What split billing is
Split billing means the household’s charges (including energy) are apportioned between named residents. Your amount can differ from your housemates’ when your responsibility dates or included services differ, or when there have been mid-cycle changes.
This article focuses on energy. Other Bunch products (e.g., broadband) may also be split and can affect totals if they’re included in your package.
Why amounts can be different
1) Different start/finish dates (pro-rata)
If someone moves in or out mid-month, they’ll only be charged for the days they’re responsible for.
2) Changes to the services included
If a resident adds/removes a service (e.g., energy added to their package later), their share changes from that date. We’ll confirm any update on the next invoice.
3) Usage reviews and end-of-term true-up
Energy is billed against a yearly allowance on fixed tariffs. If the property’s usage ends over/under the allowance, a final true-up is calculated for the property and then apportioned fairly using recorded occupancy dates (and any agreed share settings).
4) Supplier switch timing
During a switch to or from Bunch, billing responsibility changes on the official takeover date. If residents have different move-in dates around a switch, their billed periods can differ.
5) Corrections or credits
Occasionally we issue adjustments (e.g., to correct dates, apply a credit, or fix an address/meter mismatch). Adjustments may apply to one person’s account if it relates to their responsibility period only.
6) Standing charges vs usage
Standing charges accrue daily regardless of use; unit rates depend on kWh consumed. Two people with different billed days will see different totals, even if the unit rates are the same.
How to check your share
Open your Bunch Portal and compare the charge dates on your invoice with your move-in/move-out dates.
Check the Services section for anything added/removed recently.
For energy, make sure your latest meter readings are showing. If not, submit them.
When to contact us and what to send
Contact us if something doesn’t add up. To help us resolve it quickly, please include:
Your move-in/out dates (and any changes agreed with the household).
The invoice number(s) you’re querying and a brief note of what differs.
For energy queries: your latest meter readings and a clear meter photo showing the full meter face and serial number.
Snippet: Send a clear meter photo (full face + serial).
If another supplier is involved (e.g., you’ve received a bill covering the same dates), see Bills from other suppliers during a switch or move.
FAQs
Do housemates always pay equal shares?
Shares are based on recorded responsibility and the services included. If those differ, totals will differ. We’ll state the dates and any changes on your invoices.
Can I change my share mid-contract?
Tell us what needs changing (e.g., a resident moving out). We’ll update from the effective date and confirm any pro-rata adjustment on the next invoice.
Why did my amount go up when my housemate’s went down?
Often caused by a service change or an adjustment correcting the responsibility window. Check your invoice dates and the Services section first.
