A Professional Comparison of Monzo, Starling, Revolut and Chase
TL;DR Summary: The best banking apps in the UK are Monzo for budgeting-focused consumers, Starling for those wanting a complete bank replacement with excellent customer service and global ATM access, Revolut for multi-currency management and international spending, and Chase UK for cashback and high-yield savings. All four are now fully regulated UK banks with FSCS deposit protection up to £85,000. The best choice depends on your daily banking habits, international usage, and whether you prioritise budgeting tools, fee-free global spending, or cash rewards.
The UK Digital Banking Market in 2025
The United Kingdom has become one of the most competitive and mature digital banking markets globally, with app-based challenger banks collectively serving tens of millions of customers across personal and business accounts. Monzo serves over 12 million UK customers. Revolut has grown to more than 65 million customers worldwide, including approximately 10 million in the UK. Starling Bank, which achieved B Corp certification and reached profitability, saw a 20% increase in new account openings in 2024. Chase UK, operated by JPMorgan Chase and launched in the UK in 2021, has attracted significant adoption through its cashback and savings interest proposition.
A pivotal regulatory development in 2025 was Revolut's receipt of a full UK banking licence, bringing it under the Prudential Regulation Authority's supervisory framework and extending FSCS deposit protection to UK customers. This means that all four of the platforms discussed in this guide now operate as fully licensed UK banks with equivalent deposit protection to legacy high-street institutions such as Barclays, HSBC, and NatWest. The practical consequence for consumers is that the risk differential between digital and traditional banks has been materially reduced, and the comparison between them now centres almost entirely on features, pricing, and customer experience rather than safety.
Monzo: Best for Budgeting and Everyday Spending Management
Monzo was founded in 2015 and built its reputation on a spending insights and budgeting interface that set the benchmark for transparency in retail banking. The app provides real-time transaction notifications, automatic spending categorisation, the ability to create named savings Pots that can be set to lock until a target date, and an early salary access feature for qualifying customers. Shared tabs for splitting bills and a round-up feature that transfers spare change from purchases into a designated Pot make the platform particularly well suited to consumers who want to actively manage their money rather than passively monitor it.
Monzo's standard current account is free with no monthly fee. Paid subscription tiers, including Extra, Perks, and Max, are priced from £3 to £17 per month and unlock additional features including travel insurance, higher ATM withdrawal allowances abroad, and cashback at selected retailers. The current account pays interest on balances through linked Cash ISA and savings accounts managed within the app. Monzo also provides a personal loan product and an overdraft facility, positioning it as a more complete financial platform than many of its digital competitors. Its app consistently receives high usability ratings from both customer surveys and independent technology reviews, and its large community of active users creates a network effect that contributes to social features like bill splitting and shared pots.
Starling Bank: Best Overall Digital Banking App
Starling Bank is consistently rated by independent consumer bodies including Which? as a recommended banking provider, and its app has topped user satisfaction surveys across multiple years. The bank was founded in 2014 and achieved full-year profitability before most of its digital banking peers. Its standard personal current account carries no monthly fee, earns interest of approximately 3.25% AER on positive balances up to £5,000, and provides unlimited fee-free ATM withdrawals and card spending globally, with the Mastercard exchange rate applied to international transactions.
Starling's customer service model differentiates it from most digital competitors: the bank offers telephone support, making it one of the few app-based banks where customers can speak to a human agent when needed. The app provides spending categorisation, a Spaces feature equivalent to Monzo's Pots, cheque deposit via in-app scanning, and free cash deposits at Post Office locations. For business users, Starling offers a fully featured business current account at no monthly fee, with optional paid business toolkits for invoicing and accounting integrations. The combination of no-fee everyday banking, global card and ATM access, telephone customer service, and a profitable, independently operated business model makes Starling the strongest single-product digital bank for most UK consumers seeking a primary account replacement.
Revolut: Best for International Spending and Multi-Currency Accounts
Revolut's core competitive advantage lies in its multi-currency architecture and international financial functionality, which remains materially superior to any competing app-based banking product in the UK market. The platform allows customers to hold more than 30 currencies simultaneously, exchange between them at interbank rates up to monthly limits that vary by plan, and send money internationally to over 160 countries with competitive fees and fast processing times. Weekend exchange transactions incur a 1% markup over weekday interbank rates, a pricing characteristic that regular users should factor into their currency management habits.
The standard Revolut plan is free and provides access to the core multi-currency features, with foreign exchange fee-free up to £1,000 per month and fee-free ATM withdrawals up to £200 per month worldwide. Premium and Metal paid tiers, priced between £3.99 and £55 per month, extend these limits, add overseas medical insurance, provide discounted airport lounge access, and unlock cashback and investment features. Revolut also offers cryptocurrency and stock trading through its app, though these carry significant market risk and operate under different regulatory protections than the banking and payments functions. For frequent international travellers, digital nomads, freelancers paid in foreign currencies, and professionals managing multi-currency cash flows, Revolut's feature set is unmatched by any other consumer banking app in the UK.
Chase UK: Best for Cashback and Round-Up Savings
Chase UK, launched by JPMorgan Chase in the UK market in 2021, occupies a distinct position in the digital banking landscape by emphasising cash rewards and savings interest rather than budgeting tools or multi-currency features. The account offers 1% cashback on eligible card spending, making it one of the few UK current accounts with a genuine, sustained cash reward on everyday purchases. A round-up savings account earns 5% AER on balances built from transaction round-ups, providing a compelling savings incentive for customers who want to build savings passively through daily spending patterns.
