TL;DR
- Mis-selling includes inaccurate coverage claims, wrong tariffs, undisclosed charges, and unsuitable upgrades pushed without explaining the cost implications.
- Keep every piece of evidence from the point of sale: screenshots, emails, order confirmations, and call recordings if the operator supplies them.
- Raise a formal written complaint with the operator first; they have eight weeks to resolve it.
- After eight weeks, or when you receive a deadlock letter, escalate to an Ofcom-approved ADR scheme: CISAS or Ombudsman Services: Communications.
- Proven mis-selling can result in contract rescission, refunds, or compensation without an early termination fee.
What counts as mobile contract mis-selling
Mis-selling in mobile contracts covers any situation where the information provided to a customer at the point of sale is false, misleading, or materially incomplete in a way that influences the customer's decision. Ofcom's General Conditions of Entitlement require that providers give consumers accurate, clear, and comprehensive pre-contract information. Breaching these obligations can constitute mis-selling under both Ofcom's regulatory framework and the Consumer Protection from Unfair Trading Regulations 2008.
The most frequent forms include: quoting a monthly price that excludes VAT or mandatory add-ons; claiming full coverage at a customer's address when the network's own data shows limited or no indoor signal; representing a tariff as unlimited when it is in fact subject to fair use caps; pressuring an existing customer into an upgrade on terms presented as better than they are; and failing to disclose that a quoted price is an introductory rate that will rise mid-contract. Each of these creates a potential basis for a formal complaint.
Gathering evidence before complaining
A mis-selling complaint stands or falls on documentation. The core evidence to assemble is whatever was said or shown to you at the point of sale and what the contract actually delivers. This means retaining the original order confirmation email, any written quotes, the contract terms and conditions as they existed when you signed, and any screenshots of coverage checks or tariff comparisons the operator directed you to. If the sale was made by phone, request a copy of the call recording - UK operators are required under data protection law to provide this on a subject access request to the ICO's standard under the UK GDPR.
Supporting evidence should include a record of the problems you have experienced since signing: dates and times of call failures or lack of coverage, screenshots of your actual monthly bills if they differ from what was quoted, and any written communications with the operator's customer service team. The stronger the contrast between what was represented and what has been delivered, the stronger the complaint. A chronological log maintained from the point you first noticed the discrepancy is particularly useful when escalating to an ADR scheme.
Making the formal complaint to the operator
Before escalating to a regulator or ADR scheme, you must raise the complaint directly with the operator. Do this in writing - email rather than phone wherever possible, as this creates an automatic evidential record. Address the complaint to the operator's complaints team specifically, not general customer services, and state clearly that you are making a formal complaint. Reference the specific misrepresentation or conduct, when it occurred, and what remedy you are seeking - whether that is a refund of overcharged amounts, contract rescission, or compensation.
Ofcom's General Conditions require providers to acknowledge complaints promptly and to resolve them or issue a deadlock letter within eight weeks. Keep a record of all complaint reference numbers and every response received. If the operator resolves the complaint to your satisfaction at this stage, retain all correspondence in case issues recur. If the operator fails to respond adequately within eight weeks, or issues a deadlock letter indicating it considers the matter closed, you are then entitled to proceed to ADR.
| Stage | Action | Timeframe | Outcome trigger for next stage |
|---|---|---|---|
| 1 — Internal complaint | Submit formal written complaint to operator | Day 0 | No resolution after 8 weeks, or deadlock letter |
| 2 — ADR referral | Refer to CISAS or Ombudsman Services: Communications | After 8 weeks or deadlock | ADR issues binding determination |
| 3 — Ofcom complaint | Report systemic mis-selling to Ofcom | Any time | Regulatory investigation (does not award individual compensation) |
| 4 — Small claims | County court claim for financial loss | After ADR if financial loss remains unresolved | Court judgment |
The ADR and CISAS route
Ofcom requires all mobile operators to be members of an approved Alternative Dispute Resolution scheme. The two approved schemes are CISAS (Communications and Internet Services Adjudication Scheme) and Ombudsman Services: Communications. Your operator's terms and conditions will specify which scheme they are affiliated with. Both schemes are free to consumers and independent of the operators. You submit your complaint, supporting evidence, and the operator's final response or deadlock letter, and an adjudicator reaches a determination.
