The Cosy tariff
Half-price electricity when your heat pump is working.
Octopus Cosy offers dramatically cheaper electricity during two daily windows — typically 4am-7am and 1pm-4pm — exactly when heat pumps warm your fabric and pre-heat hot water most efficiently.
- Two cheap windows daily — cuts unit rate by ~40% in those hours
- Can reduce heat pump running costs by 25–30% vs standard tariffs
- Free smart meter install if you don't have one
- No exit fees — switch back any time
- Available to existing heat pump owners, not just new installs
Our recommendation
We integrate Cosy into your install.
Smart controls programmed to pre-heat during cheap windows. Weather compensation tuned to push load into off-peak. It's set up once and runs itself.
