BT ombudsman & regulator routes
Which ombudsman handles BT complaints?
Communications Ombudsman (Ombudsman Services). Once BT’s own complaints process is exhausted (after 6 weeks or a deadlock letter), you can take your complaint there for free. Go to the ombudsman. Read our Communications Ombudsman (Ombudsman Services) guide.
Can you complain to Ofcom about BT?
Not for individual disputes: Ofcom sets the rules for the sector but does not resolve personal complaints or award compensation. Complain to BT directly first and keep written records, then escalate to Communications Ombudsman (Ombudsman Services) if it stays unresolved after 6 weeks or you receive a deadlock or final-response letter. You can still report BT to Ofcom to flag systemic problems, but that will not get your own money back.
Laws that protect you
Consumer Rights Act 2015
Your broadband and phone service must be provided with reasonable care and skill. If speeds or reliability fall well short of what BT sold you, you’re entitled to a remedy.
Ofcom Automatic Compensation Scheme
BT is a signed-up provider, so it must pay set daily amounts automatically for total loss of service, missed engineer appointments, and delays starting a new service - you should not have to ask.
Ofcom General Conditions
Since January 2025 any mid-contract price rise must be set out in pounds and pence when you sign up. If BT didn’t make an increase clear, you may be able to leave penalty-free.
Communications Act 2003
The framework behind the Digital Voice (copper switch-off) migration, including protections for landline-dependent and vulnerable customers.
Tips for BT complaints
- Log every outage with dates, times and fault reference numbers - it’s the evidence for an automatic compensation claim
- Total loss of service, missed engineer visits and delayed starts are covered by Ofcom’s automatic compensation scheme, so chase BT if it isn’t paid
- If a mid-contract price rise wasn’t shown in pounds and pence when you signed up, ask to leave penalty-free
- Run a speed test and compare it against the minimum guaranteed speed on your contract before you complain about broadband
- If you’re being moved to Digital Voice and rely on your landline, ask BT about battery back-up and priority-fault support
- BT has 6 weeks to resolve a complaint - after that, or with a deadlock letter, escalate free to the Communications Ombudsman
