I need to fit a hob extractor vent but I can't get it more than 200mm
away from the boiler terminal. To get the 300mm minimum distance I want
to run the extractor duct a short way up the outside of the wall but I
haven't found anywhere that sells suitable brown rectangular plastic
ducting ... any suggestions?

Convert to round pipe before you come through the wall - much more
choice then.

I was hoping to keep it tight to the wall and not too visually
disturbing. I only need to go up by 100mm. Doesn't round mean stainless,
and ping ping noises when it rains?

Try bes.co.uk - they have lots of flat ducting.

If no brown, consider painting it with a suitable uPVC paint - maybe
from a car paintshop, something like Vinylkote might do it.

You should be able to use upvc eg terracotta if it is against brickwork

And round pipe has a lower flow resistance than the same size of
rectangular pipe IIRC.
