"Theres only 1 rcd for the whole circuit (i know, its an old setup) and 2 wylex fuseboards for on peak and off peak."

Unless I'm being thick and missing something already covered, how can you have a single RCD covering two lines of supply?! In order for that to be it would have to be upstream of the meter, which it never would be unless the meter fitter had been smoking something herbal at the time.
Yeah I wasn't sure if it covered both boards or not as my knowledge is limited.
Is it possible to do so by using the henley block or is it the case that the RCD just covers the on peak fuse board?

On the original setup the meter only had a Single L & N out to the C.Us
This went direct to the RCD, through it then to the Henley where it split.
1 L & N supply to the Main C.U
Another Live went out to the contactor by the meter and came back in off the switched side to the Off peak Consumer unit.
The L to the Off peak now comes from the meter and misses the RCD, but the Neutral doesn't
Yeah I think I get it, basically with the new meter tails configuration it has circumvented the RCD so that when the off peak board energises the rcd only gets half the picture and trips. Do you think this means my equipment is not faulty and I just need to have the RCD reconfigured on the circuit to work with the new arrangement then