ADR determinations can require the operator to pay compensation, issue refunds, amend the contract, or release the customer from the contract entirely. Operators are bound by the determination if the customer accepts it; the customer retains the right to proceed to court if they do not accept the outcome. Ofcom publishes annual data on ADR performance, which shows complaint volumes and resolution rates by scheme. The ADR process does not prevent you from also reporting the mis-selling to Ofcom directly, though Ofcom handles regulatory enforcement rather than individual compensation.
Remedies available in mis-selling cases
The range of remedies depends on the nature and severity of the mis-selling. Where a customer was placed on the wrong tariff, the typical remedy is a retrospective rebate of any overcharging and correction of the tariff going forward. Where coverage was materially misrepresented, the operator may agree to release the customer from the contract without an ETF - which can represent a significant financial saving on a 24-month contract. In cases of deliberate or systematic mis-selling, Ofcom has powers to impose fines on operators, though this does not directly compensate individual customers.
Compensation for distress or inconvenience is less consistently awarded but is available through the ADR process. Consumers Protection from Unfair Trading Regulations 2008 also provide rights to unwind a transaction where a misleading action directly caused the purchase decision - this gives consumers a statutory right to unwind within 90 days in the most serious cases. If a customer has incurred out-of-pocket costs as a direct result of the mis-selling (for example, purchasing a Wi-Fi calling device because in-building coverage was inadequate despite operator assurances), those costs can form part of the compensation claim.
What this means in practice
Marcus signs a 24-month contract in a high-street shop in Bristol, having been told by the salesperson that his flat - in a Victorian terrace - will receive strong indoor 4G coverage. He takes no screenshots at the time. On receiving his first bill he finds it is £4 per month higher than quoted because a line management fee was not mentioned at point of sale, and his indoor signal is consistently two bars or fewer. He immediately screenshots his bills, makes contemporaneous notes of call failures, and submits a subject access request for the store CCTV and any call-centre records. He raises a formal complaint in writing citing both the billing discrepancy and the coverage misrepresentation. The operator disputes the coverage claim but agrees to a £4/month credit for the undisclosed charge. Marcus escalates to CISAS after eight weeks, submitting his bills, notes, and the operator's response. The adjudicator finds a billing misrepresentation was made and awards a refund of overcharged amounts plus a one-off compensation payment of £50, with the monthly rate corrected going forward.

Frequently Asked Questions
What is mobile contract mis-selling?
Mobile contract mis-selling occurs when a provider gives you false, misleading, or materially incomplete information at the point of sale that influences your decision to sign or renew. This can include quoting a monthly price that excludes mandatory fees, overstating network coverage, misrepresenting data allowance limits, or failing to disclose mid-contract price rises. It falls under Ofcom's General Conditions and the Consumer Protection from Unfair Trading Regulations 2008.
What are common examples of mobile mis-selling?
Common examples include being told a tariff is “unlimited” when it has a fair use threshold, having coverage at your home address described as reliable when the operator's own tool shows limited indoor signal, being placed on a tariff with a higher monthly cost than discussed, receiving a bill that includes charges not disclosed at sign-up, or being pushed into an upgrade before the end of your contract without a clear explanation of the new total cost.
How do I complain about mobile contract mis-selling?
Submit a formal written complaint to the operator's complaints team, clearly identifying the misrepresentation, when it occurred, and what remedy you seek. Email is preferable as it creates an automatic record. The operator has eight weeks to resolve the matter or issue a deadlock letter. If neither occurs, or the response is unsatisfactory, refer the complaint to the operator's ADR scheme - either CISAS or Ombudsman Services: Communications - both of which are free to consumers.
What evidence do I need for a mobile mis-selling complaint?
Gather the original order confirmation, any written quotes or tariff comparisons, the contract terms as they stood at sign-up, screenshots of coverage checks you were directed to, and copies of bills showing discrepancies. For phone sales, submit a subject access request for the call recording. Maintain a chronological log of problems experienced, including dates, times, and nature of the failure. The sharper the contrast between what was stated and what occurred, the stronger the case.
Can I exit my mobile contract if I was mis-sold?
Yes, in established mis-selling cases. If an ADR adjudicator finds the mis-selling claim proven, they can require the operator to release you from the contract without an early termination fee. In serious cases, the Consumer Protection from Unfair Trading Regulations 2008 also provide a statutory right to unwind a contract within 90 days of the misleading action. During the 14-day cooling-off period on distance-sold contracts, no reason is needed to cancel.
