Initial trials
The Plain Numbers version sought to communicate the same information in a way that was clearer and easier to understand.
We asked 5 comprehension questions to really prove whether customers understood the communication. We considered someone being able to answer 4 of these questions correctly an example of good understanding.
In this trial questions to participants included:
'What is the cost to transfer your debt to Card B?' and 'If you can only afford to pay £75 a month to pay off your debt, which card is best for you?
