    You'd price around all of that for that amount of cable
    Make sure you get from a reputable supplier

    Any of the wholesalers would deliver

    16sq is big money seems to be up around 7/8euro a meter if I'm not mistaken

    Have you calculated your cable size and explored other options such as new connection?

    Would have gone down new connection road only low usage charge makes it viable as low power usage. But at moment served by 2.5 which putting it mildly is v dangerous due to long draw. So looking at better option at best price.

    16 sqmm. I assume that you are using this size for voltage drop reasons, given the distance. Is it necessary, I wonder, to have to use such a large cross sectional diameter?

    The voltdrop for 10 amps is over 7 volts for 300 meters. That only leaves about 2 volts for either side of the cable?

    Point taken Frankmul. Yes, even with the proposed cable only about 2kW possible in the shed.

    it's too far with the price of cable now

    if it was just for lighting and you could use a smaller cable maybe

    Not a good idea as voltage drop too much on 2.5 wire

    I was referring to lighting only ,it may have been possible to calculate something slightly smaller

    even 16sq is undersized for lighting and power
