英语上门私教怎么说

"Private English tutoring at home" or "In-home private English tutoring" are both ways you could describe private English language lessons that take place at the student's home.
Alternatively, you could simply say "Private English lessons at home" or "Private English tutoring in-home."
It's also common to use the phrase "one-on-one" or "individual" to describe private tutoring, as opposed to group lessons. For example, you could say "I offer one-on-one private English tutoring at home."
