We’re hoping to move out of London in the nearish future. The lure of being mortgage-free and being closer to the countryside is getting ever stronger. However dd is partway through Y10 at an academically selective school - she’s currently on course to get 8s/9s across the board.
Both dh and dd are keen to move as soon as we can sell our house (not currently on the market) but I’ve said we have to wait until dd’s finished her GCSEs so we’d be looking at moving in time for her to start sixth form (there are several outstanding sixth forms in the area we’re considering).
Dh isn’t from the UK and doesn’t fully understand the English education system and doesn’t believe me when I say it’s a really bad time to move. Dd’s desperate to move as she doesn’t like being in a big city (loves being outside and spending as much time as possible at the stables) and she’s convinced she’d be fine 
I’m right here, aren’t I?
