How to Complain to the Financial Ombudsman Service

Free dispute resolution for banking and financial complaints

Quick Answer

The Financial Ombudsman Service (FOS) is a free, independent service that resolves disputes with banks, insurers, and financial firms. First, complain directly to the firm—give them 8 weeks to respond. If unsatisfied, you can escalate to the FOS. They have power to award compensation up to £385,000. File through their website at: financial-ombudsman.org.uk.

How to File a Complaint

Before contacting the FOS, you must give the firm 8 weeks to respond to your complaint. After 8 weeks, if unresolved, you can contact the FOS. File online at financial-ombudsman.org.uk or by post. Include: your contact details, the firm's details, a clear explanation of the problem, copies of relevant correspondence, and how much compensation you're claiming. The FOS will investigate and contact both you and the firm. They'll hold a hearing (if needed) and issue a binding decision.

The FOS is completely free. You do not pay fees or legal costs.

FAQ

Can I skip the firm's 8-week response period? +

No. You must give the firm 8 weeks to respond first. If they respond sooner with a Final Response letter, you can escalate immediately. Don't wait the full 8 weeks if they reject your complaint.

What disputes can the FOS handle? +

Banking (accounts, loans, mortgages), insurance, investments, pensions, and most financial services. They cannot handle complaints about investment advice or large commercial disputes.

How long does the FOS take to decide? +

6 months on average, sometimes longer for complex cases. You'll be kept updated. The FOS can fast-track simple disputes.

Can the firm appeal an FOS decision? +

The FOS decision is binding on the firm but you can appeal in limited cases (procedural error, new evidence). You can also pursue court action, though at your own cost.

What if the firm doesn't pay an FOS award? +

The FOS decision is legally binding. If the firm doesn't pay, you can take them to court for enforcement. Contact the FOS for next steps.
