How Does Cosy Octopus 12M Fixed Work?

- Fixed Rates for 12 Months: Enjoy the security of knowing your unit rates and standing charge are locked in for a full year. This protects you from potential market fluctuations and helps you budget effectively.
To take advantage of Cosy Octopus 12M Fixed, you'll need a compatible smart meter that can send half-hourly readings to Octopus Energy. This enables accurate billing and ensures you benefit from the cheap rate during your designated hours.

Potential Drawbacks to Consider
While Cosy Octopus 12M Fixed offers fantastic advantages, it's important to be aware of a couple of points:

- Exit Fee: If you decide to leave the tariff before your 12-month fixed term is up, a £50 exit fee will apply. This is a standard feature of many fixed tariffs across the industry.
- Smart Meter Essential: You'll need a working smart meter that sends half-hourly readings to fully benefit from the tariff's structure.

Is Cosy Octopus 12M Fixed Right for You? Comparison Tips
