Direct Debit vs Paying On Receipt Of Bill
How you pay for your energy changes how much you pay. The two main options for UK households are monthly Direct Debit and paying on receipt of bill (standard credit). Here's how they compare and which one usually works out cheaper.
The quick answer
For most households, fixed monthly Direct Debit is the cheapest way to pay. Suppliers reward it with lower unit rates because it's predictable and cheap to administer. Paying on receipt of bill gives you more control and only charges you for what you've used — but you'll usually pay a premium for the privilege, and the Ofgem price cap sets a higher cap for standard credit.
Direct Debit
- Lowest unit rates and standing charges
- Predictable, smoothed monthly cost
- Nothing to remember — it's automatic
- Can build up large credit balances
- Payments based on estimates if no meter reads
On receipt of bill
- Pay only for energy you've actually used
- No credit balance tied up with the supplier
- Full control over when you pay
- Higher unit rates — often £100+/yr more
- Big winter bills land in one lump
Why Direct Debit is usually cheaper
Direct Debit gives suppliers reliable, predictable income and removes the cost of chasing late payments. Ofgem's price cap reflects this by setting a lower allowed rate for Direct Debit customers than for those paying on receipt of bill or using prepayment. The gap is real money: on a typical dual-fuel home it commonly works out at well over £100 a year.
When paying on receipt can make sense
- You want to avoid handing the supplier a credit balance.
- Your usage is very irregular and hard to smooth into monthly amounts.
- You prefer to pay strictly for what you've used, when you've used it.
Whichever method you choose, give regular meter readings (or use a smart meter) so your payments reflect reality. Learn how to read your energy bill and check whether your monthly amount is fair.
