The large increase in remote work since 2020 has prompted concerns about adverse effects on population loneliness and mental health. We show that any such adverse effects were transitory, in a UK context. We use panel data from UKHLS and differences-in-differences estimators that flexibly control for a rich set of covariates to compare changes in key variables amongst two groups: those who worked in teleworkable occupations in 2019, and those who worked in non-teleworkable occupations in 2019. While the former experience large and persistent increases in their probability of working remotely compared to the latter, adverse relative changes in self-reported loneliness or adverse mental health symptoms during the pandemic had disappeared by the year 2023.
