Employers have been warned they could be exposed to legal claims if they fail to ensure that staff working from home have a safe environment.
Insurance Ireland said there is a danger that remote working could become too expensive due to the risk of "frivolous claims".
Under health and safety legislation, employers must ensure a safe workplace for their staff, including those working from home.
If adequate precautions have not been taken to ensure safety, it could trigger costly claims for anything from bad backs, to slips and falls, to data breaches.
