After receiving some incredibly high quotes for replacing the boiler,
in a different position, and having established ftom the FAQ, and from
the H&S website that it isn't illegal, I'm going to fit my own new
combi boiler. I'm sure I'd have no trouble fitting an Ariston Micro
(Non-condensing).
I haven't examined others, but imagine most standard combis such as
Bosch Worcester are similar to fit. True?

Is a condensing boiler significantly more tricky to fit? If so, how?
Is there additional specialist equipment that I'd need?
How big & intrusive is the plume from a condensing boiler? I've never
seen one in action.
I will fit it as close as allowed to eaves level (first floor), so that
should help keep the plume at bay.

How do you propose to get BCO approval?
