Financial Ombudsman or court: which route for a complaint

If a bank, insurer, lender or investment firm has turned down your complaint, you have two realistic routes: the Financial Ombudsman Service, which is free and does not need a lawyer, or the courts. The ombudsman can require a business to pay up to £455,000 for complaints referred on or after 1 April 2025 about acts or omissions on or after 1 April 2019¹. Court has no such cap, but it carries fees, deadlines and the risk of paying the other side's costs.

The two routes are not usually open at the same time in the way people assume. You normally have to complain to the business first and give it up to eight weeks to answer². Once you have a final response, you have six months to bring the complaint to the ombudsman³. If you accept the ombudsman's final decision, it becomes legally binding on both sides and it is unlikely you could then take the same business to court for more compensation¹.

The choice matters most when the amount at stake is large, when the complaint is about something the ombudsman cannot look at, or when you may want to keep the court option open. This page sets out how each route works, what it costs, what it can award, and where the protections stop.

Complain to the business first: the eight-week rule

The ombudsman is a second-stage route, not a first one. Before it will take a case, you have to make a formal complaint to the company involved. If the business does not send a final response letter within eight weeks, or you are unhappy with the response it does send, you can bring the complaint to the ombudsman⁷. The eight-week maximum is long-standing: a firm has a maximum of eight weeks to try to resolve a complaint⁸.

There is one exception. The ombudsman can look into a complaint before eight weeks have passed, but only if the business and its customer both agree⁴. In practice that is rare, because a firm has little reason to shorten its own window.

The final response letter itself has to do a specific job. Under the complaints rules, it must inform the complainant that if they remain dissatisfied with the response, they may now refer the complaint to the Financial Ombudsman Service⁹. That sentence is what starts your six-month clock, so it is worth keeping the letter and noting its date.

The rules are not identical for every complainant. For small businesses, the rules are different depending on whether what you are complaining about happened before or after 1 April 2019¹⁰. The ombudsman can also look at complaints made by small and medium-sized enterprises about financial firms, and at complaints made by customers of claims management companies¹¹.

The Financial Ombudsman is free and needs no lawyer

Bringing a complaint to the ombudsman is straightforward and will not cost you anything⁵. The service describes itself as free and easy to use¹². You do not need a lawyer or anyone else to represent you². Unlike a court, you generally do not need anyone to represent you, and if you would prefer, the ombudsman can talk to a member of your family, a friend or someone else who is helping you¹³.

That matters because the alternative route is not free. Court claims carry issue fees and, in some tracks, the risk of an adverse costs order. The ombudsman route carries neither. You can submit a complaint online or over the phone², and the ombudsman publishes a complaint form to fill in¹⁴.

You also do not need to pay a claims management company. The ombudsman states plainly that you do not need to pay anyone to represent you, for example a lawyer or claims management company³. Claims managers have historically handled a meaningful share of cases: 26% of complaints in the year ended 31 March 2009 were made on behalf of consumers by claims management companies¹⁵, and by 2015/16 claims managers brought 61.5% of packaged bank account complaints¹⁶. A claims manager typically takes a cut of any award, which reduces what reaches you.

What the ombudsman can award: up to £455,000

The ombudsman's award limit is the maximum amount it can require a financial business to pay when it upholds complaints¹⁷. The limit depends on when the complaint was referred and when the act or omission happened:

The limit has risen over time. Earlier figures the ombudsman has published include a maximum money award of £150,000, or £100,000 for complaints received before 1 January 2012¹⁸, and a power to tell a business to pay a specific amount of money up to £150,000¹⁶. The ombudsman has also said it can order a business to put matters right and pay compensation of up to £150,000¹⁹.

Beyond money for a direct loss, the ombudsman can award compensation for distress and inconvenience. Its guidance gives figures of up to £1,500 in one context²⁰ and up to £5,000 in another²¹. In one case study, the ombudsman said that due to the extreme level of impact caused to both policy holders over many years, it thought an award of £8,000 overall was appropriate²².

The ombudsman decides cases on relevant law and regulations, the regulator's rules, guidance and standards, industry codes of practice and, where appropriate, good industry practice¹⁴. Where it finds a business treated a customer unfairly, it will tell the business to put the customer back where they would be if the mistake had not happened, and possibly make an award for distress and inconvenience²³.

Accepting a final decision usually closes the door to court

This is the single most important difference between the two routes. If you accept an award made in a final decision, it is unlikely you will be able to take the business to court for more compensation later¹. Accepting any compensation may mean you cannot pursue the business in court for the same complaint¹³. The ombudsman repeats the point in its own consumer guidance: accepting compensation may mean you will not be able to take the business to court for the same complaint²⁴.

The reason is that acceptance turns the decision into something stronger than advice. If the complainant accepts the final decision, it becomes legally binding for both parties²⁵. Final determinations, once accepted by the complainant, are binding on both the complainant and the respondent firm²⁶. If the complainant accepts, the decision and any redress awarded become binding on the firm²⁷.

The flip side is what happens if you do not accept. If the consumer accepts an ombudsman's decision within the time limit specified, both the consumer and the firm are bound; otherwise the firm is not bound but the consumer remains free to take court proceedings²⁸. An ombudsman's final decision is legally binding if you accept it, and enforceable in court²⁹.

So the decision point is real. Accepting secures the award and closes the argument. Rejecting keeps the court option alive but gives up the certainty of the ombudsman's award.

