Would a cheep snake cam do a job while you wait for the contact of the guys next door? On semi related note, just ordered one on Ali to investigate rad that is not working and seem to be empty (it should be on CH, cant find any valves). Son of previous owner (RIP) made some comments how weird it was for them to move to place where all rads were working. Though he vaguely remember it working long time ago. So some shenanigans afoot.
Check that the system is balanced, or at least get someone experienced to do it. Had one place that was a struggle until I had a plumber balance all the rads.
