Heya, I think there’s some confusion here.

There are two ways to tag UK addresses in OSM. The most common way is to put the settlement (Casterton) in addr:city and the street (Fern Croft) in addr:street.

Another way is to add the post town, although aiui Royal Mail doesn’t really use these since 2004, and they are irrelevant to most people. There is, however, an accepted tagging scheme for them, which would be addr:city=Carnforth addr:suburb=Casterton addr:street=Fern Croft.

See https://wiki.openstreetmap.org/wiki/Addresses_in_the_United_Kingdom

There is a third tagging scheme for addresses which _don’t_ have a street name (which applies to many of the addresses in Casterton). I had to brush up on this one, hence me incorrectly undoing some of your addressing changes along those lines a few weeks ago. Sorry about that. If an address doesn’t have a street name, use addr:place=Casterton, and no addr:street or addr:city tags.

Putting a comma in addr:street is not one of the valid tagging schemes.

I hope that makes sense. I realise it’s a lot to read (sorry!) but addresses are inherently complex, and the tagging scheme on OSM needs to work globally.

Happy to discuss this further if you’ve got any questions :)
