OP - you haven’t said how old you children are?
Re- secondary schools. The independent secondary schools in SW / West London are fiercely competitive to gain a place. You need to be in the top 2-3% nationally (academically) to even have a chance. In Ealing, you would be within striking distance of the Hammersmith area schools eg -
St Paul’s Boys (Barnes)
Latymer Upper ( co-ed Ravenscourt Park)
St Paul’s Girls (Brook Green)
Godolphin and Latymer (girls Hammersmith)
The odds of a place at 11 plus for any if the above are 1 in 10 by competitive exam and interview processes. These are all in the top 5-10 schools nationally.
There are also frequent coaches from Ealing / Chiswick way to Hampton School (boys) and LEH (Girls), But again these schools would be roughly in the top ten nationally and equally competitive.
Schools for the more “rounded” student would be Kew House (actually in Chiswick), but even that’s competitive. There not much else really - be warned, getting into an independent secondary school in this area is a total nightmare as the schools are all the most academic in the UK and there not much choice for the more avarage or even above average child.
No grammar schools except for the two Tifin schools, but they’re in Kingston so quite a trek.
There are loads of preps focused and experienced in getting DC places at above schools. You won’t have a problem there.
There nothing wrong with Ealing, but like anywhere in West London, there are beautiful streets of multi-million pound homes, often quite near not so prestigious areas. Ealing is a large place though. Agree that you could also look at Chiswick as it’s on the doorstep.
If you grew up in Maida Vale you would know that there are dodgy areas right on the doorstep there too? Also, not sure why you’re writing it as maidavale?
