The typical wait for a final energy bill is 6 to 8 weeks
When you switch supplier or close an account, you need a final bill to settle your balance. Ofgem data from 2026 shows the average final bill is issued within 6 to 8 weeks of a switch or account closure (Ofgem, 2026). This is the standard window set by industry rules, though some suppliers complete it in 4 weeks.
A final energy bill typically takes 6 to 8 weeks to arrive after switching or moving. Smart meters can cut this to 4 to 6 weeks. The wait depends on your meter reading method and supplier processing.
- Wait 6 to 8 weeks for a final bill after switching suppliers.
- Smart meters cut the wait to 4 to 6 weeks with automatic readings.
- Moving home also takes 6 to 8 weeks after the move-out reading.
- If your supplier goes bust, expect 8 to 12 weeks for reconciliation.
- Your final bill differs from your closing balance; check both figures.
- The typical wait for a final energy bill is 6 to 8 weeks
- Quick numbers typical timelines for final bills
- Your final bill is not the same as your closing balance
- How long for final energy bill after switching suppliers
- How to verify your final bill is correct
- What to do if your final bill is delayed or incorrect
- Eligibility and certification for meter reading disputes
The clock starts from the date of the final meter reading, not the date you request the switch. If a smart meter is present, the process can be faster because readings are automatic. A manual reading submitted by the homeowner takes longer to validate.
Quick numbers typical timelines for final bills
| Scenario | Typical time to final bill | Notes |
|---|---|---|
| Standard switch (manual read) | 6 to 8 weeks | Depends on the supplier sending a final statement. |
| Switch with smart meter | 4 to 6 weeks | Automatic readings speed up validation. |
| Moving home | 6 to 8 weeks | Final bill issued after the move-out reading. |
| Supplier goes bust | 8 to 12 weeks | New supplier must reconcile past usage. |

Your final bill is not the same as your closing balance
The final bill is the statement of actual usage for the period up to the switch or move. The closing balance is the amount you owe or are owed after payments. These are different figures.
The final bill may include adjustments for estimated readings, standing charges, or direct debit corrections. A closing balance might appear before the final bill is issued, causing confusion. For example, your old supplier might show a credit balance on your online account, but the final bill could adjust that amount if readings were estimated (Ofgem, 2026).
How long for final energy bill after switching suppliers
For a standard switch, the final bill from your old supplier arrives within 6 to 8 weeks of the switch date. The switch itself takes up to 5 working days to transfer, after which the old supplier has 6 weeks to issue the final bill (Ofgem, 2026).
If you do not receive a final bill within 8 weeks, you should contact the old supplier directly. Citizens Advice recommends keeping a record of your meter reading on the switch date to help resolve any delays (Citizens Advice, 2026).
How to verify your final bill is correct
Check the final reading against the one you submitted or the smart meter data. If they match, the usage calculation is likely correct. Cross-check the tariff’s unit rates and standing charges against your original contract.
Ensure that any exit fees or early termination charges are correctly applied, if applicable. If the bill seems wrong, you have 12 months to raise a formal complaint (Ofgem, 2026). Keep copies of all correspondence and meter readings.
What to do if your final bill is delayed or incorrect
If the bill has not arrived after 8 weeks, contact the old supplier in writing. If the supplier does not respond within 8 weeks, escalate to the Energy Ombudsman (Energy Ombudsman, 2026).
For incorrect bills, provide the correct meter reading and ask for a revised statement before paying. You are not required to pay a disputed amount until the issue is resolved, but you must pay the undisputed portion (Citizens Advice, 2026).
Eligibility and certification for meter reading disputes
If there is a dispute over the final meter reading, the supplier must follow the Balancing and Settlement Code (BSC) rules. The BSC sets the process for correcting meter readings across the industry (Ofgem, 2026).
The homeowner can request a site visit from an independent meter operator, but this is rare and only for unresolved disputes. For smart meters, the data is considered definitive unless proven faulty. You can request a data check from the Data Communications Company (DCC) (DCC, 2026).
