Octopus Tracker prices
A single electricity and gas price per day, following wholesale costs.
Your postcode is sent once to Octopus Energy’s public region lookup — the same one they bill from. We do not put it in the URL, analytics or database, and do not keep it.
Octopus Tracker sets one price for electricity and one for gas each day, following wholesale costs. It is the middle ground between a fixed tariff that never moves and Agile, which moves every half hour.
It is also the only Octopus smart tariff that applies the same wholesale-linked approach to gas, which matters if gas is the larger half of your bill — as it is in most homes with a gas boiler.

Against the price cap in London
The Ofgem cap for a single-rate direct debit meter here is 26.35p per kWh plus 44.78p a day. Today this tariff averaged 1.39p below the cap unit rate.
This compares one day’s unit rates only. What you pay also depends on the standing charge and on when you use electricity, so treat this as an indication rather than a saving. Cap period 2026-07-01 to 2026-09-30.
Estimated annual cost
£800a year
2,500 kWh a year in London, at 25.82p per kWh plus 42.42p a day standing charge.
Our estimate, using the average price Octopus Tracker actually charged over the last 31 days. Octopus Tracker prices change through the day, so what you pay depends on when you use electricity — this assumes you use it at the same times as an average household.
Octopus Energy quotes £856 for the same household. Their figure charges every unit at the tariff’s standard rate of 28.06p, which is what you would pay having shifted nothing at all. Treat it as a ceiling rather than an expectation.
Gas
Today’s gas rate is 7.57p per kWh, plus 29.47p a day standing charge.
Gas is priced once per day with no time-of-use element, so there is nothing to shift and no cheaper hours to aim for. Tariff code G-1R-SILVER-26-04-01-C.

Context
Two versions of Octopus Tracker are running
Octopus Energy keeps existing customers on the version of a tariff they joined on. Both are live in London, and over 89 days when both published a price they differed by 0.79p per kWh on average, with the current version the dearer of the two.
The current version was dearer on 100% of those days, so the gap held in one direction throughout this period rather than swapping about. Averages over the period: 24.47p on SILVER-26-04-01, 23.68p on SILVER-25-09-02. It is measured in London and differs by region.
Switching tariff moves you to the current version, so it is worth knowing which one you are on before assuming a change would save you anything.
The price cap since Oct 18
A year of energy at typical consumption, paying by direct debit. This is the benchmark every tariff on this site is measured against, and it is a Great Britain figure rather than a regional one.
The cap peaked at £3,582 in Jan - Mar 2023 and stands at £1,663 for July - Sept 2026.

