TRV Continuously Shutting Radiator Off

[Associate]

Thank you for all your help guys!

I will take everything on board.

I just wanted to ask for my own reference- if we didn't
get anyone to rectify this fault and left things as they are,
apart from the inconvenience, could this cause any long term
problems or damage to the system if we leave things as they are?

To clarify, when we wake up first thing in the morning and the Heating/Boiler is off and all radiators TRVs are off, and when the Heating is turned On we only want this particular Bedroom radiator or Hallway radiator to be On.

The radiators will have cooled down overnight, but that doesn't mean they are off. If the TRV has not been touched, i.e turned down to the lowest setting, the room will warm up, when the heating is turned on, until it reaches the temperature set on the TRV.
