I have solar, 2 EV’s and on the Octopus Go tariff, currently 5p off peak and 16p peak but due to end and go up in price come August. I am in the process of applying for grants/cash back for battery storage and air source heat pump. There is £7.5k cash back in Scotland for the latter and 0% loans available. If all goes to plan I will be removing gas from my house completely and only using off peak and solar to provide energy to my house. I will need to revisit what deals are available come time jobs are done.
