Octopus Tracker explained: is daily wholesale pricing right for your heat pump?

Octopus Tracker prices your electricity differently every day, following the wholesale market rather than a fixed quarterly rate. On most days it comes in below the Ofgem cap.

Economy 7 and heat pumps: why it usually isn't the right tariff in 2026

That mismatch, combined with Economy 7's high daytime rate, means most heat pump households end up paying more on E7 than they would on a modern time-of-use tariff.

Fixed vs variable tariffs for heat pump owners: which gives a lower bill in 2026?

Most fixed vs variable comparisons assume a typical household with flat usage. Heat pump owners are not typical — they use two to three times more electricity than average, most of it in winter, and a significant share is shiftable to off-peak windows. That changes the calculation considerably. A flat fixed rate competes not with the standard cap, but with the effective blended rate you'd actually achieve on a time-of-use tariff.
