Agile Octopus review (November 2026)

Electricity only. If your home uses gas you need a separate gas tariff, which you can still hold with Octopus — only the electricity is priced half-hourly.

No, though they help most. A household that can move the dishwasher, washing machine and tumble dryer out of the 4pm to 7pm peak can still come out ahead. How far ahead depends on your region and how much you can shift, and it is not guaranteed — at times a flat tariff works out cheaper.

There are no exit fees, so you can move back to a flat tariff whenever you like. Leaving does lock you out of Agile and every other smart import tariff for 30 days, so it is worth being sure before you go.

Agile is billed from half-hourly readings, so it needs them. Octopus may estimate short gaps; if it cannot obtain or estimate the readings, it can charge the affected consumption on Flexible Octopus using typical consumption patterns instead.

Agile is built around half-hourly credit billing, which does not translate cleanly to pay-as-you-go top-ups. If you are on prepayment, check with Octopus before applying rather than assuming.

Prices for the following day normally start appearing from 4pm, but Octopus's terms allow publication later in the evening. Until they are actually present, this page says they are not yet published rather than showing an empty chart.

Yes. When wholesale prices fall below zero, usually on windy nights with low demand, the Agile rate can too. During those periods you are credited for electricity you use rather than charged for it. The page counts how many such periods there are today.

Yes, the unit rate is capped, so there is a ceiling on any individual half hour. The cap does not stop a whole day being expensive, though — it stops a single half hour being unlimited.

In practice, yes. Agile rewards moving usage into cheaper half hours. A household that uses electricity at the same times regardless of price may well pay more than on a standard tariff.
