    My existing bathroom lighting switch has the shaver socket feed connected via the common. I would like to install a heated (anti condensation mirror) in the bathroom. Is it feasible to add this via the lighting switch through common live and neutral in addition to shaver socket? Appreciate part p requirements but looking for initial advice before engaging on the plan of action!

    Yes it's fine. Is the circuit on a 30mA RCD?

    Not at present but rather than add supplementary bonding I was going to ask the electrician to upgrade the consumer unit as part of the project. Is this a wise idea?

    All new wiring in the bathroom MUST be RCD protected. Replacing the CU is a great idea.

    If you wire it as you have suggested (I guess "common" means permanent live?) the heated mirror will be on all the time.

    You would need to add a suitable switch (somewhere) and remember to switch it on each time.

    If the loading is OK, it may be better to connect it to the switched live of the lighting circuit..

    As has been said, even adding supplementary bonding would not be an answer. To be compliant with current regs, all circuits in a bathroom (and not just in bathroom 'zones') have to be RCD protected - and that requirement does not go away if there is supplementary bonding. Although that requirement is not retrospective, I think most people would say that it does apply to any circuit which is modified or extended.

    Kind Regards, John

    Mine has a sensor on the bottom edge that you wave your hand under to turn it on and off. I don't know how common that is.

    thank you for the responses. It has it's own pull switch so permanent live would be ok... though thinking about I will either forget to put it on or turn it off!! maybe the switched side is a good idea. That does already have the lights and extractor fan though

    How many watts is the mirror heater?
    How many watts in total are all of the lights on that circuit?

    You'll be OK if the total is less than the value of the fuse on that lighting circuit.
