I use ABM Sky London SD custom bouquet (with HD swap). BBC1 London HD is at position 101 and is as Sky/Freesat intended - the regional HD channel. The Freesat ABM bouquet also has BBC1 London HD at position 101 and has "channel removed" at position 106. No BBC1 SD regional service on Freesat. ABM seems ok to me, bot on Freesat and Sky - I don't worry about the BBC1 SD service which is going to disappear in any case.
