FYXO vs Octopus Intelligent Go

Octopus Intelligent Go is a well-regarded EV tariff: Octopus controls your charging to hit cheap overnight slots and gives a low off-peak rate, provided you are an Octopus customer with a supported car or charger.

FYXO takes a different approach. It is not a tariff and not tied to one energy supplier — it connects to devices you already own and shifts them to the cheapest half-hours on whatever tariff you are on, across EVs, batteries, hot water and more.

When Octopus Intelligent Go is the better choice

You are (or want to be) an Octopus Energy customer and your car/charger is supported.
You want the simplicity of a single supplier handling tariff and charging together.
Your only flexible load is EV charging and you don’t need whole-home optimisation.

When FYXO is the better choice

You want to keep your current supplier or tariff, or you’re outside Octopus’s coverage.
You have more than an EV — a battery, hot water, heat pump or appliances to optimise too.
You want price-following automation you control, plus AI-assistant (MCP) and API access.

FAQ

Do I have to switch supplier to use FYXO?

No. FYXO is supplier-agnostic — it works on top of your existing tariff, including dynamic and day/night tariffs, without switching supplier.

Can I use FYXO and Octopus together?

Often, yes. If you’re on an Octopus tariff, FYXO can still optimise your other flexible loads (battery, hot water, appliances) around your prices. Check your tariff’s smart-charging terms for any overlap on the EV itself.
