I'm a parent whose child joined The Gower School at reception stage. This is my honest personal opinion based on my direction experience only:
Positives: The best thing about the school is the community - parents and children are mostly extremely nice.
Lots of very good and caring teachers. Support staff are generally also very good.
Generally a good After School Club provision.
A small school which, in reception particularly, gives a gentle and free flowing introduction to Primary education.
Negatives: The fundamental structure of the school is problematic. The Headmistress/owner wields way too much power and is over officious.
The school is ridiculously time demanding of parents. With both parents working this grates very quickly and after a while begins to feel borderline neurotic. Expect to receive many messages per day over several channels. Expect to prepare and deliver snacks to feed your child's class and bring flowers to the classroom every term (stealth tax!).
The school oversteps what should be a clear boundary between education and parenting. The school is exceptionally prescriptive with mandatory parenting workshops about what you should and shouldn't be doing as a parent. This can feel overbearing and patronising.
Fees rise significantly year on year.
As has been pointed out over the years in this thread, there is still a high turnover of staff at the school. A very small minority of staff are poor. This lead us to experience several instances of substandard and wholly inadequate pastoral care at the school. When you do experience safeguarding issues, I found there not to be a culture of taking on board constructive criticism and the school being willing to learn from (sometimes very worrying) mistakes.
I often felt that the focus on the basics of Maths and English was overlooked with far too much time spent on dress up days, engagement in pr awards for the school, endless charity events, rehearsals for assemblies, performances and plays. These things are all great but should not be secondary to basic education. This increasingly felt like it was the case. In reception it's not such an issue but by Year 2, I had to pick up the slack by tutoring my child, which shouldn't really be the case when you're paying for the privilege of private education.
The final nail in the coffin for us was that in the end the safeguarding issues we experienced meant that these academic concerns were secondary.
Reception was very good. Year 1 was ok. Year 2 was unacceptably poor.
We left after Year 2.
If I had my time over again, I would categorically choose another school.
