Avis says complaints about its service can be made by phone or through its online customer service portal. - If it is not resolved
- We could not confirm a general ombudsman or ADR scheme for Avis (UK) from its own pages. If it cannot settle your complaint, ask it in writing which approved ADR provider it uses and whether it will take part, and contact the Citizens Advice consumer service.
- Checked
- 4 October 2026 (company pages and scheme websites). Rules and pages change, so check the official page before you rely on this.
Good to know: The page gives no response time or ADR scheme.
What to Do, Step by Step
- Gather your evidence. Order or account number, dates, receipts, screenshots, emails and what was said on calls.
- Complain in writing using the route above, and ask for a complaint reference. Say what went wrong, what you want, and by when (14 days is reasonable). Our free letter templates can write it for you.
- Keep a record. Note dates, names and reference numbers of every contact. Use email or a form where you can, so you have proof.
- Ask for a final response if you are not getting anywhere, then follow the escalation route above.
- Use other routes if they apply. If the company does not fix it, take it to the free ombudsman or ADR scheme named above. Your bank or card provider may help if you paid by card (Section 75 or chargeback). The Citizens Advice consumer service gives free advice and can pass a report to Trading Standards.
