Sorry I know its the good news thread.
I have WFH for 15 years, a couple of points.
Make sure you home insurance company are OK with this.They may want a few quid more.
Your company should be paying for BT business broadband or similar as your be using for work more than pleasure.
Try and have a home office, it gets gutting working off the kitchen/ dinning room table.
Try and get them to pay a homeworkers allowance as in the winter your fuel bills will rocket + your laptop, printer, all take power as well as kettle ,tea and milk all cost you money. ( sounds tight I know but save the pennies and all that)
Working from home is great not just for you but the company can also save them quite a bit.
Good points..............but I was already saving maybe £2kpa on not commuting to London before Covid by WFH some of the time, I spend way, way less on coffees, breakfast, lunches etc and socialising by being at home and don't need to spend anything like as much on business attire. My broadband cost would be the same whether I was working or not, and there are no additional telephone costs (all work calls are via internet/softphone). Mrs D doesn't work so fuel bills haven't changed as she's at home anyway.
Def agree re an office if you can and have the space - I'm lucky that we have one (I've WFH at least part of the time for 20+ years now). I set it up a few years ago now with a proper corner desk, decent monitors, good quality adjustable office chair etc etc. It's way better than what I get to use in our actual office, and I can sit there in my pants whilst speaking to the Group Compliance Head
