The wording we hold for 10E012 · how the whole register is watched
This was filed with the regulator 5,991 days ago and the register carries no date for the letter to owners. At that distance the blank is far more likely to be a gap in the record than a letter never posted, so it is counted apart from the recent ones: every notice still without one.
