On average, people stay with their bank for 17 years—which implies that it’s either too much effort to switch, or that they have brand loyalty beyond belief. People are more likely to stay with their bank than they are to stay with their partner.
A study from 2020 estimated that within 5 years 44% of brits will have a digital-only bank. But most of you reading this will already have an account with at least one of the challenger banks, like Monzo, Revolut or Starling. You probably also remember the experience being far better than when you set up your traditional bank account more than a decade ago.
But was the application process actually any better, or are you just wrongly assuming that your traditional bank hasn’t improved since 1995?
This chapter sets out to answer the question: is it actually any easier to open an account with one of the challenger banks, or it is all a brilliantly orchestrated marketing spin.
Summary: The challenger banks were significantly quicker (in days) and required less effort (in clicks) to get an active account.
📱
Allowed you to open an account directly through the app.
⚡️
Changed the perspective of when your account is ‘open’.
🌋
Remove the worst part of the traditional experience.
🗂
Minimised data collection.

Created a memorable experience when your card arrives.
The industry can be confusing. Promises of “opening an account in minutes” are enticing, and might technically be true, but don’t reflect what we really experience.
In the real world, you’d probably only say your account was active when you could actually use your card. So I set the following parameters:
1. I can use my card in a shop. This includes receiving my PIN.
2. I have access to online banking on my mobile. This includes receiving my card reader (if needed).
And remember, none of the banks knew they were in this race.
As you’d expect, the challenger banks were considerably faster than the more traditional banks. And remember; these are working days, not calendar days.
But when we talk about how easy something is, there’s another metric to consider: effort required. Typically, products feel more intuitive—and easier—the less input they need. So I also logged every time I had to do something.

A behind the scenes look at how I redesigned the Built for Mars sign-up flow, and iterated from early feedback.

Sometimes, the best onboarding is no onboarding, and simple products get bogged down with unnecessary explanations. This case study on Waitrose, Sainsbury's and Asda demonstrates when to just let the user try it for themselves.
Sometimes the best onboarding, is no onboarding
“Show, don’t tell” often beats education
Data can’t always tell you when onboarding is wrong
