How the FCA uses sandboxes to dig out AI fintech solutions
The parent of this play area is the City regulator, the Financial Conduct Authority (FCA), and it allowed Zilch, and the dozens of other fintech firms that took part, to play around, or experiment, without causing consumers any harm or falling foul of any regulations.
Zilch's rapid rise since illustrates the valuable role that regulators can play to encourage innovative start-ups to disrupt existing markets with new approaches. Sandboxes are also a vital tool in the armoury of policy makers in their attempts to protect Britain's competitive edge in fast-moving sectors, ranging from life sciences to space exploration.
After using the sandbox for 12 months, Zilch launched in 2020 with a licence from the FCA and has since been used by over 4.5 million customers. Desmond McNamara, its chief risk officer, said: 'The sandbox programme allowed us to go through that process of regulation whilst we were building the business. If we had to build the whole business, then apply, it would have been harder.'
The FCA has doubled down on its approach with financial services, launching last month what it has called a 'supercharged sandbox' to help facilitate the rapid introduction of AI-powered financial services.
In essence, a sandbox gives technology companies a controlled environment to test systems safely. In the case of the AI sandbox, announced last month, the FCA is letting businesses test AI applications such as fraud detection, real-time credit scoring and enhanced customer service. Companies use dummy data created by the FCA, such as fake card numbers and bank account details, and also have access to computing power that they might not otherwise be able to afford. The FCA has struck a deal with the chipmaker Nvidia to provide access to its data centres and also some of its software. The application period is now open and the first companies are expected to start experimenting in October.
Alex Kirkhope, partner at Shoosmiths, a law firm which advises companies on how to use sandboxes, said: 'It's a space that allows businesses, especially smaller businesses, the ones who don't have the infrastructure or the access to computing power, to be able to do that themselves, whether they're developing those systems themselves or whether they are looking to deploy them and understand how they operate.'
Kirkhope said it was significant that Nvidia has chosen to partner with the regulator on this project. 'Their chips are some of the most advanced processing that exists in the world today. Their involvement, investment and interest in the UK economy and UK fintech space has to be seen as a positive because if they weren't talking to us, they would be talking to China, US, and probably other major European nations,' he said.
McNamara from Zilch said the sandbox was particularly attractive to start-ups, which are typically still learning what they can do and what the regulator will allow them to do. 'The regular authorisation process is more naturally tailored to firms who are already authorised and they were adding to their authorisation,' he said. 'Whereas the regulatory sandbox allows firms who are starting out, because there is a more natural startup culture, you don't have to come with the answer to everything at the start, it's much more of an interactive process.'
Francesco Fulcoli, the chief compliance and risk officer at Flagstone, a savings platform, is one of those considering using the new testing environment. Flagstone already manages £16.2 billion in people's savings and it is hoping to use the FCA sandbox to test its use of AI for customer support, anti-money laundering and a fully automated process for new customers starting an account. 'Working with many other regulators across the globe, this was a good move. Not many regulators are going that direction,' he said. 'I think it's a good step ahead and will help the fintech environment to keep growing in the UK.'
Nicky Goulimis, co-founder of Tunic Pay, a fintech company that helps banks stop fraudulent bank transfers, is another hoping to use the sandbox to help build out its AI. Goulimis said she was particularly encouraged by the FCA's inclusion of agentic AI, which uses reasoning to autonomously make decisions and perform tasks.
'It's going to massively encourage innovation because it's unlocking new use cases that would otherwise not be possible. My interpretation is that this is the FCA saying, we are open for business around agentic systems, which has historically not been the perspective,' said Goulimis.
Tunic Pay has already started using AI and is hoping access to the sandbox will help the company collaborate with the government and 'push the imagination' of what can be done with AI agents for scam detection and prevention.
• Mandelson wants the UK to make a tech 'moonshot'. Can we do it?
Financial services is not the only area of the economy where regulators are using sandboxes to let startups experiment. The Department for Science, Innovation and Technology has funded sandboxes to help industry and academics work on wireless technology, engineering biology and novel space activities.
Kirkhope said the latest AI sandbox is just one piece of the puzzle for harnessing AI. 'The government needs to invest in and encourage the build-out of AI infrastructure, particularly compute and data processing, data centre capacity within the UK. And I don't think we should underestimate that challenge. Unless it all works together, we can only get so far,' he said.

