Unless to 2, 5 (parts), 6 (possibly), 8 (back in the day), 9 (they say, if you aren't white, or just have a horror of endless suburbia and white vans), 15 (parts), 17 or 18. And 25 is quite similar.

But - if you are bothered about such things and prepared to make inferences from postcode alone - thenutfield's trajectory is not consistently upwardly mobile, either - like 3 to 13 and 21 back to 13...