How Octopus Tracker works
Each day Octopus publishes a rate for the following day, derived from wholesale costs, and that rate holds for the whole 24 hours. There is nothing to time within the day: electricity at 3am and 6pm costs the same.
Both fuels are priced the same way. The gas rate and the electricity rate move independently, because their wholesale markets do.
Because the rate is fixed for the day, the tariff rewards using less rather than using at different times. That is the opposite of Agile, and the reason the two suit different households.
What you need
- A smart meter sending readings, for both fuels if you take gas as well
- Availability has historically been limited at times, and Octopus has capped signups in some periods
- Available across Great Britain, priced by distribution region
What drives what you pay
- Wholesale gas and electricity prices, which move daily and can move sharply
- How much energy you use, since there is no timing advantage to exploit
- Standing charges on both fuels, which apply every day irrespective of usage
- The weather, more directly than on most tariffs — a cold snap raises both demand and wholesale prices at once
Who it tends to suit
- Households that want wholesale-linked pricing without watching every half hour
- Homes wanting the same approach applied to gas as well as electricity
- People who would rather use less than re-time their day
Who it tends not to suit
- Anyone who needs a rate they can predict months ahead for budgeting
- Households that could shift usage within a day — Agile rewards that, Tracker does not
- People uncomfortable with a price that can move every day
Things to watch
- A daily rate means daily exposure. In a sustained price spike there is no fixed rate protecting you and no cheap window to move into.
- You take on price variability without a way to act on it. Some people find that harder than Agile, where you can at least respond by shifting usage.
- Signup availability has been restricted at points in the past, so it is not always open to new customers.
Octopus Tracker compared with the alternatives
- Against Agile Octopus
- Agile moves every half hour, Tracker once a day. Agile pays you for shifting usage; Tracker does not, because there is nothing to shift into. Choose Tracker if you want wholesale pricing without managing it, and Agile if you will genuinely change when you use electricity.
- Against Flexible Octopus
- Flexible follows the Ofgem cap and changes quarterly; Tracker follows wholesale and changes daily. Tracker tends to be cheaper when wholesale prices sit below the cap and more expensive when they spike above it. The cap comparison above shows where today sits.
- Against A fixed tariff
- A fix buys certainty at a premium. Tracker gives up that certainty for prices that follow the market down as well as up. If a predictable monthly figure matters more to you than the average outcome, a fix is the better choice.
How to switch to Octopus Tracker
- You cannot join Tracker directly from another supplier. New customers sign up to Flexible Octopus first, then request the switch once they are on supply.
- A working smart meter sending automatic readings is required. If you have an older meter, Octopus will fit a smart one free and you stay on Flexible until the engineer has been.
- With a smart meter in place, you request Tracker from the online dashboard or the app. It takes a few days for billing to align, after which your daily rate updates each midnight.
- There are no exit fees, but leaving blocks you from rejoining Tracker for nine months. That rules out the obvious tactic of taking it through summer and hiding on a fixed deal each winter.
Our verdict on Octopus Tracker
Tracker is an effective way to cut a bill if you can accept daily price changes. For most households it is the practical route to wholesale prices without the daily attention Agile demands: one rate for the whole day means you run the house normally and still benefit when it is mild and windy.
It is not for the risk-averse. A hard winter cold snap pushes the daily rate up sharply, and you have to budget for that. The nine-month block on rejoining means the decision to leave is close to final for the year, so if you want certainty over your unit rate a fixed tariff is the safer choice.
In its favour
- Often well below the Ofgem price cap
- No exit fees
- Zero-carbon electricity
- Covers gas as well as electricity
- One rate a day is far easier to live with than 48
Against it
- Rates can climb quickly in winter or a supply shock
- Leaving blocks you from rejoining for nine months
- Needs a fully working smart meter
- No green gas or offsetting on the gas side
Frequently asked questions
Do I need a smart meter for Tracker?
Yes, and it has to be sending automatic readings. If you do not have one Octopus will fit it free, but you stay on Flexible Octopus until the installation is done.
Is Tracker protected by the Ofgem price cap?
No. As a smart tariff its daily rates sit outside the default tariff cap. Octopus applies its own hard ceiling instead — 100p per kWh for electricity and 30p per kWh for gas — which is far above anything the cap would allow.
Do I have to change when I use my appliances?
No. Unlike Agile, Tracker sets one rate from midnight to midnight, so there is no cheaper hour to aim for. The question is whether the day as a whole is cheap, not which part of it.
Is the gas on Tracker green?
No. The electricity is matched to zero-carbon generation, but the gas is standard natural gas. Octopus discontinued its gas-offsetting tariff in 2025 and no longer offers a green gas option.
Does Tracker cover gas as well as electricity?
Yes, and it is the main reason to choose it over Agile. Both fuels are priced daily from wholesale costs. Today’s gas rate is shown above alongside electricity.
How often does the Tracker price change?
Once a day. The rate is published the day before and holds for the full 24 hours, so there is no cheaper time of day to aim for.
Is Tracker cheaper than the price cap?
Sometimes. It follows wholesale costs rather than the cap, so it can sit below the cap for long stretches and above it during a spike. The comparison above shows today’s position for your region.
Can I switch away if prices rise?
There are no exit fees, so you can leave at any time. But Octopus enforces a nine-month cooldown: once you leave Tracker you cannot rejoin it for nine months. That rules out taking it for the summer and moving to a fixed deal each winter.
