As digital payments continue to grow in popularity, the UK is experiencing a significant shift towards cashless transactions. With the rise in contactless payments and digital wallets, we’re witnessing how everyday consumers are relying less on cash and traditional payment methods.To discover how payment preferences are evolving, SumUp conducted a nationwide survey, gathering insights from UK consumers about their payment habits. The findings offer valuable insights for SMEs, helping them to better understand shifting purchasing behaviours. Insights include the payment methods people prefer, their concerns around certain payment methods, alongside how they feel about businesses that don’t accept digital payments.What are UK consumers’ preferred payment methods?In recent years, the way people pay for goods and services has gone through a significant transformation. With a growing range of payment options available, from contactless cards to mobile wallets, and Buy Now, Pay Later services, consumers are increasingly looking for convenience, security, and flexibility in how they make purchases. But which methods are the most preferred?Over half of people (62%) say that they prefer to pay with debit or credit cards, highlighting the continued dominance of traditional card-based transactions.In addition, 18% of consumers find mobile payment options, such as Apple Pay and Google Pay to be the most convenient choice, reflecting the growing adoption of digital wallets
As digital technology continues to reshape the financial landscape, banking preferences are shifting in significant ways. Traditional bank branches, once the cornerstone of personal finance, are becoming less central to people’s banking needs.To explore how preferences are changing when it comes to their banking habits, SumUp conducted a nationwide survey, gathering insights from UK consumers about banking. The findings offer valuable insights into whether people would consider switching to a fully digital, branchless bank, how often they visit their bank branches, and the changes they have noticed in services offered.Would Brits consider switching to a fully digital, branchless bank?Whilst the survey suggests that overall, 66% of Brits are open to switching to a fully digital banking experience (18% have already switched, 23% are open to switching and see the advantages, while 25% would consider it with more information), attitudes towards the shift to digital banking vary notably by age group.Among 18 to 24-year-olds, 29% have already embraced a fully digital banking experience, with an additional 29% open to making the switch – attracted by its convenience and benefits that come with it. A further 25% in this age group said they would consider transitioning after receiving more information about the pros and cons.The trend continues among those aged between 25 and 34, with 27% already using digital-only banks and over a third (36%) seriously considering the move. For younger generations, the appeal of fast and flexible banking options is clear, reflecting their preference for convenience and tech-driven solutions.Interest remains strong in the 35 to 44 age bracket, where 22% have already made the switch, 30% are considering it based on perceived advantages, and 29% would be open to it with a better understanding of the benefits.As expected, interest in fully digital banking declines with age. Among those aged 45 to 54, just 14% have made the switch to a branchless banking experience, a figure which remains consistent in the 55 to 64 age group
