    Octopus Energy Tariffs Compared

    Octopus runs the UK's most diverse range of tariffs — from half-hourly Agile to overnight Go, heat-pump Cosy and daily-tracking Tracker. Here's an independent breakdown of each, who it suits and where it falls short.

    Octopus Agile

    Half-hourly variable rate. Best for flexible households with a smart meter. Risky if you can't shift usage.

    Octopus Go

    5-hour off-peak window at ~8p/kWh for EV charging. Day rate slightly above the cap. Best for EV households.

    Octopus Cosy

    Heat pump tariff with two off-peak windows. Cheapest UK option for low-flow-temp heating. Peak rate stings if you can't avoid 4pm–7pm.

    Octopus Tracker

    Single daily rate for gas and electricity. Cheaper than the cap most of the year, painful during winter wholesale spikes.
