Buying, selling or living near a substation a large National Grid substation, you would need to be within metres or maybe tens of metres of the perimeter to get an elevated field. It would be rare to live that close in a rural setting but could happen in an urban setting. But you would probably be getting a higher field from the lines or cables entering the substation.
