If letters went out, I missed it! In fact, the snotty letter I got from the council, advising me that I need to remove my ariels and gutter scurf, did not reference this new fangled letter scheme. It's official, though! In a database. Every time I order anything online I get a choice of A-H. I believe the ground floor flats are council property. Probably polish pikeys living there. I dare not mess with their frontage!
