A quick checklist for understanding your bill balance

What does “in credit” mean?

Being “in credit” means you have paid more to your energy supplier than the value of the energy you have used. In simple terms, your supplier owes you money. This is common if you pay by fixed DD, especially during months when your energy usage is lower.

Why your account may be in credit

Credit often builds up when your monthly payments are higher than your actual usage. This usually happens during warmer months when heating is used less, but payments remain the same. Overpayments, estimated bills, or changes in usage can also lead to being in credit.

Is being in credit a good thing?

Having some credit can be helpful, as it can cover higher energy usage during winter months. However, a large credit balance means your money is sitting with your supplier instead of in your bank account. It’s important to review your balance regularly and decide whether to keep it as a buffer or request a refund.

When to request a refund

If your credit balance is higher than needed, you may be able to request a refund from your supplier. This is especially common during summer when usage is lower.

Common mistakes to avoid

Many customers build up unnecessary credit simply by not reviewing their account regularly. Not submitting meter readings can lead to inaccurate estimates, and ignoring your balance may result in too much money being held by your supplier. Staying engaged with your account helps avoid these issues.
