I am hoping the MN hive mind can offer some advice here, because I'm running out of ideas...
A few years ago I moved into a flat in a converted Victorian house where the flats used to have numbers 1, 2, 3 etc. but then one flat got bought up by the neighbour and turned into a maisonette and the numbers got adjusted (just for context).
The address of my flat doesn't turn up on the standard drop down menu you get on most websites which ask you to input your address. (it doesn't turn up with either its original number or the new number). I've meant to sort this out for years because it's a bit of a pain entering the address manually and sometimes you don't have that option. But I'm not sure how.
Is there a central database of addresses where I need to update it? If so, where would that be? The Land Registry? The city council? Any advice would be very much appreciated!
