A number of ads on property letting sites are warning potential tenants they aren't permitted to work from home.
Several posts say that remote workers will not be considered for a room, with one post in particular saying the practice "won't suit the atmosphere" of the property.
Other reasons include higher electricity costs and a lack of space.
CEO of Online-applications-dot-com, Karl Deeter, believes live-in landlords may have valid reasons for not welcoming remote workers:
"You could have a situation when someone is a therapist, and they're dealing with people who have very profound problems, and they operate their practice from home. And someone else might be working in sales. It would be inappropriate to have them talking loudly on a zoom call in the next room".
Landlords who allow tenants to work from home should update their house insurance policy, according to an employment law solicitor.
Solicitor Richard Grogan says landlords could face a personal injury claim if a tenant gets injured while working from home:
"People are saying I'm working from home, what's the problem? But if somebody has an accident or somebody's injured-then the insurance company says you're not insured for this".
The house rule has raised some eyebrows online, though the vast majority of listings don't appear to have an issue with remote workers moving in.
