flaking and powder like paint

Hi I have flaking and dusty paint on walls around plug sockets and other patches at low points and some random areas around 1 metre up. I know there are lots of questions and answers but I would like a definitive answer (if poss) as it seems wall may need to be sealed properly with either pva OR mist coat. Any ideas? As some suggest PVA is a no no. Two separate firms, (one that originally painted it during my refurb then done it again when the problem arose and another set when the problem returned) have tried to correct the problem but each time this problem seems to come back. I am not sure what either firm did by the way. The wall is not damp and has hade a new damp proof course and this has been check and all is good. I would appreciate and feedback as it looks terrible. I have read on here that it could be some type of salt, does that seem plausible?Whichever solution can I just repair the areas and their surrounding areas or do I need to completely do whole wall? Any ideas greatly appreciated. Finally, how many coats would I use for best method and would more undercoats of either be best....I only ask as I really want to ensure this does not come back....well hopefully. thanks Darren
