Every Octopus import tariff in your region, ranked on the same month of real rates. The cheapest average isn’t automatically the cheapest for you — the notes below say why.

Economy 7 tariffs are absent from this ranking, and a standing charge shown as unknown is one we can’t stand behind rather than one that’s free.

The catch with a ranking
A cheap average doesn’t mean cheap for you. Agile only wins if you can move your usage; Go only wins if you charge overnight. This list ranks the rate, not the fit.
Rank them against my own usage insteadTwo tariffs are missing
Economy 7 tariffs aren’t ranked here. Costing one means assigning every half hour to the day or the night rate, and that switching time is set per meter and per region — it isn’t published anywhere we can read.

How the ranking is worked outRead more
Rates are profile-weighted across half-hour slots over the last complete calendar month, on the typical single-rate household pattern. The standing charge is carried separately and never folded into the unit rate, because the two are billed differently.
Historic profile-weighted evidence, not a bill, forecast or switching quote. Standing charges remain separate.
Why some standing charges say “unknown”Read more
A standing charge published as exactly zero could be genuine or a gap in the supplier’s feed, and the data carries no flag to tell them apart. The difference is worth roughly £163 a year, so we say unknown rather than free.
