I have just found out that one of my downstairs lights ( metal chandaleir ) has its eath feed connected to a central heating pipe !! Is this OK ? It must have been this way for ages and only came to light when I lifted a board to look for a heating leak...
Lighting earth from heating pipe ?

No, it's not OK.
If the wiring is lacking a CPC (earth) and you have class 1 items on the circuit (which you do) then you have no choice but to have the circuit rewired.

There is a CPC as well as the pipe connector and both test 0.3 Ohms back to the MET ( when pipe cable disconnected fro light fitting ) Wiring is to 17th and all bonding is in place... Should I just cut this wire off or leave it?

So you're saying that the light fitting has a CPC as normal, but there's also a conductor going to a clamp on a CH pipe?
If so it sounds like someone's supplementary bonded it - I've no idea why they'd do that, but hey. Assuming your chandelier isn't in a bathroom
- just disconnect it.

but the light is in the dining room.I'll just leave the extra wire off..
does the CPC deffinatly read back to the board with the 'bond' disconnected?
Downstairs bathroom in close proximity?
Yes it reads 0.3 ohms. Just had a thought the wire must have been connected long before the present earth bonding was installed, I can also remember a wire from the earth conection on a downstairs ring being connected to the gas pipe. House was 2 flats originally and there was a separate heating system in each one. I had a combi fitted and the plumber "married" the 2 systems together at that time.
