Ideas for places to move within an hour of central London

[locationideas]

We want to move house in the next year or so but not sure where. I thought MN is bound to have some good ideas!

Our criteria are:

1. Excellent school options. This is our main reason for moving so definitely our top focus. Our current area has good primaries but mediocre secondaries. We can't afford private, wouldn't be against a grammar area but only if there are also good non-selective options. Single sex would be fine, we have two girls (eldest aged 7).
2. We need to be able to commute to Waterloo, Charing Cross or Victoria in 1 hour 15 (door to door, not time spent on train).
3. We would like a nice, safe, family-friendly area. It would be good to have a decent (pretty?) high street but we really don't need anything too exciting, we don't mind somewhere a bit dull (we are getting old and boring )
4. Our budget is up to 800k for a four bed house.
5. We would prefer somewhere on the tube but it's not essential.

Any suggestions wise mumsnetters?

What about somewhere in the catchment of Waldegrave school?

Bromley has good schools, easy access to Victoria and Charing Cross by train. Beckenham and West Wickham have good high streets with Bromley having a big shopping centre. It's generally a family friendly borough and greener than inner London.
