Connection behind bathroom mirror?

[B1gSte]

Hi everyone. Could someone please explain how an LED bathroom mirror with shaver socket should be connected to the mains?
My interpretation of the regs is that a fused spur must be outside the zones.
However, can the flex be connected in the void behind the mirror and by what means?
I am not making the connection myself. This is part of an extension build (en suite) and I’m just trying to make sure that everything is in the wall ready before the boards go over the studwork.
Any advice appreciated. Thanks.

Last few of these I've done have come with a pre installed flex, and very little space behind the mirror for a connection. I had been using the wago box lite boxes to make the connection behind the mirror, but this often requires chiselling a pocket out of the wall for the wagobox so the mirror sits flat. On future jobs I'm going down the route of using a 25mm back box and flex outlet plate with a bottom entry. Easier to do the chiselling at 1st fix!

I have an IP44 rated mirror with demister, shaver socket and led perimeter light. Led and demister controlled by proximity sensor not by light switch. Rather than connect to the lighting circuit the power was spurred off the ring via a double pole switch (in the loft) with a drop to the mirror. Cable pokes through the tiled wall and silicone sealed. Then goes into a Schneider IP44 round junction box fixed to the wall. Flex to mirror connected via wago’s inside. The mirror has a 50mm gap behind so jb can be accommodated.
We were concerned that a standard back box with flex outlet, recessed into the wall, would not quite manage IP44 with all the steam about even though it could have been (just about) mounted outside Zone 2 if we had known the exact fixing height before first fix. And fiddly 4 keyhole fixings for mirror. Should sparks have fitted a switched fused spur in the loft rather than a double pole switch for isolation?

If you’ve spurred off the ring final circuit, you’ll need to replace the DP switch, with a Fused Connection Unit, with switch if you like. Use a 5A fuse. What does the manufacturers instructions say?

Without reading back, does your RFC have RCD protection?

Edit; I see your not the OP.

Thanks Midwest... yes, circuits have rcd protection. I will also double check the rating plate on the mirror as the installation instructions are silent!
