Hi Paul,
I don't like the look of this at all.
You would sort of hope that the supply to that equipment had been removed before the relocation took place, it's hard to say by looking at the pics, whether this in fact the case.
Is that the telecoms box sitting in amongst the grass there?.
One thing I have learned is that these tend to soak up moisture like a sponge.
I would hope that this set-up is merely temporary and relatively short-lived, because judging by the wall behind the alkathene sheeting, there seems to be a bit of a rising damp problem, not the sort of thing you want to mix with electrical equipment.
