Octopus Energy Heat Pump Tariff

Octopus Energy Heat Pump Tariff

If you are specifically looking for an Octopus Energy heat pump tariff, you are already asking the right question. Running costs for a heat pump are driven not just by system efficiency, but by the electricity tariff sitting behind it.

Octopus does not offer a single one size fits all heat pump tariff. Instead, there are several smart tariffs that can work well, depending on your setup and how flexible your home is.

Before focusing purely on tariff choice, it is worth checking your system performance is in the right ballpark. If the heat pump is working harder than it should, even a well matched tariff will struggle to deliver the savings you expect. I walk through the key checks here:

Why Cosy is popular with heat pump owners:

Cosy works well as a low hassle starting point. However, it is not automatically the cheapest once you introduce more flexibility into the home.

Time of use tariffs can start to pull ahead because you can shift consumption into cheaper periods.

Heat pump plus solar and battery
Dynamic tariffs may offer the lowest annual cost if you are willing to optimise and automate.

Heat pump plus EV
EV focused tariffs such as Intelligent Go can be worth modelling, particularly for overnight heavy users.