Court time limits keep running while the ombudsman looks at your case

There is a trap here that catches people who assume the ombudsman process pauses everything else. There are time limits on taking a case to court, and these continue to run while the ombudsman handles your case¹. Waiting months for an ombudsman decision does not extend the period in which you could have issued a court claim.

That means the two clocks run in parallel. The ombudsman clock is short and clear: you will need to make a complaint to the ombudsman within six months from the date on your final response³. The court clock depends on the type of claim and is not set by the ombudsman. Where a limitation dispute arises, the ombudsman will take into account the regulator's rules on time limits, and any contact that has been made in the meantime³⁰.

If you think your complaint may end up in court, the practical consequence is that you may need to take advice on the court deadline before the ombudsman has finished, rather than after. The ombudsman cannot extend a court time limit, and accepting its decision later will not revive one that has expired.

Ombudsman or court: how each route suits different complaints

The ombudsman route is designed for disputes about financial products and services where the facts are contested and the sums are moderate. It covers banking and payment services including current accounts, savings accounts, direct debits, money transfers, electronic payment platforms, cheques and banker's drafts²³. It resolves complaints about issues such as account closures, disputed transactions, IT failures and problems with switching services²³. On the credit side, it covers payday loans, the affordability of lending, quality of goods bought or hired with credit, and other types of lending including mortgages³¹.

The process has two stages. An investigator looks at the case first. If one or both sides disagree with the investigator's view, they can ask for the complaint to be referred to an ombudsman, who takes a fresh look including any new evidence¹³. The ombudsman considers facts and evidence from both the business and the customer, then sets out findings explaining the decision and what needs to be done to put things right³¹.

Court suits different situations. It is the route for a claim the ombudsman cannot consider, for a sum above the award limit where the claimant wants a binding order rather than a recommendation, and for cases where the legal issue is genuinely contested. It is also the only route left once a final decision has been rejected, because if you are not happy with the ombudsman's final answer, it cannot help you any more, but you can take your complaint to court if you want¹².

Tax and interest on compensation

Interest is where an ombudsman award can grow beyond the headline figure. For complaints referred before 1 January 2026, the ombudsman typically asks financial businesses to use a rate of interest at 8% simple a year. From 1 January 2026, it typically asks businesses to calculate this using a time-weighted average of the Bank of England base rate plus one percentage point¹.

There is a separate rate for late payment. If a business fails to pay by the specified payment deadline, interest is applied at a default rate of 8% simple³². The interest rate for late payment is usually 8% simple a year¹. The deadline is usually 28 calendar days from the date the ombudsman informs the financial business that you have accepted the final decision¹.

One useful detail: if you were awarded interest for being deprived of money because the business delayed payment, that interest payment can be awarded on top of the limit¹. So the cap applies to the compensation, not necessarily to everything the business ends up paying.

On tax, the ombudsman's published guidance on compensation does not set out a tax treatment, and this page does not give tax advice. What the ombudsman does say is that it may tell a business to pay compensation for distress or inconvenience suffered³³, and in one case it told an insurer to pay a claim and apply interest from the date of the injury until the date of settlement³⁵. Where a complaint is about a group scheme, any award will go to the employer as the policyholder rather than to the individual³⁶.

What happens if the business doesn't pay what the ombudsman told it to

An accepted final decision is not a suggestion. It is legally binding on the firm and enforceable in court²⁹. The statutory backing is in the Financial Services and Markets Act 2000, Part XVI³⁷. If a person fails to comply with a requirement imposed under section 231, the ombudsman may certify the failure to the court, which may treat the defaulter as in contempt³⁸.

In practice, payment is expected quickly. The usual deadline is 28 calendar days from the date the ombudsman informs the business that you have accepted the final decision, and late payment attracts interest at 8% simple a year¹. If the ombudsman finds that a business has not applied a redress scheme's rules correctly, it will set out what the business needs to do next³⁹.

There is a limit on what the ombudsman can compel. If it thinks compensation should be higher than its award limit, it can recommend that the financial business pays more, but it cannot make the business pay anything over the limit¹³. It can recommend a higher payment if it thinks that is fair, but the business does not have to accept that recommendation¹. The legislation reflects the same split: a money award may not exceed the monetary limit, but the ombudsman may recommend that the respondent pay the complainant the balance³⁸.

Where to get free help

The ombudsman's service is free and you do not need to pay anyone to represent you³. If you would prefer, it can talk to a member of your family, a friend or someone else who is helping you¹³. Businesses and consumer advisers can contact the ombudsman's Business Support Hub for information on how a complaint might be looked at and guidance on the rules³¹.

For pensions specifically, there is a separate route: the Pensions Ombudsman publishes guidance on where to go for help with a pension complaint²⁹. For general money guidance, MoneyHelper covers topics such as credit union current accounts⁴⁰ and basic bank accounts⁴¹. If your complaint is about a firm's conduct rather than your own loss, the Financial Conduct Authority handles that separately, and there is a route for complaining about the FCA, PRA or Bank of England.

Before you complain about a firm, it is worth checking it is authorised. The ombudsman's guidance points consumers to the Financial Conduct Authority's Firm Checker to confirm a firm is authorised and to help avoid scams²³. If your complaint is about a scam payment, the ombudsman has dedicated guidance on scams involving unauthorised payments and identity theft and on scams where you were tricked into making a payment.
