Apologies if this is the wrong forum.
I am involved with a church with a 3 phase supply and a 14kWp solar panel installation. The cheapest supplier we can find (totalgp) does not offer a SMEG tariff and, until recently no supplier offered a 3 phase import - export meter anyway.
Is it possible to sell your electricity to a different company to your supplier. As this is not classed as a domestic installation the easy rules do not seem to apply and I'm finding it very difficult to find anyone who knows how to proceed.
