Had a bank, insurer, mortgage lender or credit company treat you unfairly and their complaint response didn't put things right? The Financial Ombudsman Service can investigate and make a decision the firm is legally required to follow. It's completely free and you don't need anyone to represent you.
The firms it covers are broad. Banks and building societies. Home, car and travel insurers. Mortgage lenders. Credit card companies. Pension providers. Investment firms. Payday lenders. Debt collection firms. Hire purchase companies. Most regulated financial businesses in the UK fall within its jurisdiction. If a regulated firm has made an error that cost you money, applied charges it shouldn't have, refused a valid claim, or given you misleading information when you took out a product, the Ombudsman can look at it.
Two things matter before you submit. First, you must have complained directly to the firm and given them eight weeks to respond. If they haven't responded in eight weeks, you don't have to wait any longer. If their response doesn't resolve things, you then have six months from the date of that response to go to the Ombudsman. That six-month deadline is strict. Miss it and they may not be able to help.
One more thing worth saying clearly. Claims management companies will offer to handle this for you and take a percentage of anything you receive. Don't use them. The Ombudsman has said explicitly that using a CMC doesn't improve your chances of success. It only reduces what you get if your complaint is upheld. The process is designed to be used directly by consumers, without any professional representation.
We've written a free complete guide covering who the Financial Ombudsman can help, the time limits you need to know, a full worked example complaint letter you can adapt for your own situation, what happens after you submit including the investigator's view and the final decision process, and the common reasons the Ombudsman can't help so you can check eligibility before you write.
If a financial firm has let you down and their response wasn't good enough, this is your next step. Please share it with anyone who needs it.
