The majority of people prefer to contact insurers by phone, says research from Standard Life Healthcare.
The survey of 1,021 adults found that 59% prefer to use the phone, followed by the web (18%), the post (15%) and email (8%).
Internet security is now trusted by 28% of adults, but this is still less than the post (42%) and phone (68%).
When it comes to claiming on insurance, four in ten people would claim through a website for health insurance.
The survey also found that just three in 10 people who buy something over the web read the terms and conditions before accepting them. Of these, more than one in two said this is because they trust the brand.