Blairs' discount designer clothes deal caused No 10 concern, files show
Ex-Prime Minister Tony Blair and his wife Cherie received tens of thousands of pounds in discounts on designer clothing while in Downing Street, documents July 2001 and December 2002, Mrs Blair bought clothes worth more than £75,000 – equivalent to £150,000 today – but paid just £31,000 for them, newly released papers from the National Archives Street officials were worried these benefits would have to be declared under a new ministerial code, which was then coming into effect, and advised the Blairs to repay thousands of is not clear from the papers if this happened. From fashion designer Nicole Farhi alone, Mrs Blair bought clothes worth nearly £21,000 for herself and the prime minister, paying just over £8, also had substantial discounts from Burberry, James Lakeland, Ungaro, Joseph, and Maria Grachvogel, amongst "wholesale" discounts had been negotiated by Carole Caplin, Mrs Blair's trainer and personal Tony, who was prime minister between 1997 and 2007, also benefited from a 25% discount from Paul Smith, famous for his freshly released documents reveal how the optics of the discounts and spending was a concern for Downing Street officials at the time."In terms of public perception," wrote No 10 private secretary Clare Sumner, "the amounts involved are quite large".Along with the cabinet secretary, she recommended that the Blairs should pay back part of the discount, though Cherie was entitled to divide her purchases into two, on the basis that half the clothes were required for her role as a "career woman".They would say the Blairs had "commercial terms" from the designers, which were usually a discount of about 10 or 15%.She suggested other options, including saying that Mrs Blair had the same treatment as other high profile individuals with a personal shopper, and that she needed the clothes for public engagements of her said Mrs Blair sometimes gave her outfits to charities or exhibitions after use: "So it is difficult to see how anyone could seriously allege she is acquiring a clear personal benefit out of your position as PM." According to the memo, the discounts had been in place for several years, and dated back to before Sir Tony was prime Tony himself scrawled "Speak to me" on the memo, dated 19 February 2003. Later that day, Mrs Blair spoke to Ms note to the cabinet secretary, dated 4 March 2003, says Mrs Blair agreed to speak to Paddy Campbell, Paul Smith and Nicole Farhi to "ask them to set out in writing their terms of trade, confirm that these terms are available to others (with personal shoppers or as individuals) and to provide an estimate of the numbers of people who bought their clothes in a similar way".She would also confirm that "confidentiality agreements" were in place with these intent was to "satisfy" Sir Andrew Turnbull, the cabinet secretary, that "no preferential treatment had been given".There is no mention of gifts of clothes discounts in the ministerial gift list in the file – which was published on 14 March behalf of the Blairs, the Tony Blair Institute said: " We have nothing to add to what has already been disclosed which shows that advice was sought and followed." As prime minister, Sir Tony received some extremely generous presents from famous people and world leaders.U2 lead singer Bono had given him a guitar – as had Bryan Berlusconi, the then Italian prime minister, offered multiple designer watches, including timepieces from Piaget, Corum, Jaeger-Coultre, and prime minister asked Ms Sumner to make the list "more boring" – so the published version did not include the type of watch, which can retail at many thousands of pounds wrote: "I have taken out details of individuals, removed the valuations for all items except those which have been purchased and minimised the descriptions of items."The concern over discounted clothes has similarities with criticism faced by Sir Keir Starmer and his wife. Last year he accepted more than £18,000 for spectacles and work clothing from the Labour peer Lord Alli, who also paid for some clothes for Sir Keir's wife Victoria worth just over £6,000.

