Since you are in the UK, my first thought would definitely be something like a Barbour Bedale. They are shorter than the more common Beaufort and don't have the game pocket in the back. You may, of course, think the UCT quotient is too high. But it doesn't really look costumey and does not look out-of-place even in central London, especially at the weekends. And it would certainly work with all of these jeans, "cords, chinos, desert boots, sneakers, boat shoes" except maybe boat shoes. But a field jacket wouldn't either, of course.
A modified safari jacket in heavy canvas, would probably look pretty good too, especially if you lose the epaulets and the upper outside pockets.
