I am switching today to Intelligent flux. Going to try it out, I think the gains over the summer will offset the 13p increase in standing charges. In theory 1 peak unit exported covers it per day.
I based it on this
Electricity 8 APR 2024 - 7 MAY 2024
267.55 kWh We credited your account £40.13 £820.40
Electricity 8 APR 2024 - 7 MAY 2024
101.39 kWh We charged your account £16.89 £780.27
Not really imported much and those 100 units were basically just gaming agile when it was negative, most of the cost is standing charges.
