Domestic Electrical Issue - Live Volts in House but Not Getting Shocks. Any Help Appreciated

[R Yates]

Hi All, firstly to introduce myself I'm not an electrician but was hoping to get a bit of advice on an electrical issue I have. Basically we wanted to get a boiler service but the plumber would not touch the boiler as he said we have electrical volts running through the house (radiators, sink, boiler, plug sockets etc). There is a link to the videos below to explain this.

We are not getting any shocks and apparently it is running through all circuits in the house. Every electrician we have talked to is baffled by it. I was wondering whether anyone has ever come across this and what advice you may have on how to proceed/what may be causing it?

Many thanks in advance as I appreciate this is a first post.

I do hate it when people call them plug sockets. They are either plugs or sockets but never both.

I suspect a good proportion of the 64 million people in this country do, along with light bulbs. I can think of more pressing issues, like tea time versus dinner time

I had a customer getting a slight 'shock' off a brass light switch, my MFT measured 75v ac from the CPC to the radiator below. It wasn't a constant ac tingle, more like a static electric zap or a capacitor discharging. Powered it down, checked R2 with a wander lead back to MET, no continuity. Tracked back along the ceiling roses and found the CPCs not joined where someone DIY had chucked up a nice B&Q chandelier. Restored the CPC, meggered the circuit to make sure no damage/leakage, and powered up again - 75v ac gone, no tingle any more. As the insulation resistance was all fine, I can only assume that the stray voltage was induced from phase to CPC? And since the CPC was broken, it had nowhere to go it stored it like a weak capacitor?

Any thoughts on this?

Could this be what the OP is experiencing, but for the whole property? (I.e. There is not a solid earth connected to the property?)

Appreciate all the replies and help with this and apologies for the delay my side, had to work out of the country on short notice for the last few weeks so have only been around briefly on weekends. Cancelled the electrician who was coming out due to the above so Telectrix I will pm you now about it.

Cheers all

update on this:

R.Yates sent me a pm asking me to sort it for him. I called yesterday and initial tests showed 241V L-N and 148V L-E. no reading for Ze. as suspected, it was an earth fault. wander lead out and proved continuity of MEC from meter E block to CU (PME system, house built c.2000). fault was the N-E link inside the cut-out was not tight. 1/2 -3/4 turn on each screw resolved problem, Ze 0.15, Zs @ random socket 0.55. done and dusted in an hour and a half.

Many thanks again Tel. Much appreciated and glad to have it sorted.
