    I'm currently in the process of running neutral wires around my house to all the light switches so that i can install some of these new wifi smart switches to control all of my lighting.
    One of my light switches has a black and a blue wire connected together separately from the switch shown in the attached photo.

    How can i tell for sure if they are neutrals?

    Basic test equipment and basic testing skills will identify the wires.

    I've tried putting a multimeter to them and between live and the unidentified wires i get zero volts.
    What would you suggest?

    Time you have the switch off a tidy up would not go amiss :)

    Dug out an old multimeter with longer wires to test the continuity between the switch and the light. Turns out they are neutral.

    Win for me as i don't have to run a neutral to this switch now!

    I'm curious on how you are going to run Neutrals everywhere.

    All the switches are on stud walls. Downstairs are close to the landing which I'm waiting to carpet and then upstairs I'm going to try running them down from the loft. Will be interesting to see if it is possible or not.

    What type of wiring are you using for these new neutrals.

    They will require suitable enclosure/protection if they are not pvc/pvc insulated.

    Yes but not 16.0, you can get 1.5 though but can be hard to source.

    It's an off-the-shelf item here at wholesalers, though from what I gather is extremely uncommon in England.
