What customers complain about

Customers most often complain to Vodafone about broadband faults, service and provisioning: Ofcom's Q4 2025 data attributed 52% of Vodafone's broadband complaints to those issues, and rated Vodafone the most-complained-about broadband provider at 11 complaints per 100,000 customers versus an industry average of 7. Vodafone's mobile complaints, by contrast, ran below average (2 per 100,000 versus 3). Reported themes on review platforms also include billing disputes and mid-contract price increases, but these are reported, not verified. To complain, contact Vodafone by phone, online form or post; it aims to acknowledge within about three days and resolve within six weeks (eight for financial products). If it cannot resolve the dispute, or after eight weeks or a deadlock letter, you can take the case free of charge to CISAS.

Complaint categories

1
Broadband faults, service and provisioning52%
Problems with the broadband service, faults and provisioning were the dominant driver of Vodafone broadband complaints to Ofcom.
Ofcom Q4 2025 data reported that 52% of Vodafone's broadband complaints were driven by faults, service and provisioning issues, with Vodafone the most-complained-about broadband provider.
2
Billing, payments and mid-contract price increases
Billing disputes and reaction to mid-contract price increases are a recurring source of telecoms complaints.
Ofcom noted the Q4 2025 rise in pay-monthly mobile complaints across the sector was mainly driven by mid-contract price increases; provider-specific billing themes on review platforms are reported, not verified.

Complaints handling
How complaints are recorded, escalated and closed has historically been a weak point for Vodafone.
Historic: in 2016 Ofcom fined Vodafone for, among other things, failing to handle complaints fairly and failing to tell customers in writing of their right to third-party dispute resolution after eight weeks.

Complaint journey

1
Complain to Vodafone
Raise your complaint by phone, online form or post.
Typical responseUp to 3 days
What happens
Contact Vodafone on 191 (free from a Vodafone mobile) or 0333 304 0191, via the online complaint form at complaints.vodafone.co.uk, or by post to the Specialist Care Manager at Vodafone Limited, The Connection, Newbury, RG14 2FN. Vodafone asks for up to about three days to review your details and get in touch. Keep the complaint reference it gives you.
2
Escalate within Vodafone
Ask for your complaint to be escalated if you are not satisfied.
Typical responseVaries
What happens
If the first response does not resolve things, ask Vodafone to escalate the complaint. Vodafone's Customer Complaints Code sets out how unresolved complaints are reviewed and progressed toward a final response.
3
Get a final response or deadlock letter
Vodafone issues a final response or a deadlock letter.
Typical responseUp to 6-8 weeks
What happens
Vodafone aims to resolve non-financial complaints within six weeks and financial-product complaints within eight weeks. If it cannot, or you remain unhappy, it should provide a final response or a 'deadlock' letter that confirms you can take the matter to independent dispute resolution.
4
Refer to CISAS (or the Financial Ombudsman)
Take an unresolved dispute to the free independent adjudicator.
Typical responseAfter 8 weeks or deadlock
What happens
If your complaint is unresolved eight weeks after you first raised it, or you have a deadlock letter, you can refer it free of charge to CISAS, Vodafone's Ofcom-approved ADR scheme run by CEDR; a CISAS decision is binding on Vodafone. Complaints about a Vodafone financial product go instead to the Financial Ombudsman Service.

Response times

Vodafone asks for up to about three days to acknowledge and look into a new complaint. Its Customer Complaints Code states it aims to resolve non-financial complaints within six weeks and complaints about financial products within eight weeks. Regardless of Vodafone's own six-week aim, your right to escalate to CISAS arises after eight weeks without resolution, or as soon as Vodafone issues a deadlock letter. Complaints about a financial product follow the eight-week route to the Financial Ombudsman Service.

If your complaint isn’t resolved

If Vodafone UK can’t put things right, you can escalate — free of charge — to an independent body:

Know your rights

Consumer Rights Act 2015
Telecoms are a service, so Vodafone must provide them with reasonable care and skill; where a service is faulty you may be entitled to a repeat performance or a price reduction. This is general information, not legal advice.
Ofcom General Conditions of Entitlement
Ofcom's rules require Vodafone to handle complaints fairly and to offer approved alternative dispute resolution (CISAS) after eight weeks or at deadlock. Ofcom enforces these rules but does not settle individual disputes.
Ofcom automatic compensation scheme
For qualifying home broadband and landline problems - delayed repairs, missed engineer appointments and delayed installations - participating providers including Vodafone pay set compensation without you having to ask.

Frequently asked questions

Does Vodafone use the Communications Ombudsman?

No. Vodafone's alternative dispute resolution scheme is CISAS (run by CEDR), not the Communications Ombudsman. Complaints about a Vodafone financial product go instead to the Financial Ombudsman Service.

How do I make a complaint to Vodafone?

Call 191 free from a Vodafone mobile or 0333 304 0191 from any other phone, use the online form at complaints.vodafone.co.uk, or write to the Specialist Care Manager, Vodafone Limited, The Connection, Newbury, RG14 2FN. Vodafone asks for up to about three days to respond.

How long does Vodafone have to resolve my complaint?

Vodafone aims to resolve non-financial complaints within six weeks and financial-product complaints within eight weeks; either way you can go to CISAS after eight weeks or on receiving a deadlock letter.

Is Vodafone really the most-complained-about broadband provider?

In Ofcom's most recent data (Q4 2025) yes - Vodafone had 11 broadband complaints per 100,000 customers against a 7 average. Its pay-monthly mobile complaints, however, were below average at 2 per 100,000.

Who regulates Vodafone?

Ofcom regulates Vodafone's telecoms services. Ofcom can investigate and fine Vodafone for rule breaches - it did so in 2016 - but it does not resolve individual customer disputes; CISAS handles those.
