Looking at the picture I would say that the condense outlet on the boiler is probably below sink waste height so it's not feasible to run the condense that way. There is no way that a condense pump is a viable alternative as the condense needs to flow into the pump by gravity and there is never any room for a pump under that boiler.
The flue appears to be less than 300 from the window which is contravention of the manufacturers instructions and BS 5440 part 1.
The flue appears to be a baxi flue so it looks like the boiler is a Baxi Solo HE. Baxi state in their instructions that external condense routes greater than 3m should be in 32mm pipe to prevent freezing.
A possible in with the flat owner is to point out that, in case of a breakdown, Baxi will refuse to repair the appliance until the issue of the incorrect flue siting is resolved.
As for the brickwork. it looks like a standard BG brick up to me.
