I live very near to this school. It is our closest secondary. My kids don’t go there - they are in the private sector.
The reason they are pushing out this advertising is that they are under subscribed. Not a problem the local private schools have.
The school has an awful reputation locally for pastoral problems. If you look up the names on recent mumsnet threads you will find comments along those lines from other posters. They got RI on an ofsted in the past few years (now regraded) for both pastoral and teaching issues. The nature of the admissions arrangements means a significant proportion of the kids have challenging home circumstances.
Most parents prefer the other secondary that is just outside the parkland. It is a huge school on an extremely cramped site but admissions are on a religious basis and pastoral care is much better. The selection by willingness to go to church for 4 years leads to a more involved parent group.
The stables are very nice, but represent a tiny part of the experience for some students. They are open to anyone - one of my children has ridden that horse!
It is ultimately a state school with lots of the challenges that brings though. And you pay for it.
I strongly disagree with the VAT but using an example such as this doesn’t build a case. It is very niche and there is lots of background to that situation that you can’t see from the advert or website.
