Complain to the firm in writing first: it has up to eight weeks to issue a final response. If you are unhappy, or that deadline passes, escalate free of charge to the Financial Ombudsman Service, normally within six months. The Ombudsman can order redress of up to £430,000.
The short answer
- Always complain to the firm in writing first: it has up to eight weeks to give a final response.
- If unhappy, escalate free to the Financial Ombudsman Service, normally within six months.
- The Ombudsman can make a binding award of up to £430,000 based on your actual loss.
If a regulated adviser has let you down, through poor advice, unclear charges, or simply bad service, you have a clear, free and well-worn route to put it right, and you are far from powerless. The UK complaints system is deliberately weighted in the consumer’s favour: the firm must investigate properly, and if it does not satisfy you an independent ombudsman can step in and order redress. The key is to follow the steps in order. This is general information, not personal advice.
Almost every complaint follows the same two-stage path. First you complain to the firm itself, which is legally obliged to handle it fairly and reply within a set time. If that does not resolve matters, you escalate, for free, to the Financial Ombudsman Service, an independent body whose decisions bind the firm. Only where a firm has actually collapsed does a third route, the compensation scheme, come into play.

The complaint process, step by step
- 1
Complain to the firm in writing
Set out clearly what went wrong, when, and what you would like done, a refund of fees, compensation for loss, or a corrected recommendation. Keep it factual and keep a copy. Writing, rather than phoning, creates the paper trail that matters later.
- 2
Give the firm up to eight weeks
The firm must acknowledge your complaint promptly and issue a “final response” within eight weeks. That response should explain its decision and tell you about your right to go to the Ombudsman if you remain unhappy.
- 3
Escalate to the Financial Ombudsman Service
If you are dissatisfied with the final response, or eight weeks pass without one, refer the complaint to the Ombudsman, normally within six months of the firm’s final response. It is free, and you deal with them directly.

Claim from the FSCS if the firm has failed
If the firm is insolvent and no longer trading, the Ombudsman cannot help. Instead claim through the Financial Services Compensation Scheme, which can pay up to £85,000 per person for bad investment advice.
That sequence resolves the overwhelming majority of complaints. The single most useful thing you can do at the outset is to gather your evidence, the suitability report, fee agreements, illustrations, and any emails, because a complaint supported by dated documents is far harder to brush aside. Before you begin, it is also worth confirming the firm is authorised at all, which our answer on what an adviser should have explains how to check on the FCA Register.
Who handles what, and what it costs you
The three bodies involved in a UK adviser complaint
| Body | When it applies | Cost to you | What it can do |
|---|---|---|---|
| The firm | Always, the first port of call | Free | Investigate and offer redress within eight weeks |
| Financial Ombudsman Service | If the firm fails to satisfy you | Free | Make a binding award of up to £430,000 |
| Financial Services Compensation Scheme | If the firm has gone bust | Free | Pay up to £85,000 per person for bad advice |
| The FCA | To report misconduct (not for redress) | Free | Supervise and discipline firms, not compensate you |
Notice a common thread: every legitimate route is free. You never need to pay a claims-management company a slice of your compensation to do what you can do yourself in an afternoon. The Financial Conduct Authority is worth mentioning too, but for a different reason: you can report an adviser’s misconduct to the FCA, and doing so helps protect others, but the FCA does not award you personal compensation. For that, the Ombudsman and the compensation scheme are your channels.
Mind the six-month deadline
Once a firm sends its final response, you normally have just six months to take the complaint to the Financial Ombudsman Service. Miss that window and the Ombudsman may refuse to consider it. If in doubt, refer early: you can always withdraw, but you cannot easily revive a time-barred complaint. This is information, not personal advice.
Giving your complaint the best chance
A well-made complaint is specific about the harm and the remedy. Rather than “I am unhappy with my adviser”, say what was wrong, for example, that a product was unsuitable for your stated attitude to risk, or that charges were never clearly disclosed, and what you want to happen. Attach the evidence, put a date on everything, and keep your tone measured. Ombudsman decisions turn on whether the advice was suitable and whether the firm acted fairly, so framing your complaint around those questions helps enormously.
It also helps to know that complaining is ordinary and expected; the system exists precisely because things sometimes go wrong. Firms deal with complaints as routine, and a fair one has every incentive to resolve yours quickly rather than let it reach the Ombudsman. If your experience has left you wary of the whole profession, remember that the vast majority of UK advisers are competent and straight: the fuller picture of what good and bad look like is set out across our guides to choosing an adviser, and our answer on choosing a trustworthy adviser can help you start again on a firmer footing.
