This is an Economy 7 tariff with separate day and night rates. We show both, but we do not rank it or quote an annual cost: the time the meter switches between them is set per meter and per region, and is not published. Costing it would mean inventing that switching time.
A quick suitability check before you compare the live price with your own home and usage.

About Octopus Fixed Economy 7
Octopus Fixed read on an Economy 7 meter: two registers, a lower rate for the overnight block and a higher one for the rest of the day, with both held for the length of the contract rather than reviewed periodically. This page shows the day and night rates the catalogue publishes for each region. It is deliberately left out of the rankings and shown without an annual cost, because costing it would mean assigning each half hour to the day or the night register, and the switching time that decides this is set per meter and per region and is not published anywhere.
