Try Looking at Bracknell/Crowthorne/Wokingham
Rail is waterloo/Paddington or most others via Reading line
Motorways are m3,m4 and Heathrow is 25mins by car.

I lived in Martins Heron for about 12 years.. now living in Guildford, commuting to/from london.
I can give the low down on Bracknell etc.
1. train is slow line and every 30 minutes - 1h into waterloo
2. secondary schools aren't great and the the largest (and the best at "average" rating) has a catchment area spanning up to ascot (including the nice to be areas - unless you go private).
3. you could look at a martin's heron, ascot, sunning dale etc..
4. Bracknell town centre = dump. Reading is 20 mins by car.. has Oracle shopping centre etc.. okish..
5. Royal Ascot week.. a very, um, "refined" racing even.. reality is it's all traffic jams, drunken idiots getting chaperoned by the heavy police presence on/off the train.
6. Bracknell - waterloo season ticket ~1000 for 3 months. not including tube for the 1 hour trip.. seats/standing is 50/50 chance..
An alternative is Guildford and the surrounding area. 38 minutes into waterloo (there's fast and slow trains.. literally every 15mins), main train lines but more likely you'll run/brompton for the tain into w/loo.. A3 goes tight through it.
I'm in Burpham, reasonable area (steer clear of Bushy Hill in Merrow).. but there's lots of areas around. Burpham catchment area is for both primary and secondary schools that are graded excellent.
Guildford town centre rocks. It may appear smaller but lots of great shops and bars etc.
Now the bad bit.. train fare is 937 for 3 month season ticket.. not including tube .. but's 38 minutes.. seat/standing is 10/90.. I normally take my own travel seat
So far - from experience Guildford >> Bracknell/ascot area by a country mile.
Oh.. I used to work in Basingstoke - Chinham Gate.. they don't call it Basinggrad for nothing..
