Good Energy launched a fixed heat pump tariff in November 2024, with an off-peak rate of 10p per kWh, according to a guide to battery tariffs published by Sunsave Energy1. The guide states that the tariff has been available "ever since its launch in November 2024" and that its "10p per kilowatt-hour (kWh) off-peak rate has risen to 14p per kWh since then"1. The development summary records the tariff as open to all households.
The same guide lists the Good Energy Heat Pump tariff in a comparison table of eight tariffs, with an off-peak rate of 14p per kWh, a peak rate of 30.69p per kWh, a standing charge of 57.39p per day and estimated annual savings of £3261. The off-peak periods are given as 5am to 9am and 1pm to 4pm1. The table's savings figures are modelled on a home with a 10kWh battery using 3,400kWh per year, switching from the July 2026 energy price cap, and assume 85% of electricity is imported at the off-peak rate and 15% at the day or peak rate1.
The guide's comparison places the Good Energy tariff sixth of the eight listed, behind British Gas Store&Reward at 22p per kWh all day, British Gas Store&Save at 11p per kWh all day, 100green Tide Smart at 7.43p per kWh between 12am and 7am, EDF Empower Fixed at 10.361p per kWh between 1am and 4am, and 100green Tide Lifestyle at 15.75p per kWh across three windows1. It sits ahead of British Gas Charge Power at 14.963p per kWh and Octopus Agile Octopus, whose average import rate between 6 July 2025 and 5 July 2026 was 18.17p per kWh1.
The guide describes the two British Gas tariffs as available only to Sunsave Home Battery customers, and states that eligibility requires being a homeowner aged 18 to 75, not having solar panels, an EV charger or a heat pump, and using between 3,100kWh and 4,500kWh of electricity per year1. No equivalent eligibility restrictions for the Good Energy tariff are reported1. The guide does not give the length of the Good Energy fix, its exit fee, or whether it remains open to new customers1.

Why it matters for households
A heat pump runs on electricity, and how much a household pays for that electricity depends on when it is used. A tariff with defined off-peak windows lets a heat pump and a hot water cylinder run at the cheaper rate, with the rest of the day's demand met at the peak rate. On the figures listed, the gap between the Good Energy off-peak rate of 14p per kWh and its peak rate of 30.69p per kWh is more than double, so the share of consumption that falls inside the two windows drives the bill1.
The comparison table's £326 annual saving is modelled for a home with a 10kWh battery, not for a heat pump alone, and assumes most electricity is imported off-peak1. A household without a battery cannot shift demand in the same way, so the saving depends on how much of its heating and hot water can be scheduled into the 5am to 9am and 1pm to 4pm windows1. The standing charge of 57.39p per day applies regardless of usage1.
For energy independence, a time-of-use tariff changes the value of running appliances and heating at particular hours, and rewards a household that can store or defer demand. The guide notes that the Good Energy off-peak rate has risen from 10p to 14p per kWh since launch, which shows that the terms of a fixed tariff are not permanent1.
What happens next
No dated next steps for the Good Energy heat pump tariff are reported1. The guide states that it will be updated regularly as energy companies change their tariffs or introduce new ones1.
