Overcharges on your energy bill can stem from various issues, often due to errors in billing, meter readings, or contract application. Understanding these common pitfalls is the first step to identifying if you have been incorrectly charged.
Estimated bills and inaccurate meter readings
Energy suppliers often rely on estimated readings if they do not receive regular actual meter readings. These estimates are based on past usage and can be inaccurate, leading to higher bills than your actual consumption. Smart meters are designed to reduce estimated billing, but issues can still lead to overcharges if they go offline or fail to send data correctly. While online smart meters send readings automatically, manual readings are still a good practice for non-smart meters or if your smart meter is offline.
Incorrect tariffs or contract terms
You might be on the wrong tariff, or your supplier could be applying incorrect unit rates or standing charges. This can happen if your contract details were entered incorrectly, or if you were moved to a default tariff without proper notification after a fixed term ended. Always check your tariff against your contract.
Back-billing and old debt
Sometimes, suppliers realise they have not charged you for energy you have already used. This is known as back-billing. However, strict rules protect consumers from being charged for very old unbilled energy.
Faulty meters or billing system errors
Less commonly, a faulty meter might be recording usage incorrectly, or there could be a systemic error in your supplier's billing software. While rare, these issues can lead to significant discrepancies.
Spotting an overcharge requires a careful review of your energy bill. Knowing what to look for can help you quickly identify discrepancies.
Understanding your bill components
Your energy bill breaks down your charges into several key components: unit rates (pence per kilowatt-hour, or kWh), standing charges (a daily fixed fee), VAT, and your consumption period. Familiarise yourself with these sections to ensure they align with your understanding and contract.
Verifying meter readings and usage data
Compare the meter readings on your bill with your own records. If your bill uses estimated readings, check if they are significantly higher than your actual usage. If you have a smart meter, ensure it is sending readings regularly and that these are reflected on your bill. The average UK home uses around 2,500 kWh of electricity per year, according to Ofgem's medium typical domestic consumption values (TDCV) effective from 1 July 20261. This can serve as a benchmark for typical consumption.
Checking your tariff and contract details
Confirm that the unit rates and standing charges on your bill match your current tariff and contract terms. Look for any unexpected changes or charges that do not seem to apply to your agreement.
Reviewing payment history and account balance
Examine your payment history to ensure all payments have been correctly applied. Check your account balance for any outstanding amounts or credit that do not add up. Sometimes, an overcharge can simply be a misallocated payment.
If you suspect an overcharge, you need to follow a structured process to resolve it with your energy supplier.
Gathering evidence and documentation
Before contacting your supplier, collect all relevant documents. This includes past bills, meter readings (especially photographic evidence), copies of your contract, and any correspondence you have had with the supplier. Detailed records strengthen your case.
Contacting your supplier: initial steps
Contact your energy supplier directly to explain the issue. Many suppliers have dedicated customer service lines or online portals for billing enquiries. Clearly state your concern, provide your evidence, and ask for a detailed explanation of the charges.
Formal complaints procedure: what to expect
If your initial contact does not resolve the issue, you will need to escalate it through your supplier's formal complaints procedure. All energy suppliers are required to have one under The Gas and Electricity (Consumer Complaints Handling Standards) Regulations 2008. They should acknowledge your complaint within two working days and aim to resolve it within 14 days. If unresolved, they must keep you informed for up to eight weeks. Keep a detailed record of all communications, including dates, times, names of representatives, and summaries of discussions.
Your rights under the back-billing rule
The 'back-billing' rule is a crucial protection for consumers. It prevents energy suppliers from charging you for unbilled energy used more than 12 months ago if the error was their fault. This rule applies if they failed to bill you correctly, or did not use a meter reading you provided.
The Ombudsman provides a free, independent dispute resolution service. You can contact them by phone on 0330 440 1624, by email at [email protected], or via their website.
Preparing your case for the Ombudsman
When you contact the Energy Ombudsman, you will need to provide all the details of your complaint, including your supplier's name, your account number, a timeline of events, and all supporting evidence you have gathered. Be clear and concise in your explanation.
What powers does the Ombudsman have?
The Energy Ombudsman can investigate your complaint and make a decision. They can require your energy supplier to apologise, explain what went wrong, correct your bill, or even pay compensation. Their decisions are binding on the energy supplier, who must implement any accepted decision within 28 days.
Implementing the Ombudsman's decision
Once the Ombudsman makes a decision, your energy supplier must comply with it. This means they will have to implement any required actions, such as issuing a refund or adjusting your account.
Taking proactive steps can significantly reduce the likelihood of being overcharged in the future.
Submitting regular meter readings
For non-smart meters, or if your smart meter is offline, submitting regular meter readings yourself is good practice. This provides an extra layer of verification and helps ensure your bills are based on actual consumption, not estimates. If you have an online smart meter, readings are sent automatically, making manual submissions unnecessary.
Monitoring your energy usage with smart tools
Tools like the Fuse Energy app provide clear, real-time energy usage data, empowering you to monitor your consumption and identify potential discrepancies proactively. By tracking your usage, you can quickly spot unusual patterns or high consumption that might indicate an issue. Fuse also offers 24/7 human customer support to help you understand your bills and address any concerns, aiming to resolve issues quickly before they escalate.
Understanding your contract and tariff
Regularly review your energy contract and tariff details. Ensure you understand the unit rates, standing charges, and any terms that might affect your billing. If you are on a fixed-term contract, be aware of when it ends and what happens next.
Regularly reviewing your bills
Make a habit of checking each energy bill thoroughly as soon as it arrives. Do not just pay it; scrutinise the readings, charges, and consumption figures. Early detection of errors makes resolution much easier. For free, independent advice, you can also contact Citizens Advice.
