Thanks for all the advice guys. Very helpful.
I have so many things to sort out before it can happen, and this seems to be a big one!
Just for info, my search criteria goes like this. Drop a pin in Silverstone (work), then search a 30 mile radius from there. On the ouskirts of the rule, and where I've been looking is Chipping Norton (NE Cotswolds). The wife and I have a bit of a connection to the place.
Other than that (as pointed out), it'll come down to schools to base ourselves near.
