    I need to upgrade my meter tails to 25mm. The existing tails pass along under the pebble dash in plastic conduit (which would be too small), then apparently at an angle through the porch structure (unprotected) then turn sideways into a void & up the void to CU.

    I have seen other posts where the use of SWA is suggested but I haven't actually seen SWA with 25mm cores. "25mm SWA" appears to be 25mm "Outside diameter", so I presume that means the cores are smaller.

    Any suggestions as to the best approach welcomed. I actually think I will struggle with getting SWA through anyway even if it does exist with suitable cores, because of the bends involved.

    NB The meter box is under the window of the house rather than on the side of the porch, but the void inside the porch is set back behind the run of the outside wall so it's not possible to drill directly through the outside porch wall into it.

    25mm SWA is common stuff for example
    25.0mm² 6943X 3 core SWA Steel Armoured Cable

    You will have some challenges with bend radius. I assume that you will (have already) a switch/fuse at the cut out end? Due to the length of the tails?

    PS Why do you feel that an upgrade to 25mm is needed?

    You can get 25mm SWA cable, and bigger.
    Remember that if the tails are longer than 3 meters then you need to fit a fused isolator.

    Why do the tails need rewiring? What is the Earthing system?

    Isn't he (I hope) talking about the run from the meter to the consumer unit?
    @Msitekkie@Msitekkie can you clarify all our questions above please?

    I wonder how the cable conductors will be enclosed or the cable glanded for that matter.

    Trouble is Spoon he aint talking much, been quite for a couple of hours.
    Don't think the OP has factored that in. Offline as we speak.

    We can talk amongst ourselves whilst we are waiting - let’s face it, we normally do!
    Agreed it’s meter to CU. The Lord help him when he gets back to all the questions!
