Gas meter moved by British Gas, but....

Thanks everyone - to update, I've spoken with SGN who confirmed they should have moved the earth bonding. The local works manager is going to call...

The bonding is supposed to be within 600mm of the meter, or 600mm from where the pipe enters the house. And if the pipe divides, then before any tees.

Main protective bonding conductors should connect to extraneous conductive parts where they enter the electrical installation (as near as practicable to the point of entry). They should not run to an external meter but to where the pipework introduces its potential (generally Earth potential) into the building.

It is merely gas pipe benders who have this incorrect fascination with it running to the external meter. They are wrong and will always be wrong. The IET Wiring Regulations scream that they are wrong but this doesn't seem to stop gas men from expressing invalid and incorrect opinions.

Also there is no such thing as "Earth bonding". Earthing and bonding are completely different and separate concepts.

I see you have posted on 'bonding' on other sites as well. I am a humble home-owner who has been told by a qualified gas engineer that I should have an earth connection to a gas pipe within 600mm of the gas meter and before any joint, and I have seen the 600mm figure quoted elsewhere as being a 'regulation'.

There is a strap with an earth wire to the gas pipe that would have been within 600mm of the original meter, but which is now about 4000mm from the new meter and after a joint which goes to the boiler. The meter was moved at the request of Southern Gas Network because they didn't want to dig up the side of my house and the living room floor to fit a new gas supply pipe.

Your post still seems to me to say that this is not acceptable. Is that the case?

It's not an Earth connection - it is main protective bonding.

It should be as near as practicable to the point of entry to the building (before branch pipework etc. and preferably within 600mm). It should NOT be running to the external meter - the whole point of it is to ensure that the extraneous pipework is at substantially the same potential as the exposed conductive parts within the electrical installation and therefore must connect where this enters the building.

A qualified gas man is not a qualified Electrician and never will be. Don't seek electrical advice from them. Plumbers are notorious for having an extremely poor understanding of electricity and electrical safety. Gas men are plumbers with a gas qualification.

Gas plumbers are NOT experts in protective equipotential bonding.
