Understanding When You Can Claim a Refund from Your Energy Supplier

When it comes to claiming a refund from your energy supplier, it’s important to understand the situations where you might be entitled to get money back. The most common reasons for refunds include being overcharged, receiving an incorrect bill, or experiencing payment errors such as direct debits being taken for the wrong amount.

Overcharging can happen if your supplier estimates your usage incorrectly, especially if you haven’t submitted recent meter readings. Sometimes, changes in tariffs or billing periods can also lead to mistakes. Incorrect billing might involve charges for services you never agreed to, or bills sent to the wrong person or address. Payment errors could be as simple as accidental duplicate payments or your supplier failing to apply a payment you’ve made.

Because errors can be easy to miss, it’s crucial to review your energy bill carefully each time you receive one. Look out for unexpected charges, unusual usage amounts, or changes in your direct debit. If you spot anything that doesn’t look right, gather evidence such as copies of bills, payment confirmations, and meter readings. This will make it easier to explain the issue to your supplier.

Before you claim a refund, make sure you’re actually the person responsible for the bill. If you’re not named on the account, or if you share a property, you may need to check if you’re responsible for paying an energy bill. Only the account holder or someone authorised by them can usually request a refund.

As a consumer in the UK, you have clear rights when it comes to your energy bills. Energy suppliers are regulated by Ofgem and must follow strict rules under the Gas Act 1986 and Electricity Act 1989. These laws require suppliers to bill you accurately and correct any mistakes promptly. If you’ve been overcharged or billed incorrectly, your supplier must refund you the difference or adjust your account. For more detailed information on your protections and what you can expect, see our guide to know your rights regarding energy bills.

Rest assured, the process for claiming a refund is usually straightforward if you follow the right steps: check your bills, gather evidence, and contact your supplier as soon as you notice a problem. If you need further help or want to understand more about problems with your energy bill, our comprehensive resources can guide you through every stage, from spotting errors to resolving complaints.

Step 1: Check Your Energy Bill Carefully

Carefully checking your energy bill is the first and most important step when claiming a refund from your supplier. Mistakes can happen for a variety of reasons, and spotting them early can help you recover any money you’re owed.

Look for Signs of Overcharging

Start by reviewing your bill for any unexpected changes. Are the amounts higher than usual, or have you noticed a sudden increase in your charges? Compare the current bill to previous ones to spot any unusual patterns or unexplained fees. Sometimes, overcharging can be caused by estimated readings, tariff changes, or administrative errors.

Verify Meter Readings

Your bill should show the meter readings used to calculate your charges. Check these against the actual readings on your gas or electricity meter. If the readings on your bill are higher than those on your meter, you may be paying for energy you haven’t used. Likewise, if your bill is based on an estimate rather than an actual reading, it could be inaccurate. It’s a good habit to submit regular meter readings to your supplier to ensure your bills are correct.

Understand Your Tariff and Pricing

Make sure you know which tariff you’re on and what rates you should be paying. Your bill should clearly state your tariff name and the price per unit of energy. Compare these details with your contract or welcome pack to check for discrepancies. If you’re unsure about your tariff, contact your supplier for clarification. Being on the wrong tariff or not receiving agreed discounts can lead to overcharging.

What If You Haven’t Received a Bill?

If you haven’t had a bill for some time, don’t assume everything is fine. It’s important to address this promptly, as you could face a large “catch-up” bill later. Find out what steps to take if you haven’t received an energy bill in a while.

Why Billing Errors Happen

Billing errors can occur for several reasons, such as incorrect meter readings, technical issues, or delays in updating your account details. Sometimes, suppliers may estimate your usage rather than use actual readings, which can result in overcharging or undercharging. Ensuring your bill is accurate is essential, as mistakes can affect your finances and your ability to manage energy costs.

If, after checking your bill, you believe you’ve been overcharged or billed incorrectly, find out what to do next if you think you’ve been charged too much for your energy. Taking action early can help you resolve issues quickly and get any refund you’re owed.

