Cosy Octopus vs Octopus Agile: which is better for a heat pump in 2026?

Both tariffs are from Octopus Energy and both can deliver cheap electricity for heat pump owners. But they work completely differently. Cosy gives you the same three cheap windows every day, predictably. Agile gives you 48 half-hourly prices that change daily — sometimes very cheap, sometimes expensive. The gap between the two can be hundreds of pounds a year depending on how much automation you're willing to set up.
