Yeah the floor there is back to front but how are the boards laid underneath probably going by your luck it’ll be the opposite direction so it’s hard to guess until you lift it and as you said if the floor comes up easy your onto a winner if it’s glued and breaks your fucked.
Its not the distruption its what way the boards go and lifting that floor and the one under won't be easy without fucking the engineered.
The skirting will be fine as will be the floor underneath but the engineered flooring is an issue.
I'm also guessing you cant crawl under there or can you as thats the only way to do it without disruption to the floor.
