What's the need for 2 A+E's? I get the reason for wanting to be near 1, but why 2? I'm guessing based on your name it might be work related.

I could recommend Cheltenham, preferably around the Landsdowne area, you might struggle with £900k, but there is an A&E at Cheltenham, and 9 miles away in Gloucester..
Cheltenham, as it states, is "The gateway to the cotswolds".. and is nicely situated on the M5 with a good access link to the M4 (A419) so quite good when you want to travel anywhere..
Plus, it's got a fair whack of private schools, boarding and non-boarding..
