boiler engineer or electrician?

[plumber0808]

Another tip is if as an engineer you are ever in doubt or concerned about pipes or wiring in your working area, firstly do all the checks you can to ensure it is safe, and if still concerned only touch things with the back of your hand until confirmed safe. The reason being is that if you do touch a live, your muscles spasm and grip on to whatever your touching... If its RCD protected you just get a shock. If its old style or somethings faulty, you might get fried, and if no ones there to get you off it, you are in big trouble!

If you do get help off your mate hope he don't just try to pull you off or you will end up with a daisy chain of dead plumbers. RIP in heaven we will unite

As all have said above , There is a serious wiring error. If the earthing was correct then the RCD's should be tripping. So deffinately a wiring fault and incorrect earthing arrangement.

Ok. Update. It seems the boiler engineer was right. It wasn't anything he did that caused the problem. The fault was pre existing. Two things came to light following an electrical inspection today. Firstly, someone had disconnected the earths in the main fusebox and secondly, when I put a picture up in the lounge a few years back it seems that I drilled through a cable. Not content with drilling through it just the once...oh no...i had to drill through it three times before I was completely finished! So it was my fault. The installation of the boiler simply served to create a new 'quickest' exit point.
