under a duty to review the statement at least annually, until such time as they cease to maintain it. Where a child is established in Elective Home Education, it is reasonable for the LA to conclude that it is no longer necessary for them to make provision or to continue to maintain the statement. Parents who no longer seek provision from the LA could write to the LA asking them to cease to maintain the statement, as it is no longer appropriate.
For Special Educational Needs Children (SEN) in special schools the parents need to seek Local Authority consent to home educate.
Here is a suggested letter that could be used for this purpose from Education Otherwise:
