I can see why angle iron would be used so as not to disturb the inner
skin, but it seems quite a long span, and that some sort of U-shaped
construction on its side that would allow two or three courses of
bricks to be built within the U would be required. How is the weight
of the roof factored in?
What's supporting the inner leaf? Where does the roof load go (often inner
leaf, but do you know for sure?)
Personally, over that distance, I'd consider a steel box lintel of some
sort.

Is there a table or calculator online that deals with this? And
should it be BCO inspected?
Thanks.
I think you need to rectify this, and get the BCO involved - but watch this
space for more comments.
I'm even less of a structural engineer but....
When I was whinging to an architect about building a wall over a
concrete floor with uncertain foundations, he suggested using 3 courses
including expanded metal to form a beam. (blockwork).
Is it possible that the clearly inadequate angle iron is only intended
to support the first course?
