Upgrading your home with solar panels and a battery storage system is one of the smartest ways to reduce your energy costs and carbon footprint. To make the most of your setup, choosing the right tariff from your supplier is essential. Octopus Energy offer several time of use tariffs that reward solar users for shifting their energy consumption and exporting power back to the grid when demand is highest – helping you to get the best return on every unit your system produces.

Why Choosing the Right Tariff Matters

Traditional electricity tariffs charge a flat rate no matter when you use or export power. Octopus Energy’s smart tariffs work differently, they adapt to the times energy is cheapest to buy or most valuable to sell. If you own solar panels, battery storage, an EV or a heat pump, a time of use plan can greatly increase your savings allowing you to store cheap electricity and export it at premium rates during peak hours. 

Intelligent Octopus Go

Intelligent Octopus Go is ideal for homeowners who prefer automated energy savings. It provides six hours of low cost overnight electricity at just 7p per kWh, perfect for charging your EV or solar battery. Surplus energy is exported back to the grid automatically at 15 per kWh using the Fixed Outgoing tariff. Smart integrations for systems including GivEnergy, Enphase and Tesla Powerwall are handles automatically for maximum efficiency.

Octopus Go

If you prefer manual control over your battery system or don’t have a battery that is compatible with smart integration, Octopus Go is a great choice. Five hours of overnight cheap electricity at 8.5p per kWh for charging your EV or solar battery and a 15p per kWh fixed export rate. This tariff provides excellent value and flexibility without needing the automation.

Octopus Flux

Octopus Flux is designed for homeowners who want to maximise both import and export opportunities, offering three rate periods throughout the day. Octopus Flux lets you take advantage of cheaper electricity and premium export payments:

• Off-peak (2am–5am): Import at 14.99p/kWh, export at 4.74p/kWh
• Daytime (5am–4pm & 7pm–2am): Import at 24.98p/kWh, export at 13.32p/kWh
• Peak (4pm–7pm): Import at 26.6p/kWh, export at 34.97p/kWh

By manually managing when your battery charges and discharges, Flux can outperform many fixed rate tariffs, giving you greater control over your energy spending.

Intelligent Octopus Flux

Like Intelligent Octopus Go, Intelligent Octopus Flux is a fully automated tariff. Compatible with GivEnergy, Enphase and Tesla Powerwall systems, the tariff provides effortless optimisation for your home’s solar and battery setup. Using Octopus Energy’s virtual power plant system, it coordinates thousands of home batteries to charge during low cost, low carbon periods and export energy when demand (and prices) peak.

Octopus Agile

Octopus Agile is perfect for tech savvy homeowners who enjoy fine-tuning their energy usage. Octopus Agile tracks wholesale market prices every 30 minutes. Prices can even drop below zero, meaning you get paid to use electricity! You can also choose between a fixed outgoing rate of 15p per kWh or Agile Outgoing, which matches export payments to real time market prices. Agile is best suited to those who like to monitor prices closely and use smart automation tools to respond to market shifts.

Cosy Octopus

Cosy Octopus is tailored to households with solar panels and heat pumps. It offers three off-peak windows – 4am-7am, 1pm-4pm and 10pm-midnight – with electricity charged at 12.92p per kWh. This predictable schedule makes it easy to plan heating and battery charging around cheaper periods, perfect for homes looking to manage heating costs efficiently.
