Ah, gotcha... and I know the song.
(just been taking a few hits on here of late so I've gotten a bit bleurgh)
Yeah, possibly I've been a little unllucky, it's just that I asked 5 people to quote for me from various sources and all have come up with different solutions, different ways of doing things, different 'rules' of what's 'allowed' (!!), and different ideas,... and very different prices, so it's unbelievably tricky for the layperson to try to work out what's actually needed and how much one should actually be paying when people in the trade are doing it every single day so know the worth & value of most things, boiler-wise.
If it was all along the same way, you could judge things on price, professionalism, apparent knowledge, etc. but it's such a wide playing field it's a nightmare when you're not up to speed. I appreciate all the people on here who have been giving their honest opinions though, I'm very much more clued up as to what I need and which plumbers seem to be on the money and which are wide of the mark.
Well done fellas. :willy_nilly:
(To be fair, I don't think the guys were 'bad' plumbers or anything like that, it was just such a variation that some outshone others, that's all. That's life!)
