I have changed a radiator on my Vaillant combi boiler operated central heating system. How do I bring the pressure back up to a sensible operating level?
a video on how to solve your problem. Why the plumbing industry creates a mystery around a simple process, God only knows.

I have a flexible pipe OK but it isn't connected to anything. I can see a threaded connection to which one end will fix but nowhere for the other end to connect despite a thorough search

somewhere near the boiler, you will see a flexible pipe connected with a valve on, that is used to refill, turn it on slow, as you do not want to go over pressure
