Plug socket replacement gone wrong (help?!)

    So, I tried to change my first plug socket.

    Unfortunately, my new socket did not seem to fit my backbox (even though I thought they were all universal).

    I therefore removed the new plug face to put the old one back on. Unfortunately, moving the wires around mean they are not neatly twisted again. Although all the power is off, I don't want to touch them, just in case.

    When they go in the old socket, there is exposed copper between fixing and installation.

    So, I don't know what to do. How much will a sparky cost (and to replace the other 7 while they are at it).

    What should I do in the meantime? I can keep the power to the plugs off, but don't know how else to be safe.

    Photo 1 is back of old and new.
    Photo 2- live wire exposed at the back of plug
    Photo 3. Old plug wired originally

    Possibly the unused top and bottom lugs on the back box need bending back to accommodate the new socket.

    The wires can be neatly twisted with insulated pliers.

    If you don't feel confident doing this work, employ an electrician.

    You are fitting on to a 4 lug box, it is likely your new socket will foul on the top and bottom lug, you will likely need to bend them out the way before anything else.
    As for the wires it is best they are not twisted but straight and flat

    Thats a very shallow backbox for a socket, the original is obviously shallower than your replacement.
    The cables have been cut very short so you are going to struggle with any new socket where the terminals aren't in the same position as the original, doesnt look as if there's room there for terminal block either.
    You'll need pliers to remake the twists in that stranded cable.
    Options.
    1 Make a right mess by chopping that old backbox out, chase the wall deeper to accept a 38 or 50mm backbox, use terminal block to extend those cables to fit to new socket.
    2. Carefully retwist the old cables together. Clean that old socket up (emulsion will come off usually with a fingernail), refit it.
    3. Call an electrician, be prepared to part with £50 or so EDIT for each socket

    If you don't have the confidence or tools to do 1 or 2 then you will be safe if you leave the power off and make sure anyone else in the house knows why the power is off (if its old rewirable fuses, keep the fuse in your pocket and tape over the fuse carriers). Ideally you would make live and neutral safe with terminal block or WAGO connectors.

    There's a plug on the other side of the room which pulls out less than a 1cm

    25mm is the standard depth for a socket box.

    The alternatives are 35mm or 47mm.

    Sparks are often really tight (mean) with cable, especially those of yesteryear.

    One guy I knew would wire up the socket, screw it to the box, then pull the cable tight so once the circuit was installed, there was very little movement when you unscrewed the accessory.
    He proudly told me he saved a few metres of cable for every rewire.

    I said I'd use extra cable and charge the customer for it, he looked at me as if I had a strangely shaped green head.

    Is it buggery.

    At worst it's a 25mm deep box, set about 10mm back from the wall finish, so probably around 35mm deep in total.

    The top and bottom lugs are in the way.

    the things the screws go into.

    put a chisel or large screwdriver on the top and bottom one and give it a
    Whack with a hammer

    I think they mean the metal screw lugs (you have x4) top, bottom, left and right. Left and right receive the current screws for socket plate.
    Edit: @AndyPRK beat me to it ;)

    No idea, not a spark. Could just be so it can fit any way up?
