Thank you @RedOrangeYellowGreenBlueIndigo that has really helped me understand what we should be thinking about.
A bit of Googling has shown the school still operates with a catchment area and if we moved now we would be priority 2, after looked after children, as we would be living in the catchment area (which is huge! It spans 10 miles in each direction from the school - no more fighting with 0.01 of a mile). Also, it would be the closest school to us at 2.5 miles away. The next one wouldn’t be for 12 miles.
Despite this, the school is undersubscribed, not because its awful, it’s actually been outstanding in its last 3 inspections, had a write up from the good schools guide and is very highly regarded by the locals (DH actually went there and I’m convinced he’s a genius, which he credits to the school), but because there just aren’t enough children to fill the places. 200 places available and in the last 3 years has taken (excluding 2021) 184, 168 and 177. So I think it wouldn’t matter where we applied from, we would get a place. So if we can’t get jobs quickly and sell our current house quickly then we can sleep safe knowing we will get a place.
@Retrievemysanity I will ring the council and explain. Thanks for that suggestion, for some reason it didn’t occur to me to do the most obvious thing.
For all who have said that kids settle well into year 6, and make friends before secondary, @TeenMinusTestsand and @SillyBub, I think we need to explore this more. We will certainly be doing that as I think that’s an important point you both make. But looking at the info available on the council website, our local primary might be full - so we shall see what they say and where we would be able to send DS (and DD for that matter). DS (and DD) both know the area well because of many many visits, they have spent whole Easter holidays and half terms up there in the past, and they do know a few children from the village, just not as many as if they were at school because they aren’t necessarily in the same year. It would be nice if they knew some in their own year groups.
