Important Safety Warning: Beware of fake customer service numbers on search engines. Only use official channels. Scammers frequently buy ads to promote fraudulent phone numbers. Sky UK staff will never ask for your account PIN, your online portal password, or ask you to download remote desktop software to “fix your router” over the phone.

-
Availability: Telephone support and live chat are available Monday to Sunday from 8:30 AM to 7:30 PM (UK Time).
-
Timeline: Sky aims to resolve complaints within 7 working days. (Note: Under Ofcom rules, if a Sky engineer misses an appointment, or a broadband repair/installation is delayed beyond 2 working days, they must issue automatic compensation credits to your bill).
Level 2: Formal Corporate Escalation (Notice of Dispute)
-
Who to contact: If standard customer service cannot resolve the issue, you must formally escalate it to their central correspondence team. Send a written letter detailing your account number, a timeline of the issue, and your desired resolution. You must explicitly request a “Deadlock Letter” if they refuse your proposed resolution. Sending this via Royal Mail Signed For is highly recommended.
-
Complaints Address: Customer Complaints, Sky Subscriber Services Ltd, PO Box 43, Livingston, West Lothian, EH54 7DD
-
Timeline: Under Ofcom regulations, Sky has a maximum of 8 weeks to issue a final resolution or a Deadlock Letter.
Level 3: Regulatory Authority (Government Ombudsman)
-
Authority: CISAS (Communication and Internet Services Adjudication Scheme). (Note: Sky does not use the Communications Ombudsman).
-
Portal/Contact: CISAS is the Ofcom-approved, free dispute resolution service operated by CEDR for Sky complaints. You can submit a complaint online or by email:
-
Website: cedr.com/consumer/cisas/
-
Email: cisas@cedr.com
-
Phone: 020 7520 3814
-
Timeline (CRITICAL): You can only refer your complaint to CISAS after you receive a Deadlock Letter from Sky, OR if 8 weeks have passed since your initial complaint without a resolution. You must escalate the complaint to CISAS within 12 months of receiving your Deadlock Letter.
Level 4: Legal Action (Final Step)
-
Pre-Litigation: Before commencing legal proceedings, UK legal protocols require you to send a formal “Letter Before Action” (LBA) to Sky’s corporate legal headquarters. This letter must outline your claim, the exact legal or contractual breach, the evidence, and the financial remedy you seek, giving them a final 14 to 30 days to settle.
-
Legal Address: Sky UK Limited, Legal Department, Grant Way, Isleworth, Middlesex, TW7 5QD
-
Court: If the LBA fails and CISAS cannot resolve it, you can file a lawsuit. For financial claims up to £10,000 in England and Wales, you can use the Money Claim Online (MCOL) portal to enter the Small Claims Track. For complex claims, you will likely need to instruct a solicitor and proceed to the County Court.
