Octopus Tracker sets one electricity rate for the entire day, based on the previous day's wholesale electricity price plus a fixed Octopus margin. The rate is published by 11pm for the following day. Your smart meter records your total daily usage and you're billed at that single rate.
Why Tracker is simpler than Agile
No half-hourly slots to manage. No peak pricing to avoid. One rate, all day. If wholesale prices are low, your rate is low. If wholesale prices spike, your rate follows — but with a one-day lag, so you know what you'll pay before the day starts.
When Tracker saves money
Tracker typically saves 5–10% versus the standard tariff over a full year. The saving is less than Agile's 10–15% because you can't arbitrage cheap overnight slots — your rate is the same whether you use electricity at 3am or 3pm.
Tracker performs best when wholesale prices are trending downward or stable. During sustained wholesale price spikes (like the Iran war period in early 2026), Tracker rates can temporarily exceed the standard cap.
Who should use Tracker
- Households who want cheaper bills without timing their consumption
- People who don't have batteries or solar panels
- Anyone who finds Agile's half-hourly complexity off-putting
