Direct answer: To complain about broadband mis-selling in the UK, tell the provider clearly what you were promised, why the sale was misleading and what remedy you want. Keep evidence, ask for a written response and, if the complaint remains unresolved after eight weeks or you receive a deadlock letter, take it to an approved alternative dispute resolution scheme.
- Mis-selling can include inaccurate claims about price, speed, contract length, setup fees or availability at your address.
- Make the complaint to the provider first and keep a dated record of every contact.
- Ask for a specific outcome, such as cancellation without an early exit charge, correction of the contract or repayment of wrongly charged sums.
- Do not stop paying an undisputed bill whilst the complaint is open, as this can create a separate payment dispute.
How do I complain about broadband mis-selling in the UK?
Start with a written complaint to the provider, setting out the misleading claim, your evidence and the outcome you want. Broadband mis-selling is not simply being disappointed with a service. It means the information or sales process led you to agree to a contract on a false or incomplete basis.
Common examples include being quoted a monthly price that did not make clear compulsory charges, being told a service was available at an address when installation could not proceed, or being given misleading information about a contract commitment. A sales claim about expected speed can also be relevant where it was presented as suitable for your needs without a proper address check.
Be precise rather than emotional. State the date of the sale, whether it took place online, by telephone or in person, what was said or shown, and why it mattered to your decision. Ask the provider to log the case as a formal complaint and give you a reference number. Ofcom requires communications providers to have and follow a complaints handling procedure (Ofcom, 2024).
What evidence do I need for a broadband mis-selling complaint?
The strongest complaint matches each disputed sales claim with a record that shows what you were actually sold. Save the order confirmation, contract summary, pre contract information, welcome emails, screenshots, bills and any promotional wording you relied on. Write down the date, time and number used for telephone calls, together with the adviser’s name if you have it.
A simple timeline is often more useful than a long account. Begin with the advert or conversation, then the order, installation or activation, the first bill and each attempt to resolve the issue. If the dispute concerns speed or technology, include the service description and address details supplied during the order. FTTP, FTTC, cable, 4G and 5G home broadband can have different installation processes and performance expectations.
Keep copies outside the provider’s account portal in case your access changes after cancellation. You can ask the provider to review its own sales notes or call recording where relevant. Citizens Advice can explain practical consumer complaint options if you need independent help presenting your case (Citizens Advice, 2024).
What should I say in my complaint to the broadband provider?
Use a short, factual statement that identifies the promise, the problem and the remedy you consider fair. Avoid vague wording such as “the deal was not what I expected”. Instead, explain exactly what you understood before ordering and point to the evidence that supports this.
You could write: “I agreed to this broadband contract on [date] because I was told [claim]. My order confirmation and first bill show [difference]. Had I been given accurate information, I would not have agreed to these terms. I am asking for [remedy], and for written confirmation that no early exit charge will apply if the contract is cancelled.”
Your remedy depends on the facts. Cancellation without a fee may be appropriate where the misleading point was fundamental to the purchase. In other cases, a billing correction, removal of an incorrect charge or a revised agreement may resolve the matter. Ask the provider to explain its decision in writing, including the evidence it used. That response will matter if you need to escalate.
| Complaint stage | What to provide | What to ask for |
|---|---|---|
| Initial complaint | Order documents, bills and a clear timeline | A formal investigation and complaint reference |
| Provider review | Any reply that conflicts with the original sales claim | A written explanation and a fair remedy |
| Escalation | Your full complaint record and final provider response | An independent decision through approved dispute resolution |
What if my broadband provider rejects my complaint?
Ask for a final written position, then use alternative dispute resolution if eight weeks have passed or the provider issues a deadlock letter. A deadlock letter means the provider considers that it cannot resolve the complaint with you. Do not treat a first refusal as the end of the process if it has not addressed your evidence or the remedy you requested.
Reply once with the missing points in a structured way. Quote the complaint reference, identify the unanswered evidence and restate the outcome you seek. This gives the provider a fair opportunity to correct an error and creates a clean record for escalation.
Ofcom says customers can take an unresolved complaint to an approved alternative dispute resolution scheme after eight weeks, or earlier with a deadlock letter (Ofcom, 2024). The scheme will consider the documents from both sides, so concise evidence is more persuasive than repeated calls. Continue to keep payment records and correspondence until the case is closed.
Can I cancel or switch after broadband mis-selling?
You may be able to cancel without an early exit charge if the mis-selling was material, but confirm this in writing before placing a replacement order. Do not assume that opening a complaint automatically ends the contract. A provider may continue the service and billing whilst it investigates, unless it agrees otherwise.
If you need to change provider, ask first whether the complaint outcome includes cancellation, any charge waiver and a service end date. That prevents a rushed switch creating overlapping bills or an avoidable loss of connection. Installation timing also matters, particularly where a new FTTP service requires an appointment or building work.
For many residential fixed broadband switches, One Touch Switch means the new provider manages the switching process and the customer contacts only the new provider. One Touch Switch went live on 12 September 2024 and is run by TOTSCo (TOTSCo, 2024). A mis-selling dispute can still require separate agreement about fees, final billing and the appropriate cancellation date.
How can I avoid broadband mis-selling when choosing a new deal?
Compare the full contract terms for your exact address before ordering, rather than deciding from a headline monthly figure. Check the total cost across the commitment period, including setup charges, delivery charges where applicable and any price changes stated in the contract. Prices, availability and installation options are postcode specific and can change during the month.
Pay particular attention to contract length, the technology offered and whether installation is self setup or engineer led. A lower monthly figure can be less suitable if it locks you into a longer commitment, includes charges you had not budgeted for or does not meet the needs of a busy household, home office or small business.
For new contracts sold from 17 January 2025, inflation linked mid contract price rises are banned. Any planned mid contract rise must be stated in pounds and pence at the point of sale (Ofcom, 2024). Save the contract summary before you complete an order. It is the clearest record of the deal you accepted.
Frequently asked questions
Is slow broadband always mis-selling?
No. Slow performance alone does not prove mis-selling. The question is whether the provider gave misleading information about the service, speed expectation or suitability before you agreed to the contract. Compare the sales material, contract summary and address specific information with what was installed and delivered.
Can I complain if an installation date keeps changing?
Yes, especially if the installation timing was a decisive sales promise and you can show what was stated before you ordered. Ask the provider to explain the cause of the delay, confirm the revised date in writing and set out the remedy it will offer if the original information was misleading.
Should I cancel my direct debit during a complaint?
Usually, no. Cancelling a direct debit can leave undisputed charges unpaid and complicate the complaint. Pay amounts you accept are due where possible, challenge disputed charges clearly and keep your payment evidence. Ask the provider how it will treat the disputed balance whilst it investigates.
Does One Touch Switch settle a mis-selling complaint?
No. One Touch Switch manages the practical switching process for eligible residential fixed broadband moves, but it does not decide whether a provider mis-sold a contract or whether an early exit charge should be removed. Keep the complaint open until you have a written outcome on fees and final billing.
