Octopus Heat Pump Tariff

Octopus Heat Pump Tariff

If you are searching for an Octopus Heat Pump Tariff, the honest answer is that there is not just one option. Octopus Energy offers several tariffs that can work well with heat pumps, and the best choice depends heavily on the kit you have and how your home runs day to day.

Before going too deep into tariffs, it is worth making sure your system is performing as expected. If your heat pump is not running efficiently, no tariff will fully fix the running costs. I explain what good looks like in my guide here: Heat Pump Performance for Normal People.

Some households benefit most from a dedicated heat pump style tariff like Cosy. Others can do better using time of use tariffs, especially if they also have solar, battery storage, or an EV in the mix.

Below is a quick guide to the main routes, and where to dig deeper.

Octopus Cosy

The closest thing to a purpose built Octopus heat pump tariff today is Octopus Cosy. It is designed around typical heat pump usage patterns, with cheaper electricity available in set low price windows.

In short:

• Three low rate windows spread through the day

• A higher peak period to discourage heavy use

• Works well for homes running steady low temperature heating

• Particularly useful if you do not have a battery to shift load

Cosy can be a strong “fit and forget” option for many heat pump households. That said, it is not always the cheapest once you start adding flexibility into the mix.

Very high level guidance:

Heat pump only (no battery, no EV)
Cosy is often the simplest and safest starting point.

Heat pump plus battery
Time of use tariffs like Agile or Go style products can sometimes beat Cosy because you can shift consumption into cheaper periods.

Heat pump plus solar and battery
This is where things get interesting. With the right control strategy, dynamic tariffs can materially outperform fixed window tariffs.

Heat pump plus EV
Intelligent Go and similar EV tariffs may be worth modelling, especially if overnight charging aligns with your heating demand.