The wealth tax options Reeves could take to ease her fiscal bind
Faced with a challenging set of numbers, the chancellor is having to make difficult choices with political consequences. Tax rises and spending cuts are a hard sell. Now, some in her party are calling for a different approach: target the wealthy. Is there a way out of all of this for the chancellor? Economic growth is disappointing and spending pressures are mounting. The government was already examining ways to raise revenue when, earlier this month, Labour backbenchers forced the government to abandon welfare cuts and reinstate winter fuel payments - blowing a £6bn hole in the budget. The numbers are not adding up for Rachel Reeves, who is steadfastly committed to her fiscal rules. Short of more spending cuts, her only option is to raise taxes - taxes that are already at a generational high. For some in her party - including Lord Kinnock, the former Labour leader, the solution is simple: introduce a new tax. They say a flat wealth tax, targeting those with assets above £10m, could raise £12bn for the public purse. Yet, the government is reportedly reluctant to pursue such a path. It is not convinced that wealth taxes will work. The evidence base is shaky and the debate over the efficacy of these types of taxes has divided the economics community. 1:16 Why are we talking about wealth? Wealth taxes are in the headlines but calls for this type of reform have been growing for some time. Proponents of the change point to shifts in our economy that will be obvious to most people living in Britain: work does not pay in the way it used to. At the same time wealth inequality has risen. The stock of wealth - that is the total value of everything owned - is much larger than our income, that is the total amount of money earned in a year. That disparity has been growing, especially during that era of low interest rates after 2008 that fuelled asset prices, while wages stagnated. It means the average worker will have to work for more years to buy assets, say a house, for example. Left-wing politicians and economists argue that instead of putting more pressure on workers - marginal income tax rates are as high as 70% for some workers - the government should instead target some of this accumulated wealth in order to balance the books. 2:19 The Inheritocracy At the heart of it all is a very straightforward argument about fairness. Few will argue that there aren't problems with the way our economy is functioning: that it is unfair that young people are struggling to buy homes and raise families. Proponents of a wealth tax say that it would not only raise revenue but create a fairer tax system. They argue that the wealth distortions are creating a divided society, where people's outcomes are determined by their inheritances. The gap is large. A typical 50-year old born to the poorest 20% of parents in the UK is already worth just a quarter of what someone born to the richest 20% of parents is worth at that age. This is before they inherit anything when their parents die. A lot of money is passed on earlier; for example, people may have had help buying their first home. That gap widens when the inheritance is passed on. This is when inheritance tax, one of the existing wealth taxes we have in the UK, kicks in. However, its impact in addressing that imbalance is negligible. Most people don't meet the threshold to pay it. The government could bring more people into the tax but it is already a deeply unpopular policy. 1:51 Alternatives So what other options could they explore? Lord Kinnock recently suggested a new tax on the stock of wealth - one to two percent on assets over £10m. That could raise between £12bn and £24bn. When making the case for the tax, Lord Kinnock told Sky News: "That kind of levy does two things. One is to secure resources, which is very important in revenues. "But the second thing it does is to say to the country, 'we are the government of equity'. This is a country which is very substantially fed up with the fact that whatever happens in the world, whatever happens in the UK, the same interests come out on top unscathed all the time while everybody else is paying more for getting services." However, there is a lot of scepticism about some of these numbers. Wealthier people tend to be more mobile and adept at arranging their tax affairs. Determining the value of their assets can be a challenge. In Downing Street, the fear is that they will simply leave, rendering the policy a failure. Policymakers are already fretting that a recent crackdown on non-doms will do the same. Critics point to countries where wealth taxes have been tried and repealed. Proponents say we should learn from their mistakes and design something better. Some say the government could start by improving existing taxes, such as capital gains tax - which people pay when they sell a second property or shares, for example. The Labour government has already raised capital gains tax rates but bringing them in line with income tax could raise £12bn. Then there is the potential for National Insurance contributions on investment income - such as rent from property or dividends. Estimates suggest that could bring in another £11bn. This is nothing to sniff at for a chancellor who needs to find tens of billions of pounds in order to balance her books. By the same token, she is operating on such fine margins that she can't afford to get the calculation wrong. There is no easy way out of this fiscal bind for Rachel Reeves. Whether wealth taxes are the solution or not, hers is a government that has promised reform and creative thinking. The tax system would be a good place to start.

