Field note · Advice & compliance
26% of UK adults trust ChatGPT for financial advice. The FCA counted.
On 6 July 2026 the FCA published the Mills Review, its long-term look at what AI does to retail financial services. Buried in the executive summary is the number every adviser should know: about a quarter of UK adults already trust a general-purpose chatbot for financial advice, and most of them do not know that nothing stands behind it.
The short answer
The FCA’s Mills Review (6 July 2026) found that around 26% of UK adults trust general-purpose tools such as ChatGPT, Claude or Gemini for financial advice, “despite limited awareness that formal routes to recourse will not apply”, and that one in five is open to AI making financial decisions for them. On the firm side, the Bank of England and FCA’s 2024 survey of 118 firms found 75% already using AI, a third of use cases bought in, and 46% of firms only partly understanding the AI they use.
Two regulators, two surveys, one uncomfortable pair of numbers. The first is what your clients are doing. The second is what your firm is doing. Neither is what the compliance manual assumes.
What did the FCA actually find?
The review commissioned a nationally representative survey of 5,026 UK adults in April 2026. Its executive summary reports that “around 26% trust general-purpose tools such as ChatGPT, Claude or Gemini for financial advice, despite limited awareness that formal routes to recourse will not apply”. It also reports that one in five UK adults is already open to AI making decisions for them, “with demand strongest where choices feel complex or high-stakes, particularly debt advice, pensions and investments”. The press release put the fifth at eleven million people.
Read that second sentence again. The appetite for handing a decision to a machine is strongest in exactly the areas — pensions, investments, debt — where regulated advice exists because the decisions are hard to undo.
What is the recourse gap?
Regulated advice from an authorised firm comes with the Financial Ombudsman Service and the Financial Services Compensation Scheme behind it. A general-purpose chatbot is not an authorised firm and does not give regulated advice; the review’s phrase is that formal routes to recourse “will not apply”. A client who acted on a chatbot’s suggestion about a pension transfer has nobody to complain to and nobody to compensate them. The review’s first recommendation, of seven, is to secure and adapt the regulatory perimeter — which is the regulator saying out loud that the line between a tool and an adviser is no longer where the rulebook drew it.
And what are firms doing?
The Bank of England and the FCA surveyed 118 firms in 2024 and published the results that November. 75% were already using AI, with another 10% planning to within three years. A third of all use cases were third-party implementations, and the top three providers accounted for 73% of cloud, 44% of models and 33% of data — the concentration that the review and the Treasury Committee both worry about. 55% of use cases involved some automated decision-making, though only 2% were fully autonomous. And 46% of firms reported only a partial understanding of the AI technologies they use, against 34% who said their understanding was complete.
The Treasury Committee, reporting on 20 January 2026, cited the same 75% and asked the FCA to publish comprehensive guidance on applying its existing rules to AI, including accountability under the Senior Managers and Certification Regime, by the end of 2026. It also asked the Treasury to designate the major AI and cloud providers as critical third parties by the same date; as of October 2025 no firm had yet been brought into that regime.
What this means for an advice firm
Three things follow, and none of them is “buy a chatbot”.
- Ask what the client has already been told. A quarter of adults trust a general-purpose tool; the fact-find should treat “I asked ChatGPT” the way it treated “I read it on a forum” — as a belief to be surfaced, dated and addressed in the suitability report, not ignored. The tool’s answer has no recourse; yours does, which is the whole of your value in that conversation.
- Know which of your own systems decides anything. Half of firm use cases involve some automated decision-making, and nearly half of firms only partly understand their AI. If a system in your firm scores, ranks, drafts or chases, somebody should be able to say what it did, from what inputs, and who confirmed it. In a regulated firm the audit trail is the product, and the SM&CR question the Committee wants answered is “who was accountable for that decision?”
- Expect the rules to be written for you if you do not write them first. The Committee has asked for guidance by the end of 2026; the review has asked for the perimeter to move. A firm that can already show what its AI does, where a human sat, and what it refused to do will find that guidance describes what it already does. That record is a thing you can build now.
The client-side number will not go down. The firm-side number will not go down either. What changes is whether, when a client asks why they should pay for advice a chatbot gave them for free, the answer is a sentence about recourse and a file that proves it.
Questions people actually ask
What is the FCA Mills Review?
A long-term review, led by FCA executive director Sheldon Mills and published on 6 July 2026, into how artificial intelligence will reshape retail financial services by 2030. It drew on a survey of 5,026 UK adults in April 2026 and made seven recommendations, the first of which is to secure and adapt the regulatory perimeter.
How many people use ChatGPT for financial advice in the UK?
The Mills Review reports that around 26% of UK adults trust general-purpose tools such as ChatGPT, Claude or Gemini for financial advice, “despite limited awareness that formal routes to recourse will not apply”. It also found one in five adults open to AI making financial decisions for them, strongest for debt advice, pensions and investments.
Is advice from ChatGPT covered by the Financial Ombudsman or FSCS?
A general-purpose chatbot is not an authorised firm giving regulated advice, so the formal routes to recourse that apply to regulated advice — the Financial Ombudsman Service and the Financial Services Compensation Scheme — do not apply to it. The Mills Review’s own wording is that such routes “will not apply”, and that most people who trust these tools are not aware of that.
What percentage of UK financial services firms use AI?
The Bank of England and FCA survey published on 21 November 2024 found 75% of the 118 firms surveyed already using AI, with a further 10% planning to within three years. A third of use cases were third-party implementations, 55% involved some automated decision-making, and 46% of firms said they had only a partial understanding of the AI they use.

The record is the difference between you and the chatbot.
We build the systems around advice — the fact-find chase, the first draft, the pack — with six records for every action: trigger, inputs, output, who confirmed it, what they changed, and what it refused to do. When a client asks why they paid for advice, or a regulator asks who was accountable, that file is the answer.
