Electrics and negotions with Central Networks for a PME

This is a saga I'll condense, it could be useful for anyone else in the same position. I did loads of internet searching and found it crops up quite a bit. On this occasion I won and got the result I wanted.

The electrics for the loft have to be certified for the Building regs approval. The testing includes an Earth continuty reading at the consumer board - a ZE reading, this was too high to pass. Our system is a TNS, this relies on an earth supplied by the supply company. Ours had an earth strap bonded to the outer sheath of the incoming mains cable.
Two ways to rectify this
1. Fit a earth spike and have an RCB - not always reliable as the quality of the earth depends on the moisture content of the ground.
2. Fit a PME that uses the Neutral supply as Earth - The supply company has to fit this and wanted to charge £75.

Me not happy, my Electrician believed its the responsiblity of the supplier, and 17th edition regs backs his opinion.

Lots of negative/ blocking tactis from central networks lead me to get a case started with Energywatch. I then got escalated to specialist customer services team and my own very nice but not technically minded young lady to talk to.

After many calls and two visist from engineers I was still getting nowhere. The engineers just tested the supply and said its fine and I could apply for a PME to be fitted. I eventually got a goodwill gesture of a half price PME.

No Deal. I started getting tchnical again and explained they changed the wiring in road years back and fitted the rest of the street with PME, they missed us out and had left us with a potentially dngerous supply for the last 20 years. "Before privatization, thats not our responsibility" yeah that line didn't last long. I then got to talk to an engineering manager who understood the problem'ish.
He visted, had a look and without admitting liablity, fitted a PME in about twenty minutes to shut me up and close the case.

So persistance paid off, they could have done it earlier and saved us all alot of time and their expense.

Electrics where plain sailing after that, using a supply cable (from a previous shower instalation) to a two breaker box, one for sockets and one for lights. All works and up to spec.
