The flexible workspace provider analysed figures from the Office for National Statistics on office location and home working, predicting that 1.6 million people could be at risk from loneliness by 2025.
Self-employed workers unsurprisingly make up the bulk of those who work from home for all or most of the week, and 30% of these workers report feeling lonely either often or always.
Because the proportion of self-employed workers will rise to more than 15% of the working population next year, or 5 million people, this means many more workers will be missing out on social interaction.
Only 14% of employees work from home full time with no office days at all, it found.
