Not if the installer routed the condensate drain indoors.
I had that problem. However, the guy who came back to check it out was the guy who'd originally come in and quoted me for the work (local company I'd used for servicing my existing boiler at that point). He went back and had serious words with the young guys who'd installed it the year before, as they'd not routed the condensate pipe indoors as he'd factored into the quote price.
He came back himself and over two visits replumbed it to run across my hall, into the bathroom, in under the shower and out to the drainage pipe beneath my bath. Took him about 6hrs in total (lots of drilling through thick, stone walls and cutting pipework to run unobtrusively around the hall wall), and I wasn't charged. He did it so well that all I had to do was put the tiles back on the front of the shower base and cut one to fit around the pipe. No other mess at all.
That's what I call service.
For those in the Edinburgh area, the company is 'Contract Heating'. Been using them for almost 12 years and they're excellent.
(Additionally, they were over a grand cheaper than the price I was quoted by British Gas - and BG wanted to rip up my hall and bathroom flooring to route the condensate pipework, which would have set me back another few grand having that all replaced).
