Not only that, but Octopus Go is electricity only and I’d have to find a Gas only tariff.
Why?
I feel like your entire sample there is off. Did you normalise your numbers prior, or are you comparing pre-april 22 tariffs with post-april 22 tariffs here?
Also, why do you argue that you need to find a new gas tariff when switching your electricity tariff? We were on fixed rate for electricity as well as gas, we changed electricity to Octopus Go and kept the fixed rate for gas.
That makes me wonder if you’re on some kind of combined fixed tariff that Octopus took over when your other supplier went bust, in which case your math again is off since the price will increase either way to close to what Go is already.
Also, your sample assumes 24h of high rate electricity, minus what you charge. In reality, 15% of your consumption (average, ish) is discounted, since Octopus Go discounts all electricity usage, not just car charging. You can increase that if you set timers for washing machines/tumbles too, to run in the discounted timeframe.
