Tariff guides
Octopus Energy tariffs explained
Octopus has a wider mix of standard, smart, EV, heat-pump and export tariffs than many people expect. This hub is not a promise that one tariff is always cheapest. Use it to narrow the shortlist, then check postcode rates, eligibility and device requirements.
Reviewed 22 May 2026. Source check, 22 May 2026: checked Octopus tariff, Agile, Go, Intelligent Go, Tracker, Cosy, Flux, Intelligent Flux, Outgoing and smart-tariff terms pages. Smart tariffs usually depend on a compatible smart meter and half-hourly readings. Prices vary by region and payment method.
Flexible Octopus
The standard variable option for electricity and gas. It is the simplest Octopus starting point, does not need a smart meter and is the tariff many new switchers use while checking whether a smart tariff fits later.
Best for: Households that want the simplest setup first
Agile Octopus
A half-hourly electricity tariff linked to wholesale prices. It can reward flexible homes, EVs and batteries, but it also exposes you to expensive peak periods and needs a smart meter with reliable half-hourly readings.
Best for: Flexible households that can avoid peak use
Octopus Go
A fixed smart EV tariff with a 00:30-05:30 cheaper overnight electricity window. It is simpler than Intelligent Go because the cheap period is predictable and does not depend on smart charging control.
Best for: EV owners who want a fixed overnight window
Intelligent Octopus Go
A smart EV tariff where Octopus schedules compatible cars or chargers. It includes a 23:30-05:30 whole-home cheap window, with extra smart-charging slots priced through the tariff rules.
Best for: EV owners with compatible cars or chargers
Octopus Tracker
A daily wholesale-linked tariff for electricity, gas or both. It is transparent when wholesale prices fall, but the Price Cap Protect ceiling is much higher than the Ofgem cap, so it is not a risk-free default.
Best for: People who understand daily price risk
Cosy Octopus
A three-rate smart tariff for homes with heat pumps, electric boilers or electric radiators. It gives cheaper periods at 04:00-07:00, 13:00-16:00 and 22:00-00:00, plus a higher 16:00-19:00 peak.
Best for: Homes that can shift electric heating
Octopus Flux
A solar and battery import/export tariff, currently unavailable to new customers according to Octopus. New switchers should treat this as legacy context and compare current export options instead.
Best for: Existing Flux customers and solar research
Before choosing
Four checks that matter more than the tariff name
Your meter and data
Agile, Go, Intelligent Go, Tracker, Cosy and Flux-style products rely on smart-meter data in different ways. Check that Octopus can read your meter before assuming a smart tariff is available.
Your biggest flexible load
An EV, heat pump, battery, storage heater or solar export setup can change the best answer. If you cannot shift much use, a clever-looking smart tariff may add risk without much reward.
Regional rates
Electricity unit rates and standing charges vary by region and payment method. Treat national examples as a steer, then use the postcode tools before switching.
Import and export pairing
Solar households need to check export eligibility as well as import prices. Go is only compatible with certain export tariffs, standard Flux is temporarily unavailable to new customers and Intelligent Flux is a separate battery-control route.
Source check
Check the tariff type before comparing prices
The names can sound similar, but the contracts behave differently. Go is a fixed overnight EV window. Intelligent Go adds supplier-controlled smart charging. Tracker can change daily. Agile can change every half hour. Cosy is built around heat-pump and electric-heating windows. Flux and Intelligent Flux are solar-and-battery decisions, not normal import tariffs.
Official tariff list
Use Octopus's tariff page for current postcode prices and historical tariff details before relying on any guide.
Smart-tariff terms
The terms explain half-hourly readings, missing-data billing and why third-party app screenshots are not billing evidence.
Export pairing
Solar homes should check Outgoing, Agile Outgoing, standard Flux availability and Intelligent Flux eligibility separately.
Choose your next step
Use the tariff hub by intent, not by tariff name
A tariff page is useful only if it leads to the right kind of check. Start broad if you are still learning the options, use live postcode numbers when the shortlist is real, then keep the referral route for the point where Octopus still looks like the right fit.
