What is a Direct Debit?
A Direct Debit spreads the cost of your energy across the year, helping you pay the same amount each month.
Instead of paying higher bills during winter and lower bills during summer, we estimate your yearly energy costs and divide them into monthly payments.
Your payments are collected automatically from your bank account and are protected by the Direct Debit Guarantee.
Why do energy suppliers use Direct Debit?
Direct Debit helps smooth out seasonal changes in energy use.
Most homes use more gas and electricity during winter. By spreading payments across the year, you can budget more easily and avoid unexpected seasonal bills.
How do you calculate my Direct Debit?
We calculate your Direct Debit using:
Your energy use
Your current account balance
Your energy prices
How much energy we expect you’ll use over the next year
How can I make sure my payments are covering the energy I use?
The more accurate your meter readings are, the more accurate your Direct Debit will be. So, it’s important to provide us with your meter readings regularly.
If you have a smart meter, we’ll automatically receive regular readings. If you don’t already have a smart meter, find out more and book an installation here.
How is my monthly payment worked out?
Step 1: We calculate your energy costs
We look at:
The energy you’ve already used
The energy you are likely to use over the next year
Step 2: We work out the total amount you need to pay for the year
We combine:
Your account balance as it is at the moment
Your estimated future energy costs
Step 3: We spread the cost across the year
We divide the total amount by 12 to create a monthly payment.
Step 4: We adjust for upcoming payments
If your next Direct Debit is due within the next two weeks, we’ll usually collect it at the current amount.
We’ll then spread any remaining balance across your future monthly payments.
Why has my Direct Debit changed?
Your Direct Debit may increase or decrease if:
Your energy use changes
Energy prices change
You change tariff
You build up debt on your account
You build up more credit than expected
We receive updated meter readings

How often will I receive a bill?
If you pay by Direct Debit, we’ll send you a bill summary at least twice a year.
Your bill shows:
How much energy you’ve used and how much it’s cost
Any account balance
Your current Direct Debit amount
If your bill is based on estimated readings, please send us an up-to-date meter reading so we can make sure you’re paying for the energy you’ve actually used.
How can I make sure my monthly payments are right?
You can use My Energy Tracker in your online account or the ScottishPower App to see whether you’re using more or less energy than we expected. You can then choose to use less energy or change your monthly payment.
Our Direct Debit Manager tool can also help as you can:

Can I get a refund if I'm in credit?
Yes.
It’s normal to build up credit during the warmer months when many households use less energy. This credit should help cover higher winter energy use. We use any credit on your account to lower your monthly payments.
If you’d like a refund:
- Log in to your online account
Submit an up-to-date meter reading
We’ll check whether your account is eligible
If you’re eligible, contact us through webchat and we’ll help you arrange the refund.
