Well third time lucky, deleted my first two posts before I posted them, beer and politics just don't mix.
Firstly, Electrofy, if you could just clarify are you a plumber/heating engineer? If not what do you do, if you don't mind sharing?
Secondly, could you expand on 'administration'. Mine at the moment consists of estimating, invoicing and bookkeeping, all of which I do by myself as a sole trader.
Thirdly, used many a QMS, dating back to my apprentice days right through to my 'time out' period when I was working for a pharmeceutical company which was quality assured to death. Couldn't take a dump without following procedure. All well and good for injectables, batch traceability and trying your damnedest not to kill people. But taking a product like solar thermal, installing it correctly having been trained and assessed to do so using qms is complete overkill.
Fourthly, setting aside the part that I could go out and 'buy' a qms and 'adopt' as you state (something that has previously been stated by easy mcs, site sponsor, is not the way to do it), is that really something I would want to do when we are still awaiting just what the RHI will do for the domestic market come 2012.
To summarise, it appears, or as you say it works for you, good. The general concensus is that it will drive unnecessary cost towards the 'one man band brigade' and ultimately onto the customer. As the system currently stands I cannot see it working for me, doesn't mean I won't install renewables though, just that I'll do it whatever way I can to avoid MCS involvement and the costs involved with it.
Rant over.
