Understanding Energy Mis-Selling

Understanding Energy Mis-Selling

Energy mis-selling happens when a gas or electricity supplier, or one of their agents, uses misleading or high-pressure tactics to persuade you to sign up for a contract. This can include providing false information, not explaining important details, or encouraging you to switch to a tariff that isn’t right for your needs.

Common Examples of Energy Mis-Selling

Mis-selling can take many forms. Some of the most frequent examples include:

  • Incorrect contract terms: You’re told the contract is for a fixed period, but it turns out to be variable, or the price is higher than promised.

  • False promises: The salesperson claims you’ll save money or receive special discounts that don’t exist.

  • Unsuitable tariffs: You’re encouraged to sign up for a tariff that doesn’t match your usage, leading to higher bills.

  • Not providing key information: Important details about exit fees, cooling-off periods, or contract length are left out or misrepresented.

  • Switching without consent: Your supplier is changed without your clear permission (sometimes known as “slamming”).

How Mis-Selling Can Affect You

Being a victim of energy mis-selling can have real consequences. You might end up paying more than you expected, facing unexpected fees, or struggling to switch back to your previous supplier. In some cases, you could find your energy service disrupted or lose access to deals that would have suited you better.

Your Rights as a Consumer

In the UK, you are protected by strong consumer rights and energy regulations. Suppliers must follow rules set by Ofgem, the energy regulator. These rules require suppliers to treat customers fairly, provide clear and accurate information, and ensure that any contract you sign is suitable for your needs.

If you believe you’ve been mis-sold an energy contract, you have the right to:

  • Complain to your supplier: They must investigate your complaint and respond within a reasonable time.

  • Cancel the contract: In many cases, you have a 14-day cooling-off period to cancel without penalty.

  • Escalate your complaint: If your supplier doesn’t resolve your issue, you can take your complaint further. The Ofgem guidelines, as enforced by the Energy Ombudsman, are there to protect you and help resolve disputes between consumers and energy suppliers.

This can help you draft the right letter and understand the next steps if you feel you’ve been mis-sold an energy product.

When and Why to Complain About Energy Mis-Selling

When and Why to Complain About Energy Mis-Selling

Energy mis-selling happens when an energy supplier or their representative gives you false, misleading, or incomplete information to persuade you to switch providers or sign up for a new tariff. This can include exaggerating savings, hiding important terms, or pressuring you into making a quick decision. Under UK consumer law, including the Consumer Protection from Unfair Trading Regulations 2008, you have the right to expect honest and transparent information when choosing your energy supplier.

Situations That Warrant a Complaint

You should consider making a complaint if you have experienced any of the following:

  • Misleading Claims: The salesperson promised savings or benefits that turned out to be untrue, or they failed to explain important costs or contract terms.

  • Pressure Selling: You felt rushed, harassed, or pressured into signing up for a deal without enough time to consider your options.

  • Lack of Clear Information: Essential details about tariffs, exit fees, or contract length were not provided or were hidden in small print.

  • Switching Without Consent: Your energy account was switched to a new supplier without your clear agreement (sometimes called “slamming”).

  • Incorrect Billing or Back Billing: You received bills that do not match what was agreed, or you have been charged for energy you did not use.

If your issue relates more specifically to billing errors, such as being charged for energy you did not use, you may also want to review how to complain to a supplier about back billing.

How to Identify If You Have Been Mis-Sold Energy Services

It can sometimes be difficult to spot mis-selling, but common signs include:

  • Promises of savings that are not reflected on your bill.

  • Receiving a contract or welcome letter with details that do not match what you were told.

  • Feeling you were not given enough time or information to make an informed decision.

  • Discovering hidden fees or charges after signing up.

  • Being switched to a new energy supplier without your knowledge.

If you recognise any of these situations, you may have been mis-sold an energy product or service.

Why It’s Important to Complain Promptly

Making a complaint as soon as you notice a problem is crucial. Acting quickly helps you:

  • Protect your legal rights: Some remedies, such as cancelling a contract, may only be available within a certain timeframe.

  • Prevent further losses: Prompt action can stop additional charges or incorrect billing.

  • Provide clear evidence: The sooner you complain, the easier it is to remember details and gather supporting documents.

If you need help structuring your complaint, you can use a letter to complain to your energy supplier, which can be adapted for mis-selling cases.

What Outcomes Can You Request?

When you complain about energy mis-selling, you can ask your supplier for a range of remedies, including:

  • A full or partial refund for any money you have lost as a result of the mis-selling.

  • Contract cancellation without penalty, allowing you to switch to a different supplier or tariff.

  • Compensation for inconvenience or distress caused by the mis-selling.

