Tariff
Cosy Octopus: the heat pump tariff, and whether it suits you
Cosy Octopus gives several cheap electricity windows spread through the day, designed around heat pumps running in bursts rather than one overnight block.
| Best for | Heat pump households, and homes with storage heaters or a home battery. |
| You need | A smart meter. Ideally a heat pump or thermal store to shift heat into. |
The catch
The rate outside the cheap windows is higher than standard. Without something that stores heat, you pay the peak more often than you use the cheap window.
