Heat the space immediately around you. Don't bother with central heating. Get a small electric blanket that you can have on your lap.

If you are feeling more adventurous I got through a cold winter where the heating broke when I was a student with a mix of warm clothing, blankets, and doing exercises to keep warm. When you start getting cold, do some press-ups/squats etc.

If you are feeling really adventurous I would recommend going outside wearing less clothes than you want to, just trousers and a shirt/jumper. When you get really cold head back in and it will seem positively warm! Another way of doing this is cold showers.

I'd say heat the person, not the space. Following on from the Electric Blanket mention, I'd recommend a heated vest. I have one made by Arris [1], and it has a 7.4V battery. Following a tip in an Amazon review, I contacted their customer services and got a voucher for a second battery at half price.

Last winter, I used it a lot when WFH to avoid the temptation of using the boost on the central heating. With two batteries, one can be charging while the other is in use. According to my meter plug it was economical to charge.

I found it worked best with a thin base layer underneath the heated vest, and a good fleece over it. There are several heating areas on the front and back, and I found that the battery lasted best by starting at the highest heat setting and then stepping down through the levels as I warmed up. Very useful when sitting still long periods at your computer. And of course the advantage over a blanket or electric fan is that you can walk around with it on.

I agree, but OP seemed a bit reluctant to try that so I suggested the next best thing.

Thanks for the heated vest suggestion.
