The Two Main Plan Types

When shopping for energy suppliers, you'll see plans labeled as either "fixed" or "variable." This is one of the most important decisions you'll make.

Fixed-Rate Plans

Your rate is locked in for the duration of the contract (typically 12-36 months). Your bill stays the same month to month (unless your usage changes).

Pros:

  • Predictable monthly bills
  • Protected if market rates rise
  • Peace of mind

Cons:

  • You miss out if rates drop
  • Usually a higher starting rate (supplier pricing in the risk)
  • Early termination fees if you want to cancel

Variable-Rate Plans

Your rate fluctuates based on market conditions, typically reset monthly. Your bill varies from month to month.

Pros:

  • Can be cheaper if rates drop
  • No early termination fees (usually month-to-month)
  • Flexibility to switch anytime

Cons:

  • Unpredictable bills if rates spike
  • Often more expensive if the market rises
  • Requires active monitoring

Which Should You Choose?

Choose Fixed if: You want predictability and don't want to think about energy shopping. You're risk-averse. You're locking in a rate that's substantially cheaper than your current rate.

Choose Variable if: You're comfortable with monthly changes. You monitor rates regularly and plan to switch if it gets too expensive. You think rates might drop and want to benefit from that.
