UK ISAs Market Report 2025

"Falling interest rates and changing regulations are enhancing the appeal of stocks and shares ISAs. However, providers must help savers overcome their aversion to risk."

UK ISA Market – Trends and Insights

  • The cash ISA segment has seen record growth over the past year in the UK ISA market, but market conditions are now shifting in favour of stocks and shares ISAs, driven by a downward trend in the base rate and government efforts to stimulate retail investment activity.
  • A potential reduction in the annual cash ISA allowance could encourage more investment in stocks and shares ISAs, with 74% of cash ISA holders under 35 indicating they would be motivated to invest more.
  • Despite the recognised value of ISAs, many consumers still perceive them as overly complex. While new rules have made ISA savings more flexible, further simplification is needed for the market to reach its full potential.
  • The rise of zero-fee or ultra-low-cost FinTech ISA providers is making stocks and shares ISAs more accessible and less intimidating, helping to expand the market.
  • These digital platforms, equipped with fully integrated tools and features, are educating and guiding investors to make informed, personalised decisions. AI is expected to play a key role in enhancing these platforms with even more customised guidance.

This Report Looks at the Following Areas:

  • The short-, medium- and long-term impact of the economic and regulatory environment on ISAs
  • How digital commission-free providers, like Trading 212 and Robinhood, are transforming the ISA market
  • Key factors driving the choice of ISA provider and current ISA owner saving and investment intentions over the next year
  • How a potential reduction in the annual cash ISA contribution limit would impact saving and investment behaviour
  • Consumer preference for penalty-free withdrawals and low transaction fees when choosing an ISA provider
  • The level of consumer understanding when it comes to ISA benefits and whether consumers actively check the progress of their ISA investments

What goes into a Mintel Market Intelligence Report?

Curious about how a Market Intelligence report comes together? We like to think of it as building a detailed puzzle. We start with individual pieces: data from consumers, market statistics, industry trends, and online conversations. Then our expert analysts add world-class human insight and industry knowledge. The pieces are assembled to reveal a clear, comprehensive picture of a market.

The Four Pillars of Our Research

We use a combination of four main research methods when creating our reports, each adding a valuable perspective:

  • Consumer Research: Direct surveys with real people, giving us clear, current insights into what people think and do.
  • Desk Research: In-depth review of trusted data sources. We use this rich database, plus powerful internal tools that track new products and market sizes, to detect trends and guide forecasts.
  • Trade Research: Insights from conversations with industry experts. Their real-world experience helps us understand what’s happening behind the scenes.
  • Brand and Social Media Research: Analysis of online opinions and trends. This lets us spot trends, measure brand sentiment, and capture feedback in real time, adding further depth to our research.

For further information about our research and analysis methods, visit our helpdesk.

Bringing It All Together

Each of these four pillars provides a different piece of the puzzle. Consumer research tells us what customers think, desk research provides the factual framework, trade research offers an insider’s view, and social media analysis reveals public sentiment.

Our expert analysts are skilled in weaving these diverse data streams together. They apply a range of quantitative and qualitative analysis techniques to uncover the deeper story, connecting the dots to deliver clear, actionable insights. This comprehensive, multi-layered process is how we transform raw data into a market intelligence report you can trust to inform your most important business decisions.

We use Mintel Reports, mostly for financial services and ecommerce markets, plus a few retail and technology ones.

As a leading payments provider, we value additional insights into consumer behaviour, opinions and trends that are shaping the many different markets we operate in. Mintel is a very good and very quick way for us to obtain those insights.

We use Mintel to get a view on where a particular market is going, which can support us in product development and help us identify opportunities or indeed risks, it is a very useful barometer of a market’s potential.

Mintel helps us when we want to know something quickly – it provides fast answers to our questions. If we need to get a view of what’s going on in a particular market it’s very useful.

When carrying out background research, I find Mintel an excellent starting point.

The fact that it covers so many markets is a big plus for me– instead of having to buy specialist products in each area we are interested in, especially when we only require a brief view on a particular market, we can go to Mintel for help as a one-stop shop. I find Mintel a useful and valuable resource.

Ben Zeidler, Director - Research and Analytics, Tenth Wave

Mintel is really good for getting a handle on a particular category quickly. If we are working on a new business pitch in an area we don’t have much experience in, it’s a brilliant way to get up to speed with what’s going on, what’s changing and what the key trends are in any category.

It’s very rare now that anyone will plough through a 200-page report – that’s why the summaries are really useful. We know they are backed up by a lot of detail, so if you need to go into something in more depth you know the information will be all there for you.

Pauline Robson, Managing Partner, Mediacom

We have such a great working relationship with Mintel on lots of different levels. As an insight partner, they have helped us to develop our business planning in specific categories as well as supporting our creative process but they’ve also been super helpful with facilitating our events in their inspirational offices near St Paul’s.

They’re an innovative company, with a client-focused team that always delivers.

Working in a customer-obsessed organization means that data and insights have to be at our fingertips. Mintel’s reports help us support anecdotes with real quantifiable insights. The summary sections (which I really like) helps save time by giving a birds eye view of the content before spending time combing through the pages.

Our business review discussions are strengthened by the relevancy of the reports to help us better understand our customers. In addition, the customer service received from the team (especially in crunch periods) makes the process of understanding customer behavior even better.
