What types of energy plans are available?

There are several plan types and rate structures you’ll encounter when searching for a plan. The most common options are fixed rate and variable rate plans.

• Fixed rate. With a fixed rate plan, the rate you pay for electricity will stay the same throughout your contract and will not change based on fluctuations in the energy market.
• Variable rate. With a variable rate plan, your rate will change based on the market. This means you could pay a lower rate when demand is low but may be hit with a higher price when the energy supply is low.

There are other rate structures within these plan types. It’s important to note that not all fixed or variable rate plans are the same. For a more detailed look at navigating plan types, see our guide.

Do you run a credit check?

Yes. Credit checks are a normal part of the energy buying process. Most providers require a credit check before they will offer you service. If you wish to avoid a credit check, a prepaid electricity plan might be the best option, although the rates may be more expensive.

Will I have to pay a deposit?

Possibly. Providers may require a deposit based on your credit score. If you pass the credit threshold set by a provider, you may not need to pay a deposit. When you select a plan, we’ll let you know if a deposit is required to begin service. If you’re searching for a no-deposit option, prepaid plans are a popular choice. See our deposits page for more information on these options.

What if I am moving?

If you are planning to move, you can choose to remain with your current provider or switch to a new provider with no early termination fee. If you decide to switch, you can shop for a new provider up to 90 days before you move. Most homes have smart meters installed, meaning you won’t need to arrange a technician visit. Learn more on our moving page.

What do I do if I want to switch providers?

Switching to a different provider is easier than it may seem. However, if you have a fixed rate plan, it’s important to be aware of your early termination fee. Variable plans typically allow customers to switch at any time without an extra cost. If your plan is about to end, you can switch to a new provider up to 14 days before the contract expires without early termination fees. For more information, see our guide to switching.
