Save on energy costs with the Octopus Energy Tracker Tariff

The Octopus Energy Tracker tariff offers customers access to gas & electricity at prices that are below the government cap. These prices follow wholesale rates, and are currently ~30-40% cheaper than the cap. You can get a £50 bonus when you switch to Octopus Energy (see FAQs), and then benefit from energy prices that track wholesale rates. But beware that rates could go above the cap.

Updated with the new Ofgem price cap, effective from 1st October 2023. Twitter updates show tomorrow’s rates. Agile price comparison shows yesterday’s rates.

I’m currently updating the page with new (future proof) graphs, these include more tariffs!

This page provides a comparison of the Octopus Energy Tracker Tariff and the Octopus Energy Flexible Tariff, and the Octopus Energy Loyal Fixed Price Tariff. The Flexible Tariff is Octopus’s government cap tariff.  The graphs were made using a little bit of magic via and the Octopus Energy REST API. If you want to see data for any other Octopus Tariffs, send me a message on Reddit and I will see what I can do.

Note: The data on this page updates daily, and headline costs/savings are posted to Twitter too.

Comparison of electricity rates on Flexible, Tracker and Agile

The graph below shows a comparison of electricity unit rates on the Flexible, Tracker (Nov 22) and Agile tariffs. Note: the Agile tariff actually is a half-hourly demand tariff. Rates change every 30 minutes, based on forecasts from the preceding day. Agile has cheaper rates in off-peak periods (e.g., overnight), but higher prices when everyone is boiling the kettle. For ease of comparison, the graph only shows yesterdays rates for each tariff. And the rate shown for the Agile is averaged over the entire day.

Use the following filters to set the graph to your region and energy usage:

In case you were wondering, I don’t work for Octopus Energy. I just read about the Tracker tariff on r/beermoneyuk and signed up because it made sense for me to do so. And then I made these tools so that I and other people on Reddit can track the prices (it initially started with a Google Looker Dashboard that you can find here). If you sign up with my refer-a-friend link*, we will both get a £50 bill credit from Octopus (or you can enter the referral code glad-frog-421). And maybe I will be able to afford to keep this website going.

Frequently Asked Questions

How do I sign up to Octopus and access the Tracker?

Due to popularity, Octopus introduced a wait list for the Tracker tariff in 2023. In July 2023, Octopus opened it back up again to existing Octopus customers. To gain access to the tracker rates, you must:

Do I need smart meters to join Octopus?

No - you do not need smart meters to join Octopus and receive the £50 bill credit. However, you need smart meters to join the Tracker tariff.

How can the Tracker beat the government cap?

Because wholesale gas & electricity prices are currently lower than fixed rate prices. Octopus allows customers to pay these rates (with a margin built in for Octopus' profit).

If prices go up, can I switch back to the Ofgem Cap tariff (Flexible)?

Yes. That is why I built the comparison dashboard. Keep an eye on prices, and if they go above the cap then you can switch back to the Flexible tariff. However, if you leave the Tracker, you cannot rejoin it for 9 months.

Is it easy to switch back to a fixed tariff?

Yes - to switch back, you just choose a different tariff on your account page. Alternatively, email or phone Octopus. However, Octopus states switching to another Octopus Energy tariff may take two weeks.
