Beware banks. I've just had a letter saying mine are making changes. Too much to read it all and digest it, I can't do much about it anyway, but one of the things that stuck out was that unlike present where money from personal cheques is available immediately (or if a miracle happens and you get interest it will start accumulating it immediately) it will now take 2 to 4 days whilst it is apparently in limbo.
Cheques have always had a clearing period, OG. I remember when it could take 10 days, so the new system of 2-4 days is much better.
I have never known cheques clear immediately
