Financial Ombudsman Service vs County Court Claim

Should you take your complaint to the Financial Ombudsman Service or issue a claim in the County Court?

Overview

When a bank, insurer, or financial services firm has treated you unfairly, you have two main routes to redress: the Financial Ombudsman Service (FOS) and the County Court. The FOS is a free, informal adjudication service established under the Financial Services and Markets Act 2000. The County Court is a formal court process. The two routes are not always mutually exclusive, but pursuing one often affects your strategy for the other.

Side-by-Side Comparison

Financial Ombudsman Service (FOS)

Cost: Free

Time: 3 months–2 years depending on complexity

Pros

Completely free for consumers — the firm pays a case fee regardless of outcome
Informal process — no legal knowledge required; the investigator does the work
Can award up to £430,000; also directs firms to take specific remedial action
Decisions are binding on the firm if the consumer accepts them

Cons

Only covers regulated financial firms and certain regulated activities
Can be slow — complex cases can take 1–2 years
If you accept the award, you cannot then go to court for more
The FOS cannot award legal costs even if you used a solicitor

Best For

Complaints about banks, insurers, mortgage lenders, investment firms, debt collectors, and other regulated financial services businesses — particularly where the value is under £100,000.

County Court Claim

Cost: £35–5% of claim value in court fees; legal costs if represented

Time: 3–12 months

Pros

No upper limit on the amount you can claim
Legal principles strictly applied — stronger on points of law
Faster for straightforward claims (judgment in default if no defence filed)
If successful, judgment is immediately enforceable

Cons

Court fees apply (5% of claim value for claims between £5,000 and £10,000; higher percentage below)
You bear the risk of adverse costs above the small claims threshold
Requires legal knowledge or representation for complex cases
Enforcement is your responsibility — a judgment does not guarantee payment

Best For

Claims over £430,000, cases where the legal point is clear-cut and a quick default judgment is likely, or where the firm is not covered by the FOS.

Our Recommendation

For most financial services disputes, start with the FOS — it is free, the investigator does most of the work, and awards up to £430,000 are binding on the firm. Only consider court proceedings if the FOS is not available (e.g. the firm is not regulated or the matter falls outside FOS jurisdiction), if you believe the legal argument is very clear-cut, or if the claim value exceeds the FOS cap. Do not accept a FOS award if you plan to go to court — acceptance is final.
