I have two boys in Year 8 and Year 4 relocating from Asia to London next week. Year 8 boy had no option other than Hampton Court House School and we are just happy that he can go to school without moving for his senior and sixth form.
For year 4, we could send him to HCHS with his brother or choose to go to prep school in Kingston, Rokeby school.
He is very sporty and wish to enjoy all sorts of sports and extra curriuculars at school. I don't know how both schools are invest in for sports and extra currlculars but with one class in year 4, team sports wouldn't be possible.
I am also not sure what will be the traffic situation between the two schools, HCHS provides door pick-up so if the two boys can go together,
it would be super convenient for me but Rokeby I have to drive younger one to the school or nearest bus stop. They don't seem to run bus around Hampton or East Molesey.
