As part of my company's working from home assistance, we can expense for "increased utility costs" due to WFH. This is not something I'd bothered with before - the increase in the amount I was paying seemed negligible, maybe due to year-to-year variability or an increase in how much they charge. But that changed when I got my electricity bill today, which was shockingly high. The cost of keeping my house heated all day has seemingly made a big difference - something I would obviously not notice during those warmer months. So, after consulting my manager about my intentions, I have submitted an expense report today for the difference between what I've been paying since starting WFH (9 month ago! - good grief) and the equivalent months from last year (which added up to not an insignificant amount). It will be very interesting to see if these expenses get approved...
