Called octopus as I was getting an EV and did not have a smart meter installed for octopus go. Current duel tariff with them was coming to an end and I was looking for a new tariff which include gas and electric. Was told no problem put me on octopus helpful tariff fixed for 18 months at a rate of 28p daily change for both with electric charged at 10.40 a kW all day. Hope this helps and you can get this.
