New STRAT7 research reveals that 55% of UK adults now use AI platforms for financial questions. Here’s who they are, what they’re asking, and what it means for brands trying to reach them.

At a glance

In April 2026, STRAT7’s nationally representative consumer study found that 55% of UK adults now use AI platforms for financial questions. ChatGPT scores higher than paid financial advisors on satisfaction (76% versus 72%) but lower on trust (53% versus 92% for bank websites). Among the 40% of AI financial users who have asked for investment guidance, the average amount invested on the back of an AI answer is £2,350.

Key statistics

  • 55% of UK adults use AI for financial questions.
  • 76% satisfaction with ChatGPT for financial advice, ahead of paid financial advisors at 72%.
  • 53% trust in ChatGPT for financial information, against 92% for bank websites.
  • £2,350 average invested on the back of an AI answer, among the 40% of AI financial users who have asked for investment guidance.
  • 45% of Millennials and Gen Z take most of their financial questions to AI; 72% of Boomers have never used AI for a financial question.
  • £69,475 average household income of AI financial users, against £34,841 for non-users.

Across our own research into UK consumers, we keep hearing the same thing: “I just asked AI.” What started as a niche behaviour among the digitally confident has crossed into the mainstream. More than half of UK adults now turn to AI platforms when they have a financial question, and they’re broadly satisfied with the answers they’re getting.

Martin Lewis, one of the most trusted voices in the country, is even encouraging it. He recently published ChatGPT prompt advice for young adults to calculate whether they should repay their student loan, because the maths has genuinely become too complicated to explain any other way.

Key findings

Who is using AI for financial advice?

  • Younger, higher-earning consumers with complex financial lives. AI financial users have an average household income of £69,475, nearly double the £34,841 average of non-users.
  • 35% are young families, compared with just 7% of non-users. They’re more likely to bank with a neobank, invest in crypto, and own stocks.
  • There is a generational gap. Nearly 45% of Millennials and Gen Z take most of their financial questions to an AI platform. But among Boomers, 72% have never used AI for a financial question at all.

What are they actually asking?

We asked consumers the last financial question they put to an AI platform. Three goals emerged: they want quick wins (shorter-horizon, actionable goals), personalisation (sharing their own numbers and expecting tailored answers), and guidance rather than information.

  • 55% of their questions start with the word “How.” As well as searching for facts, they are asking AI for informed direction.
  • The single most common topic is investment advice.
  • 40% of AI financial users have asked for investment guidance, and the average amount invested among that group is £2,350. It is worth pausing on that. Real money is being committed on the basis of what AI says.

Where does AI sit alongside banks and advisors?

ChatGPT (48%) now sits just three points behind paid financial advisors (51%) as a source for financial questions. On satisfaction, it is already ahead: 76% versus 72%. Only bank websites and Money Saving Expert score marginally higher.

But trust tells a different story. ChatGPT scores 53% on trust for financial information, versus 92% for bank websites and 86% for Money Saving Expert. 

What should financial brands do about this?

The gap between satisfaction and trust is the opportunity. People are getting answers they’re happy with from AI, but they’re not yet willing to fully rely on it for high-stakes decisions.

The opportunity? The brand that figures out how to combine the instant, personalised, always-available nature of AI with the institutional trust of a regulated provider will own the next generation of financial customers.

Our research points to four priorities:

  • Lean into growth, because AI users are more open to higher-reward products and providers who challenge conventional thinking.
  • Build for personalisation, because generic content cannot compete with tailored AI responses.
  • Design a hybrid AI and human model, where AI handles the first line of guidance and humans step in for complexity.
  • Market to both the end-user and the AI platform, because your brand is increasingly being introduced to customers by an AI summary before a human ever sees your homepage.