  • Correction of your account to ensure you are on the agreed tariff and billed correctly.

Suppliers are required to investigate your complaint fairly and respond within a reasonable timeframe. If your issue is not resolved, you may have the right to escalate your complaint to the Energy Ombudsman or seek further advice.

Understanding when and why to complain gives you the best chance of protecting your interests and securing a fair outcome.

How to Write a Letter to Complain About Energy Mis-Selling

Writing a clear and effective letter is an important first step if you believe you’ve been a victim of energy mis-selling. Here’s a step-by-step guide to help you draft your complaint, along with practical tips to make sure your concerns are taken seriously.

1. Gather Your Information

Before you start writing, collect all the relevant details about your account and the mis-selling incident. This includes:

  • Your full name and address

  • Your account number (found on your bill or contract)

  • The name of the energy supplier and, if possible, the salesperson involved

  • Dates and times of any relevant conversations or visits

  • Copies of contracts, emails, or other evidence

Having these details ready will make your complaint clearer and easier for the company to investigate.

2. Structure Your Letter

A well-structured letter is more likely to get a prompt and helpful response. Consider using this format:

a. Your Details:
Start with your name, address, and contact information. Include your energy account number for easy reference.

b. Description of the Issue:
Explain clearly what happened. For example, “On 10 March 2024, I was contacted by your sales representative who told me I would save money by switching tariffs. However, after switching, I discovered the tariff is actually more expensive than my previous plan.”

c. Evidence of Mis-Selling:
List any evidence you have, such as written promises, misleading statements, or comparison figures. Attach copies if you’re sending the letter by post or email.

d. The Resolution You Want:
State what you would like the company to do. This could be switching you back to your previous tariff, cancelling a contract, or providing compensation.

e. Request for Response:
Ask for a response within a reasonable timeframe, such as 14 days.

3. Keep Your Letter Clear, Polite, and Factual

  • Be concise: Stick to the facts and avoid emotional language.

  • Be polite: A courteous tone helps maintain a constructive dialogue.

  • Be specific: Refer to dates, names, and documents where possible.

Here’s a simple example to get you started:

“I am writing to complain about the way your services were sold to me. On [date], I was advised that switching to your tariff would save me £X per month. However, I have since discovered this is not the case. Please find attached copies of my previous and current bills.”

If you’d like a ready-made template, you can find a selection of energy complaint letter templates to help you get started.

4. Sending Your Letter and Keeping Records

  • Send your complaint to the supplier’s official complaints address (check their website or your contract).

  • Send by recorded delivery if posting, or request a read receipt if emailing.

  • Keep copies of your letter and any replies you receive.

  • Record dates of all communications for your records.

Keeping a clear record of your complaint is important if you need to escalate the issue to the Energy Ombudsman or another body later on.

What to Expect After Sending Your Complaint

What to Expect After Sending Your Complaint

Once you have sent your complaint letter about energy mis-selling, it’s important to know what typically happens next and what your rights are throughout the process. Here’s what you can expect:

How Energy Suppliers Usually Respond

Most energy suppliers are required to acknowledge your complaint promptly, often within a few working days. They should then provide a full response – sometimes called a ‘final response’ – within eight weeks. This is the maximum time allowed under industry guidelines for most energy complaints. During this period, your supplier may contact you for more information or clarification about your concerns.

Investigation and Possible Outcomes

After receiving your complaint, your supplier will investigate the issues you’ve raised. This may involve reviewing your account, checking sales records, and speaking to the sales agent involved. They should keep you updated throughout the process.

Possible outcomes of your complaint can include:

  • An apology and explanation of what went wrong

  • Correction of any errors on your account

  • Cancellation of a contract agreed to under misleading circumstances

  • Refunds or compensation for any financial loss or inconvenience

Your rights are protected under UK consumer law, including the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013, which set out the information you should receive before entering a contract and your right to cancel if you’ve been misled.

If You’re Not Satisfied With the Response

If your supplier does not resolve your complaint to your satisfaction, or if they fail to respond within eight weeks, you have the right to escalate the issue. In such cases, you can complain to the Energy Ombudsman. The Energy Ombudsman is an independent body that can review your case and make a decision, which may include ordering the supplier to take action or provide compensation.

The Role of the Energy Ombudsman

The Energy Ombudsman will look at all the evidence from both you and your supplier. Their service is free for consumers, and their decision is binding on the supplier if you accept it. This provides an extra layer of protection if you feel your complaint hasn’t been handled fairly.

Next Steps

Keep records of all communication with your supplier, including dates and copies of letters or emails. If you need to escalate your complaint, these records will help support your case. Remember, you have strong legal rights under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 if you have experienced energy mis-selling.
