I found Knauf Rockwool from Wickes was easily cuttable with a box cuttter, or wallpaper scissors were good. FWIW I lifted and cleared all the left over rubble from our in situ insulation, installed wooden flooring with loft legs, removed the old board and layed new insulation on top of the old in probably 2 full working days. I did that over a couple of weeks doing an hour or so most nights, then a few few hour stints in weekends. Get a decent mask, white coverall, gloves and goggles (wear contact lenses if you need glasses)and I found it ok. Don’t worry about overlaps as it’s just extra insulation.
Sounds like you should get yours done in a day no problem.
It doesn’t take long to lift the wire up and tuck the insulation under.
Unless you are lucky enough to have conduit.
Use an old saw to cut it to width while it’s in the wrapper.
Wait. Wut? God dammit!
I also used the recycled plastic bottles. It is a joy to use, no itching.
The recycled plastic stuff from B&Q I’ve found to be expensive compared to recycled glass, and difficult to cut and tear (easier than cutting) than Rockwool

All qualities which make it great for retrofitting into the 175mm gap in the sloped bits of my roof.
So far only been able to get my hands on one roll though. Been out of stock consistantly since.
“how hard can it be?” the good lady however is telling me it’ll take me a week (I’d say a day at the absolute most)
Don't tell her that whatever you do! Imagine the consequences 😉
Im doing ours at the moment, also doing between joist shelves and changing the landing lights while I'm at it- using that Knauf stuff from Wickes, pretty affordable and tbh you dont need any PPE on at all.
Treated myself to a GVS pp3 mask for when it gets dusty, much better than the disposable paper ones
