Money touches every part of our lives. We use it to do day-to-day things, like to get from A to B. And at major milestones, like buying a house or moving abroad.

However, instead of thinking about how money fits into the way we live, and how it can help us achieve our goals and ambitions, the big banks have built their business models around selling financial products. After attracting people with loss-making introductory offers, they make money by cross-selling higher-profit products like mortgages, loans and credit cards.

It’s difficult to decipher the difference between these almost-identical products, so we tend to choose our banks for relatively arbitrary reasons, then stay with them forever, allowing them to fulfil all our financial needs. According to Wired UK, since 2013 only 5% of an estimated 70 million account holders in the UK have ever changed their bank.