The Modernization Imperative: Why Financial Services Cannot Afford Legacy System Inertia: By Sergiy Fitsak
The financial services sector has reached an inflection point where legacy system modernization has shifted from strategic advantage to business imperative. Institutions operating on decades-old infrastructure face mounting pressure from regulatory evolution, competitive disruption, and customer expectations that legacy architectures simply cannot meet. While modernization carries inherent risks in a heavily regulated environment, the cost of inaction has become demonstrably higher. Financial institutions that delay transformation risk regulatory non-compliance, competitive disadvantage, and operational inefficiencies that compound exponentially over time. The Convergence of Modernization Drivers Regulatory Complexity and Compliance Burden Modern financial regulations demand system agility that legacy platforms cannot deliver. Open banking mandates, real-time payment requirements, and evolving data privacy regulations require architectures built for adaptability, not just stability. Legacy systems with hardcoded logic and manual processes struggle to accommodate rapid regulatory changes while maintaining audit readiness. The compliance burden extends beyond implementation to documentation and reporting. Modern regulations require granular transaction tracking, real-time risk monitoring, and comprehensive audit trails—capabilities that legacy architectures often lack without significant workarounds. Competitive Pressure from Digital-Native Challengers Fintech startups and embedded finance providers built on cloud-native infrastructure consistently outpace traditional institutions in product innovation cycles. These challengers deploy new features weekly rather than quarterly, offer personalized services through advanced analytics, and provide seamless digital experiences that legacy systems cannot match without extensive customization. The threat extends beyond direct competition. Big Tech companies entering financial services with platform-based approaches force traditional institutions to reconsider their technology foundations to remain relevant in evolving ecosystems. Evolving Customer Expectations Digital-first customers expect instant account opening, real-time payment processing, and personalized financial insights. Legacy systems designed for back-office efficiency rather than customer experience struggle to deliver these capabilities without introducing significant latency or operational complexity. The gap between customer expectations and legacy system capabilities continues widening as digital experiences in other sectors set new standards for responsiveness and personalization. Strategic Modernization Approaches for Financial Services Incremental Architecture Evolution Financial institutions typically cannot afford the operational risk of wholesale system replacement. Successful modernization strategies focus on incremental transformation that preserves business continuity while enabling progressive capability enhancement. Core system wrapping with API layers represents the most common initial approach. This strategy enables modern applications and partner integrations to interface with existing systems without requiring core logic changes. The approach provides immediate value while establishing the foundation for more comprehensive modernization efforts. Cloud-First Infrastructure Strategy Hybrid cloud adoption allows financial institutions to balance regulatory requirements with operational efficiency. Non-critical workloads such as analytics, customer portals, and development environments migrate first, while sensitive transaction processing remains in controlled environments until regulatory frameworks evolve. Cloud-native services enable advanced capabilities—real-time fraud detection, predictive analytics, and automated compliance monitoring—that would require significant investment to develop internally on legacy infrastructure. Data Architecture Modernization Modern financial services require real-time data processing for fraud prevention, regulatory reporting, and customer personalization. Legacy ETL processes and batch-oriented data flows cannot support the analytical requirements of contemporary financial products. Event-driven architectures using modern streaming platforms enable real-time transaction monitoring, instant fraud detection, and immediate regulatory reporting while reducing system complexity compared to traditional batch processing approaches. Implementation Considerations and Risk Mitigation Regulatory Compliance in Modernized Environments Modernization efforts must maintain regulatory compliance throughout transformation phases. This requires careful planning around data residency, audit logging, access controls, and disaster recovery capabilities. Modern architectures actually enhance compliance capabilities through improved observability, automated monitoring, and granular access controls. Documentation and change management become critical during modernization to satisfy regulatory requirements for system understanding and control procedures. Operational Risk Management Financial institutions require comprehensive testing strategies that validate not just functionality but also performance under stress conditions. Modern infrastructure enables more sophisticated testing approaches including chaos engineering and automated load testing that improve system resilience. Rollback capabilities and feature flagging ensure that modernization efforts can be reversed quickly if issues emerge, reducing the operational risk of transformation initiatives. Skills Development and Team Alignment Successful modernization requires workforce development alongside technology transformation. Teams accustomed to legacy systems need training in cloud-native development, API design, and modern DevOps practices. Organizations often supplement internal teams with specialized expertise during transition periods to accelerate knowledge transfer and reduce implementation risks. Measurable Business Impact Operational Efficiency Gains Modernized financial institutions typically achieve significant cost reductions through automated processes, reduced manual interventions, and improved system reliability. Cloud-native infrastructure provides variable cost structures that align technology spending with business growth rather than fixed capacity planning. Enhanced Customer Experience Modern architectures enable real-time personalization, instant transaction processing, and seamless omnichannel experiences that drive customer satisfaction and retention. The ability to launch new products rapidly allows institutions to respond quickly to market opportunities. Regulatory Responsiveness Modern systems adapt to regulatory changes more efficiently through configuration rather than code changes. Automated compliance monitoring and reporting reduce manual effort while improving accuracy and auditability. The Path Forward Financial services modernization represents a strategic imperative that cannot be indefinitely deferred. Institutions that approach transformation systematically—balancing innovation with risk management—position themselves for sustainable competitive advantage in an increasingly digital financial ecosystem. The question facing financial leaders is not whether to modernize, but how to execute transformation that enables growth while preserving institutional stability and regulatory compliance.
