Bondage, no wait, Bonding for gas supply/eqpt

KingL

I have a flat on the third floor with a combi gas boiler.

I am thinking of renting it out (the flat, not the boiler) and I got a Gas Safety inspection done. The inspector noted that there was "no equipotential bonding evident" when he looked at the gas meter, but said that this didn't constitute a fail for the gas safety cert.

I am contemplating his recommendation to get an electrician in to provide the bonding. But I'm not sure where the bonding is required and, thus, the scale of the job.

Is it just between the Gas meter and earth? (the gas meter is in the basement and this would (presumably) be easy to do. Or is it between the boiler and earth (the boiler is on the third floor and it would be a hassle running a new earth cable down through the building).

If it makes a difference, the water main from the basement to the flat is mostly PVC, but the gas supply is copper all the way. There is an existing bonding cable from the copper pipes on the kitchen sink/washing machine (in the same room as the boiler) down to earth.

Is this going to be a piece of cake or a massive undertaking ?

You need an electrician. Equipotential bonding would normally be from the electricity meter cupboard to your side of the gas meter & onto your water pipe.

But it depends on the type of electricity supply you have.


I am surprised you can get a gas cert without it but I am new to it & am still learning.

Thats the key. Just because he couldn't see it it doesn't mean that it isn't present. BUT it is supposed to be visible to satisfy regs. So someone has to ferret about a bit and see if they can find any before you start thinking about fitting new.

usually a 10mm earth from the earthing block by the electricity meter to the gas meter, can't remember the exact spec bit 50cm from the incoming pipe I thinlk (I wait to be corrected)

Brilliant!

Bondage

I think it's 600mm from the outlet or near as practically possible.

Within 600mm of the gas meter and before the first tee in the pipe work, are the gas regs. Electric regs are at first point of entry into the building, I believe. Why they cannot match these up is anybody's guess!

A landlord certificate is not a pass or fail certificate, it is just a certificate stating the condition of everything gas at the time of the visit.

No earth would constitue a label stuck on to advise that the earth needs to be checked by a competent electrician.

The incoming gas supply TO YOUR FLAT should be bonded to your flat's main earthing terminal, where it enters your flat.

The gas main should be bonded where it enters the cellar to the main earthing terminal for the cellar's electrical supply, which may be the landlord's supply.

Both METs should be bonded back to the building's MET which will probably be where the mains electricity splits off into submains serving the individual flats. Bbut if it's an old conversion from a house the whole system may be a complete lash-up.
