Sky uses CISAS (run by CEDR), not the Communications Ombudsman. Sky broadband, phone, TV and mobile complaints all route to CISAS. Keep a written record of your complaint reference.

Complain to Sky first and ask for a written final response. If they reject you or the deadline passes, you can take it to the CISAS (Communications and Internet Services Adjudication Scheme) for free, and their decision is binding on the company.

Chasing money back, not just lodging a complaint? Cancel or reclaim a Sky broadband mid-contract price rise.
