The site was speaking after a new report suggested councils should introduce loneliness maps to find the most vulnerable people in society and target them with relevant services.
The report, by charity Hidden Citizens, said local services should use their data to find the most isolated residents, such as people over 65, those without a car or people that live alone.
David Pullinger, the Director of Single Christians Limited, said loneliness can have the equivalent effect of smoking 15 cigarettes a day on someone's health. He also said councils must target older people because they tend to be less mobile and have less social connections.
He told Premier: "Some things suit some people, some things suit other people. For example going to groups definitely suits people more extrovert than introvert and introverts just won't want to do that - so if the council... set up groups for older people, only certain sorts of people would go to those.
"So we have to have a range of different interventions to support people: one-to-one communication is much better for introverts for example, and they naturally choose to be more isolated because they're happy with their own company. But they also need social connections - so that's home visits as opposed to groups."
Who can you call at 1am in the morning, who can you rely on when you go into hospital to really help you, what sort of person might that be?", he added.
"When I ask this question people have very low levels of friendship compared to what I had when I was young.
"I just feel that we want to encourage everyone into this role of friendship."
