Do you see anything wrong with this.

This is for 4 new spots in an ensuite and adding a mirror light and an extractor fan with isolation switch in an ensuite revab.

Is it possible to use a pull cord isolation inside on the ceiling in the ensuite rather than a switch on the outside.

Forgot to write switch on the square box on the diagram.

Will be using wago connectors.

Not an electrician!

When my bathroom mirror was put it, was advised it needed its own 2 pole isolation switch and its own rcd. This is in addition to it being fed from the lighting circuit that has a rcbo.

Also, re: mirror. Doesn't any electrical work in a bathroom (in england) need to be done by a competent person / not diy?

That advice was entirely wrong.

Ha! How so?

It did get me thinking thou.

Is it ok for twin and earth 1.5 for a mirror in bathroom.

That advice was entirely wrong.

Is everything fine in the diagram.

Is it possible to use a pull cord

Yes, if you must.

Is everything fine in the diagram.

The rest is ok.
Would suggest having a 3core& earth to the mirror, so you have both a permanent and a switched line there. Will allow the use of a mirror without it's own switch if one is wanted now or in the future.
Also 3core&earth to the light switch so you can have a neutral there, as a smart switch or similar device may be required in the future.
1.0mm² is fine. You can use 1.5mm² if you want, it will just cost more and be more difficult to terminate.

How so?

A mirror does not require an isolator of any kind, and the RCBO in the consumer unit provides the RCD protection. Adding another RCD achieves nothing other than the inconvenience of not knowing which of them or both would trip if a fault occurred.

Work within the zones of a bathroom is notifiable, so it depends on where the items will be installed as to whether the work is notifiable or not.

I think I will keep it simple and have it done as it's on the diagram. I think I know what you mean but I need to see it as a diagram before I'd even consider doing it your way.

Fully agree with also having a permanent live to mirror. Very useful if needed in future.

My side suggestions.
- you could also consider adding a shaver socket.
- I did like the idea of being able to isolate the fan, mirror and shaver socket (noting that this does not have to be done). So I put them all after the fan switch so I have one switch to isolate all the axillary items.

When I found that arrangement my first thought was 'what idiot did this' as the reported fault was shaver socket not working and the tenant didn't want the noise of the fan (but also complained about mould).

Second time I found that arrangement for a failed shaver socket (used for permanently charging 4 way toothbrush charger) my thought was 'what a good idea' while working with the light on.

So of I do this, add the 3 core and earth( brown, black,blue, earth) from the switch to the wagos then to the mirror as shown, I can turn the mirror off and on from the switch aswell rather than just from the mirror.

I have a few meters of this cable. It's not black, grey, brown and earth. It's round cable rather than flat. Would I still be able to use this for the isolater pull cord then onto the extractor fan.
