I cannot see where you have confirmed there is 240V at the valve motor. Is there 240V at the MS?

Just noticed that I did not write the above correctly. One cannot edit the posts, so

I meant to say:
If there is 240V at the MOTOR, has this been tested across L&N? (as opposed to a neon screwdriver etc

Is the motor driving, when energised, at all
 

Hi,

Sorry for the delay. I've checked this myself and can confirm that the valve is receiving 240v. So either it's a fault with the motor, or it isn't wired properly, so won't operate. I took a picture of the Nest box and it looks a little strange. As you can see from the picture below, I have drawn a red circle around numbers 4 and 5. Although there is cables connected to this, there is nothing connected at the other end in the junction box. There is a brown wire sort of hanging but not connected to anything. I can take a few more pics if it helps. Thanks!

Wired wrong

4 is no heat/no call best get it wired by a pro
 
6 is call for heat for hot water
Oh! Then it definitely isn't wired up correctly. Should I move them one step to the right? Here's the other end of that cable in 4 and 5. It literally isn't connected to anything. I don't know if it has come loose or what, but surely this is the reason why it is working? Now the question is, where do I connect these? Thanks a lot for the help. Really appreciate it!

no best to get it re wired
 
You cannot do that job over a forum or the phone mate. Looking at the picture of the junction box it doesn’t look wired in as standard. Needs a clued up heating engineer to wire it in correctly. I know you wasn’t happy before when I/we questioned your sparky and engineer but sadly our experience tells us that this is quite common. Hope that you get sorted mate

Thank you. It wasn't necessarily folk questioning the electrician; it was the comment that said get a new electrician and plumber without any reason why. That comment wasn't really of any use however, once the reasons were explained, it made more sense.

Thank you. I'll just have to get someone you specialises with heating and themostats in particular and go from there. At least we now know what the cause is (hopefully). Thanks to everyone for your input!

Where about are you in the world?

I'm near Belfast in Northern Ireland. Cheers!

Not far from me, before anyone mentions that.
Wiring would need all checked by an electrician or heating engineer who are used to heating system wiring.

Oh, nice. I'm not far from Mallusk if that narrows it down a bit. I might call in your services if you're available? Appreciate it, cheers! :)
 
Ok, so after closer inspection the wires are connected to 5 and 6, not 4 and 5. Sorry about that. 6 I understand is the call for heat and this appears to go back to the boiler. 5 is not connected to anything on the terminal block. The valve gets power from somewhere for sure but what I don't understand is, what wire sends the signal to the valve to open from the Nest control box? It could still be a faulty valve I suppose provided the call for heat connection is going to the boiler. I can hear the Nest box click when I request hot water but the valve does nothing. Thanks!
 
Wire 6

Thanks. Wire 6 on mine appears to go back to the boiler and not to the valve, so I guess that is incorrect then?
 
As said before re wire time
