He added that reading the small print could have consequences when buying products like critical illness cover and private medical insurance.
"People tend to look at the top line and not the small print and, if you take critical illness cover as an example, some critical illness cover will have lesser benefits than others, but obviously the premiums are also lesser," he explained.
"It's the same with private medical insurance; the excess isn't whether it's on in-patients or out-patients cover; this will produce lower premiums."
