If and I say If his interpretation of the regs and certifying is correct as it stands them I am sure that it is not what the writers of the regs intended.
I believe some clarifications are comming in the near future and hopefully this issue might be one of them.
Until such time I`m erring on the side of common sense and using the "add to a ccct requires the addition only to be to current regs" similarly say a shower in a bathroom then the shower will be to the regs but any existing cct not nessacarily uprated (Supp bonding carried out though).
Even before the economic downturn the 17th has caused problems with contractors implementing them re costs to customers but this would kill trade stone dead - unfortunately we work in the real world
