I'm writing a story based around a magical academy, does it sound too Harry Potter-y?
Judging by the information you included, I would say that (even if it bears some resemblance to Harry Potter) your world is unique to your own style. You said it yourself, too, houses are common in English schools. Not to mention the fact that schools of magic are a common theme in fiction itself.
Take "Little Witch Academia", for example. It's a magic school, there's witches and quills and all that, but the story is unique enough to be its own thing. As long as you put your own ideas into the story, it will be unique despite whatever it might remind people of. And even if it does remind people of Harry Potter, it could work to your advantage. If a scene is whimsical, it might bring back that feeling of going to Hogwarts for the first time, except the feeling is new because your story is also new.
Someone once said "good artists borrow, great artists steal". No matter what, you're going to find inspiration in things you like, it just happens, but the fact that you've taken that inspiration to put into your own world is great! Hope this helps!
