That's beech then.
Isn't it Beech? Looks a whole lot like Beech to me. Leaves look right and the nuts look like Beech nuts.
Kind of rounded looking leaves though;

Looks like beech to me....does it have little brown withered bits under some of the leaves where they come out of the branches ? That's the remains of the overwintering buds.
Kind of rounded looking leaves though; it can be hard to get everything in the photo for ID.
