IYO who was more responsible for this communications cock-up?

[TheOneWithTheNicestSmile]

Old wooden French windows being replaced with uPVC (all windows in house also being replaced so quite a big job)

Each door of old Fw had 3 panes of glass & there was a top opening window above

New Fw have one long pane in each door plus a small plastic panel below, in one of which a cat flap will be installed.

I assumed that given previous top opener, new doors would also have top opener above.

Window fitter assumed that because industry standard is apparently to have a fixed fanlight above Fw, that would be what was required.

Neither of us asked the key question...

What would you expect & how would you deal with the fallout?

Both parties. You should have specified it was wht you wanted and contractor should have specified why he was fitting before having the doors made.

what he was fitting. Not why. He knows why

Oh good, that's what I said (though there was an awful long sticky moment) - we both failed to communicate so we should halve the extra cost of having them redone

(Though I have to trust him to be straight about the true cost of having them redone...)

Yes i was thinking halving the cost would be fair.
