That's nowhere near as straight forward as you think it is, few hundred quid including one that has a freezing machine. No chance, if there is one bit of water running in that system the pipes won't free!
Id personally get the landlord to do it and take nothing to do with it if you really dont know what your doing.
You could do it live but even that is fucking risky!

As for doing it myself, I was gonna do that with proper kit rated for up to 42mm pipe not a single use sleeve. And I wouldnt attempt installing a shutoff valve mid-line, just changing the one on the radiator with the line frozen. I'd also have tools ready to crimp the pipe in a worst case scenario.
I have soldered copper pipes before, I have flushed radiator systems, changed thermostatic valves...etc, but its the element of no quick way of (reversably) shutting off a stream of scalding water in my direction if I fuck up, thats whats stopping me from just doing the whole thing myself.
Few hundred quid is entirely fair and we are ready to pay it. But like, £200 or £800? I'd also have to take out the kitchen cabinet from under the sink which is a pain, so there's that.
For context, we're paying about £200-£300 a month under market rate, and our landlord cancelled the maintenance contract with their management company ~1.5 years ago because we've been on a yearly rolling contract for 7 years and never once went to them about fixing anything, we just got it done (and told them about it).

Dear plumbers of LFGSS, Ive got a leaky radiator valve which should be a walk in a park, but our flat is on a communal heating system with no shut-off valve from the main circulation. Old house, not new-build.
After some research I think my options are:
1, Get a plumber to install a shutoff valve & change the valve / change the valve myself afterwards
2, Get a plumber to change the valve, my understanding is that this would happen with a freezing kit
3, Rent a proper freezing kit and change the valve myself
We are renting the flat, but the landlord is great so Im inclined to negotiate doing option no1 at our cost and time in exchange for no raise in rent for the next contract. They'll probably say yes to save themselves any hassle.
What kind of cost am I looking at here? Am I in the right ball park that for a plumber this should be a ~1-2h job for no more than a few hundred ££?
