We are planning a move to Winchester, but are unsure whether to move this year to be in place for October 2013 secondary applications ( daughter currently in year 5 so we'll be applying for September 2014 entry), or move in summer 2014 and cross our fingers that we get a place for her. Our plan in either instance would be to rent initially, while we look for our forever home in Winchester and sell our London house, so in theory we could find a place close to Westgate, Kings School or wherever. I probably slightly favour Westgate from my limited knowledge, partly because I like the look of the associated primary schools (my son is currently in year 2).
I know it probably makes more sense to move sooner rather than later, but my daughter (who is pretty resistant to the idea of moving) would so love to finish year 6 where she is now, so I am (weakly) wondering whether it would be possible to do that, and then hope to get in to a Winchester secondary on the waiting list. My son is currently in year 2, so we'd be doing an in-year application for him whatever happens, plus he is VERY easy going and keen on moving nearer to green open spaces.
