if I link the "A" terminal to the "B" terminal there is still no power to the boiler. If I link the Live feed to the "switched" Live outside of the BDR91 using a terminal block all is fine, and the boiler powers up.

What happens if you link L to B on the backplate (check both L terminals)?

Thanks for all the advice and suggestions. I'll give it another go this coming weekend when I can have the power off for a while and will update after that.
