My son had five happy years there until 2017 despite a wide range of problems anchored around the very odd management structure, and quirky rules reflecting the dual role of proprietor/head. Many parents complained and got nowhere.
The Hall produced well-rounded polite children with good values I have to say.
I believe tge aforementioned issues are all behind the school now as a new owning company and management are in place from this year so that being the case, it’s worth taking a look at it.
I can give you a contact of a parent there now to give you a more up to date picture.
