There are 6 chargers in blackburn and 6 in Leeds.I am guessing you are from the south of England and seldom travel north of Birmingham?
Draw a line from Preston to Leeds and tell me which of the four, yes 4, Ionity chargers situated north of that line could best be used by the rest of the UK to the north of that line! I would drive south past two SC’s to get to the first Ionity.
