After some advice please. Been to carry out eicr today, property is only one year old. No problems on any out going circuits from consumer unit. But tails run well over 6 meters and are buried less than 50mm with no additional or mechanical protection. This been designed to 17th edition I gave a c2, company I’m working for have rang nic. Who are saying it only warrants a c3 has it’s not potentially dangerous. How can something that should have failed initial verification but got passed suddenly be satisfactory? Surly original installation cert would be fraudulent really?
