I wasn't known to social services until I applied for SA and requested home tutor! Some LA's seem to use this to force return to education, which is why I then had to provide HE to try and get SS off my back. I never actually had to HE, as after I wrote to LA etc saying this was the only option left for ds, they backed down and ds was signed off on medical grounds and home tutor was provided.
You could write and ask for them to provide a home tutor under the Education Act (section 19)
"Section 19 Education Act 1996
Exceptional Provision of education in PRU or elsewhere:
Each local education authority shall make arrangements for the provision of suitable education at school or otherwise than at school for those children of compulsory school age who, by reason of illness, exclusion from school or otherwise, may not for any period receive suitable education unless such arrangements are made for them.
In this section “suitable education”, in relation to a child or young person, means efficient education suitable to his age, ability and aptitude and to any special educational needs he may have"
Make it clear that you are requesting home tuition. Previously my request for home tuition while ds was signed off, was misinterpreted (on purpose) as me wanting to HE, even though I quoted section 19 at them!
After GP signed ds off and requested home tuition, LA reported me to social services. So be carefully of their dirty tricks.
