Points are interactive: hover, focus or select one for exact values. The line is the plain average of the regional monthly means — all 14 regions, in every month — and the shaded band runs from the cheapest of those regions to the dearest in that month. So the band is the spread BETWEEN regions, not the spread within a month — a regional page’s chart shows the latter. Nobody pays the line; it describes the country rather than a bill. 3 periods are drawn from part of the calendar rather than all of it: Oct 2022 (4 of 31 days), Nov 2022 (6 of 30 days), Sept 2026 (12 of 30 days). A month is partly counted where a version went on or came off sale inside it, and the current month is always still in progress. They are drawn hollow.

About Octopus Tracker

Variable electricity rates tied directly to wholesale prices. Prices update daily, giving you access to lower rates when wholesale costs drop. Octopus Tracker offers a transparent pricing model: your rate is based on what Octopus pays for electricity on the wholesale market, each day Octopus sets a new rate from current wholesale prices, and you can see how wholesale prices affect your rate. Tracker rates can fluctuate. While you can save when wholesale prices are low, rates can also rise when wholesale costs increase, so this tariff carries more price risk than fixed-rate options.

Questions, answered

What is Octopus Tracker?
Octopus Tracker is a variable electricity tariff where rates are tied directly to wholesale electricity prices. Your unit rate changes daily based on what Octopus pays for electricity on the wholesale market, potentially offering savings when wholesale prices are low.
How often do Tracker prices change?
Tracker prices update daily. Each day, Octopus sets the rate based on wholesale market prices. This means your rate can go up or down from day to day, depending on market conditions.
How does Tracker behave against other tariffs?
Tracker can work out lower than standard variable tariffs when wholesale prices are low, but rates can also rise when wholesale costs increase. It offers transparency: you pay close to what Octopus pays for electricity, plus a small margin.
Do I need a smart meter for Tracker?
No, Tracker doesn't require a smart meter. It works with traditional meters, making it accessible to more customers.
How does Tracker compare to Agile?
Tracker updates daily with a single rate for the whole day, while Agile changes every 30 minutes. Tracker is simpler and doesn't require a smart meter, while Agile offers more flexibility and can go negative during high renewable generation periods.
Can Tracker prices go negative?
No, Tracker prices are always positive. Unlike Agile, which can have negative prices during periods of high renewable generation, Tracker maintains a minimum floor price.
What happens if wholesale prices spike?
If wholesale prices rise significantly, your Tracker rate will increase. However, Octopus typically includes a price cap or protection mechanism. It's important to monitor prices and be aware that rates can fluctuate.
Are there different versions of Tracker?
Yes, Octopus has released multiple versions of Tracker over the years. You can view prices for different Tracker versions to see historical rates and compare how they've performed.
