Digital banking statistics 2021

Over a quarter of Brits (14 million) have opened a digital-only bank.

Digital banks (such as Monzo, Revolut and Starling Bank) offer simple, fee-free services for people wanting to track their spending immediately from their digital device. Our data shows that people really value good digital services from their bank, which helps explain the consistent increase in online banking use over the last 10 years. We looked for the latest stats on digital banking in the UK, along with carrying out our own research on how people are using their accounts and their future intentions when it comes to banking. Some digital banks have even been recommended in a list of the best banks in the UK.

According to our survey:

  • Over a quarter (27%) of British adults have opened an account with a digital-only bank, equating to 14 million people (2021).
  • This means 3 times more Brits have a digital bank than in January 2019 (9%).
  • By the end 2021, 38% of Brits either will have or intend to have a digital only bank – equal to almost 20 million Brits.
  • 4 in 5 (80%) use some form of online banking in the UK.
  • Just over 1 in 10 Brits (12%) have fully switched to a digital-only bank.
  • Nearly half (47%) of those who use them keep less than £1,000 in a digital bank, in 2019.
  • Two-thirds of banking customers say they plan to convert fully to a digital bank in the future.

High street vs Digital Banking: which banks are winning customers?

Looking at 2020’s third quarter (1 July – 30 September), Starling Bank and Monzo made net gains of 12,652 and 9,157 customers respectively, while Barclays, HSBC, NatWest and Santander all made net losses.

Halifax had the highest overall increase in customers, with a net gain of 22,742 customers. However, Halifax was offering a switch deal during this period and was the only high-street bank to make considerable gains.

The data shows a 65% drop in total switches during lockdown vs the first three months of 2020, which reflects a decline in the number of switching incentives while banks seemed to focus on their existing customers.

High street vs Digital Banking: consumer opinions over the COVID-19 pandemic

Customer sentiment towards 10 of the UK’s biggest high-street and digital-only banks fell by 7 percentage points (pp) during lockdown, according to our new research from and social analytics specialist BrandsEye.

This leaves overall consumer sentiment for the banking industry at -24% on a possible scale of +100% to -100% for the period between 1 March and 31 July.

However, over 800,000 social media posts from customers revealed that digital banks saw a sentiment decline of almost three times that of high-street banks during the pandemic. On average digital-only banks’ customer sentiment fell by 14pp compared to just 5pp for high-street banks.

While this is a blow for digital-only banks, it should be noted that high-street banks had, and continue to have, a much lower overall sentiment (-13% vs -35% currently).

Sentiment pre-lockdown Sentiment post-lockdown Percentage point difference
Atom 11.2% 9.2% 2.00%
Starling 12.4% -1.4% -13.80%
