Thanks again for your help. All wired up and working.
Does my wiring look ok? I guess I've done a bit of a naughty and used the earth in the 3-core connecting Hive 1 to Hive 2 for splicing the CH2 wire. I've labelled both ends but guessing that's frowned upon? And 3 wires in Hive 1 N-L...

Ok I use the main red switch. Thanks for pointing out the incorrect labels; it's a Taylor Wimpey new build, go figure.
Out of curiosity what risks are involved with just switching off the MCB for heating and testing for absence of voltage of the live wire and then working on that circuit?
Thanks for your reply. I turned off the heating switch as in the photo below of the consumer unit. Is it safe to be working on that circuit if I do so?
I could always flip the main switch if that is safer?
I am replacing a Hortsmann h37xl and switched off the heating RCD, tested the live wire to make sure it was off and all ok. When removing the Hortsmann one of the earth wires touched the neutral wire connected to the Hortsmann and tripped the whole RCD unit. I am a novice and wondering if...
