My 89 y/o mother can no longer reach the switch above the mirror
and I want to change it for a LED pullcord light.

The old light was installed by a bathroom fitter and was not
earthed.

This light requires an earth connection but further
investigation has revealed that her upstairs lighting circuit
has no earth.

Can I borrow an earth from an accessible ring-circuit in these
circumstances?

Depending on your situation, I wonder if it may be easier for
your mum to have a motion sensor switch. It could be a
replacement for the existing switch or some bathroom light
fittings come with one built in.

I think the issue is the light doesn't have an earth connection.

A pull cord switch doesn't need an earth.

I have often thought passive IR motion sensors are not used often
enough, but if still in a bath, such a switch is of little use,
and a pain if you actually want darkness.

I think there are some sensors which use RF and are exceptionally
sensitive compared to infrared. I can see times when an on or off
override would be useful but for most of the time sensor-based light
could be very convenient.

I popped a couple of battery operated PIR lighting strips into the
bathroom (one is stuck under the bathroom cabinet and provides
temporary lighting when you wash your hands). I would like to have
ther main light on a sensor but the extractor fan comes on for 20
minutes when the room light is operated and it can be a bit
annoying.

Switch it off before putting the light on?
