How to complain to an investment firm, in writing.

The complaint is not a conversation. It is a document that starts a clock, creates a record, and decides what the Ombudsman will have in front of it later. Write it that way.

Short answer

Put the complaint in writing, name the product and the date, set out what you were told, and ask for the advice file. Firms must normally give you a final response in writing within 8 weeks, and you then have 6 months from that response to take the complaint to the Financial Ombudsman Service.

Indicators only. Not legal or financial advice. Not a prediction of outcome.

The seven things every complaint needs

A complaint that answers these questions in order is easy to investigate, and investigations that are easy tend to move. Keep it factual, keep it short, and number the documents you enclose.

  • Who you are, and the account or policy numbers involved
  • What you were sold, in one sentence, and the date
  • Who sold it to you, and in what capacity
  • What you were told, and what you say you were not told
  • Why you say it did not suit you at the time
  • What you are asking the firm to do
  • Your request for the advice file: fact find, attitude to risk record, recommendation and charges disclosure

Ask for the file at the same time

You do not have to wait for the outcome to ask what the firm has. Ask in the same letter for the documents it holds about the advice, and put a date by which you would like them. Firms are expected to keep records of the advice they give; a firm that cannot produce them has told you something useful.

What the firm has to do

The FCA’s rules require firms to deal with complaints fairly, consistently and promptly. Unless the complaint is resolved within three business days, the firm must acknowledge it in writing. It must normally give you a final response in writing within eight weeks, telling you whether the complaint succeeded or why it needs more time. If it does not, you can go to the Ombudsman without waiting further.

Reading the response

Look for three things: whether it says the advice was suitable and why; whether it addresses the specific documents you sent; and the date on the letter. The date matters because it starts the six months you have to refer the complaint to the Ombudsman. If the letter contains no reasoning, say so, in writing, and ask again.

If the answer is no

A rejection is not the end. The Ombudsman decides what is fair and reasonable, and it frequently reaches a different view from the firm, particularly where the firm’s own file does not support its account. Refer the complaint within six months of the final response, and send the whole file again rather than a summary.

If you use someone to help

You do not need to. Complaining to a firm and to the Ombudsman is free and designed for consumers. If you do appoint a claims management company, understand the FCA’s fee cap for financial services claims — between 15% and 30% of the award depending on its size for claims started on or after 1 March 2022 — and note that it must give you a one-page summary before you sign, a cost illustration, and a 14-day cooling-off period.

FAQ Questions

The questions this guide answers.

Can I complain by phone?

You can, but put it in writing as well. What a firm records on a call is not the same as what you wrote, and the written version is what the Ombudsman will read years later.

How long does the firm have?

It must normally give you a final response in writing within 8 weeks of your complaint, unless it resolves the complaint within 3 business days.

Do I have to use the firm’s own complaints form?

No. A letter or email setting out the facts is a complaint. Using the firm’s form can help it log the date, so if you send a letter, ask for written confirmation that it has been treated as a formal complaint.

What if the firm ignores me?

After eight weeks without a final response you can take the complaint to the Financial Ombudsman Service without waiting for one. Do not let the deadline pass while waiting for a reply that is not coming.

Should I mention the Ombudsman in my complaint?

It is fine to say that you will refer the complaint if it is not resolved. What matters more is the factual content, and asking for the advice file.
