Is this a safe (if unorthodox) way of wiring in a socket?

6 inches of 2.5mm cables doesn't worry me.

However putting 1mm cable (if a pair) and a 2.5mm (into 30A junction) may not result is a particularly good joint. Hence I said use a 20A junction

Good point EFLI. I suppose it's rather just the 'unattended' aspect of it being in the loft.

Having said all that, it's just occurred to me that I've got one plugged in in my loft that I've not looked at for about ten years!

Better get up there and look at it.

There is nothing wrong with having a few lights on a TV amplifier circuit.

wall-warts must be made to a European standard

Which does require a certain amount of "fusing" or thermal shut down ( thermal fuse ) but cannot cover every possible failure node. Some of the virtually impossible failure modes are not covered and fortunately they very seldom happen. One virtually impossible failure mode I have seen was a wall wart ( reputable manufacturer ) where an elecrolytic capacitor had exploded depositing aluminium foil. The foil shorted the mains before the fuse on the PCB and the case melted.

I am surprised about the comments on using 30A or 20A junction boxes. I have a couple of 20A ones as well (see photo) and cannot see why they would be any better. (If one had paired terminals so that the 2.5mm cable went into one and the 1mm into the other, maybe.)
Without extending the debate further than need be, is there any problem with using the 30A (3 terminal) box?

No mention of additional protection by means of a 30mA RCD...

OP, did you miss this post.
The Arial man may refuse to use an unprotected socket

I'll check the consumer unit when I get to my son's house - so far I'm going on his photo & emails.
