Hi there,
First post, but hopefully something that may help. We are also in your situation We attended the Independent Schools show in London last weekend. A friend of mine told me to go, and all the schools you mentioned were there.
From the outset I had a clear criteria in mind. 1. Must have lots of boarders at the weekends- none of this everyone goes home on Saturday! 2. Good scholarship results and varied selection of feeder schools. 3. Caring staff and strong pastoral care.
What was really interesting was some school stands were extremely 'quiet', but the one which had the most interest was Windlesham House. By chance, my hb met some of his work colleagues at the stand and they were raving about the school in particular the friendly atmosphere.
We narrowed down our choice to 4 schools and visited them this week. Ludgrove was not for us..just not the right feel.
Dragon..lovely school..but stuck in the middle of the city.
Port Regis...amazing facilities, but few weekend boarders.
Windlesham House...loved it! All the reviews on here were very accurate. Lovely feel, lots of boarders at weekends, friendly staff and only 20 minutes from Gatwick Airport!
Booked both my sons in for two nights of trial boarding and they loved it and wanted to stay and not go back to their school in HK!
So there you have it, Windlesham House it is for us!
