Heat Pump Tariffs UK
Searching for the best heat pump tariffs UK homeowners can use? You are in the right place. As more properties move to electric heating, the electricity tariff you choose now plays a major role in overall running costs.
There is no universal winner. The most suitable heat pump tariff depends on how your system operates, how flexible your household demand is, and whether you have extras like solar, battery storage, or an EV.
Before getting deep into tariff comparisons, it is worth confirming your heat pump is performing efficiently. If the system is not running well, even the cheapest tariff will struggle to deliver good results. I explain what to look for here:

Below is a practical overview of the main tariff approaches used by UK heat pump owners.
Heat Pump Performance for Normal People
Octopus Cosy
For many UK households, Cosy from Octopus Energy is one of the first tariffs considered for heat pumps. It is structured to better match typical low temperature heating patterns compared with standard flat rate tariffs.

Where Cosy tends to work well:
-
Homes running steady background heating
-
Properties without battery storage
-
Households wanting predictable pricing
-
Users who prefer a low touch setup
Cosy can be a solid “set and leave” option. However, once you add flexibility through storage or load shifting, other tariffs can sometimes come out ahead.
How to Choose the Best Heat Pump Tariff in the UK

General rules of thumb:
Heat pump only
A structured tariff like Cosy is often the simplest place to begin.
Heat pump plus battery
Time of use tariffs become more attractive because you can shift consumption into cheaper windows.
Heat pump plus solar and battery
Dynamic tariffs may offer the lowest annual cost if you are comfortable with more active optimisation.
Heat pump plus EV
EV tariffs like Intelligent Octopus Go can work well in some cases, especially where overnight usage is high.
Key Takeaway
When reviewing heat pump tariffs UK wide, the best choice depends less on the tariff name and more on how your home behaves.
Focus first on:
-
good heat pump performance
-
understanding your daily load profile
-
how much demand you can shift
-
how hands on you want to be
Start simple if needed, then refine once you have real usage data to work with.
