yes alright you great ninny (said with the confidence of a woman who doesn't live in London and therefore won't need your professional help). ;-) What I mean is, acronyms are a bugger for reading when they pop up in prose. Even when they are defined at the beginning of a piece, it means that readers - particularly new readers - have to keep checking what it means. And an acronym which is everyday to you, and becoming familiar to your regular readers, is still going to be pretty alien to a first-time reader. Not that you should cut them out completely, but beware...
