Understanding Octopus Energy Tariffs
Octopus Energy offers several tariff types, each suited to different households. This guide explains the key differences and helps you decide which is right for you.
Tariff Comparison
Tracker Dynamic
Unit rates change daily based on wholesale energy prices. Great when wholesale prices are low; riskier during price spikes. Requires smart meters.
Flexible Variable
Octopus's Ofgem price cap tariff. Rates change quarterly with the government cap. No exit fees, no smart meter needed.
Fixed Fixed
Locked-in rate for 12 months. Provides price certainty — you pay the same rate regardless of wholesale price movements. Early exit fees may apply.
How the Tracker Tariff Works
The Tracker tariff links your energy price directly to the day-ahead wholesale market. Each afternoon (typically after 4pm), Octopus publishes the next day's unit rate based on that day's wholesale auction. A formula adds a fixed markup to the wholesale price to cover network costs, policy costs, and Octopus's margin.
This means your rate can vary significantly day to day. During periods of low demand or high renewable generation, Tracker customers often pay well below the Ofgem cap. During cold snaps or supply constraints, rates can spike above the cap — though Octopus applies a price cap to the Tracker to limit extreme spikes.

Frequently Asked Questions
How do I sign up to Octopus and access the Tracker?
To gain access to the Tracker rates, you must:
- Ask a friend who's already with Octopus Energy for their referral link — you'll both get £50 bill credit (splitting £100 total!)
- Sign up to the Flexible Ofgem Cap Tariff
- Apply to join the Tracker
- Be a little patient (it takes a few days for Octopus to switch you over)
Do I need smart meters to join Octopus Energy?
No. You do not need smart meters to join Octopus and receive the £50 bill credit (when you use a friend's referral link). However, you need smart meters to join the Tracker tariff.
Can I get the Tracker without smart meters?
No. Smart meters are required for the Tracker tariff because Octopus needs half-hourly consumption data to bill you at daily-changing rates. You can request a free smart meter installation when you sign up to Octopus Energy — installation typically takes 2-4 weeks.
How does the Tracker compare to the government cap?
The Tracker adjusts daily based on wholesale energy prices. When wholesale prices are lower than the Ofgem price cap, Tracker rates may be lower. When wholesale prices rise, Tracker rates may be higher. Past performance is not indicative of future results.
How often do Tracker prices change?
Tracker prices change every day. Octopus typically publishes the next day's rate after 4pm GMT, based on that day's wholesale market auction. You can check tomorrow's rate on this page once it's available.
What is the Octopus Tracker tariff cap?
Octopus applies a cap to the Tracker tariff to protect customers from extreme wholesale price spikes. The cap is typically set at a level above the Ofgem price cap. If wholesale prices rise above the cap, Octopus absorbs the extra cost. The exact cap level is specified in each Tracker version's terms.
What happens when wholesale prices spike?
During wholesale price spikes (e.g. cold snaps, low wind generation, supply disruptions), your Tracker rate will increase. However, the Tracker cap limits how high your rate can go. If you're concerned about volatility, you can switch to the Flexible (Ofgem cap) tariff at any time — but note you cannot rejoin the Tracker for 9 months after leaving.
If prices go up, can I switch back to the Ofgem Cap tariff (Flexible)?
Yes. That is why I built this price tracker. 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.
Get a £50 Bill Credit with Octopus Energy
I don't work for Octopus Energy. I read about the Tracker tariff on r/beermoneyuk a few years ago and signed up. I use Octopus Energy myself and track these prices to monitor my own energy costs.
If you'd like to sign up, use a referral link and you'll both get £50 bill credit. T&Cs apply.
