Where to bond?

[Chops]

Been to a domestic installation today and found that the water and gas are not bonded. The water appears straightforward, however the gas is not so.

The gas service currently enters the house under the floor. A heating engineer has previously teed off here and taken a supply back outside the house and up into the loft to a new boiler installation.

Where would you guys bond to? I'm not keen to bond under the floor - access issues for inspection etc, although this then means that I'm bonding after branched pipework. I could bond outside, near the ground, and run the bonding up the outside wall and across the loft towards the MET on the other side of the house. This may lead to mechanical damage or corrosion issues. Or I could simply bond in the loft where the gas pipe enters.

Any thoughts?

Well thats the contradiction. I cant satisfy all aspects of the regs here. I cant bond within 600mm of point of entry and before branched pipework and at an accessible point.

It has to be two out of the three. Which aspect do I not satisfy?

Chops

but the regs aren't statutory they are guidelines so if you can justify your choice and you have done what is reasonably practicable i don't really see a problem ( tin hat on) . So to my mind it's up to you and your decision is right.

location if not obvious?? does that mean anywhere on the pipework as long as it's labelled on the db? where is that in the regs just out of interest?

hi there

i would suggest you find the gas meter and bond within 600mm before the first branch.

in the cabinet if poss then run to main met

you should not bond under the floor as it is a requirement under the gas regs for access and verification i think this is correct

anybody feel free to please correct me if i am wrong

if you cannot then it is at the first entry point to the building based this assumption from the advice given in the domestic corgi book

chops has already said gas meter is 50metres in front of property and first bend is under flloor.

Thanks for everones input. I'll forget about under the floor. I will bond where the pipework re-emerges outside the property and then loop into another bond clamp in the loft for belt and braces in case of mechanical damage issues to the outside clamp in the future.