Step 2: Gather Evidence to Support Your Refund Claim

When you believe you have been overcharged or billed incorrectly by your energy supplier, gathering clear evidence is a crucial step in making a successful refund claim. The more organised and thorough your documentation, the stronger your case will be when you contact your supplier or escalate your complaint.

Keep Copies of All Bills, Payment Receipts, and Correspondence

Start by collecting all relevant documents relating to your energy account. This includes copies of past and current bills, payment receipts, and any letters or emails exchanged with your supplier. If you have made phone calls, note down the date, time, and the name of the person you spoke with, along with a summary of the conversation. Under the Consumer Rights Act 2015, you are entitled to receive accurate bills and clear information from your supplier, so keeping a record of all communications can help demonstrate if your rights have not been upheld.

Record Meter Readings Regularly

Suppliers often estimate your usage if you do not provide regular meter readings, which can lead to inaccurate bills. To avoid this, make a habit of recording your meter readings each month and keep a log with the date and reading. If you notice a discrepancy between your readings and those shown on your bill, highlight this when making your claim. Accurate meter readings are especially important if you are on a standard variable tariff or pay-as-you-go meter, as these arrangements rely heavily on up-to-date usage data.

Take Photos or Screenshots to Document Errors

If you spot an error on your bill – such as incorrect meter numbers, charges for the wrong address, or unexplained fees – take clear photos or screenshots as evidence. For example, you might photograph your meter display to show the actual reading, or capture a screenshot of an online account statement that shows an anomaly. These visual records can help clarify the nature of the mistake and make it easier for your supplier to investigate.

Why Evidence Matters

Providing solid evidence is essential because it supports your claim and demonstrates that you have taken reasonable steps to resolve the issue. It also helps your supplier trace the problem more quickly. In line with Ofgem’s Standards of Conduct, energy suppliers are required to handle complaints fairly and efficiently, but your claim is more likely to be resolved swiftly if you present clear, organised evidence.

Organise Your Documents Clearly

To keep things simple, organise your documents in chronological order and label them clearly. Create a folder – either physical or digital – where you keep all related paperwork, emails, photos, and notes. This will make it easier to refer back to specific details if your claim is escalated or if you are asked for additional information later on.

By carefully gathering and organising your evidence, you put yourself in the best possible position to claim a refund from your energy supplier and ensure your rights as a consumer are protected.

Step 3: Contact Your Energy Supplier to Request a Refund

When you’re ready to claim a refund from your energy supplier, it’s important to contact them directly and provide all the necessary information. Here’s how to make your request as effective as possible:

How to Contact Your Energy Supplier

Most energy suppliers offer several ways to get in touch:

  • Phone: Calling your supplier’s customer service line is often the quickest way to speak to someone directly. Have your account number ready before you call.

  • Email: Many suppliers have dedicated email addresses for billing or complaints. Check your supplier’s website or your latest bill for the correct contact details.

  • Online Forms: Some suppliers provide online forms for refund or billing queries via their websites. These forms usually prompt you to enter all the required details.

Choose the method you feel most comfortable with, but remember that written communication (email or online forms) creates a record of your request.

What to Include in Your Refund Request

To help your supplier process your refund quickly, make sure your request includes:

  • Your account number and full name as it appears on your bill.

  • A clear explanation of why you believe you are owed a refund. For example, mention if you have been overcharged, billed for the wrong period, or if there was a meter reading error.

  • Evidence to support your claim, such as copies of bills, meter readings, payment receipts, or any correspondence about your account.

  • The amount you believe you are owed (if you can calculate it), or a request for the supplier to confirm the amount.

Keep Records of All Communications

Always keep copies of any emails, letters, or online form submissions you send to your supplier. If you speak to someone on the phone, make a note of the date, time, the name of the person you spoke to, and a summary of what was discussed. These records will be helpful if you need to follow up or escalate your complaint later.

