Close the lock shield valve (folks say to count the number of turns it takes to close it so you can open it the same number when reinstalling to help balance the system - I have never done this and all my rads still work but I could be lucky). What is on the other side? If a normal dumb valve, just close it also. If a TRV, then shut that off and if not knackered, it will be fine. I don't trust them by themselves so I tend to put blanking nuts on too if a rad is going to be off for an extended period of time for fear of something failing in the night and pissing shitty heating system water everywhere.
I hate reinstalling old/used rads as I am SHIT at plumbing so I generally end up buying new rads and getting a plumber to fit new valves. But then, all the ones I've taken off here have needed to be replaced anyway.

Isolate both the oncoming and outgoing. Make sure to cap off any thermostatic valves properly so they can't turn on and cause 40 grand worth of damage to your house. Do not trust turning a trv to cold/off.
Seal the plumbing once removed to stop crap like plaster getting in the pipes. This could be proper end caps or tin foil and masking tape.
If you can, flush the rad while it's off.

If you have loads more DIY coming get a titan vac that does water as well as dust.
Great for sucking out the dirty water and cleaning up any spills.
Probably the most used thing of my DIY journey

Right... So I've got a plasterer coming tomorrow who has said their happy to help remove a fuck off big wall mounted radiator prior to starting work.
What do I need to do?
Just turn off the rad and drain? Then we disconnect it and lift it off and put it somewhere, right?
Or am I missing something?
Any "oh I wish I'd know this" tips?
Cheers.
