It depends while you are overcrowded does not mean they will move you .as priority
For example I ended up in 3 bed house which is wheelchair adapted (which I do need hence why I took it
even though by their rules I was overcrowded (at that point I should by their rules be in 4bed
5 years on still here and kids older so in theory I need a 5 bed which they admit but it's only advisory not law
I have two over 16
Daughter 14
Son 11 who has sn
Plus me i sleep in lounge but as mine is open plan they don't count it as bedroom
