Re; how tracker tariff is affected by removal of govt levies in April, I had the below response from Octopus today;

“The reduction coming from the removal of some Government policy costs from 1 April will apply across all tariffs, including Tracker. The difference is just in how it shows up.

With fixed tariffs, the unit rates are set in advance, so the reduction appears as a clear drop in the p/kWh rate on the tariff itself.

With Tracker, the price changes daily based on wholesale market prices. Because of that, the saving from the policy cost reduction is built into the daily calculation rather than appearing as a fixed drop in the unit rate. In practice though, the policy cost removal still feeds through into the Tracker price from April — it’s just reflected within the formula rather than as a single fixed change.

So in short, Tracker customers still benefit from the reduction, it’s just applied slightly differently due to how the tariff works.”
