    I am thinking the same as you Sunray, but obviously we don't encourage guesswork so didn't suggest it.

    I totally agree with your comment and I don't normally offer a 'solution' like this, I would more usually go down the line of offering advice on testing.

    However from my initial reading of OP this the solution I invisaged. This is amplified by one red not being doupled over and why I asked about the link wire.
    Then I saw the pic of the other switch which only confirmed all of my ideas.
    Additionally I believe there is little (if any) risk in this case if this solution is incorrect.

    THE risk that i perceive is a lack of earth on the faceplate.

    No it isn't. That's fake news.

    But common sense does apply in the UK

    Indeed. That is why I always say putting a 13 amp socket on a lighting circuit is bad practice. That is also why I say UK mains voltage is 240v not some arbitrary lower figure dreamt up by bureaucrats.

    The use of common sense when using that socket removes any suggestion of bad practice.

    You cannot assume your customer, or their family members have common sense, or even that they are aware of the sockets wiring status.

    But the applied lable will give the game away.

    BS7671 does not allow a Class I accessory to be earthed via the screws into the backbox.

    Neither ET101 or RECI apply in the UK. We work to BS7671 and a fly lead is not ‘required’, but is seen by some as good practice. Not fitting one does not contravene BS7671.

    Which reg says you can’t have an SO on a lighting circuit?
    The nominal voltage is 230V (single phase) and has been since 2003.

    It can do where there is no fixed lug.
