Stratford (Newham) - preps?

[Nevista]

Does anyone live in that area of East London and use a good prep or are there any really? A cursory search didn't lead to much.

Don’t know them but may be a start

Try googling redbridge preps. Next door borough, a bit posher.

Gatehouse school, near mile end / victoria park would be the common choice in that area - have not had a kid there myself (slightly too far), but have known people with kids there and they (and the kids) were happy with it.
There are more options if you go slightly out of town on the central line towards snaresbrook / woodford.
