Telecom complaint route

Complain to the provider first

Give account details, fault references, dates, charges and the outcome requested.

Ask for deadlock if stuck

If the provider will not resolve the issue, ask for its final position or deadlock letter.

Escalate if unresolved

If unresolved after the relevant waiting period or deadlock, use the provider’s ADR route if the complaint is in scope.

  • Explain the financial or service impact (unexpected charges, loss of service, contract issues).
  • Request a specific remedy (bill correction, refund, contract amendment, compensation, or service fix).
  • Ask for a written response within a reasonable timeframe.

Common issues people complain about (Mobile & broadband)

Typical themes include: Billing dispute, Overcharge, Contract cancellation, Poor signal / service, Early termination fee, Refund request. Keep your complaint focused on the main issue and avoid unrelated grievances.

What to include

  • Dates of disputed charges or service failures.
  • Details of any agreed tariffs or promotions.
  • Records of previous complaints and responses received.
  • Any reference numbers provided during contact.

Your rights as a telecoms customer

Telecoms providers must bill you accurately and provide services with reasonable care and skill under UK consumer law. Ofcom rules also require providers to handle complaints fairly and transparently.

  • If you believe you were mis-sold a contract, set out clearly what was represented and what differs from the agreement.
  • If you are charged early termination fees, request justification and a clear breakdown.
  • If service quality is persistently poor, explain how it has affected your use and request a remedy.

Referring calmly to consumer rights and Ofcom complaint handling requirements can strengthen your position.

Escalation and timeframes

Expected wait: Providers normally have up to 8 weeks to resolve a complaint before ADR becomes available, unless you receive a deadlock letter sooner.

Escalation route: If unresolved after 8 weeks or upon receipt of a deadlock letter, you may escalate to an approved Alternative Dispute Resolution (ADR) scheme such as CISAS for independent review.

Practical tips

  • Keep your complaint factual and concise.
  • Quote exact bill amounts and dates.
  • Request written confirmation of any agreed changes.
  • Retain copies of all correspondence.