Be Polite but Firm

When making your request, remain polite and professional, but be clear about what you are asking for and why. Setting out your case calmly and firmly can help your supplier resolve your issue more efficiently.

If you feel you need additional help during this process, you may be eligible for getting extra support from your energy supplier, especially if you are in a vulnerable situation.

How Long Should You Wait for a Response?

Under rules set by Ofgem, energy suppliers must respond to complaints within a reasonable timeframe – usually within eight weeks. However, many suppliers aim to resolve billing errors and refund requests much sooner, often within 10–14 days. If you haven’t heard back after this period, or if you’re unhappy with the response, you may need to escalate your complaint.

By following these steps and keeping thorough records, you’ll put yourself in the best position to secure a prompt and accurate refund from your energy supplier.

What to Do If Your Energy Supplier Does Not Resolve the Issue

If your energy supplier does not resolve your complaint about an incorrect bill or overcharge, you still have options to pursue a refund. Here’s what you should do next:

1. Escalate the Complaint Within Your Supplier

Every energy supplier in the UK must have a formal complaints procedure. If you’re not satisfied with the initial response, ask to escalate your complaint to a higher level within the company – this might be a dedicated complaints team or a manager. Clearly explain why you’re unhappy with their response and what outcome you are seeking. Be sure to follow any steps outlined in their complaints policy.

2. Keep Detailed Records

Throughout the process, keep a record of all communications with your supplier. This includes copies of emails, written letters, notes from phone calls (including dates, times, and the names of people you spoke to), and any evidence you have of the billing error. These records will be important if you need to take your complaint further.

3. Contact the Energy Ombudsman

If your supplier still doesn’t resolve the issue after eight weeks, or if they send you a ‘deadlock letter’ stating they can do no more, you can escalate your complaint to the Energy Ombudsman. The Ombudsman is an independent service that can investigate your case, and if they find in your favour, they can require the supplier to issue a refund, make an apology, or take other corrective action. You can contact the Energy Ombudsman online, by post, or by phone.

4. Further Actions if the Issue Remains Unresolved

In rare cases where even the Ombudsman’s decision does not resolve the issue, you may consider seeking legal advice or taking the matter to court. However, most disputes are resolved through the Ombudsman process. Remember, suppliers are regulated by Ofgem and must comply with rules designed to protect consumers.

5. Support and Reassurance

It’s important to know you’re not alone in dealing with energy billing disputes. There are clear steps to follow, and independent help is available if your supplier fails to act fairly. For more detailed advice on handling disputes and what to expect from your supplier, see our guide on problems with your energy bill.

By following these steps and understanding your rights under the energy supplier’s complaints procedure, you can increase your chances of a successful refund claim.

Monitor Your Direct Debit Payments

Direct debit is a common way to pay for energy, but it’s important to keep an eye on your payments. If you notice your monthly amount has increased unexpectedly, you have the right to question it. Learn what to do if your energy supplier has increased your direct debit payments without clear explanation or justification. Energy suppliers must follow Ofgem’s rules, which require them to set direct debits fairly and review them regularly.

Understand Price Changes

Energy prices can fluctuate, especially if you’re on a variable tariff. Suppliers must give you advance notice before increasing prices, and you have certain rights if this happens. For more information on your options and protections when your energy supplier has put its prices up, see the latest guidelines and advice.

Review Your Bills Regularly

Mistakes can happen, so it’s wise to check your bills each month for any unusual charges or estimated readings. Compare your meter readings with those on your bill and contact your supplier immediately if you spot any discrepancies. This helps you catch errors early and avoid larger issues later.

Get Support if You’re Struggling to Pay

If you’re finding it hard to keep up with payments, don’t ignore the problem. Contact your supplier as soon as possible – they are required by law to offer support and may be able to arrange a payment plan. If you’re specifically struggling to pay your heat network bills, there is dedicated guidance to help you manage these costs and find further assistance.

By staying informed, reviewing your bills, and making use of available support, you can take control of your energy costs and reduce the risk of future billing issues.
