Stellar advice thanks. Sure this would be a simpler approach that tracking the wiring back and reading the manual for the boiler. So the common wire will carry 230v while the heating on wire will be carrying no voltage?

I see, thanks. Would there be an alternative way to identify the common wire i.e. is there a safe test that can be done to see if the wire carries 230V or not? Thanks

I've tracked it back and one of the black wires eventually connects to the blue wire housed within the same original group of wires. Would this make it the common wire?

Ok thanks, in that case I'll need to track it into the boiler. If I were to connect the wires incorrectly, i.e the common wire to the heating on port and the heating on to the common wire port, would this damage anything or would it simply not work?

Hi, I'm just replacing my old thermostat and programmer with a Hive active heating one. The previous thermostat and programmer had wires running into another room where they were displayed and I'm planning to fix the receiver unit much closer to the boiler. As such, its not a straight swap out...
