Excellent responses, thanks.

Any recommendations for a structural engineer in Cheshire/Staffordshire/Shropshire?

Don't be silly. Recommending a use of them is not the same as having
ever used them.

The oak -if oak they be, are purlins. The wall plate rests on the wall.
The joists pulling the rafters together will occur above or below the
purlins but the way the rafters bend with resultants will change.

Instead of tending to arc out they will tend to arc in. Getting good
photos before you do the job will not only get you more confidant help
but provide you with a record of stability over the years you remain
there.

Whatever you decide, there was something already wrong with the building
when you had to pull the ceiling down. I suspect a previous owner did
something non-U with the roof. Get lots of lights in there and a good
photographer.
