You should have the single version of the Hive with the connections as below:

From the BRD91 the wire in terminal (L) goes to Hive terminal (L) 'Permanent Live'

From the BRD91 the wire in terminal (N) goes to Hive terminal (N) 'Permanent Neutral'

From the BRD91 the wire in terminal (B) goes to Hive terminal (3) 'Heating On'

Insert the wire link between Hive terminals (L) 'Live' and (1) 'Common'

I should point out that whilst of course it will work, the incorrect cable has been used for this installation and an earth wire has been wrongly used as a live conductor. Also the cable at the boiler doesn't have its outer sheath under the cable clip, instead it is clamping the wires.

Thank you for your help , It was the earth (live) wire that was throwing me .

Post a photo of the wiring connections you have made to the Hive backplate and I will have a look.

Edit
What happens when you press the ‘central heating’ button on the receiver? Does the green light above it come on? Does the boiler come on?

I took the receiver face of again and I had not fully tightened the screw and the link wire into 1 ( com) had come loose, all wires now double checked and double tightened , switches power bk on and bingo All working fine thanks for your help stem it was much appreciated
