Career change?

From Yorkshire; I’m currently working as a tradesman I’m in my early 20s and make ~30K which is good money for my age, but the trade itself is awful, im always away from home for weeks on end, the work is always dusty and unhealthy, I simply don’t like it anymore. I wanna change to something that’s still hands on but won’t take a serious pay cut. Does anybody have any advice on what route to take. I’d love to be a mechanical engineer or the likes but it means working from the ground up again
