in the south-east of England

means within the south-east region, surrounded by the border of the south-east region.

on the east coast

generally means next to the water, a coast doesn't really have an area, otherwise you might say

in the costal region

  • I would say that on is used to mean at or near a boundary. So, for example, on the east coast refers to the boundary between the ocean and the eastern shore, while on the Peruvian border would refer to the border running between Peru and some adjacent nation, as in: Huaquillas (Ecuador) is a city on the Peruvian border.
