Octopus finally sending out emails regarding Go tariff. In summary, no change. Excerpt below. No info on Tracker.
The Energy Price Guarantee caps the average unit rate to 34p / kWh (this number varies by region) — and with a smart time–of–use tariff, that means the combined average of your off-peak and peak rates is capped at 34p.
So although your day rate is above 34p, the Government’s rules are very clear: we can’t apply the subsidy because your night rate is so low, and overall you’re already paying less than the Energy Price Guarantee rates for your electricity.
