What is this pipe, please?

I doubt it was a plumber that did any of it tbh, most plumbers will use solvent weld fittings not push fit that you have there, I not sure any plumbers merchants will sell those they are more a B&Q thing.

Leak is much worse this morning, definitely coming from that little elbow joint at the top. I’m having someone out to replace the pipe work so hopefully that’ll fix the issue. Heating is on full blast due to the cold so I’m guessing that’s why it’s running that badly!

My boiler overflow pipe is curved in the same way, I believe its to stop hot water pouring outwards. The pressure drop suggests thats where its going. If properly installed the consensate pipe would drain directly into a drain. Can you trace the condensate pipe from the boiler?

There’s a pipe from the boiler than disappears through some chip board? I’ll post a photo. I assume this runs down through the ceiling and out but I assumed the little black pipe was the condensate pipe?

I see which tiny pipe is next to the elbow joint but I can’t see any water running from that. It’s definitely coming out of that black elbow type pipe at the top. Would a boiler have a separate pipe? Can’t see it serves anything else. Looked from above and can’t really see anything but the water definitely isn’t coming from the gutter. Many thanks!

That white pipe is almost certainly the condensate pipe. Where does it lead to, do you know - to the leaking black one that's outside?

(Can you confirm - it IS the black pipe with all the fittings that's leaking, and not the COPPER pipe? If it's the copper pipe, that's a separate issue and will 'leak' if there's a fault in your boiler - it has an open end. If the black pipe leaks, it's 'cos there's a bad joint there which should be dead easy to fix.)

There will be a 15mm copper pipe also coming out from the boiler and heading off to where the black pipe is - can you see that?

Does the dripping pipe look like this?

I think it leads to the outside, it’s certainly heading in the right direction for it to.  There’s a small box on the wall (on the inside) just next to the small window which I’m surmising houses some pipe work to the outside? 

It’s definitely the black pipe with the fixings that’s leaking. I can’t see any water coming out of the little copper outlet pipe next to it.

There’s a copper pipe in the photo above behind the white one, could that be the one you mean?

My guess that the white pipe leads to the leaking black elbow pipe outside and the copper pipe leads to that little outlet next to said elbow pipe, if that makes sense?

@Norman_Castle no, there’s a pipe like that up there though. See photo below where I think the drip/leak is

The copper pipe is almost certainly your gas pipe supplying the boiler.  If that was leaking, it wouldn't be wet and you'd probably know about it! 

The condensate pipe will indeed be producing more water because the boiler is on all the time.  Plumbers tend to work with white pipe indoors and they've switched to black outside to match the soil stack.  The pipe is leaking after it's left the boiler and is easily fixed by someone with a small amount of skill.    

Your chipboard in the loft is wet though, so the start of the leak could be near where you've photographed.  Just get the plumber to check all the joints when they turn up.   This is the simplest of problems, it shouldn't need forensic analysis.
