Thank you everyone.
Solved..... turns out the wiring from the Honeywell type V4600e was wrong since install (2006) the earth and neutral. This was never picked up until we had a new RCD consumer unit.
Heating/ boiler comes on no problem now.
Very much appreciated.
I will look into the switched live issue with the wiring center.
Thank you everyone for your comments.
