It was my partner's mother who paid for it so I didn't have anything to do with it.

The drip is coming directly from the flue. There is a plastic pipe that runs from under the boiler through the wall and outside into the waste water pipe, I assume this is the overflow pipe.

No, that's the condensate pipe. The PVR overflow pipe will be in copper. 2 pipes, one flue.

Annoyingly the flue is parallel. Those solutions sound like they involve building work and for the sake of a drip I'll just have to live with it.

Thanks anyway.

Why? It's badly installed and possibly could invalidate the warranty, should you have a claim. Get the RGI back in to fix it at his expense, it just needs raising a tad at the exit end.
