Thanks guys, interesting info. It's sounding like it needs to be replaced, see what the guy thinks, perhaps a warranty claim isn't that far fetched now I've seen what they look like internally.
Is this unvented cylinder a goner?

Sorry, you were right, thought it was dry this morning when I checked it but the hot water has been on and the top connection is manky and wet. As the water is rusty coloured it could be the stub that's at fault or it could be the casing I suppose? Are these top connectors replaceable? The water must be running around the insulation and finding multiple routes out hence it looking like it's rusted in lots of places.

Don't run that & isolate the mains water to it too and run the hot tap til it stops 
That's been doing that for not a considerable number of days to rust to that point.
If that goes then you'll know about it oh and there'll be a heck of a lot of water everywhere!
If that's been soldered, looks like it, probably been done in situ and flux could have got to it too

Blimey, thanks. I've isolated etc
It was dry this morning but I didn't take the insulation off, naivety as to how these things are put together! Given it's in a room we don't really have a need to go in, it was a fluke I spotted it at all as I was fitting a new radiator yesterday otherwise we'd probably never know until we had water everywhere.
It looks like the pipe has been soldered into the bit screwed into the top of the cylinder, it looks a right mess to be honest.
I'll update tomorrow when the eng. has been.
This unvented tribune suffered a slight leak in a prop early one morning
Funnily enough we had one of those at a previous house, I never really liked the look of it
The engineer has been and resolved the issue.
Turns out the original fitters thought it was a good idea to solder the elbow to the draw off pipe which isn't copper. Apparently OSO even provide a compression fitting for this which was obviously thrown away. It was always going to fail given what I was shown when it was taken off.
Thanks everyone for your input and help. Happy it was minimal cost and the tank didn't need to be replaced. Panic over lol

Quite. Not the best job on the world. The copper in parts looked like it had been annealed as they must have had to heat it for ages to get it to somehow take. Thankfully everything else is in order.
Picture is a bit blurry but the whole section of pipe has been replaced and a compression to the draw off. I just need to clean it/remove the dirt/stains etc
Jeez... It ain't rocket science. Who the fu¢k did it like that?
That's why MI's are the fitters' version of the 10 commandments!

Apparently their reputation precedes them. Can't think why! Craziest thing is it managed 12 years!
