If you’re in credit, were billed on estimates, or think your supplier has charged the wrong amounts, start by getting your account accurate. Then compare tariffs to reduce your monthly direct debit and stop credit building up again.
Quick check: If your latest bill shows a credit balance, you can usually request it back (often by bank transfer). If you’ve moved out or switched, ensure the final bill uses correct meter readings.

Why energy bill overpayments happen in the UK
Overpayments are common with monthly direct debits, especially when prices change, your usage drops, or suppliers rely on estimated readings. A refund is usually possible when your account is in credit or when your supplier has billed incorrectly.
Estimated readings
If your bills are based on estimates rather than actual meter readings, you can be overcharged. Submitting up-to-date readings can trigger a corrected bill and a credit balance.
Direct debit set too high
Suppliers review direct debits, but changes can lag behind usage. If you consistently build credit, you can request a reduction and/or a refund (subject to account checks).
Moving home or switching
Final bills often go wrong when opening/closing readings aren’t recorded. Correct readings and dates are key to reclaiming money after you leave a property.
Tip: If you have a smart meter, don’t assume reads always reach your supplier. Check your bill for “A” (actual) vs “E” (estimated) readings and keep your own photo evidence.
Step-by-step: how to get an energy bill refund for overpayment
Most refunds follow the same pattern: confirm the balance, correct the readings, request the refund in writing, and escalate if needed. Use the steps below to keep it simple and evidence-based.
- Gather proof: latest bill(s), payment history, and photos of your gas/electricity meter readings (with date if possible). If you’ve moved, add your move-in/move-out date and tenancy completion statement.
- Check your bill type: confirm whether charges are based on estimated or actual readings. Correct readings can change your balance immediately.
- Update readings with your supplier: submit readings via app/online account/phone. For smart meters, ask the supplier to confirm whether they’re receiving reads reliably.
- Request the refund: if your account shows a credit balance, ask for a refund to your bank account. Request confirmation of the amount and timescale.
- Ask to reset your direct debit: if you’ve been overpaying, ask for a new monthly amount based on current usage and tariff. Keep a note of the calculation basis.
- If refused, raise a complaint: ask for a written “deadlock” letter or confirmation they can’t resolve. You can then take it to the Energy Ombudsman (after the required process/time).
Template message (copy/paste)
Use this in live chat or email. Keep it factual and include readings, dates and the refund request.
Subject: Request for refund of credit balance / overpayment
Hello, my account number is [XXXX]. My latest bill dated [date] shows a credit balance of £[amount] / appears to include estimated readings. Please update my account using the following readings: Electricity [reading] taken [date], Gas [reading] taken [date] (photos available). Once updated, please confirm the corrected balance and arrange a refund of any credit to my bank account. If you can’t process this, please treat this as a formal complaint and confirm next steps and timescales in writing.
How long does a refund take?
Timescales vary by supplier and payment method. Many refunds are processed within a few working days once the balance is confirmed, but it can take longer if readings need investigation, you’re on a prepayment meter, or the account is under review.
Best practice: request the refund after you’ve submitted accurate readings and your online account shows the credit. Ask for a reference number and the payment date.
UK billing protections to know (including back-billing)
If your supplier has billed incorrectly, UK households have protections. The details depend on circumstances, but these pointers help you ask the right questions and avoid paying more than you owe.
| Scenario | What it can mean | What to do |
|---|---|---|
| Credit balance on account | You may be able to have excess credit refunded, especially if the account is accurate and your direct debit is set appropriately. | Submit readings, ask for refund and new direct debit amount, request confirmation in writing. |
| Estimated billing appears too high | Incorrect estimates can inflate charges and direct debit amounts. | Provide photo reads, ask for rebill and updated statement of account. |
| Back-billing (late bills) | If you haven’t been correctly billed for energy used more than 12 months ago in certain situations, you may not have to pay those older charges (rules and exceptions apply). | Ask the supplier to confirm how back-billing rules apply to your account and to provide a full breakdown. |
| Final bill after moving/switching | Wrong opening/closing reads can create false debt or hide a refund. | Submit opening/closing reads with dates, request corrected final bill and refund of any credit. |
Important: Rules can vary based on whether you had access issues, whether you provided readings when asked, and the supplier’s billing history. If you’re unsure, keep your request focused on (1) correcting readings and (2) confirming the accurate balance before disputing older charges.
Common mistakes that delay an energy refund
Requesting a refund before the account is accurate
If your balance is based on estimated reads, the supplier may pause the refund. Submit readings first and ask for a corrected bill, then request the refund.
Not keeping a paper trail
Phone calls are easy to lose. Follow up by email or live chat transcript and keep dates, names and reference numbers.
Forgetting the direct debit reset
Even if you get your credit refunded, you can rebuild credit quickly if the monthly payment stays too high. Ask for a recalculation.
Switching mid-dispute without saving evidence
Switching is often fine, but take meter photos, download bills, and keep your account screenshots before closing access to your old supplier portal.
Energy bill refund FAQs (UK)
Can my supplier refuse to refund my credit?
They may delay or refuse if they believe the balance isn’t confirmed (e.g., estimated reads), if a bill is under dispute, or if they consider the credit needed to cover upcoming charges. Ask them to explain the reason in writing and to confirm what’s required to release the refund.
Will I get a refund automatically after switching?
Not always. You’ll usually receive a final bill. If it shows credit, request repayment and provide your forwarding address/bank details where needed. Keep closing reads and dates.
I’m on a prepayment meter — can I still be in credit?
It’s less common, but issues can happen (especially with tariff changes, meter faults, or account corrections). Ask for a full statement and what method they use to return any overpayment.
What if I can’t access the meter for readings?
Tell the supplier why (e.g., flats with locked cupboards). Ask for next steps, such as an arranged read or guidance for your building manager. Keep written records so estimates don’t persist without challenge.
Do I have to accept a higher direct debit to get a refund?
If your supplier says they need to hold credit for “future usage”, ask them to provide the calculation and to reassess based on your current usage and tariff. It’s reasonable to request both a fair direct debit and a refund of excess credit.
When should I go to the Ombudsman?
If you’ve made a formal complaint and it isn’t resolved within the required process/time, or you receive a deadlock letter, you may be able to escalate. Ask your supplier for their complaint reference and confirm escalation options.
