Hi, this edit has gone a little wrong.

I assume it is an automated armchair edit as you didn't look at the edit history or notes?
If you had you would have seen that https://www.openstreetmap.org/node/11979023547 has been added in error as https://www.openstreetmap.org/way/204828073/history and https://www.openstreetmap.org/note/4229717would have told you. 

FHRS is a useful source of postcode data for businesses already in OSM but it should not be seen as a source from which to add new objects to OSM.

Cheers Phil
