u/Alert-One-Two

Husband is a contract software developer and works from home via our Ltd. He uses our spare bedroom as an office space. It is getting very hot and whilst we have portable air conditioners in all the other bedrooms we don’t have one in there because no one sleeps in there (you can as there is a bed, but we never have a need). Would it be reasonable to purchase a portable air conditioner via our business given it would solely be used during his work hours to ensure the room is cool enough for him to focus? Or because the room also doubles as a spare bedroom would that make it harder to justify?
