Understanding your energy bill

In debit vs in credit:
what your energy bill actually means

These two terms confuse a lot of people because they work the opposite way to most other bills. Here is a plain-English explanation of both.

In debit
You owe money

Your energy account is in debit when you have used more energy than you have paid for. The outstanding balance is owed to your supplier. It will usually show as a negative number, a minus symbol, or the letters DR on your bill.

"Your account is £47.20 in debit" = you owe your supplier £47.20
In credit
You are owed money

Your energy account is in credit when you have paid more than the energy you have used. The balance is yours and sits in your account with the supplier. You can request a refund at any time or leave it to offset future bills.

"Your account is £83.40 in credit" = your supplier holds £83.40 of your money
Why it happens

Why does my energy account go in debit or credit?

Most common reason for debit

Higher usage than your direct debit covers

If your monthly direct debit is set based on your previous year's usage and energy prices have risen, or you have used more than expected, your payments may not be covering the full cost. Winter is the most common time to go in debit as heating usage rises sharply.

Most common reason for debit

Estimated bills based on low readings

If your supplier has been estimating your bills using readings that were lower than your actual consumption, a large debit can build up over time and appear suddenly when an accurate reading is taken. Submitting regular meter readings or getting a smart meter prevents this.

Most common reason for credit

Direct debit set too high

If your direct debit was increased when energy prices rose but your usage stayed low, credit can build up over summer when you are using less heating. A credit balance is common in spring and early summer for households on a fixed monthly direct debit.

Also common

Tariff change mid-billing period

Switching tariff or supplier mid-year can create a credit or debit on your old account depending on when the final reading was taken and how your last direct debit was timed. Your old supplier must issue a final bill within 6 weeks of you switching.

What to do

What should I do if my account is in debit or credit?

If you are in debit: first check that your supplier has accurate meter readings. If your balance is based on estimated readings, submit an actual reading and request a corrected bill. If the debit is accurate, your supplier will usually adjust your direct debit to spread the repayment over several months. Contact your supplier if you want to agree a repayment plan rather than a sudden direct debit increase. If you are struggling to pay, ask about hardship funds or payment plans — most suppliers have them.

If you are in credit: you can request a refund from your supplier at any time. Suppliers are required to refund credit promptly on request. Many will do so automatically when the credit builds above a certain threshold. If you are happy leaving the credit in your account, it will offset your next set of bills through winter. Some people prefer to keep a credit balance as a buffer against higher winter costs.

In either case, the most effective long-term fix is to ensure your supplier always has accurate readings. Smart meters send readings automatically, eliminating estimated bills and the debit or credit swings they cause. See our smart meter guide for more.
