Complaints

The four-step TalkTalk complaints procedure

From the first call to a binding CISAS ruling. Following the order matters: skipping a step weakens your case.

1

Raise it with TalkTalk

Call 0345 172 0088, use live chat, or fill the complaints web form. Note the date, agent name and reference number. TalkTalk should acknowledge within 5 working days.
2

Wait up to 8 weeks

Under Ofcom rules TalkTalk has up to 8 weeks to resolve a complaint. Most are resolved before then. If you accept the outcome, the case is closed. If you do not, ask for a deadlock letter, which lets you escalate without waiting the full 8 weeks.
3

Escalate to CISAS

If TalkTalk does not resolve the complaint in 8 weeks or issues a deadlock letter, you can take the case to the CISAS alternative-dispute-resolution scheme. CISAS is free for consumers and rulings are binding on TalkTalk.
4

Inform Ofcom

Ofcom does not handle individual complaints but tracks them by provider. Reporting your issue at ofcom.org.uk feeds the Q1, Q2, Q3 and Q4 broadband complaints league tables, which already place TalkTalk in the worst bracket for 2025.

FAQ

Contacting TalkTalk, your questions answered

What is the best way to contact TalkTalk?

For account questions, bills and basic faults, the fastest option is live chat in My Account: the chat-bot can usually resolve billing or password issues in two minutes. For anything that needs a human (cancellation, complaint, complex fault), the phone (0345 172 0088) is still the most reliable channel. Social media (X, Facebook) is useful for nudging slow cases but rarely closes them outright.

Is 0345 172 0088 free to call?

0345 numbers are charged at your normal landline or mobile rate and are included in most inclusive minute bundles, so for most customers the call is effectively free. If you are out of allowance, it costs the same as a call to a 01 or 02 number. The 0800 sales line (0808 178 8896) is free from UK landlines and mobiles.

When is TalkTalk customer service open?

The main customer service line (0345 172 0088) is open Monday to Friday 08:00 to 20:00 and Saturday 09:00 to 18:00. Live chat in My Account is available 24 hours via the bot, with humans available in the same hours as the phone line. Faults can be reported in My Account or by chat at any time.

How do I report a TalkTalk fault?

Log into My Account and use the “Report a problem” tool. It runs an automated line test and either fixes the issue remotely (most common) or books an Openreach engineer slot. If the line is fully down and you cannot reach My Account, call 0345 172 0088.

How do I escalate a TalkTalk complaint?

Follow the four steps above. If you have hit the 8-week limit or received a deadlock letter, file the case with CISAS. CISAS will request TalkTalk’s file, give both sides a chance to comment, and issue a binding ruling within around 6 weeks. The service is free for consumers and you can claim up to £10,000 in remedies.
