Bathroom Extractor Fan Install

[RT1187]

Need to replace an old Vent-Axia extractor fan as the pull chord no longer works.

I bought this - https://www.amazon.co.uk/dp/B00CBX254I?psc=1&ref=ppx_yo2ov_dt_b_product_details

I went for this one as it only required a Live and Neutral feed. I installed it but nothing happens when I switch the electricity back on.

I noticed there is a Vent-Axia control box of some sort in one of the landing cupboards, could this be the reason the new one isn't receiving power? There is also what I assume is a pull chord for the shower on the opposite side of the wall from this, which I have never touched and is always On.

Is it something to do with the new fan having a permanent live rather that a switched live?

I've attached pics of the new fan (upside down I know, had to for the wire), old fan, in cupboard control box of some kind and in bathroom switch.

Thanks

It is an electric shower. It's a bungalow with a walk in wet room, used to be an old ladies house.

Yeah the isolator will be for that.

This is so much more complicated than it should be.

I ordered a 12V fan this morning with pull cord from Amazon, it just showed up and it has no pull cord or on/off switch at all. I am right in thinking if I install it it will just continuously run as it isn't connected to the light switch or anything? The wiring at the hole for the fan is just a blue/brown wire which I assume is just neutral/live?

I'm struggling to find a 12V Fan with pull cord anywhere, I'm not sure how the timer models work exactly but would that be a solution?

A couple of things to throw in the mix-

Do you know whether the transformer for the fan is 12V AC or 12V DC?

Do you know if the transformer actually works?

I'm really not sure how to check this.

The old fan was 12V so I'm guessing the transformer was working?

This is the old fan - VA100SVXHP 12 (Humidistat/Pullcord) | Vent-Axia - https://www.vent-axia.com/product/va100svxhp-12-humidistatpullcord
