Monzo Races Past 14 Million Customers Amid Record Growth and Standout Engagement

Monzo has raced past 14 million customers, after a record 2 million individuals and businesses joined the UK’s largest digital bank in the six months to September 2025 – around a 40% uplift year-on-year.

Monzo is fast-becoming the bank of choice for small businesses, having just topped 800,000 business customers – equivalent to one in seven SMEs across the UK. Customer sign-ups surged in the first half by around 50% year-on-year, as more customers turned to Monzo’s intuitive tools to save time and simplify their finances. To make running a business even easier, Monzo will soon launch a new tax filing tool that lets sole traders and landlords submit their taxes directly to HMRC from their Business bank account.

High customer satisfaction continues to underpin Monzo’s incredible growth, with the bank this week named a Which? Recommended Provider for Current Accounts for the second year running. Monzo achieved a score of 85% with customers calling out features such as fee-free international spending, bill-splitting, interest-paying savings pots, and budgeting tools in particular.

Alongside the rapid growth in new customers, existing customers are also using Monzo more than ever with around 70% of customers active every month. Meanwhile, over 1 million personal customers now subscribe to Monzo’s paid plans, deepening their engagement through enhanced budgeting tools, better savings rates and exclusive partner benefits such as weekly Greggs treats and monthly Vue cinema tickets.

With products that span every life stage – from learning to budget and save with an Under 16s account to managing a Monzo Pension in later life – customers are increasingly bringing more of their financial lives to Monzo. This latest customer milestone follows the launch of a series of new products and features in the past six months including:

• Interest-earning savings accounts for Under 16s – 3% (variable) interest on Under 16s Savings Accounts, helping the next generation grow their money faster.

• Home Insurance – a combined buildings and contents policy that allows homeowners to personalise their cover and change or cancel their policy at any time with no extra fees.

• ETFs – 11 carefully curated Exchange Traded Funds, designed for customers who want more choice in their investing while keeping it simple and accessible for first-time investors.

• Undo Payments – another industry-first security feature, which gives customers a customisable 10-60-second window to cancel a bank transfer if a mistake is made.

Andy Smart, Chief Product Officer of Monzo, said: “When you build a bank that people love, growth follows. More and more people and businesses are choosing Monzo, they’re using it more often, and they’re trusting us with more of their financial lives. Customers tell us that we’re transforming their relationship with money, building deep engagement and trust that turns new customer sign-ups into long-term relationships. That is what really powers our success.”
