Billing Cycle
Key takeaways
- Your billing cycle is how often the supplier issues you a bill — usually monthly or quarterly.
- Half-hourly sites typically get monthly bills against actual consumption data.
- Cycles based on estimated readings can drift from reality — submit actual readings to keep bills accurate.
What is a billing cycle?
A billing cycle is the regular interval at which your energy supplier produces and issues a bill for your gas or electricity usage. Common cycles for UK businesses are monthly, quarterly and (for larger sites) monthly against half-hourly data.
The cycle affects your cash flow and the accuracy of each bill — a longer cycle with estimated readings can swing significantly when an actual read finally lands.
Common cycles
- Monthly — typical for direct-debit microbusiness contracts and most half-hourly sites.
- Quarterly — common for smaller business sites on traditional metering.
- Bi-monthly / customer-defined — some flexible contracts allow custom cycles.
Keeping bills accurate
Submit actual meter readings ahead of each billing date, or fit a SMETS2 / AMR meter so readings are sent automatically.
If a bill looks wildly out of line with usage, request a re-bill and check whether you’re on a profile class or load profile that no longer fits how you actually consume energy.
