After 6 weeks, or sooner with a deadlock letter
2. Go to the free ombudsman
If your provider has not resolved a complaint you first raised on or after 8 April 2026 within 6 weeks, you can take it to an independent ombudsman at no cost. Complaints first raised before that date keep the previous 8 week rule. You can go sooner at any point if your provider gives you a deadlock letter, its written confirmation that it cannot resolve the complaint, and you then have 12 months from that letter to refer your dispute.
- There are two Ofcom approved schemes: the Communications Ombudsman and CISAS. Every provider belongs to one and must tell you which.
- Both are free for consumers and eligible small businesses: the provider pays the scheme’s fees, not you.
- The ombudsman can order an apology, a correction to your account, and compensation.
Our step by step guide, Broadband complaints: how to complain and escalate to the ombudsman, walks through this with template wording.
