Zen Internet ombudsman & regulator routes
Which ombudsman handles Zen Internet complaints?
Communications Ombudsman (Ombudsman Services). Once Zen Internet’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 Zen Internet?
Not for individual disputes: Ofcom sets the rules for the sector but does not resolve personal complaints or award compensation. Complain to Zen Internet 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 Zen Internet to Ofcom to flag systemic problems, but that will not get your own money back.
Laws that protect you
