Engineer, post #10 refers to the period of time between inspections - NOT whether they should be undertaken or not. It was answered by Andy, most amiably in post #12 and has no bearing on the initial question. Why so picky? Your abject consternation is only belittled by everyone else's objective conversation.
Of course it has pertinent implications there's a big difference between rented accommodation (which is how the original thread read) and privately owned property, eg access to inspect being a major aspect. As for post #13, what does it matter whether the place is managed by a residents committee, a property factor or a coven of witches. It has no bearing on the initial question. I wanted some advice and, other than your own responses - which I sense are not based on any experience of 'workaday' sparking in the private sector - I was offered plenty of good advice from the cordial responses I received from others, and from which I have determined my approach to the matter. I think that's how it should be. I took nothing from your posts, other than a sense of your angst. I repeat, save yourself the bother of manifesting that angst in typing out unhelpful, pointless words - PLEASE don't respond to any of my posts.
You obviously have no experience of residents committees then! lol!!
You got the best advise you could have received chum, trying to price a job that you have no idea of the scope of works involved in just plain crazy..... There could also be 2 or 3 different flat layouts so you would need to know if the same amount of circuits are common or not to all
Oh, and i can't see any management company, that manages properties of this size not having a scobby doo about the scope of works they are putting out to tender!!
And as for;
"I think you'll find that most here are fed-up with OP's drip feeding relevant information pertinent to the advise being sought as they go along. Threads end up twice as long, but more than anything else it's bloody annoying!!"
I think you'll find on re-reading the thread that nobody else - let alone most - expressed being fed-up. Just you.