The standard Chase UK current account earns 3.35% AER on current account balances, rising to 3.85% AER for customers on paid account tiers. The app is well-reviewed for design and usability, with Monzo and Revolut cited in some comparative assessments as stronger for app design while Chase is positioned for customers motivated primarily by the financial rewards structure. FSCS protection for Chase UK deposits is shared with JPMorgan Chase, which requires customers to account for any existing JPMorgan deposits when calculating their protected balance. Chase UK does not currently offer business accounts, personal loans from a dedicated product, or the extensive budgeting tools available on Monzo and Starling, positioning it primarily as a rewarding everyday spending account rather than a comprehensive banking platform.
Security and FSCS Protection Across All Four Apps
All four platforms discussed in this guide are authorised and regulated by the Financial Conduct Authority and Prudential Regulation Authority and provide FSCS deposit protection up to £85,000 per person per institution. This is the same level of protection provided by all major UK high-street banks. Standard security features across all four apps include end-to-end encrypted data transmission, two-factor authentication for account access and payment approval, biometric login via fingerprint or facial recognition, and the ability to instantly freeze and unfreeze the debit card from within the app. All four also deploy transaction monitoring systems that flag and in some cases block suspicious activity in real time.
Customers who hold balances approaching the £85,000 FSCS protection threshold across multiple institutions should distribute funds accordingly, as the protection limit is applied per institution rather than per account. The Chase UK FSCS limit is shared with JPMorgan Chase, meaning customers with existing JPMorgan products should calculate their total combined exposure when assessing protection coverage.
International Spending and ATM Fee Comparison
For international spending and ATM access, the four apps offer materially different propositions. Starling charges nothing for card spending or ATM withdrawals anywhere in the world on its standard free account, applying the Mastercard exchange rate to all foreign currency transactions. Monzo charges nothing for card spending abroad but imposes ATM withdrawal limits of £200 per 30-day period outside the UK and EEA for customers not using Monzo as a primary account, with a 3% fee above the threshold. Revolut provides interbank-rate currency exchange up to £1,000 per month for free on its standard plan, with a 0.5% fee above this limit, and fee-free ATM withdrawals up to £200 per month with a 2% fee thereafter. Chase UK applies Mastercard exchange rates to international spending without a foreign transaction fee, though international ATM policy should be verified directly with Chase for the most current terms.
Business Banking Capabilities
Starling Bank offers the strongest business banking proposition among the four apps, providing a fully featured free business current account for sole traders and limited companies with no monthly fee, integrated accounting connections, and multi-currency accounts in GBP, EUR, and USD. Monzo offers a business account with a free Lite tier and a Pro tier at £9 per month, the latter including invoicing and accounting integrations. Revolut Business provides business accounts starting at £10 per month, with stronger multi-currency and international payments capabilities than either Starling or Monzo for business use cases involving regular cross-border transactions. Chase UK does not currently offer a business account.
How Digital App Banks Compare to Traditional Banks
The competitive gap between digital app banks and traditional high-street institutions has narrowed significantly in the years since 2015. All major UK banks now offer mobile banking applications, and several, including First Direct and Nationwide, receive high customer satisfaction ratings for their digital offerings. MoneySavingExpert's consumer poll found that Starling and Monzo topped ratings for app usability and features among all UK banks, digital and traditional alike, with RBS noted as the highest-rated app among traditional institutions at 73% positive usability ratings. The primary areas where traditional banks retain a structural advantage are physical branch access for complex transactions, a broader range of mortgage and investment products, established credit history reporting relationships, and longer operating track records that provide greater institutional confidence for some consumer segments.
Frequently Asked Questions
Which is the best UK banking app for everyday use in 2025?
Starling Bank is widely considered the best all-round digital banking app for everyday use in the UK, offering a free current account, interest on positive balances, global fee-free card and ATM use, telephone customer service, and strong app usability ratings. Monzo is the top choice for users who prioritise budgeting tools and spending management features. The best option depends on whether your primary requirement is global spending flexibility, budgeting functionality, or cash rewards.
Is my money safe in Monzo, Starling, Revolut, or Chase?
Yes. All four are fully authorised UK banks regulated by the FCA and PRA, with customer deposits protected by the Financial Services Compensation Scheme up to £85,000 per person per institution. This is the same protection level as traditional banks including Barclays, Lloyds, and NatWest. Revolut's UK deposits have been FSCS protected since 2025 following its full UK banking licence.
Does Starling Bank charge for spending abroad?
Starling Bank charges nothing for card spending or ATM cash withdrawals anywhere in the world on its standard free personal account. The Mastercard exchange rate, which closely tracks the mid-market rate, is applied to all foreign currency transactions. There are no additional foreign transaction fees, ATM withdrawal fees, or monthly charges for this feature on the standard account.
What is the difference between Monzo and Starling for business banking?
Starling offers a free business current account with most core features included at no cost, making it the stronger value proposition for most UK small businesses and sole traders. Monzo's free business Lite tier is more limited, requiring an upgrade to the £9 per month Pro tier to access invoicing and accounting integrations. Starling also offers multi-currency business accounts in GBP, EUR, and USD, which Monzo does not. For international business banking, Revolut Business provides a more comprehensive multi-currency and FX feature set.
Should I use a digital bank or a traditional bank as my main UK account?
For most consumers whose primary banking needs involve everyday spending, savings, and domestic transfers, digital banks such as Monzo, Starling, or Chase UK offer equivalent regulatory protection to traditional banks at lower or zero monthly cost, with superior app functionality and in many cases better terms on international spending. Where traditional banks retain a meaningful advantage is in in-person branch services, a broader product range including mortgages and wealth management, and longer operating track records. Many UK consumers maintain accounts with both a digital challenger and a traditional institution to access the best of each.
