In a nutshell:
DS is in Y4. DH recently got a new job which involves a 1.5hr commute, the reasons for the job change are complex but suffice to say it's a long term change. So we are considering our options; we are thinking of moving nearer to the new job.
There is no big rush; we will have to sell and buy so it will be a slow process anyway but I'm trying to work out what's going to be easiest on DS. As I understand we would need to have completed on our sale and purchase by the end of October when he is Y6 (so October '23) in order to apply for secondaries in the new area. But 1.5hrs is way too long for a school run even for a few months so then does it make more sense to move before he starts Y6 so he can do Y6 with some kids who will likely be going to the same secondary? What about moving part way through Y5 - better to have more time to find friends and settle in or better to move at the end of a school year?
Obviously I'm just thinking aloud atm, lots to think about. If it's relevant DS is popular enough and makes friends readily. He is fairly academic (on track for grammar in the current area though the new area is non-grammar which we prefer). He enjoys outdoor sports but has no special talent. Don't know if his personality affects whether it's best to move sooner or later?
