Octopus Tracker regional prices vary because each DNO region has its own costs. That means the daily unit rate and standing charge in London may differ from those in the North West.

How the Octopus Tracker Tariff is Calculated
The Octopus Tracker tariff is built on wholesale market data. Each day’s unit rate reflects the day-ahead auction price (N2EX for electricity, Marex Spectron for gas), plus the usual non-wholesale costs:
-
Network charges (DUoS, TNUoS)
-
Balancing costs (BSUoS)
-
Policy levies (environmental & social obligations)
Because it follows wholesale movements, Tracker can deliver noticeable savings when market prices fall — but it also exposes you to short-term spikes. To protect customers, a Price Cap Protect limit applies (100p/kWh for electricity, 30p/kWh for gas).
Octopus Energy outline the full Tracker tariff formula on their official Tracker FAQ page — look for the section “How is the daily unit rate for Octopus Tracker calculated?”

What to Consider Before Switching
-
Daily price changes – The wholesale market is volatile, so your Octopus Tracker daily rates can rise or fall every day.
-
Price Cap Protect limits – The tariff has an internal cap (100p/kWh electricity, 30p/kWh gas), but it can still be higher than the Ofgem price cap at times.
-
Standing charges – Your Octopus Tracker standing charge is fixed for your region and typically reviewed every three months.
-
Smart meter required – You’ll need a working SMETS2 (or certain SMETS1) smart meter that sends half-hourly readings.
-
Commitment rules – It’s a 12-month term with no exit fees, but if you leave, you can’t rejoin for 9 months.
-
Active management – This is not a “set and forget” tariff. It works best if you monitor daily updates and plan high-use activities on cheaper days.
-
Historic context – Check the graphs and Octopus Energy Tracker price history on this page to see how rates have moved compared to other tariffs.
