This has all been very interesting to read all the opinions.
But I did expect a closing posting from Reading1986 saying if and how it has been resolved.
Although I do little work on radiator systems ( specialising in boiler repairs ), I have to say that if I was confident that I had fully drained the system and it needed further work the next day then it would be possible that I would not waste time capping off rad valves etc. or closing bleed screws on rads which were to be removed the next day.
But the ESSENTIAL work that any competent person would always do is to remove the filling loop and cap off the inlet valve. That would ensure that the system could never be pressurised without the use of tools.
As for testing systems, on a house where I was fitting a new boiler I needed to remove about 8 m of 15mm copper gas pipe. On this length there were TWO fluxed but UNSOLDERED joints that had lasted through 15 years of occasional gas leakage tests!

Reviews on some of the Find a Tradesman sites need to be taken with caution.
A lady I knew had a clutch replaced but they put a rotation locking washer in backwards and within days the car would not start when hot. ( The flywheel just turned on the shaft! )
When I looked at reviews on this "Clutch" place I saw that virtually ALL the good reviews were for very simple jobs like replacing clutch cables.
The test for any trade is if they can do the more difficult jobs as well as easy ones!
