Octopus Energy tariffs explained
Flexible Octopus (Standard Variable)
The default, no-exit-fee tariff that moves in line with Ofgem’s quarterly price cap. It’s simple and widely available. Unit rates and standing charges vary by region and meter type.
Fixed Tariffs
Locks in unit rates for a set term (e.g., 12 months). Ideal if you want price certainty. Early exit fees may apply if you leave before the end date. Availability changes with market conditions.
Octopus Go
A popular time-of-use tariff with a cheaper overnight period designed for EV charging. Requires a smart meter. Great for drivers who can schedule charging off-peak.
Intelligent Octopus Go
A smart EV tariff that automatically schedules your charging for the greenest and cheapest periods overnight. Works with compatible cars/chargers and a smart meter. You retain manual control when needed.
Octopus Cosy (Heat Pump)
A dual-rate smart tariff with cheaper periods to run heat pumps efficiently. Requires a smart meter and is subject to eligibility and device compatibility.
Agile Octopus
A half-hourly dynamic tariff reflecting wholesale prices each day. Prices can be very low at off-peak times but may be higher at peaks. Best for savvy users who can shift usage. Smart meter required.
Octopus Tracker
A daily price tracker linked to wholesale costs, offering visibility and the potential for savings when market prices are lower. Availability is limited and may operate on a waiting list. Smart meter required.
Octopus Flux (Import + Export)
Designed for homes with solar PV and batteries, Flux offers a three-rate structure that rewards importing and exporting at times that support the grid. Pair with Outgoing Octopus for export payments.
Outgoing Octopus (Export Only)
Earn for the electricity you export back to the grid from solar PV or other microgeneration. Options include fixed and agile export. Smart meter required.
Octopus Fan Club
Community-linked tariffs that provide local savings when nearby wind turbines generate strongly. Availability is limited to Fan Club areas.
Tariff availability, rates and eligibility change frequently. Smart tariffs typically require an operational smart meter and compatible devices. Always check live options during your quote.
Smart meters and the Kraken platform
Octopus Energy’s Kraken technology powers fast, reliable service and enables innovative pricing. With a smart meter you can see usage in near real time, unlock smart EV, heat pump and solar tariffs, and automate charging or heating to cheaper, greener times.
- Half-hourly data enables time-of-use savings opportunities.
- Insights help reduce waste and shift usage away from peak times.
- Easy switching and seamless tariff changes in your online account.
Prices, standing charges and the Ofgem cap
Unit rates and standing charges vary by region, meter type (single-rate, Economy 7, smart) and payment method. The Flexible Octopus tariff follows the Ofgem price cap, which updates quarterly (January, April, July, October). Fixed and smart tariffs can price differently from the cap.

Octopus Energy FAQs
Are Octopus Energy’s tariffs price-capped?
Only the Flexible (standard variable) tariff is directly affected by the Ofgem price cap. Fixed and smart tariffs are set independently and can be above or below the cap, depending on market conditions.
Do I need a smart meter?
You can join on a standard tariff without a smart meter. Smart meters are required for Agile, Tracker, Go, Intelligent Octopus Go, Cosy and Flux. Octopus can arrange a smart meter install at no extra cost in most cases, subject to availability.
What about exit fees?
Flexible Octopus has no exit fees. Fixed and some specialist tariffs may include exit fees if you leave early. Always check the tariff terms before you switch.
Can I get paid for exporting solar?
Yes. With Outgoing Octopus or Flux (for battery-equipped homes), you can receive export payments for energy you send back to the grid. A smart meter and export registration are required.
Do they offer prepayment options?
Octopus Energy supports prepayment (PAYG) accounts. Rates and features differ from credit tariffs, and device compatibility may be required. Check availability during your quote.
How long does switching take?
Most switches complete in around 5 working days under the industry’s Faster Switching arrangements, often sooner. There’s no supply interruption.
Is Warm Home Discount available?
Octopus participates in the Warm Home Discount scheme. Eligibility and payments are determined by government rules and can change each year. Check current criteria during winter application windows.
