Thanks everyone for your help.
Got the Nest installed today. Had to do a little bit of fiddling around but got there in the end.
Not overly happy with having it on the wall with the wire running down the wall but not much I can do about that.
Dont like the stand much and havent got the 12v supply. Dont suppose itd be too hard to wire up but thats a job for another day!
@jackthom - Thanks for the help with the boiler issue. Looks like it could be a pain to fix.
Am I right in thinking Id need to wire a permanent live from somewhere (where?) to the boiler and then move the switched live over to terminal 4 (assuming this is the orange wire that runs back up to the ZV's? These all group together into terminal blocks in the airing cupboard.
Have I got this right? The output of the ZV switch (orange wire) becomes live when the motor operates, which at present in my broken system, is the switched live in my boiler...?
However it should go to terminal 4, which is actually the switched live?
