I have included enough regulaion # surrounding load monitoring and the need for it, for you to run rings round Ohme when they call you on Monday.
It would also be useful in your discusion with Ohme to inform them of your maximum demand to add, to above regs.
If you list the Amps of the MCB’s in your consumer unit, I will gladly work that out for you!
From what I can see crystal EV charging, is a spin off of crystal electronics, who’s website has been down, so can’t get their accreditation number.
