Yea, looks shoddy don’t it, this is how it was hiding behind the wall, probably from new build in 1995
If it's tucked behind a wall it needs changing to a maintenance free type.

Maybe.
Depends what's inside it.
The sticky tape is a sign of poor workmanship.
Have you got a multimeter?

It could be 'worse' than that. There is an ominous 'bulge' within the tape (connector block or somesuch?), and it looks as if conductors from the top-left cable are 'entering the tape' without their outer sheath!

I will tidy that up and whack a maintenance free box on. I should only need a live and neutral from here as I am not wiring to the light switch and the fan has a sensor on thatvwill turn it on and off. Is my plan sound please?
Live and neutral and earth. the cable will need a CPC, even if the fan doesn't need one.
Is that a movement or a humidity sensor?
Take a switched live as well, for when you find out that sensors are not as good as you hoped.
Humidity sensor
Definitely needs a switch as well.
I don't think that he'll find a 'switched live' (I imagine you mean 'switched by lighting') at a JB serving two "shaver plugs"!

Technically to each point in wiring and at each accessory. It's not the cable which requires it. (Otherwise how would singles be used?)
There is little correct about how that has been terminated, including things as basic as the junction box not being secured to the building fabric and cables not clipped entering it. (Also obviously the sheath not entering the enclosure etc.)
I’ve found a better looking one lower down the wall which I will use instead of the other, I will leave that one be.
I have bought some twin and earth 1.5mm cable which I will attach to the unction box and then up through to the loft and into the new fan, does this sound like a plan please?
What are the numbers for on the junction box please?

They indicate how you should rotate the lid/cover so as to 'unblank entry holes in the side, depending upon whether there are 2, 3 or 4 cables entering the box.
As previously said, that type of JB is only acceptable if it is 'accessible'. It also needs to be screwed down to something, and all cables entering it should be clipped to something fairly close to the box.
