& @Airhead thank you both, appreciate that my woeful explanation/knowledge on this probably makes it hard to help.
I’ve added photos of the controller and of the boiler itself. For the sake of this photo I’ve switched the heating on the controller to “on” but I’ve had it off for the last week because it makes no difference. When on it doesn’t actually control the radiator output to get the current temperature to the target temperature.
On the boiler, the radiator symbol is currently blinking every couple of seconds which indicates that it’s active and working as expected (according to the manual) which does make sense. That works as expected in line with whether the radiators are on or off, but doesn’t correlate with the thermostat settings. That’s the bit at the end of Airhead’s post which is throwing me off completely - surely if I have the heating turned off at the thermostat the radiators shouldn’t do anything regardless of whether they’re individually open or not?
The set up in the old place was about 20 years old and far easier!

It sounds like the boiler is being told, or set to continually heat. This is not the default setting.
Two possibilities
- the boiler is set, somehow, to continually run the heating circuit, or
- The thermostat/controller is set to permanently call for heat and bypass the thermostat. This is weird behaviour because the ‘cont’ setting usually heats continually but is ruled by the thermostat.
If you are feeling brave resetting both to factory settings then let them re-pair again might sort things out.
But its possible that the current behaviour is the result of some bodge repair that someone did at some point.

You have it set to "on". You want it set to "auto" I think, assuming I can remember how it worked in our old house. On is on all the time, auto will follow the schedule and listen to the temp setting you have programmed.

Is the thermostat one of the old dial types? Can you hear it click as you adjust it?
