What this covers (and why it happens)
It’s normal to see bills from another energy supplier during a switch or when moving in/out. Common situations:
Final bill from your previous supplier
They bill you up to the takeover date (the day Bunch becomes your supplier).
Switch pending (we haven’t taken over yet)
Until the switch completes in the national energy database, your old supplier remains responsible and will bill for that period.
New tenancy / “previous occupier” bill
If you’ve just moved in, the previous occupier’s supplier may bill you for energy used from your move-in date until your chosen supplier (Bunch or otherwise) takes over.
Address or meter mismatch (MPAN/MPRN)
If the meter is linked to the wrong flat/serial number on the national database, the wrong supplier may keep billing you.
Direct debit not cancelled
Your previous supplier may continue to collect a DD until their account is finalised.
We’ll never bill you for energy before Bunch officially takes over your supply. Before takeover, your previous supplier (or the existing supplier at move-in) is responsible for billing.
What to do
A) You’re switching your energy to Bunch
Check the bill dates
If the dates are before Bunch’s switch date → this is your previous supplier’s final bill.
If the dates are after Bunch’s switch date → go to Resolve overlaps below.
Send us evidence (so we can verify the handover)
Switch-date meter reading (on/around takeover).
Clear meter photo showing the full meter face and serial number.
If requested: a recent bill or tenancy document.
Pay/settle the correct supplier
Pay your previous supplier up to the switch date.
From the switch date onward, Bunch bills you.
B) You’ve just moved in
Identify the current supplier (the one billing you is usually correct).
If unsure, see Find and contact your current energy supplier.
Send us evidence if you’re joining Bunch
Move-in date and move-in reading.
Meter photo with serial number.
Any tenancy proof we request.
Expect a “deemed” bill from the existing supplier
You’re liable from your move-in date until your new supplier (Bunch) takes over.
Resolve overlaps or wrong-supplier bills
Use this if a bill looks wrong (e.g., it charges you after Bunch’s takeover date):
Check the charge dates carefully.
Provide your switch-date reading to both suppliers.
Share your meter serial number (photo) to confirm the correct MPAN/MPRN.
Ask the other supplier to re-bill to the correct end date (the day before Bunch’s takeover).
Tell us if they need confirmation — we can verify the takeover date and opening read via industry data.
If a supplier claims different readings, ask for a reading dispute/reconciliation using your dated photo and the switch-date reading.
Who to contact (and who we can’t contact)
You need to contact any previous/other supplier directly — we’re not the account holder for their contract, so they won’t discuss your account with us.
We’ll help by confirming takeover dates and opening/closing readings from the national database and by telling you exactly what to ask the other supplier to correct.
What we’ll ask you for (so we can help quickly)
Switch-date or move-in meter reading.
Clear photo of the meter with the serial number visible.
Tenancy start date (if you’ve just moved in).
A copy of the bill you’ve received from the other supplier (with the charge dates visible).
Liability and timelines (at a glance)
Occupier liability: You’re responsible for energy from your move-in date until your chosen supplier takes over.
Final bills: Your previous supplier bills up to takeover; Bunch bills from takeover onward.
Switch timing: If an objection or address mismatch delays the switch, your previous/existing supplier continues to bill until the issue is fixed.
