Flats Gas Meter Bond

[bilbo_88]

Hi All

Divided opinion over here so thought we would get a bit of advice.

Block of 30 flats recently had gas meters inspected and during a visit the National Grid issued the landlord with a letter saying that none of the external meters had any bond within 600mm as per regs.

Now I would have assumed that bonding would be local to each flat therefore where it comes into the building rather than at the meters for practical reasons (I'm sure I was told this as an apprentice) but now it's made me doubt myself and think should each has meter have a bond from the MET as most of the flats are owned and it is not practical to inspect each one for a bond.

Any second opinions before I terrify the landlord with a quote?

thanks in advance

i completely agree with geoffs interpretation.

with the regs book open in front of me , its clear as crystal - the 600mm connection point recommendation is to be applied to just internal meters , for external meters , bonds are connected as close to building entry as is practical.

position of the gas meter is​ relevent when deciding where to bond your pipes.

Before the 16[SUP]th[/SUP] a jumper would be fitted across the meter, I wonder why?

The point of service entry and the consumers installation are covered.

No, size the CPC/bonding to the distribution circuit supplying each flat, same as you would do for any normal house supply!! Personally, if SWA cables are being used for the flats supplies, i would use a 3 core SWA, it makes life so much easier and is cheaper overall than running in a separate cable with a 2 core SWA cable, especially when you are talking about 30 runs of cable...

Only the connection between the service cut-out PME connection and the building MET (to which all of the flats EMT's should be connected to) needs to be a minimum of 35mm or greater.

Thanks E54, I guess I was thinking along the lines of a single PME supply serving multiple separate buildings. If you can class each flat as a separate 'house' supply for these purposes that makes things easier. I have never worked on houses either so have limited experience. Again thanks for the info.

And now since the jumper is no longer there we are required to fit a temporary bond (jump lead affair) whenever we remove a meter - all of which would be unnecessary under the pre-16th.
