If you don't choose to work from home (e.g. you're forced to), and your employer doesn't give you any extra towards doing so, then you should be able to claim £6/week tax relief without having to provide any proof/receipts:-

Given that's [tax relief on] £312/year (that's meant to cover the increase in utility bills, etc from being at home all the time). I've worked from home two days a week for the last 10 years but that was by choice so that doesn't qualify. However Coronaplague has meant I've been forced to work from home since March, so I've definitely got a chunk of tax I can claim back come next tax return and I plan on sticking that towards home office upgrades.
(I've wibbled about upgrading my home setup before. Ideally I'd like to try a single 43" 4K monitor to replace the two existing 23" 1920x1080 monitors, but the £430 4K monitor that was on Scan has gone and the cheapest is now £530. An alternative would be two 27" 2560x1440 monitors mounted vertically giving 2880x2560 but that's still £470 at the cheapest with VESA mounts.)
This was the main reason for the stand and separate screens. I've had the laptop and a separate keyboard, with the laptop up on a riser, but it's just too small a screen for any hardcore excel funky timez.
Next step is to find someone in IT who I can bully to switch the 24" for a matching 27", but that will need to wait until the new house, as I have no more lateral real estate with a wall to my left and the IKEA kallax to my right.
