that's what I call spaghetti junction cabling .

Wow are those un-insulated links for real?
just love those bare links at the top. waiting to give the unwary a bite.
Yep.
Owner swears it was done by a proper Spark and wouldn't blame Mr Plumber (I admit that I did try to get him over that line). Even more badness - the single retaining screw for the wiring centre cover was missing - so half asleep first thing I opened the cupboard, bumped the box and the cover fell off, revealing all its naked glory.
. They've got brooms and stuff in there and it's just luck no-ones been hurt. It also has a 3kW immersion running on 1mm flex from a 13A fcu. It was on when I got there (don't ask me why... ) and the cable and fcu were toasty. Freed up the CH valve, took fuse from immersion, secured the wiring centre top and beat a hasty retreat for today. I'll go back later in the week and make it presentable.
post a pic when done.
I'm sure I can improve it, but this mob are a tough audience
go on give it a go it want harm any body .
wilko. whats with the earth tails and brown & blue tails in block connecter 14.
I'm probably being optimistic but perhaps they are spare cores that have been earthed?
As all cables entering the heating jb are flexes.
To be honest I can't make out were any of the earths terminate to.

if I was you wilko I would take wiring diagram if possible.
Agree, I will do !
It may be a trick of the pic, but thank you @buzzlightyear for pointing it out
I haven't changed anything in the wiring centre, just used the trusty 2 pole voltage detector on the terminals. So whatever it is, it's been that way for some time. I've arranged to go back tomorrow morning so next pic might be sooner than I thought.

You've got cable clamps, so you'll be fine
Went back this morning and it turns out the br, bl and g/y in connector 14 that @buzzlightyear spotted was close to a bang. The g/y was an unsecured cpc that was floating about in that connector . Top left pic shows it where I've just pulled it down away from them. Got rid of those bare links and then noticed many of the flex cables were damaged by cuts. So I went through and fixed them. Replaced the somewhat golden brown pvc flex 1mm that'd been cooked by the 3kW immersion (now high temp 2.5mm flex) and ditched the fcu for a 20A flex outlet and DP sw with some 2.5mm t&e replacing even more 1mm flex . I'm not happy with the neatness of the wiring centre, but it is safer and easier to see where the cables come from.
