As someone mentioned earlier, I'd have a face to face meeting and iron out the details. You go with all your conditions written down and see what he has to say. Nothing annoys me more than being on a job and having to go off and get bits. I think it might be hard work but i'd have a go, if he can agree to enough of what you want to make it worthwhile.
If he is being that fussy over a couple of lengths of pipe then he isn't going to find it easy to find someone else to take on the work.
I admit I'd be tempted to get in with him if he does have that much work going.
Interested to see what happens but I could easily see village idiot passing it up if it will be too much stress. I swear some people think it's possible to do a boiler swap just by looking at the boiler on the wall in a certain way.
